The combination of code and carrier phase measurements can improve the precision of the pseudorange and the positioning performance of the receivers.

Web29 Sep 2024 · Some GPS receivers use a phase lock loop to lock onto a signal from a GPS satellite, others use a frequency lock loop, and yet others use a hybrid of the two. Phase lock loops and frequency lock loops are the two of leading contenders for locking onto a signal whose frequency changes slightly due to changes in the incoming signal and due to using … Web18 Aug 2014 · If it were possible imagine a tape measure stretched out between the two antennas, this measurement is the true range. Pseudorange is the range that a GNSS receiver measures between the transmit antenna on the SV and its' receive antenna. It differs from the true range due to many physical effects.

Web8 Nov 2008 · where the pseudorange measurements, ρ, are provided in meters.We shall refer to this measurement of TEC as absolute code-derived TEC. Similarly, GPS carrier phase can be used to derive TEC, because the phase of the radio wave advances during propagation through a plasma by an equivalent distance as the group velocity is retarded.
