Hi folks,

Rather than trying to compare apples and oranges between various satellite tracking programs and their perceived satellite tracking inaccuracies, I ran SatPC32, HRD V.:6.5.0.184 and SRDConsole V.3.0.4 simultaneously on the same machine with the same internal clock and exact matched home location incl antenna height, same Kepler data etc.The results can be seen on the attached image (for those that receive this email directly). All three programs and are matching each other in terms of satellite position relative to location. Any significant discrepancies between programs that users might experience are most likely attributable to differences in program setup and not a result of program bugs as indicated lately in messages.

For those reading this message on the BB, I will post the image on the AMSAT Facebook page.

Hope this helps,

Stefan, VE4NSA

Mike, I don't see any times listed for the Amsat tracking. I think the problem is people are saying that HRD "lags" (ie, the track is correct, but several seconds/minutes behind). Regardless of if that is true or not, what I would suggest to verify HRD's tracking is to open two windows, one with AO-91 or 92 in HRD (realtime, during an actual pass), and one with Amsat Argentina's website:

http://amsat.org.ar/pass.htm

Be sure to enter your correct grid square and select the correct satellite, and it will tell you current Az/El and doppler frequencies for Uplink and Downlink. I've found this site to be very reliable, and no installs are required (it runs in the browser).

next. On another note, I've been comparing satellite passes between HRD Satellite Tracking and AMSAT's tracking and I am unable to find any differences. Here's an example with AO-91: http://www.hamradiodeluxe.com/AO-91-Pass-min.png
