Integrated Navigation

Position, velocity and attitude from a unified navigation architecture.

Esima combines inertial measurements with GNSS through multi-sensor fusion, producing a single navigation solution for the platform.

Architecture

Two measurement sources, one navigation state.

Different Rates, One State

IMU and GNSS measurements arrive at different update rates and with different characteristics. A common estimation framework brings them together into one navigation state.

GNSS-Aided Inertial Navigation

Inertial measurements are the continuous basis of the solution, providing high-rate acceleration and angular-rate information. GNSS provides the external reference the inertial solution is corrected against.

Key Technologies

What the solution is built on.

  • GNSS

    Satellite-based positioning, including RTK-capable configurations where required.

  • IMU

    Accelerometers and gyroscopes measuring the platform's motion and rotation.

  • Sensor Fusion

    The estimation layer that combines both measurement streams.


Extensibility

The sensor-fusion framework is designed to incorporate measurements from other sensing modalities, so the sensor set can grow without changing the core estimation approach.

Designed for Integration

One architecture, different platforms.

The modular structure is intended to accommodate different hardware and platform requirements without tying the navigation solution to a single implementation.

Sensor interfaces, estimation functions and navigation outputs remain separate parts of the architecture, providing a clear basis for system integration.

The same Integrated Navigation architecture applied to representative air, land, and maritime platforms.
  • Air

    Designed for integration with airborne platforms operating across changing flight conditions.

  • Land

    Adaptable to ground platforms that require consistent navigation data across different motion profiles and operating environments.

  • Maritime

    Applicable to maritime platforms, where vessel motion from waves and sea state is continuous.
