SATELLITE TELECOMMAND MODEM

Shreyas M, V. Sambasiva Rao

Abstract: With the increasing interest in nano, micro and small satellites, need arises for miniaturization of satellite systems for small size, low weight, low cost designs and short development periods. For the operation and maintenance of a satellite in the designated orbit, a reliable commanding system is mandatory. This paper presents the work carried out in designing and developing a telecommand modem for use with student satellites. To transmit low bit rate command data, PSK/PM a two level modulation scheme is adopted. The architecture and the simulation and test results of the hardware realized on an FPGA are provided.

Keywords: Phase Shift Keying, Phase Modulation, PSK/PM Modem, bit error rate, satellite commanding.
