L3Harris Technologies, a trusted disruptor for the global aerospace and defense industry, delivering solutions connecting the space, air, land, sea, and cyber domains has introduced a new S-band Multimode Transponder for satellite communication applications.
The C/TT-520 from L3Harris is an S-Band multimode transponder that provides full-duplex communications with a variety of NASA networks and protocols. It leverages the latest available technologies, traditionally tested and screened in accordance with EEE Level 2 parts program methods.
The C/TT-520 is ideally suited to the harsh realities of space communications. It features receive data rates from 125 bps to 3 Mbps and transmit rates up to 6 Mbps. It maximizes throughput while maintaining a noise figure of 2.5 dB and implementation loss of 1.5 dB – assuring robust link closure under even the most marginal of conditions.
The C/TT-520 provides accurate ranging using both Tracking and Data Relay Satellite System (TDRSS) long code pseudo-random noise (PN) ranging and Doppler turnaround ranging. PN ranging meets the stringent requirements of the TDRSS Space Network.
Compatible systems include the TDRSS, Space Network, the NASA Ground Network, the NASA Deep Space Network, and the Universal Space Network. The C/TT-520 also supports the Common Communications for Visiting Vehicles protocol used on the International Space Station and is a flexible hardware and firmware solution adaptable to a variety of missions and applications.
The C/TT-520 is configurable to suit mission and spacecraft buses. Selectable parameters include RF frequency, 1 of 85 gold codes, receive and transmit data rates, receive and transmit modulations, RF output power, encryption/decryption, convolutional encoding, Viterbi decoding, and Reed Solomon encoding/decoding. Available interfacing includes RS-422, low-voltage differential signaling, universal asynchronous receiver transmitter, and SPI.
