Hi my friends,
I'm afraid I'm wrong, but it seems to me that the catalog number,
therefore the tle of Zhuhai-1 1 (CAS-4A) and Zhuhai-1 2 (CAS-4B) are
maybe inverted.
Listening the CW beacon, the Doppler shift correction with fresh tle
for Zhuhai-1 2 (CAS-4B) seems correct, but for his brother nr 1
(CAS-4A), it looks like the bird is a bit ahead the prediction : at the
beginning of the pass we have to decrease manually the frequency to
chase the bird, at about the half of the pass it's the opposite, we have
to hold a little bit the frequency shift correction.
No ?
Have a nice day all !
