\
The SATE NAVSATE DroneCAN GPS features a u-blox GPS module, ISentek compass, and tri-colored LED indicator for intuitive status monitoring. It employs the DroneCAN protocol for communication, providing superior resilience against electromagnetic interference compared to traditional serial connections, thereby enhancing overall system reliability.

This design eliminates the need for dedicated serial ports on the flight controller, while enabling seamless integration of multiple CAN devices on a single bus through a CAN splitter board—ideal for scalable, multi-sensor drone configurations.
