Proximity-1 Space Link Protocol is a short haul delivery protocol designed to establish a two-way communications link between a lander and an orbiter, negotiate data rate and communications mode, and reliably deliver data during short orbiter-to-surface contacts.

Developed by Consultative Committee for Space Data Systems and documented in a number of CCSDS Recommendations [1] [2] [3]

Proximity-1 is implemented on Mars Exploration Rovers, Mars Odyssey, Mars Reconnaissance Orbiter, Mars Express [4] as well as on Phoenix Mars Lander [5]

The frequency band used by this protocol is typically 200 mhz - 400 mhz so as to reduce complexity of the ground craft. However, using this protocol over the standard CCSDS frequency bands is perfectly acceptable.
