Lead Telecom System Engineer, MER (331)
Abstract
The MER Telecommunications System establishes communication between the spacecraft and the Deep Space Network at X band and various Mars orbiters at UHF. The X band communication system operates during all three mission phases: cruise, EDL (entry, descent and landing), and surface; the UHF communication system operates during EDL and on the surface. The communication links are used to support navigation requirements during the cruise phase and the surface phase. The key performance requirements and major telecommunications system engineering challenges faced in building these systems will be discussed and their final performance described. The Communications Behavior Manager software that configures both telecommunications systems for use will also be briefly described.
