Inertial Navigation System Factory

Inertial navigation systems (INS) are becoming increasingly indispensable as we move closer to a world of self-driving cars and other devices that can navigate without the need for external signals.inertial navigation system factory They’re used to determine position, direction and speed in places where GPS is either too costly or not available.

INSs are used by commercial and military aircraft, spacecraft, submarines, missiles, robots and drones as well as many consumer electronics including mobile phones and video game controllers.inertial navigation system factory INS is even built into some automobiles and is an essential component of the technology behind autonomous driving.

In general, a navigation system uses a combination of motion sensors and rotational sensors to continuously calculate by dead reckoning the position, orientation, and velocity of a moving object.inertial navigation system factory An inertial navigation system uses sensors to measure acceleration, gyroscopes to measure rotation, and a computer to combine the two data streams. The result is a highly accurate way to track position and orientation, even when GNSS is unavailable.

An INS can also act as a fall-back system to continue to compute positions, velocities and attitude in the event that GNSS signal interference is encountered such as when traveling through a tunnel, covered parking lot or tall city buildings. ACEINNA’s RTK products, for example, feature triple-redundant sensor architecture using IMUs with built-in integrity monitoring. This means that only valid sensor outputs are used, and that errant inputs are ignored or de-rated in importance.

Modern INSs use IMUs with both angular and linear accelerometers to capture a wide range of motions. Angular accelerometers, for instance, measure how much the vehicle is pitching or tilting in space (nose up or down) and yawing (nose left and right). Linear accelerometers are used to detect non-gravitational accelerations.

All of this inertial sensor data is then combined with a mathematical algorithm like Kalman filtering to calculate attitude, velocity and position. In some cases, additional sensors may be added such as a barometric altimeter, magnetic and/or speed measuring devices.

ACEINNA’s INS modules are designed to be easy to integrate with other sensors and systems. This reduces the cost of integration and downtime while delivering high performance and stability. This is especially important in the defense sector where INSs need to be integrated with multi-constellation GNSS, machine vision, barometric and RF sensors to deliver position, navigation and time synchronization (PNT) in the face of electronic warfare threats and spoofing.

The INS modules from ACEINNA can be integrated in less than an hour, saving valuable time and money. They include all of the necessary software and documentation to allow easy configuration, and support for popular interfaces and protocols.
