Design of Xilinx based Telemetry System using Verilog

Telemetry is a technology that allows the remote measurement and reporting of information of interest to the system designer or operator. The transmission media may be air and space for satellite applications and copper wire and fiber cables for static ground environments like power generation plants. A sure and effective telemetry link system plays a vital role in controlling and commanding the aircraft or satellite. The telemetry, tracking and command (TT and C) system of a spacecraft provides the most vital telecommunication link between a satellite and ground station. The TT and C systems provide the uplink for command and downlink for monitoring the various health parameters through telemetry and much needed tracking information for the satellite for monitoring its position in the orbit.The link is provided using a ground station and onboard telecomm and & tracking data receiving system onboard decoder and telemetry transmitter. The TT and C link of a satellite is of prime importance, right from the time of its launch to the end of the mission. In this paper, telemetry system is developed to communicate data that identified in the objects characterization or parameters which give a clear idea to analyze the moving objects in real time and space which is an important characterization in day to day life. The aim of the paper is to design a telemetry system in VERILOG and successfully simulated it through XILINX. By this, an effective link using digital techniques is developed. The digital techniques used in design makes the FSK modulator and demodulator sections to be flexible in modifying the frequencies and other parameters. By the features of XILINX the code was generated successfully and simulation results can be dumped into an FPGA. Thus results a practical telemetry system. By using more advanced techniques we can design a telemetry system which can be more reliable and accurate in transmission.
