I use Nova for Windows (PC software)
for tracking of space satellites (as well as ISS and Shuttle, when in orbit). #Updated Keperian elements are requried for precise AOS/LOS (Acquisition and Loss of signal) at you local QTH / operational location.
Nova does not yet work with MS Vista OS, works fine with WinXP
AO-51 will make a nice 8 minute South to North pass over Midwest (near Chicago) at 9:30 PM CDT tonight (Friday).
We keep moving forward, opening new doors, and doing new things, because we're curious and curiosity keeps leading us down new paths. -- Walt Disney
