Description

M21 Deeply coupled IMU All-constellation Multi-frequency High Precision RTK GNSS receiver.

M21 is Bynav new-generation proprietary high-precision RTK positioning module based on the Alice 22nm high performance automotive SoC, designed on the basis of ISO26262 ASIL B functional safety. The module supports GPS L1C/A/L1C/L2/L5, BDS B1l/B2l/B3l/B1C/B2a/B2b, GLONASS G1/G2, Galileo E1/E5a/E5b/E6, QZSS L1/L2/L5/L6(CLAS), NavIC L5, SBAS L1C/A and L-band. The built-in anti-interference and anti-deception technologies enhances RTK calculation on multiple modes and frequencies, which significantly improves RTK initialization time, measurement accuracy and reliability in complex environments such as satellite signal interference and loss. Relying on the excellent performance, M21 is well suited for autonomous driving, lane-level navigation, drones and robots.
