DUAL-BAND GNSS
TAU824M-N200 GNSS Module
TAU824M-N200 is a GNSS dual-band high-precision navigation and positioning module based on the CYNOSURE IV-E GNSS SoC. It tracks all global civil navigation systems (BDS, GPS, GLONASS, Galileo, QZSS, NavIC and SBAS) in L1 and L5 bands, including BDS-3 signals. The Cynosure architecture achieves higher sensitivity, improved jamming resistance and multipath mitigation, providing highly robust service in complicated environments — ideal for vehicle monitoring and navigation applications.

Frequently Asked Questions
Common questions about TAU824M-N200 functionality and typical use cases.
TAU824M-N200 achieves 1.0 m CEP position accuracy in open-sky dual-band positioning, and better than 1.0 m CEP with D-GNSS corrections.
It concurrently tracks GPS, BDS, GLONASS, Galileo, QZSS, NavIC and SBAS in L1 and L5 bands, including BDS-3 B1C/B2a signals.
Dual-band reception significantly reduces multipath errors and improves acquisition speed, delivering much better positioning stability in urban canyons and near buildings.
Yes. NavIC L5 reception is supported (optional configuration with special firmware), and a NavIC-only positioning configuration is also available.
