Proximity-1 Space Link Protocol
From Handwiki - Reading time: 2 minProximity-1 Space Link Protocol is a short haul delivery communications 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 in the 70-centimeter band so as to reduce complexity of the ground craft, using these frequencies:
- 437.1000 MHz
- 440.7425 MHz
- 444.3850 MHz
- 448.0275 MHz
However, using this protocol over the standard CCSDS frequency bands is perfectly acceptable if the UHF allocation is not usable.
