摘要

a - gnss终端OTA (over - air)测试系统是对支持a - gnss的终端进行OTA性能测试的系统。支持A-GNSS的终端可以比只支持GNSS的终端更快地搜索到卫星导航信号。主动测试是在微波消声室中测量终端在空中的辐射功率和接收灵敏度，可以明显地显示整个终端的辐射性能。已经发布了很多OTA的测试计划，其中最受认可的是CITA发布的测试计划。乐器主要由思博伦和R&S公司提供。介绍了网络运营商和测试机构的测试计划、测试情况，比较了Spirit和R&S提供的两种解决方案，描述了测试过程，模拟了灵敏度测试过程。

Study on A-GNSS Terminal Over-The-Air Test System

The A-GNSS terminal Over-The-Air (OTA) test system is a system for OTA performance of terminals that support A-GNSS. Terminals supporting A-GNSS can search for satellite navigation signals quicker than terminals only supporting GNSS. Active test is to measure the radiant power and receiving sensitivity of terminal over the air in a microwave anechoic chamber, which displays radiation performance of whole terminal obviously. Many test plans for OTA have been released, and among them the most recognized one is released by CITA. The instruments are mainly provided by Spirent and R&S. This paper introduces test plans, test situation of network operators and test institutions, compares 2 solutions provided by Spirit and R&S, describes test procedures, and simulates sensitivity test process.
