How Sun Outage looks like on the Spectrum Analyser

https://www.satellite-calculations.com/Satellite/sunoutagestatus.php?11.95/1/meter/70/35/0.1/0.8/lin/6/4/2/followthesun/nodynlis/0dB/notCNbased/10/3/bigmap/0.00/0.2/0.1
Is a very nice website to help you with the sun outage view worldwide at any given time.



They also created a tool which makes it easier to configure satellites of interest. https://www.satellite-calculations.com/Satellite/sunoutagestatusconfigurator.php
It will open an URL where all the parameters are part of the URL. This URL can be bookmarked or shared.
At the moment it is preconfigured for 10 second refresh, 1m (40inch) antenna, Ku-band and with affected area is based on where the Sun is inside the receiving antenna 3dB beam width.



It is also possible to select only the satellites that are relevant for you.

1. Go to the https://www.satellite-calculations.com/Satellite/sunoutagestatus.php
2. Tick the "Plot selected satellites" tick-box 3. Select satellites relevant to you want by using CTRL+click (multiple list selections) 4. After the satellites is selected you can click on auto update "10s" button.
5. Click the button "Click for big map" in the top left corner if you want a bigger map 6. You can also click the "URL link with settings" for URL which contains your selected satellites (can be bookmarked for recall later).



You also have https://www.satcomresources.com/sunOutage is that helps.

Attached is a video to show what you see on the spectrum analyser. Basically the sun is a giant transmitter (from 0 Hz to eternity) so your downlink is swamped with noise. This is why in the video you see the carrier remains but the noise (only seen left and right) increases until you lose lock. It comes by itself and goes away by itself.
The smaller the antenna the longer the sun outage (because the openings angles is larger). The larger the antenna the shorter (because the openings angles is smaller).

Symbol rate, Bandwidth and Bit rate Calculation

-
In satellite communication bandwidth (BW), symbol rate and bit rate are the most vital fact for proper signal transmission. There are many commercial software for BW, Symbol rate and bit rate calculation for TV signal transmission. But the equations of these parameter calculation are as follows. BW= (1+Roll of factor)* Symbol rate In general Roll of factor is 35% Symbol Rate =BW / (1+Roll of factor) and Bit Rate = Symbol rate * Modulation* FEC* (188/204)                                     [when 188 is encoder packet length] or Bit Rate = Symbol rate * Modulation* FEC* (204/188)                                     [when 204 is encoder packet length] Here, FEC = Forward Error Correction. In general FEC is in the range from 1/2 to 7/8. 188/204 = constant Unit ** BW= Hz, KHz, MHz, GHZ ** Symbol Rate= sps or baud, Ksps or Kbaud, Msps or Mbaud, Gsps or Gbaud ** Bit Rate= bps, Kbps, Mbps, Gbps Baud: U nit of signalling speed Baud rate: N umber of symbols transm

Terminology: EIRP, G/T, Input Back-Off, Output Back-Off

-
  EIRP:   Used to indicate the power transmitted from an antenna. EIRP=Power +Antenna Gain, Both EIRP and Power is expressed in dBW and Gain in dBi. G/T:   It is the figure of merit for an earth station and is expressed as dB/K (dB per K). G/T= Antenna Gain-10*Log (System Noise Temperature) The higher the better-G/T can be raised by using a higher gain antenna or a lower temperature LNA. The earth station G/T determines the received carrier to noise ration. Increasing station G/T will increase the C/N of the received carrier. Input Back-Off (IPBO):   The level of a signal at the input of an amplifier relative to that level at the input that would result in the maximum possible output level. For example, if an input level of -20dBm causes max output and the actual input level is -25dBm, the IPBO is 5dB. Both IPBO and OPBO are commonly used to determine the operating levels in a satellite transponder TWTA. Output Back-Off (OPBO)   The level of a signal at the output

Bit Error Rate (BER) and Roll Off Factor

Roll Off  Factor W hen a digital signal is modulated the output would be a waveform with the shape of sin(x)/x. Now this has an infinite bandwidth. So in order to be able to transmit this signal over satellite we need to filter it to reduce the occupied bandwidth. This is done by applying a "raised cosine roll-off filter". This filter is present both at the modulator output stage and at the input of the demodulator (I believe one says these filters are then matched). The steepness and the resulting occupied bandwidth can be set by the parameter roll-off factor. In DVB-S2 it can be 0.20 (20%); 0.25 (25%) or 0.35 (35%) where the  Occupied bandwidth = symbol rate x (1 + roll-off factor). Figure: Occupied bandwidth, Roll off factor and symbol rate
