Hi Does anyone in the group know the max limits for Doppler tracking in the currently available software packages? I'm aware that L band from LEO is fairly comfortable, but how about tracking higher frequencies ? I suppose the limiting factor could be the update rate....If the software cannot keep up with a rate determined bythe rate of change of doppler compared to the bandwidth of the transmission.......then the satellite cannot be tracked successfully. 145MHz +/- 3.5kHz ish10.45G +/- 250kHz ish
Fortunately, it gets easier with light...........
Many thanks David
