The C/TT-510 Electra-lite Transceiver is flexible enough in its design to accommodate many mission scenarios where data links are required between two spacecraft. The unit can be configured in the factory for full-duplex or half-duplex operation. A unit configured for full-duplex operation with coherent transponding offers navigation capabilities like two-way Doppler ranging as well as the capability to be upgraded with future ranging algorithms. The bands are in-flight tunable in 56 kHz steps over 390-to-405 MHz for transmit and 435-to-450 MHz for receive. This is the reduced mass version of the C/TT-508 Electra Transceiver. This transceiver is ideal for lander missions with stringent mass and energy constraints. Electra-Lite maintains the core functionality, performance and reprogrammability of the standard Electra.
The Consultative Committee for Space Data Systems Proximity-1 Protocol incorporated in this transceiver provides error-free communication by employing an error detection and re-transmission service. Additionally, the Proximity-1 Protocol provides an automatic link establishment feature that allows the primary transceiver to reconfigure the secondary transceiver with no intervention from the secondary spacecraft.
