103 - ATPL Question Bank in English - In an unconstrained three-dimensional GPS solution with unknown receiver clock bias, how is that bias normally determined?

Question 103 - Radio Navigation - ATPL - Airline Transport Pilot Licence

It is assumed to be exactly zero in every receiver.

It cannot be estimated or corrected.

It is estimated together with position using at least four independent satellite pseudoranges with suitable geometry.

The receiver clock must first be physically synchronised exactly to the satellite clocks before a position solution can be calculated.
