It's our lightest AHRS at 6.7 grams.
AHRS-M1 introduces an adaptive-calibration mode.
Built for platforms where every gram counts.
Gimbals, pan-tilt units, small unmanned vehicles: every added gram costs flight time, slew speed, or payload. The AHRS-M1 is sized for exactly that constraint, and it doesn't ask for the weight back in performance.
Intelligently adapted calibration.
AdaptCal learns a platform's magnetic signature from its own motion. No traditional 12-point calibration. AdaptNav's real-time noise characterization keeps heading, pitch, and roll steady even on electrically and mechanically noisy platforms.
Precise wherever it is.
1.5° RMS static heading accuracy. Full 360° rollover using quaternions or rotation matrix. A ±16 Gauss magnetic range means it keeps working near motors and actuators that would throw off a narrower-range sensor.
Programmable at the sensor.
NorthTek, Twenty-Six Defense Maritime's onboard Forth environment, makes the AHRS-M1 the only micro-sized AHRS that's user-programmable at the sensor level.

The development kit can be used to quick start an evaluation of the AHRS-M1 or AHRS-M2 compass products. This kit can be used with the Twenty-Six Defense Maritime provided Spartacus GUI or a general-purpose serial terminal such as Tera Term on Windows or CuteCom on Linux. Spartacus can show real-time graphs of the AHRS data and the data can be streamed using the serial terminals.
