摘要: 为了获取高精度的客机位置数据,本文将手持GNSS接收机带上客机,在飞机飞行过程中接收卫星数据,然后利用专用网络事后差分系统对接收到的GNSS数据进行事后差分。由于手持GNSS接收机放置在客机玄窗旁,只能接收到半边天的卫星数据,因此需要对事后差分算法进行优化。将优化后的结果与地面RTK差分结果进行比较结果表明:利用本文算法可以达到分米级高精度定位的效果。

关键词: 客机位置, 网络事后差分, 多星座, 手持GNSS接收机, RTK差分

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
