World’s first INS integration with Locata: OxTS Inertial+

Product News

July 22, 2015

300_200_LocataOxTS have successfully integrated a Locata receiver with their Inertial+ to create the world’s first Locata+INS device—capable of achieving centimetre level accuracy where GPS systems fail. Locata is an innovative positioning system designed to complement rather than replace GPS, by addressing the issues and shortfalls of a Global Positioning System. As always, the Inertial+ allows Locata users to take advantage of their existing technology while enjoying the extra layer of measurements an aided-inertial navigation system brings.

One of the many benefits of Locata is that it enables positioning in environments where GPS is either marginal or unavailable. Instead of using signals from satellites, a local network of ground-based transmitters can be set up to send GPS-like signals for a Locata receiver to calculate position and timing from. However, unlike GPS where signals are so weak they cannot penetrate into buildings, Locata’s signals are very powerful—approximately one million times more powerful than GPS. Additionally, the benefit of having a local-based system rather than global satellite system is that a Locata system can be set up in areas where GPS is unusable or unreliable, such as inside warehouses, on dockyards, or in open-pit mines.

OxTS inertial navigation technology + Locata positioning

By combining the technologies of an inertial navigation system and a local positioning system, users have access to an extremely reliable and robust navigation solution. Locata positioning data is fused with the IMU data in the Inertial+ with OxTS’ custom Kalman Filter, creating a full 3D navigation solution with precise position, orientation, heading, velocity, and acceleration measurements.
