The NaviSys GR-M02 is a high-quality GNSS receiver designed for industrial and commercial use. It is built on Airoha’s (a subsidiary of MediaTek) single-chip dual-band AG3335 engine, featuring 135 channels and supporting both L1 and L5 dual bands.

This dual-band capability allows the GR-M02 to receive signals from both L1 and L5 band satellites, effectively canceling out errors introduced when signals pass through the ionosphere and troposphere. This results in higher accuracy compared to single-band GNSS, with the GR-M02 achieving precision within 1.5 meters.

The 135 channels enable the GR-M02 to utilize more channels for faster satellite acquisition.

The GR-M02 supports smart jammer detection across GPS, GLONASS, Galileo, and BEIDOU bands. This feature enables real-time monitoring and identification of interference signals, ensuring high-precision and reliable positioning data even in challenging environments. It is particularly valuable for applications like drone navigation, vehicle tracking, and security monitoring, where accurate positioning is crucial despite potential interference.

In addition to its excellent GNSS engine, the GR-M02 features a slim smart antenna, making it compact with dimensions of 40 x 45 x 18.5 mm. This small size does not compromise its performance.

This GNSS receiver is IPX7 waterproof, fully EMI shielded, and operates within a wide temperature range from -40°C to +85°C. It also boasts ultra-low power consumption at 94 mA and supports an update rate of up to 10 Hz.

Navisys "NaviViewerAh" Tool

The manufacturer Navisys offers a user-friendly tool for easy configuration and diagnostics of the GR-M02 GNSS receiver. The 2 screenshots below display the satellite signal bars for L1 and L5, respectively.

GM-M02 Module

If you only need the module rather than a complete industrial-grade GNSS receiver, consider the GM-M02, which is the module version of the GR-U01 GNSS receiver.
