📡 Unlock Satellite Accuracy: Inside the Aerium Datum GNSS System

Based on u-blox NEO-M9N and BMM150 Magnetometer

When your mission depends on precise, reliable positioning, the Aerium Datum delivers. Built around the advanced u-blox NEO-M9N GNSS module and integrated with the BMM150 magnetometer, Datum is engineered for drones, rovers, and robotics systems that require top-tier performance in a compact footprint.

Whether you're flying a Pixhawk-based UAV or developing custom autonomous platforms, Datum brings powerful features and plug-and-play simplicity to your next project.

Multi-Band GNSS, All-in-One Form Factor

Datum utilizes the u-blox NEO-M9N, a multi-band GNSS engine capable of receiving signals from GPS, Galileo, GLONASS, and BeiDou simultaneously.

The result?

• Faster fix times

• Higher positional accuracy

• Increased resistance to interference

With the onboard BMM150 compass, you get a fully integrated navigation solution ready for any autonomous mission.

Internal LNA for Superior Signal Reception

Datum stands out with its integrated Low Noise Amplifier (LNA), enhancing even weak GNSS signals. This leads to stronger, more stable performance in challenging environments—whether you're navigating urban areas, dense forests, or under canopy cover.

The internal LNA improves satellite lock times and positional consistency, giving you better accuracy, extended range, and higher uptime.

Pixhawk-Compatible, Plug-and-Play

Datum uses the standard Pixhawk 6-pin connector and is fully compatible with:

• ArduPilot

• PX4

• Betaflight (with external I2C magnetometer setup)

No adapters or custom wiring needed. Just mount, connect, and operate.

Customization-Ready Form Factor

Need a different GNSS module for a specific use case or regulatory requirement? Datum features a modular design, compatible with many other u-blox receivers in the same series.

Custom versions are available upon request, including modules with:

• Higher sensitivity

• Dead reckoning

• Timing synchronization capabilities

Our hardware, your mission—tailored to fit.

Dual Antenna Support: Helical or Ceramic

Choose the antenna that fits your build:

• Helical Antenna (included): Ideal for dynamic flight with excellent multi-path resistance

• Ceramic Patch Antenna (optional): Low-profile and well-suited for compact airframes or ground vehicles

Both antenna types are supported natively, and switching is as simple as connecting to the SMA port.

Field-Tested. Pilot Approved.

In extensive real-world testing, the Datum consistently achieved over 25 locked satellites under open-sky conditions, maintaining strong connections during mobile operation.

This translates to more reliable flight control, smoother GPS navigation, and greater confidence in critical missions.
