Calculate Transmission delay for the path using a satellite link
I am having a scenario as under.
I need to calcluate approx. minimum round trip for comunication where path used is a satellite link. consider the transmission in both direction is via geostationary satellite & travelling at spped of light(300,000Km/sec). to consider the transmission delay to transmit the data. |

ups.com... I am having a scenario as under. I need to calcluate approx. minimum round trip for comunication where path used is a satellite link. consider the transmission in both direction is via geostationary satellite & travelling at spped of light(300,000Km/sec). to consider the transmission delay to transmit the data. There are on-line calculators of satellite az/el/range parameters; a good one I use is: http://www.satcom.co.uk/article.asp?article=1 Once you have the range you can calculate delay to the precision required by using an appropriate value of c. However you can be lazy and use a more intricate calculator like; http://www.satellite-calculations.co...e/Downlink.htm which also calculates link delay. Note though that I'm not sure if it takes into account the satellite ephemeris and any diurnal variations. Depending on your application these may not be significant. If however you want to calculate satellite range from first principles you'd want to check out a text, such as "Satellite Communications" by Roddy (Prentice-Hall). The spherical trig required is delved into in more than adequate depth. Cheers. Ken |
