Embodiment Construction
[0027] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0028] Satellite navigation carrier phase high-precision positioning usually adopts the station-satellite double-difference method, and its linearized carrier-phase double-difference observation equation formula can generally be expressed as formula (2.1):
[0029]
[0030] Among them, u corresponds to the user receiver, c corresponds to the reference station, k corresponds to the reference star, i corresponds to the non-reference star, δx u ,δy u ,δz u Refers to the error correction number of the user's three-dimensional position coordinates, is the double-differenced carrier phase observation, is the integer ambiguity, λ is the carrier phase wavelength (where the wavelength can be the GNSS carrier wavelength, or its ultra-wide-lane, wide-lane combined carrier wavelength), is the double-difference distance from the user to the satellite calculat...
