Bynav is a leading specialist developer of high-precision GNSS and GPS RTK positioning and navigation solutions for unmanned systems.

High-Precision GNSS Receivers

Our products are ideal for demanding unmanned and autonomous applications on land, at sea and in the air, and have been used globally in a wide range of UAVs (unmanned aerial vehicles), UGVs (unmanned ground vehicles) and USVs (unmanned surface vessels).

With an expert, ISO9001-certified, in-house R&D capability, we have developed a number of core proprietary technical capabilities, including integrated navigation algorithms, baseband signal processing and SoCs (systems on chip).

RTK GNSS OEM Receiver Boards

The C1 family of OEM GPS and GNSS receiver boards provides high-precision heading and RTK positioning capabilities. Covering all constellations, with eight-frequency or full-frequency options, the C1 range features both single- and dual-antenna models.C1 GNSS Receiver Boards

The lightweight, compact boards provide enhanced multipath mitigation, anti-interference and anti-blockage performance, and can be deeply coupled with an inertial navigation system. Communication options include serial, CAN and Ethernet.

C1-8S OEM RTK GNSS Receiver Board

The C1-8S is a single-antenna OEM RTK GNSS board that supports eight different frequencies across all GNSS constellations. Measuring just 46mm x 71mm, the compact board is ideal for a wide range of UAV and autonomous vehicle applications including mapping, surveying and precision agriculture.

With RTK capabilities for centimeter-level accuracy, the C1-8S delivers high-reliability continuous positioning, heading, velocity, and timing data. The board can be connected to an external IMU to form a navigation solution that operates even in GNSS-denied conditions.
