What is code phase vs carrier phase?
Carrier phase- GPS measurements based on the L1 or L2 carrier signal. Carrier- A signal that can be varied from a known reference by modulation. Code phase GPS- GPS measurements based on the pseudo random code (C/A or P) as opposed to the carrier of that code.
What is carrier phase in GNSS?
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 carrier phase?
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.
What is the difference between pseudorange and carrier phase?
In Global Navigation Satellite System (GNSS) community, pseudorange observables, without integer ambiguity, have large measurement noise, while carrier phase observables, with high measurement accuracy, have integer ambiguity, which restricts the direct use either of them for high-accuracy navigation and positioning.
