About
The GNSS-701 is a multi-constellation GNSS receiver from AAC SpaceQuest designed for CubeSat orbit determination. It receives GPS L1, GLONASS L1, and Galileo E1 signals to provide highly accurate position, velocity, and time (PVT) solutions. The receiver is qualified for LEO operations with radiation tolerance and provides outputs via RS-232 or I2C interfaces compatible with CubeSat OBCs.
