Abstract
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.
