A lot of them calculate the POL angle for you as well. I'm guessing you didn't know that SatSig has one: http://www.satsig.net/ssazelm.htm//greg// Back to top « Last Edit: Feb 25th, 2008 at 5:09am by USN - Retired »   USN (Ret)   IP Logged

For those that don't, there are online and downloadable calculators that perform the calculations for you. We have one here at http://www.satsig.net/ssazelm.htm Others can be found with http://www.google.com/search?q=calculate+azimuth+elevation&sourceid=navclient-ff...//greg// Back to top USN (Ret)   IP Logged
