New function of GTS - Tiantong No. 1 terminal OTA automated test

In recent years, satellite communications have received widespread attention. The TianTong -1 statellite mobile communication system is a statellite mobile communication syatem independently developed and constructes by China.It consists of a space segment,a ground segment and user terminals.TheTianTong-1 satellite mobile communication system is a high-orbit satellite,which puts forward higher requments for antennas,signal transmission losses and power transmission.

In order to ensure that user terminals achieve good communication services, OTA performance testing is crucial. As a result, Universal Test upgraded the Tiantong No. 1 terminal OTA automated testing solution based on the original star product RayZone® 2800.

RayZone® 2800 is an All-in-One OTA test system for 5G terminals (Sub-6GHz).It fully meets the Passive,SISO,and MIMO test requirements for 5G terminal development. It only takes 40 minutes to complete the MIMO OTA test.

In addition, RayZone® 2800 also supports various common communication standards, including 2G/3G/4G/5G SISO/MIMO, Wi-Fi, GNSS and IoT communication standard NB-IoT/eMTC testing.

The upgraded OTA automated test system is compatible with Tiantong No. 1 testing mainstream instruments Zhongke Jingshang 

JY3000T and Galaxy Highlight SP3610.

This test refers to the China Telecom enterprise standard "China Telecom Mobile Terminal Requirements White Paper-Volkswagen Intelligent Tiantong Dual Card Slot Handheld Terminal Volume (2023v1)", which supports the output of the maximum EIPR and minimum EIS. The dynamic range meets the limit requirements of the Tiantong No. 1 test standard "China Telecom Mobile Terminal Requirements White Paper - Volkswagen Intelligent Tiantong Dual Card Slot Handheld Terminal Volume (2023v1)". The uplink power test can reach more than 43dBm, and the downlink sensitivity test can reach - Below 143dBm.

In addition, the accuracy of the system can be effectively guaranteed. After verification by conduction and calibration antennas, the TRP fluctuation range is less than 0.5dB, and the TIS fluctuation range is less than 0.8dB. System stability <0.5dB, within one week.

This test project fills the gap in OTA automated testing of Tiantong No. 1 terminal and provides a strong guarantee for the OTA testing of Tiantong No. 1 terminal.

GTS will continue to work hard in the field of satellite mobile communication testing to maintain continued competitiveness, ensure good competitive advantages, and provide customers with valuable services!
