Module proximity1 

Proximity-1 physical layer parameters (CCSDS 211.1-B-4). Proximity-1 Physical Layer parameters (CCSDS 211.1-B-4).

Defines the RF and modulation parameters for Proximity-1 space links. These are short-range, bidirectional links used between landers, rovers, orbiters, and CubeSat formations.

Modulation: GMSK with BT = 0.25. Band: UHF 390-450 MHz. Data rates: 8 kbps to 256 kbps (powers of 2).
