Operating Modes
★
StarNav — Night

Camera points at zenith. Proprietary star-matching algorithm computes absolute yaw and corrects IMU drift periodically.

Active at night 0.8° yaw error Star matching
☀
SolarNav — Day

UV sensor array measures sky polarization pattern. Finds heading that best explains all sensor readings. Continuous heading correction throughout daylight hours.

Active by day Continuous correction Sky polarization
Compatibility
MAVLink

Native MAVLink output. Drop-in replacement for GPS input on any compatible flight controller.

ArduPilot

Tested with ArduPilot firmware. Works with Cube Orange, Pixhawk and compatible autopilots.

PX4

Compatible with PX4 flight stack via MAVLink GPS injection interface.

UAV

Fixed-wing, multi-rotor, loitering munitions. StarNav works best in stable loiter or cruise flight.

USV

Ideal for unmanned surface vehicles over open ocean where map matching fails entirely.

UGV

Ground vehicles and autonomous rovers in GPS-jammed environments via UART / I2C.

See how it works.

Sensor fusion of IMU, sky polarization and star tracker.
Passive. No RF. No GPS dependency.
