Abstract	This paper investigates the implementation of power control techniques for crosslinks communications during a rendezvous scenario of the crew exploration vehicle (CEV) and the lunar surface access module (LSAM). During the rendezvous, NASA requires that the CEV supports two communication links: space-to-ground and crosslink simultaneously. The crosslink will generate excess interference to the space-to-ground link as the distances between the two vehicles decreases, if the output power is fixed and optimized for the worst-case link analysis at the maximum distance range. As a result, power control is required to maintain the optimal power level for the crosslink without interfering with the space-to-ground link. A proof-of-concept will be described and implemented within Goddard Space Flight Center (GSFC) Communications, Standard, and Technology Lab (CSTL).
