任务简介
准天顶卫星系统（QZSS）是一个由三颗卫星组成的区域时间传递系统，也是日本境内可接收的GPS星基增强系统。其主要目的是提高GPS在日本众多城市峡谷中的可用性，在这些地方只能看到极高仰角的卫星。次要功能是性能增强，提高GPS导航解的精度和可靠性。单颗卫星重约4000公斤，预期寿命15年，部署在椭圆、高倾角的地球同步轨道上。
原文
The Quasi-Zenith Satellite System (QZSS) is a three-satellite regional time transfer system and the satellite-based augmentation system for the GPS that would be receivable within Japan. The primary purpose of QZSS is to increase the availability of GPS in Japan's numerous urban canyons, where only satellites at very high elevation can be seen. A secondary function is performance enhancement, increasing the accuracy and reliability of GPS derived navigation solutions. A single satellite weighs about 4000 kg, has an expected lifetime of 15 years and is put in a elliptical, highly inclined geosynchronous orbit.
