The Design and Application of C-band Base Station Based Multi-target Telemetry Network System

Abstract

A C-band base station based multi-target telemetry network system for flight test is designed in this paper. The requirements of multi-target transmission are realized by TDMA and TDD technology. And the transmission rate of up to 50 Mbps is provided by the high efficient modulation method. An integrated air-to-ground telemetry network is built with C-band wireless two-way link. The telemetry signals of super large airspace are covered seamlessly through multiple base stations, therefore the shortage of current telemetry is solved, and the demand of multi-target and mass date transmission for flight test is satisfied. The development of the system provides technical support for the high speed data transmission of the flight test, which will lay a foundation for the construction of integrated air-to-ground test and the test network system.
