[Discuss-gnuradio] Getting signal from a LEO Satellite? ( Doppler shift handling)

Hi All,
I am planning to track a signal from a LEO Satellite which transmits approx. 100 kbps BPSK. 
I wonder which blocks should I use since the carrier offset ranges are:
around -50 kHz (beginning of the pass)
around +50 kHz (at the endof the pass)

Possible blocks are:

PLL Carrier Tracking
Costas Loop (using the frequency output port to get the carrier freq. error)
 
Any other suggestions- Examples?

Please don't offer manually shifting the frequency.(Using Gpredict)
