任务简介

QZSS（准天顶卫星系统）是日本的一个卫星导航系统，运行于倾斜椭圆地球同步轨道，旨在城市峡谷和山区实现最佳的高仰角可见性。该导航系统的目标是从三颗卫星组成的星座中广播与GPS互操作及增强信号，以及日本原创的QZSS信号。该导航系统的目标是从位于倾斜椭圆地球同步轨道的三颗卫星星座中广播与GPS互操作及增强信号，以及日本原创的QZSS信号。

原文

QZSS (Quasi Zenith Satellite System) is a Japanese satellite navigation system operating from inclined, elliptical geosynchronous orbits to achieve optimal high-elevation visibility in urban canyons and mountainous areas. The navigation system objective is to broadcast GPS-interoperable and augmentation signals as well as original Japanese (QZSS) signals from a three-spacecraft constellation.
