Abstract

Abstract: In order to obtain high-precision aircraft position, the handheld GNSS receiver is taken on the aircraft, satellite data is received during the flight of the aircraft, and the GNSS data received by the receiver is subjected to difference using NRTK-PPK system. Since the handheld GNSS receiver is placed next to the window of the passenger aircraft, it can only receive the satellite data of the half-day sky. It needs to optimize the PPK algorithm and compare it with the ground RTK difference result to achieve the decimeter-level high-precision positioning effect.

Key words: aircraft position, NRTK-PPK, multi-constellation, handheld GNSS receiver, RTK difference
