Frontier Geomatics Inc. is a full-service NovAtel SPAN representative for airborne and mobile mapping. SPAN is a positioning and attitude measurement system consisting of a GNSS receiver and an inertial measurement unit (IMU).

Unlike other technologies SPAN’s principle is very straight-forward: you connect an IMU to a NovAtel GNSS receiver. This tight hardware integration not only results in a much lower system price, but also brings important benefits with it. Only NovAtel's SPAN has this deep integration of IMU and GPS hardware that no other manufacturer can offer or attempts to compensate by software.

A GPS/IMU system does not have to be exclusive for scientists any more and is simple to operate. After all, it is just an aiding sub-system for your overall mapping projects.

Crucial Benefits

Shorten your turns

There is no more need for the pilot to keep the banking angles low for any airborne survey. With NovAtel’s deeply integrated GPS/IMU technology there are practically no limits to the turns you can fly and still maintain perfect positioning and attitude accuracy on every flight line.

Save time and fuel and forget about exceeding bank angles for good!

Because the SPAN’s GPS receiver also runs the IMU algorithms at the same time as tracking GPS/GLONASS, it receives phase updates from the IMU whenever a satellite is blocked or lost. As soon as it comes back into view the receiver locks on to it almost instantly, assuring that you record all data available.

Other system vendors attempt to compensate this lack of hardware integration by tightly-coupled software alone. The effectiveness of this software-only method is limited. NovAtel’s Inertial Explorer deploys these algorithms as a standard too.

Rather than just theoretical simulations we have actual flight data from our customers banking over 70° on a regular basis.

On-Site Support

Frontier Geomatics not only resells and supports NovAtel SPAN systems, but if needed, will also be on-site for the installation, integration with other sensors and operational training. With our many years experience we assist you in adapting GPS/IMU technology for your application, no matter what airborne sensor you have and what environment you use it in.

Boresighting the IMU to the sensor is critically important and we will guide you to set-up the calibration site and have an efficient work-flow for this task. Location and number of ground control points as well as flight strip pattern depends on the sensor(s) and specific mapping application. We will aim to fly the boresight while we are on-site. We will then run your imagery through Aerial Triangulation, compute the boresight angles and leave you with a Boresight Certificate.

Processing Software

Inertial Explorer

Recorded IMU and GPS data can be post-processed for increased accuracy. It has a single user interface for GNSS and IMU data processing. Inertial Explorer is an extension of the popular GrafNav software and includes RTS Smoother for tightly-coupled forward, reverse, multi-pass and combined processing.

Besides many error models for popular IMUs the user can introduce his/her own IMU error model as well. That way data from other GPS/IMU systems can also be processed with the same efficiency and accuracy. You can process all your NovAtel and many non-NovAtel GNSS/IMU systems with one software and we can show how to set this up.

GPS/IMU data quality-control is done through a familiar Combined Separation plot comparing the forward and reverse processing solutions. For a more scientific investigation gyro and accelerometer error plots can be inspected
