About
The SGR-Ligo is SSTL’s miniaturised Space GNSS (Global Navigation Satellite System) Receiver, built to the CubeSat PC-104 standard footprint. It is low mass, low power, and delivers position, velocity and time to Low Earth orbit satellites, using radiation tolerant core components and supporting dual antennas with 24+ channels capable of tracking GPS L1 signals, with options for GLONASS G1 and Galileo E1. It supports UART, CAN and I2C interfaces and can be powered from 3V3 or 5V spacecraft buses, including a passive-antenna low power mode.
