Abstract:

To address the demand for real-time observation in aerospace launch operations, a multi-format compatible telemetry image decoding device has been developed. The designed equipment simultaneously supports H264 and H265 decoding standards, capable of processing multi-source data including onboard telemetry data and satellite relay communications data, with quad-channel parallel image output capability. Through an innovative integrated architecture combining "industrial control computer, hardware decoding module, and system software", device miniaturization has been achieved while establishing a dual redundant decoding output mechanism, significantly enhancing system reliability. Detailed design principles of hardware architecture and implementation schemes of software algorithms are systematically elaborated. Field verification on launch vehicles demonstrates that the equipment effectively realizes real-time parsing and image reconstruction of multi-format telemetry data, meeting the stringent technical requirements of aerospace engineering for high-reliability real-time monitoring. This solution demonstrates significant engineering application value in launch vehicle systems.
