The Kaanshou was a military satellite launched by the Chinese Intelligence Bureau to monitor international radio frequencies. However, given its rudimentary abilities it is only capable of receiving, saving, and re-transmitting radio data on the public airwaves; or on otherwise publicly available frequencies. The satellite also can not be re-modified to utilize secured transmissions and it can only record radio information for brief periods before passing out of range. Just as well the Chinese can only receive the stored data during brief windows when it's tracking over head.
Despite its setbacks as a piece of hardware it was technical proof that space could be used as a front for intelligence gathering in the future. It also expanded the proof needed for launching high-weight objects to higher altitudes, which was useful in the Gāo Hǎibá Hōngzhàjī projects. The project also expanded on the concepts of the OARP missions.
