The KL-Beta A and B satellites are test satellites for a global multimedia satellite system for the German company KLEO Connect.
The satellites are improved versions of the earlier KL-Alpha prototypes.
The purpose of the Beta phase test satellites is to assess the Ka-band mobile communication environment adaptability, the verification of a Ka-band LEO satellites to GEO satellite interference suppression technology, and the orbital evaluation of commercial-grade electronic components to achieve low-cost long-life. They were developed by the Institute of Microsatellite Innovation of the Chinese Academy of Sciences. They are equipped with laser communication payloads, Ka-band communication payloads, and Hall electric thrusters to carry out high-speed inter-satellite laser communications and multi-beam communications.
The satellites were launched in August 2021 on a CZ-6 rocket from Taiyuan.
