astra 2 satellite problems 2019

The weather can seriously affect satellite reception, rain. In the case where the modulation scheme transmits 1 bit per symbol (e.g. History. This is the signal strength of the Intermediate Frequency (IF) output from the LNB. I have a similar Inverto Black Ultra, again chopped and glued for C120, this gives 5% better results. DVB-S2, 8-psk, FEC: 8/9, C/N at QEF: 10,7 Signal strength is the percentage of signal to noise ratio, the measurement of signal strength from the LNB to the receiver. Bit Error Ratio is an objective measure of the quality of the digital TV signal after signal demodulation. Symbol Rate (SR) is the number of symbol changes (waveform changes or signalling events) made to the transmission medium per second using a digitally modulated signal. Interpretation … All these reading as done with a Inverto White Quad LNB , which has been chopped and glued to a C120. Optimum NF is probably in the middle of the band 10.7-12.75 GHz. Temporary Obstruction of Satellite Dish – Scaffold etc Inverto black ultra LNB. Have fine tuned dish but to no avail, cannot get slightest signal when trying to tune to a BBC or ITV channel. The PF 1.8 m dish is optimized towards Astra 2F so maybe I could get a little stronger signal if I fine tune the dish towards Astra 2E. Reception: Intermittent reception and breakup. The coding techniques, which are employed in the digital TV standards, are able to identify and correct a certain amount of errors. Dishes are usually sized by their diameter, so size can be confusing if you are not comparing dishes of the same shape. In order to locate 28.2°E - Astra 2A, Astra 2C, Astra 2B, Astra 2D with Sat-direction, all you need to know is where you are and know how to look at a map. Skew varies from about 15º in the north of Scotland to around 22º in the south west of England, always rotate clockwise as viewed facing the front of the dish. In the northern hemisphere, sun outages occur before the March equinox (February, March) and after the September equinox (September and October). The international version is shown as free-to-air on Astra 1L at 19.2° east. This morning I woke to a loss of BBC (ex 1N) Verticals but Horizontals (except HD) were OK. Channel 5 from Astra 2F was also OK. Part of the data stream is used solely to correct errors in the downlink stream from the satellite. Peter should soon fill us in anyway and his usually very accurate. Satellite and channel information updated daily. Sky channels on the three Europe beams are stronger than before in most of the continent, though there have been exceptions, such as in the eastern Mediterranean. Basically you need: • A satellite dish antenna pointed at Astra 19.2° Est • An (at least) HD satellite receiver (it can be an external set-top box or a built-in television tuner) DVB-S2, 8-psk, FEC: 4/5, C/N at QEF: 7,9 Consequently, bit errors can be tolerated up to a particular level without causing quality degradation of pictures or sound. The constellation diagram allows a straightforward visualization of this process — imagine the received symbol as an arbitrary point in the I-Q plane and then decide that the transmitted symbol is whichever constellation point is closest to it. 1) broken the joints, messy and VERY difficult to re-align. Reception of all Astra 2E UK spotbeam channels. This prevents the picture breaking up. Although it may seem just like another addition to the tracks of a hackathon, its upside potential is virtually unlimited. The “threshold of visibility” is another term sometimes used referring to a rate of errors that just becomes noticeable to a TV viewer. Available on iOS and Android the free app, called ASTRA Instalación Parábola, aims to increase the usage of the Astra 19,2° East orbital position with hundreds of FTA channels. Modualtion and SR change from DVB-S2 QPSK 27500 to DVB-S2 8PSK 30000. 1. 2. We have two satellite feeds (28.2 and 19.2) and a digital aerial feed connected to the TV. Low signal strength readings can be an indication that there is a problem between the LNB and the receiver, this could be caused by defective connectors or cable. Reports suggest that a 1.8 m dish gives reception of the Astra 2E UK spotbeam 24/7 (NOT CONFIRMED). Which ever type of modulation is used, QPSK or 8PSK, they all use a form of Forward Error Correction (FEC). The effect is due to the sun’s radiation overwhelming the satellite signal. When you have a large dish looking at high power satellites, the gain can be so high that the receiver is overloaded with signals. European beams on Astra 2E/2F from Rotterdam to Baltic Sea • Satellite name and angle (i.e. The service was formed as a memorandum in 2007 and has been marketed since 6 May 2008. Most of the (HD) channels I want have vertical polarization. I’ve also tested to receive Astra 2E with a 100 cm Nokia offset dish which works fine for the horizontal transponders but not for the vertical ones. The Freesat electronic programme guide is broadcast from the Eutelsat 28A satellite situated at 28.5° east. The receiver should operate with signals up to 100%. Steady signal all day.But what about tonight??? longitude i.e. Astra is the brand name for a number of geostationary communication satellites, both individually and as a group, which are owned and operated by SES S.A., a global satellite operator based in Betzdorf, in eastern Luxembourg.The name is also used to describe the pan-European broadcasting system provided by these satellites, the channels carried on them, and even the reception equipment. 3- Centre conductor is too short and not making a reliable connection ‍ If you need help performing common coaxial cable terminations please see out DIY Video guides . I can receive all Astra 2F transponders both horizontal and vertical with a 100 cm dish. When it comes to the PE beam 2E is a little bit stronger than 2F. Sony support does not know much (hardly anything about the subject), and I cannot find an answer on Google. If anything it has improved, as I can now can use Planner at all times, where as before only in the morning for about 1 hour. Sky Digital: New frequency for BoxNation: 11081.00MHz, pol.H (DVB-S SR:22000 FEC:5/6 SID:50301 PID:2305/2306 English- VideoGuard). The Astra 2E transponders are weaker compared to Astra 2F transponders. Low signal strength readings can be an indication that there is a problem between the LNB and the receiver, this could be caused by defective connectors or cable. The satellite appears to be tilted as viewed from Earth, this means the LNB has to be tilted to a similar angle so that it matches the geometry position of the satellite. Weather quite gusty with light clouds and light rain/drizzle, not perfect for standing about too long with unstable mechanical “installation”. It is a measure of how “good” the signal is and how “easy” it will be to demodulate the transmitted information. I think the dish alignment is probably OK (and I wouldn’t tackle that anyway). Keep the cable dry and above ground level, never place it underground unless it is placed and protected by waterproof piping. Currently, most UK PSBs use a FEC of 5/6, which is not very robust in fringe areas. If the missing carriers are all in one band then the 13/19 supply voltages are the problem, or the LNB. Lund, Sweden 1,5 – 1,6 m dish in central Lund. In pure phase modulation, the phase of the modulating symbol is the phase of the carrier itself. ALQUILER HD. It is less efficient, with not so much data available to transmit the picture. The signals are definitely down on what they were, previously all were about 97 to 100%, even though the dish was probably not set up perfectly (but good enough). Plotting several symbols in a scatter diagram produces the constellation diagram. This is maximum likelihood detection. These can ‘swamp’ the lower powered satellites signals. I have a 1.8m dish & 2 x EchoStar HDS-600RS, which are probably not the best receivers for fringe areas but are excellent boxes for day to day use. Although other elements are important in the reception chain, such as LNB type and the type of receiver used, there is no substitute for more signal from a larger dish. Theoretically, the lowest noise figure obtainable from any device is limited by any components in the signal chain with the highest thermal noise. Problem tuning second satellite (astra 1) to XF85 sony bravia TV Hi, We recently go a 49 inch XF85 tv for our newly built house here in Ireland and are having trouble tuning in the second satellite feed to pick up the german channels. Launched in 1988, Astra 1A was the first satellite in the Astra 19.2°E group. The effect sweeps from north to south from approximately 20 February to 20 April, and from south to north from approximately 20 August to 20 October, affecting any specific location for less than 12 minutes a day for a few consecutive days. The LNB is kept in place by either a screw or a nut. Dish No.1 SMW OA 1400 polarmount FEEDHORN: SMW XM-140 LNB: Inverto Black Pro nf 0.2, RECEIVER: DM 7020HD & Moteck V Box II 36V, Receiver: Humax Foxsat HD & MegaSat HD500. Always use the highest quality cable, damaged or poor quality coaxial cable will reduce the signal levels delivered to the receiver, causing lower or loss of signal. CNR (also C/N) is the carrier to noise ratio. measurement of signal strength from the LNB to the receiver. All of the BBC’s  domestic radio stations which are on satellite, use Astra 2E. Official satellite reception maps (footprints), have very conservative values, this is good if you are inside the official reception area, as it is easy to determine the dish size required for reliable reception. To Sky or not to Sky at 60 odd quid a month, that is the question. Presently the LNB market is active by those selling what appears to be an extraordinarily good device, some use the best of the component batch – and end up with good performance overall (rare). A sun outage, sun transit or sun fade is an interruption in or distortion of geostationary satellite signals caused by interference from solar radiation. 75/75 Strength/Quality. At first sight, the highest gain you can get would be the obvious thing to look for; however that is not the only criterion when it comes to LNBs. Introduction / FAQ Define your Profile Most recent updates (News) [+] Most recent additions / changes [-] Most recent removals Most recent updates (News, Clear) Most recent updates (News, Hotbird 13°E) Most recent updates (News, Astra 19,2°E) Satellite Directory Reception Reports Temporarily Free To Air (159) Channel Directory Packages English - Sky Digital - MTV Networks - BBC - Freesat Hope someone can shed some light, I'm running a SKyStar 2, motorised 100 cm dish and My Theatre and I'm chuffed with what I get, but I don't seem to be able to tune in properly to 19.2 east. Freesat broadcasts from the same fleet of satellites (Astra 2A, Astra 2F, Astra 1N (soon to be replaced by Astra 2E) at 28.2°E and Eutelsat 28A) as Sky. The weather can seriously affect satellite reception, rain, clouds, hail and snow can block or reduce the signals. Location Santiago de Compostela, Nortside of city with uninterupted view to horizon. Reception is a tiny bit weaker as 2F here some 20 km southeast of Falun with a signal quality of 20-30%. Since then I am getting a little pixelation on the BBC horizontals, but have lost Channel 5 completely (which is normal). The BBC, ITV and Channel 4 all use this satellite to broadcast their channels. BBC 1 HD is 90/80 evenings and 90/70 for a few hours in the afternoon. :DSimilar trial in October 2013 in same location but better weather for historical comparison purposes: Channel 5 (Astra 2F) and BBC (Astra 1N) Channels Strength 51-80% Quality 51-28%; Lock quickly found with good reception. I have stable reception of all Astra 2E transponders here in Falkenberg on the Swedish west coast with my old 180 cm Luxor primefocus dish. Checked out the reception on BBC channels at 7.30 this morning, seems that was just when they started to switch to 2E! Signal: S 83&/Q 33% on SD and S 83%/ Q23% on HD. Ku-band transponders having a total power of 50 watts have EIRPs as high as 48 or 49 dBw when this power is directed into a tightly focused spotbeam. AXN HD. 27 March 2020. Beam Europe Ku-band beam. The degree of tilt varies depending on both your location and on which satellite you want to receive. 3rd September 2019. Signal: BBC 1 HD 10847 V S 55%, 8.62 dB / BBC1 London 10.773H 61%, 9.38 dB, BBC 1 HD 10847 V on 1N snr 73% dB 11.38 now on 2E snr 55% dB 8.62, All channels Astra 2 E good signal north Sweden Östersund no problem 3.70m Dish. WEATHER – CLEAR -5c, I checked at 0800 CET today and BBC One HD was not available, but BBC1 London was okay with 65/70 Strength/Quality. DVB-S2, 8-psk, FEC: 5/6, C/N at QEF: 9,4 Most of others not available, some ITV’s working. Reception Quality – Freesat Channels all: Very good, some deterioration in heavy rain. LNB: Inverto Quad, ChannelMaster feed horn. clouds, hail and snow can block or reduce the signals. Please remember these are localised reports, reception may vary at your location. At around 10.40 to 10.50 CET, signals from Astra satellites at 28.2º east will be lost completely as they move in front of the sun. SNR (also S/N) is the signal to noise ratio. The BBC, ITV and Channel 4 all use this satellite to broadcast their channels. This is a measurement of the Bit Error Rate (BER) of the received signal from the satellite. Receiver: Humax FOXSAT-HD & Bush BFSAT02SD. Along with other conventional tracks, CUBESAT forms a major part of our hackathon. Quasi Error Free (QEF) The point where the signal quality is enough to give stable reception, a level of errors that is defined as the “threshold” of where the system is working and where it is not. ... 16th August 2019. DVB-S, QPSK, FEC: 7/8, C/N at QEF: 8,2 The points on a constellation diagram are called constellation points. The Symbol rate is measured in baud (Bd) or symbols/second. It will be interesting to see how Stockholm fairs out this time round. This principle of using two independently modulated carriers is the foundation of quadrature modulation. In most cases, signal strength is always strong – around 90 to 100 percent. This determines if the signal being sent is being correctly received without errors. Reception is slightly improved over Astra 1N Adjustment of alignment, very very slight adjustment of dish to North was required with new satellite. DVB-S, QPSK, FEC: 2/3, C/N at QEF: 5,5 To ensure that your dish is large enough you need to know the strength of the signal at your location. At these times, the apparent path of the sun across the sky takes it directly behind the line of sight between an earth station and a satellite. All Sky channels still giving at least 80% signal strength & 90 quality. Effective Isotropic Radiated Power (EIRP) is derived from the word isotropic which means equal in all directions. My current setup is a Gibertini 150, Inverto Black Ultra and a Pace 2600. Sky Digital: BoxNation has left 11344.00MHz, pol.H (DVB-S SID:53205 PID:2326/2327), it is no longer transmitted by satellite in Europe.. Astra 2G, 28.2°E. Unplug the TV (or receiver) from the mains. BBC1 Yorkshire seems now to have migrated to 2E. All geostationary satellites are located above the equator (the Clark Belt). This is not a very difficult requirement to meet, except perhaps at the edges of the band, as long as the LNB is constructed properly. Please remember these are localised reports, reception may vary at your location. The Magicsat has stopped locking on to Astra 28,2E. Each satellite has a transponder number which is what a self seeking system looks for the problem is it gets changed now and again which doesn't affect domestic systems as the satellite stays put as does the house but for mobile systems they need to know the new number. Viewers within the central footprint in the British Isles and nearby Europe should not be affected, those in fringe areas will lose the signals from Astra 2E, Astra 2F and Eutelsat 28A. At Ku band, the detectors are rated at manufacture to about 40K which converts to a figure of 0.5 dB. SR and FEC change from 22 MS/s 2/3 to 23 MS/s 3/4. Channels are broadcast using DVB-S and DVB-S2. DVB-S, QPSK, FEC: 3/4, C/N at QEF: 6,5 Fixed the new dish on the wall just above my existing dish. All BBC working fine no loss as of yet. I have fitted a new LMB just in case. Documented Satellite TV charts dedicated to European viewers. It displays the signal as a two-dimensional scatter diagram in the complex plane at symbol sampling instants. In areas where the signal is strong, skew is not such an issue, once outside the main reception area as with Astra 2D overseas, skew becomes important The LNB is locked in place by either a screw or a nut. Using same dish 100km further east into 2x digiboxes, again in October 2013, yielded: BBC (1N) Strength 78-70% Quality 25-90% with lock and good reception. Measured constellation diagrams can be used to recognize the type of interference and distortion in a signal. It is the power ratio (again usually expressed in dB) between the received (and demodulated) wanted signal power in the baseband bandwidth and the thermal noise at the demodulator output in the same bandwidth. They are a set of modulation symbols which comprise the modulation alphabet. EIRP levels refer to the power of signals measured at the satellite downlink antenna. Used the satellite finder supplied to find the Astra 19.2 satellite, which is facing south, 9 degrees to the right of where the 28.2 dish is pointing, is was easy to find. To let the demodulator in the receiver work effectively, the gain at all frequencies, should be the same. For example, in an analogue FDM/FM voice multiplex carrier the CNR would be measured in the bandwidth of the whole carrier but the SNR would be measured in the 4kHz bandwidth of one voice channel. The effects of a sun outage range from partial degradation (increase in the error rate) to a total destruction of the signal. The result is therefore a slightly pixelating picture that probably is going to get worse in the day with the normal pattern of the footprint. There are many factors to consider in the satellite signal chain, they can all affect how much signal is received by the receiver, thus reducing the quality of the picture and sound. Funny thing is the Channel 5 channels are now available, i had lost these until now. In some situations, as with overseas reception of the Astra 2E and Astra 2F satellites, the dish is simply not large enough to provide a signal that exceeds the satellite receiver threshold for reliable reception. Belgium is inside the official Astra 2E footprint. Signal strength is just an indication of how strong the received signal is. Previously good signal at 1.80m, Soyuz Flight VS24: Mission success at the service of the United Arab Emirates, Successful entry into service of Eutelsat Konnect Satellite. It is finding Astra 28,2,E, maximises the signal but when it checks the satellite, it must think it is the wrong satellite because it then starts searching again. A larger dish is required for reliable reception at this location. DVB-S2, 8-psk, FEC: 9/10, C/N at QEF: 11. The UK Spot beam provides maximum signal (for 45 cm dishes) over the UK and Ireland with a sharp roll-off of signal level outside this region. It will lock on to other satellites. Service 30805. It is typically measured at the output of the antenna or the input to the demodulator. WEATHER – GREY, Rain/Snow -2.5c. List of Television Channels at Satellites 19.2°E Astra ... Satellite Astra 1KR. Upon reception of the signal, the demodulator examines the received symbol, which may have been corrupted by the channel or the receiver (e.g. Even if the receiver itself can handle a massive amount of signal, there can be problems within the LNB itself when large amounts of amplification are employed. Report from Los Alcazares, Murcia – 3 dishes, 1.25 x 1.37 offset dish – Most SD channels, No E4, no BBC 1 & 2 HD, 1.6 x 1.5m offset dish – All channels SD & HD 24/7. It is a Channel Master 2.4m offset dish with Inverto Black Ultra LNB and Amstrad DRX-890 receiver. The sun radiates strongly across the entire spectrum, including the microwave frequencies used to communicate with satellites (C-band, Ku band, and Ka-band), so the sun swamps the signal from the satellite. January 2, 2019 12.12 Europe/London By Jörn Krieger German public broadcaster ARD will transmit its complete TV channel portfolio in HD quality for DTH satellite households via Astra (19.2° East… In the northern hemisphere, sun outages occur before the March equinox (February, March) and after the September equinox (September and October). Listed below are reception reports for the Astra 2E satellite positioned at 28.2° East. S: 85-86, Q: 87-88 at 2F and S: 85-86 and Q: 88-89 at 2E. Thus it will demodulate incorrectly if the corruption has caused the received symbol to move closer to another constellation point than the one transmitted. The green line indicates the direction of the satellite with respect to your location! Choose your location on the map; That's it! A coherent detector is able to independently demodulate these carriers. I have confirmed that my LNB is less sensitive for the verticals (approx 1.5 dB) so I’m now consider to turn it 90 degrees. The most common Symbol Rates used for British TV and radio are 22000 and 27500, BBC HD channels use an SR of 23000, while Sky HD tend to use 29500. for QPSK there are 2 bits per symbol so Es/No = Eb/No + 10.log).
