C1 GNSS Receiver Board
The C1 family of OEM GNSS receiver boards is based on Bynav's advanced Alita ASIC, and provides high-precision heading and RTK positioning capabilities even under highly dynamic conditions. Covering all constellations, with eight-frequency or full-frequency options, the C1 range features both single- and dual-antenna models.
The lightweight, compact boards provide enhanced multipath mitigation, anti-interference and anti-blockage performance, and can be deeply coupled with an external INS (inertial navigation system). Communication options include serial, CAN and Ethernet, and an onboard TF card can be used to back up data.
