Olex Integrates Spatial into Their Survey Vehicles

1

Background

Nexans Olex has successfully integrated Advanced Navigation's Spatial INS into their hydrographic survey vessels. Spatial is a ruggedized miniature GPS aided inertial navigation system and AHRS that provides accurate position, velocity, acceleration and orientation. It combines temperature calibrated accelerometers, gyroscopes, magnetometers and a pressure sensor with an advanced GNSS receiver.

Challenge

Olex was seeking a replacement inertial navigation system to integrate into their multibeam sonar mapping systems. They needed more accurate position & orientation data than their existing inertial navigation system could provide and also wanted to make the system more affordable to bring in customers who were previously excluded due to the high costs.

Resolution

Spatial was chosen amongst other navigation systems because:

  1. Spatial offers better performance than competing systems.
  2. Spatial is much more reasonably priced than other motion sensors in multibeam sonar mapping systems offering the same or lower levels of performance.

Another key advantage of Spatial is its high compatibility with existing systems allowing it to be integrated with Atec, Wassp, HGPS and many other platforms.

Results

The use of the Spatial system resulted in higher accuracy data and better mapping. Precise navigation data is a key focus with Spatial, promising to deliver 0.1 degrees accuracy in pitch and roll, 0.2 degrees in heading, and 5 cm or 5% in heave. All of this is done at an exceptionally competitive price making it a popular choice in the hydrographic survey market.

Experimental testing from Olex demonstrates the easy installation, accurate data & wide range of compatibility of the Spatial system to existing platforms.
