Compute hardware: Satellite-computing module and satellite-network security module BUPT-4 / TY49 spacecraft. University launch account identifies these modules and a small remote-sensing camera. Processor models, memory and computing throughput are not specified. Launch telemetry is not a sustained compute benchmark. The university-authored July 23 launch account on Beijing Daily's author platform confirms the same modules and camera at https://peking.bjd.com.cn/content/s6a622584e4b0e45f3fd517fc.html. official launch hardware description.

Technical specifications retain the source’s original units and evidence status. Hardware counts, compute rates and power are not equivalent; launched hardware does not establish demonstrated performance. Supplier counts include suppliers and hosts only, reflect current filters and cover this directory, not the entire market. “No record” means no disclosure captured; it does not mean the work is unawarded. Latest developments use source dates, not routine review or collection dates.
