The C/TT-510 Electra-Lite Transceiver is built to accommodate many spacecraft data link scenarios. The C/TT-510 is factory configurable for full-duplex or half-duplex operation. In full-duplex operation with coherent transponding the C/TT-510 offers two-way Doppler ranging and upgradeability for 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. With reduced mass over the C/TT-508 Electra Transceiver, the Electra-Lite is ideal for lander missions with stringent mass and energy constraints. Electra-Lite maintains the core functionality, performance and reprogrammability of the standard Electra.
