GNSS systems provide great accuracy in perfect conditions, but we can’t always work in those. Surveying deep within open-cast mines and quarries, mobile mapping through inner-city buildings or attempting to make measurements near tree-cover or in tunnels can all cause significant problems. This is because GNSS satellite signals can be blocked completely or bounce off other objects causing multi-path errors. In a best case scenario the accuracy of your measurements suffer, but at worst it may not be possible to collect any data at all.
Our products overcome these problems because they don’t rely on just one measurement technology. Instead, they use both GNSS and inertial measurements in order to generate accurate and consistent position, velocity and orientation estimates. This blending of different technologies allows data to be collected even when the GNSS signal quality is poor or completely blocked. The inertial measurement unit also allows orientation and velocity measurements to be made in all axes at up to 250 Hz, giving you a clear and complete picture of the measurement platform.
The perfect route to upgrading your GNSS. Protect your investment and combine your GNSS with our Inertial+. Designed as a drop in component, the Inertial+ blends accelerometers and gyros with data from an external GNSS receiver. It gives smooth, continuous position measurements, even in poor GNSS environments. The Inertial+ is a true Inertial Navigation System at an exceptionally low cost.
The Survey+ is a compact, turnkey GNSS-aided inertial navigation system for providing stable, reliable and highly accurate position and orientation measurements. It is designed for airborne laser scanning applications as well as road surveying and pavement inspection projects. It seamlessly integrates with other on-board sensors like aerial cameras, laser scanners or LIDAR technology.
Reliable RTK 1 cm position measurements and precise roll/pitch and heading updates output in real-time provide all the information required to accurately reference Lidar data.
The combination of GNSS and inertial measurements increase reliability and accuracy in real-world situations where GPS signals can be blocked or affected by multi-path. Inertial measurements also track the platform’s roll, pith and yaw accurately.
Our sensors make it possible to accurately track the position, orientation and velocity of an exposure station in real-time of during post-process for direct-georeferencing.
Quick installation and ease of use means our sensors can be used competently with minimal training by multiple staff—allowing them to be quickly utilised in different projects.
Our Inertial+ sensors are drop-in products designed to expand and increase the ability of existing GNSS systems by seamlessly combining those measurements with inertial ones. This cost-effective solution is ideal in ground surveying applications.
The ability to maintain position, orientation and velocity measurements during GNSS black-outs or multi-path make our sensors ideal for rail surveying where deep embankments and tunnels pose problems.
With real-time measurements output at up to 250 Hz the Survey+ is ideal for high-speed road profiling surveys where accuracy and the ability to interface with external systems are important.

When Magnus Larson, survey engineer at WSP in Sweden, purchased his first OxTS Inertial+ from us in 2010, little did we know about the task that lay ahead of him. Now, a mere two years later, he has developed a brand new kind of mobile mapping system together with a company called Swedvision Automation. The newly developed GeoTracker is no ordinary mobile mapping solution. Not only is it a very reasonably priced and yet highly accurate mobile mapping sys...
XLview is a Spanish company deploying high definition street imaging technology similar to Google StreetView with a service called Fotocalle. With the OxTS Inertial+2 system on board the vehicle, XLview captured some 16,000 images during the tests in Spain....
OxTS’s RT3002 and Riegl’s Q120 scanner are perfect for cost effective mobile mapping applications. Mobile mapping, where a 2D LIDAR is fitted to a vehicle, is a very efficient method of surveying. An inertial and GPS navigation system, like the RT3002, is an essential part of a mobile mapping system. In this setup, the Q120 was fitted to a truck with the RT3002. As the truck is driven the laser scans the view out of the side of the truck. By driving up a...
