[amsat-bb] SatPC32 Rig Tracking Question

[Rick Walter]

Hi Brian. You may already do this but:
Is your computer clock right on? I have a simple program running that goes out often and checks my computer clock against a time standard and resets the computer clock to the correct time. Another important items is are you using relatively recent Keplerian elements? With some birds, week old keps can make a difference. I am a member of AMSAT and appreciate everything they do for us. However, sometimes the Keps on AMSAT are a week old. I download them from CelesTrack with Space Trak TLE Retriever,  they may be hours old. Finally with the low, high drag orbit of the ISS you can be off by minutes when they boost it’s orbit once in awhile. 
73,
