Aldebaran ALD-NS3500S FOG Inertial Navigation System

The challenge

Larger UAV platforms need more accurate navigation systems, and a FOG INS is what is typically used for them.

Through extended GNSS outages, an airborne platform needs low drift from its inertial sensors, and it needs accuracy and stability in dynamic flight.

How we solve it

Aldebaran ALD-NS3500S is a rugged, GNSS-aided, tactical-grade FOG INS, suitable for positioning and pointing on airborne platforms. It gives position, velocity, attitude and heading from one unit.

  • Closed-loop fibre-optic gyros

    Gyro bias instability of 0.1°/hr and angle random walk under 0.012°/√hr. The gyros hold their bias under vibration.

  • Keeps navigating when GNSS drops

    Pure-inertial navigation through short GNSS outages. External air data, velocity, position and magnetometer inputs can aid it further.

  • Multi-frequency GNSS built in

    445-channel L1, L2 and L5 receiver for GPS, GLONASS, BeiDou, QZSS and NavIC (IRNSS), with under 0.8 cm horizontal accuracy in RTK mode.

  • Accurate attitude and heading

    Roll and pitch to ±0.05° (2σ, static) and heading to 0.3° RMS with GNSS in dynamic conditions, as Euler angles or quaternion at 100 Hz.

  • Ready in minutes

    The parameter estimation engine gives fast alignment and tactical-class navigation within minutes.

  • Isolated interfaces, continuous self-test

    Isolated RS232, RS422 and 1PPS in NMEA or binary, isolated 12 to 32 V DC input under 12 W, and continuous built-in test.
