POSITIONING METHOD AND DEVICE FOR PRECISE POINT POSITIONING/REAL-TIME KINEMATICS (PPP-RTK) Russian patent published in 2021 - IPC G01S19/44 

Abstract RU 2759392 C1

FIELD: satellite navigation.

SUBSTANCE: invention relates to satellite navigation. To attain the goal, the initial observation data is determined when a direct signal is detected transmitted by a multi-system navigation satellite and a LEO grouping; the information of the differential correction of the navigation satellite transmitted by the LEO grouping is received, as well as the exact orbit and the exact shift of the LEO satellite clock; high-precision positioning using the information of the differential correction of the navigation satellite, the exact orbit and the exact shift of the LEO satellite clock and the initial observation data is performed, or high-precision positioning with ground differential correction using the information of the differential correction of the navigation satellite, the exact orbit and the exact shift of the LEO satellite clock, initial observation data and complex information of error correction of ground differential correction when receiving complex information of error correction of ground differential correction.

EFFECT: increase in positioning accuracy.
