Abstract
(EN) A method for determining a state parameter of a global navigation satellite system receiver and an apparatus, in particular its absolute position, determining being based on- a measured information including a pseudorange, a carrier phase and/or a Doppler frequency measurement,- broadcast information on the satellite orbits and clock offsets, and- high accuracy correction information of a satellite positions, clock offsets, code and/or phase biases, the method comprising:-- determining a satellite position estimate and a clock offset estimate based on the broadcast information,-- determining a corrected satellite position and a corrected clock offset based on the satellite position estimate and the clock offset estimate by using the high accuracy information, in particular the high accuracy correction information of the satellite position and the clock offset.
