Spacecraft Communications

Mission Experience

L3Harris has a vast and diverse history in spacecraft communications. For 20 years, every U.S. Mars rover and orbiting spacecraft mission have used L3Harris transceivers - including the Electra-Lite and Electra on both the current Perseverance lander and orbiting spacecraft respectively. L3Harris also provides the radio for NASA’s Common Communications for Visiting Vehicles (C2V2) program for the ISS. C2V2 is a program designed to provide standardized communications between the ISS and docking vehicles. The system is secure and provides reliable communications with commercial crew and other visiting vehicles. It is available for all phases of rendezvous, docking and mated operations.
