Abstract: Aiming at the issues of unexpected data in the downlinked data because of the random low voltage differential signaling (LVDS) generated by the interface circuit during the frequent power-on and power-off initialization process of the payloads of the new generation ocean color observation satellite, as well as frequent manual maintenance and management of storage capacity on the ground due to the continuous storage of solid-state memory, a data buffer management strategy was designed. A buffer control scheme was proposed, involving six control commands linked with a state machine working in different operational modes. The three-line timing of the payload's LVDS power-on interface was tested and analyzed, and a payload buffer control model based on different on-orbit telemetry modes of the satellite was established. An autonomous erasure design for solid-state memory was conducted, and a cyclic storage autonomous erasure architecture based on capacity threshold judgment was constructed. By analyzing the read/write rate of the payload data, a method for autonomous erasure during cyclic rewriting in solid-state memory was proposed. Test results show that the buffer control technology can completely eliminate spurious unexpected data, making the availability rate of the first frame of telemetry data reach 100%. The proposed strategy and design fully release the storage resources of the solid-state memory, improve the hardware data storage efficiency, and achieve zero maintenance of the on-orbit storage area while effectively preventing data overflow.
