I. Product Introduction Telemetry and remote control systems are an indispensable and important technical means in China's national defense and economic construction. They are mainly used for long-distance telemetry information acquisition, processing, and control. For example, during the satellite development phase, telemetry and remote control systems are used to acquire the operating parameters and environmental data of various onboard systems during satellite ground tests, providing a basis for verifying satellite performance and analyzing faults. During the satellite's operational phase, telemetry and remote control methods are needed to receive telemetry data transmitted from the satellite and control its operational status. The PXI bus telemetry and remote control series modules, while drawing on the essence of traditional telemetry and remote control technologies, adopt standardization, modularization, and serialization as their main design principles. They organically combine telemetry and remote control technologies with PXI bus technology, possessing highly flexible reconfigurability. This allows the system to select and rationally configure various telemetry and remote control functional modules according to the specific characteristics of the mission, making the telemetry and remote control system more concise and refined. The miniaturization and portability of the PXI telemetry and remote control system further expands its application scope. The PXI bus telemetry and remote control system is suitable for various applications involving small stations, mobile stations, and small unmanned aerial vehicle (UAV) telemetry and control systems for small satellites. Figure 1 is a schematic diagram of the PXI bus telemetry and remote control system (taking the PCM-PSK system as an example).

Integrated Management Software The PXI bus telemetry and remote control integrated platform integrated management software is mainly used to: set parameters and display status of system hardware devices; perform closed-loop self-test judgment of the telemetry and remote control system; perform accurate processing of telemetry data, and perform display and storage functions. The PXI bus new telemetry and remote control integrated platform integrated management software can be mainly divided into two parts according to function: integrated monitoring software and data processing software. Figure 2 and Figure 3 are the main interface of the system integrated management software and the telemetry data processing interface, respectively.
