MicoAir MG-902 GNSS

Step up to the MicoAir MG-902, a module that redefines “Quick Fix.” While older M8N modules are limited in their concurrent satellite reception, the MG-902’s M9 series chip can listen to all four major global satellite systems at once. This results in a faster “3D Fix,” even in urban environments or deep valleys where signal obstruction is common.

The MG-902 is not just about coordinates; it’s about orientation. The integrated QMC5883L digital compass provides stable, jitter-free heading data via the I2C protocol. With a 25x25mm high-gain ceramic patch antenna, this module maintains a strong signal link, ensuring your “Return to Home” (RTH) and position-hold features are more reliable than ever.

Key Performance Highlights:

• U-blox M9 Multi-Constellation: Simultaneously receives GPS, GLONASS, Galileo, and BeiDou for maximum satellite density (up to 32+ satellites).

• 25Hz Navigation Rate: Experience ultra-smooth position updates. The high refresh rate allows for more responsive autonomous flight and more accurate ground-speed readings.

• Integrated QMC5883L Compass: Essential for stable heading and preventing “toilet bowling” in GPS-assisted flight modes.

• Intelligent LED Feedback: Includes a power indicator (Solid Blue) and a 3D-Fix indicator (Blinking Blue), allowing for a quick pre-flight status check without looking at your goggles.

• Superior Sensitivity: The 25x25x4mm ceramic antenna is optimized for weak-signal environments, providing a “lock” where smaller antennas fail.

• Plug-and-Play Wiring: Uses a standard 6-pin connector with UART for GPS data and I2C for the compass, compatible with most modern flight controllers.
