GLsun Optical Switches Used on Multimedia Satellites

Published: 2021-08-11

China successfully sent two multimedia Beta phase test satellites into pre-set orbit from Taiyuan Satellite Launch Center in north China's Shanxi Province.The KL-Beta A and B test satellites were launched by a Long March 6 (CZ-6) carrier rocket at 7:01 p.m., August 4, 2021 (Beijing Time). The launch mission was a complete success.

 

 

The satellites were developed by the Innovation Academy for Microsatellites of the Chinese Academy of Sciences (IAMCAS). They are equipped with laser communication payloads, Ka-band communication payloads and Hall-effect thrusters, to carry out the test and verification of key technologies and scenario-based demonstrations such as high-speed interplanetary laser payloads, multi-beam digital payloads and electric propulsion system.

 

It was the 382nd flight mission for the Long March series carrier rockets, the 73rd and 74th satellites by IAMCAS, as well as a glorious moment for Guilin GLsun! Our mini 1xN mechanical optical switches were selected and used by IAMCAS to help complete the mission, after undergoing a series of strict screening and testing, including complex debugging process, ground testing and final validation test. It also marked the very first time for China-made mini mechanical optical switches being used in aerospace.
