The invention provides a satellite-borne telemetry and telecontrol communication integrated terminal system, which comprises an FPGA (Field Programmable Gate Array) circuit, an RS422 transmitting circuit, an RS422 receiving circuit, a multichannel AD (Analog to Digital) parallel conversion circuit and a multichannel instruction reverse driving circuit, and has the functions of simulating telemetry acquisition and expanding the number of telecontrol instruction driving paths. Data transmission adopts a spatial data packet format; any RS422 receiving channel can receive a spatial data packet, carry out legality check according to the format requirement of the data packet, and carry out addressing according to a packet auxiliary guide head. According to the invention, integrated design and omnidirectional cross interconnection bridging of simulation telemetering acquisition, remote control instruction driving and RS422 serial communication functions are realized, and satellite telemetering data sharing and remot
