Q1:

For obtaining accurate distance of the satellite

A the GPS receiver slides its codes backwards until it synchronises with the satellite signals

B the signal arrival time is corrected for tropospheric and ionospheric delays

C the carrier phase measurement technique is adopted

D All of these

ANS:C - the carrier phase measurement technique is adopted

I think option D is correct because accurate range measurement is done by correcting atmospheric delays too.
