L1/L2/L5 Helical Antenna

Bynav helical antenna is equipped with the high-precision positioning module M20, supporting L1, L2,L5, and possesses the characteristics of being compact and precise.

The M20 is a high-performance NRTK/PPP/PPP-RTK GNSS positioning module based on Bynav's state-of-the-art automotive-grade Alice SoC. The low-SWaP (size, weight and power) module is designed to deal with challenging operating conditions such as signal interference and outages and urban canyons.

The full-constellation, full-frequency GNSS module supports L-band and CLAS corrections and includes excellent anti-interference and anti-jamming capabilities. The M20 is ASIL B-rated and is ideal for self-driving vehicles, ADAS, mapping and surveying drones, and other robotics applications.

The M20 GNSS receiver module is available in a dual-antenna variant for high-precision attitude determination.
