Carrier phase measurements

A: Simply put, the carrier phase measurement is a measure of the range between a satellite and receiver expressed in units of cycles of the carrier frequency.

Why is carrier phase measurement more accurate?

Carrier phase is another processing technique that gathers data via a carrier phase receiver, which uses the radio signal (aka carrier signal) to calculate positions. The carrier signal, which has a much higher frequency than the pseudo-random code, is more accurate than using the pseudo-random code alone.

What is carrier phase GPS?

Carrier phase tracking is a highly accurate means of positioning used in GNSS surveying applications. The product of the period of the carrier frequency times the speed of light gives the wavelength, which is about 1900mm for the GPS L1 carrier.

What is the precision of the carrier phase?

As shown in Fig. 4-a, the carrier-phase method can achieve a sub-15 cm and sub-10 cm overall 3D positioning accuracy for 90% and 80% of UEs, respectively.

What is carrier phase shift?

The carrier phase shifted pulse width modulation carrier is a triangular wave, the phase shift angle of the triangle wave is related to the submodule position in the converter bridge arm.
