The NaviSys GM-M02 is built on Airoha’s (a subsidiary of MediaTek) single-chip dual-band AG3335 chip, utilizing 12 nm technology. This advanced design supports 135 channels and both L1 and L5 dual bands.

The dual-band capability allows the GM-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 GM-M02 achieving precision within 1.5 meters.

The 135 channels enable the GM-M02 to utilize more satellites for faster acquisition.

The GM-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 GM-M02 boasts ultra-low power consumption at 94 mA and supports an update rate of up to 10 Hz.

GM-M02 module enables rapid deployment for AVL, timing, and other location-based applications. It supports various electrical interfaces, such as USB, RS232, and UART TTL. 

The GM-M02 integrates a smart antenna, LED, and all necessary circuits for high-quality positioning across GPS, GLONASS, GALILEO, and BEIDOU (G3B). This integration makes it a plug-and-play all-in-one GNSS module, allowing for fast adoption and high-yield production.
