Survey +

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.

Please see below for an overview of the system.

    Experts in GNSS and inertial technology

    Advanced algorithms in the Survey+ seamlessly blend the inertial and GNSS data to provide a smooth, real-time 3D navigation solution, even when satellite signals are blocked or disturbed. For ground based applications, a wheel speed odometer can be used to reduce the drift even further.

    One box, turnkey solution

    Combining GNSS receivers, an inertial measurement unit, internal storage and a real-time on-board processor all in one compact box, the Survey+ delivers everything you need for a complete navigation solution. All cables and antennas are included, and the Survey+ comes with an extensive software suite so you can post-process and plot your data at no additional cost.

  • Aerial photogrammetry
    Position measurements accurate down to 1 cm and orientation and speed measurements output at up to 250 Hz ensure you have the best information to reference your data.

    Coastal survey
    The Survey+ provides accurate position measurements as well as roll/pitch and heading information whether operating on sea or air.

    Topographic mapping
    Remove the need for time-consuming and costly ground surveys by directly georeferencing in real-time or post-processing.

    Asset management
    From street furniture to pylons, the Survey+ provides the information you need to efficiently survey the position of your assets.

    GIS data acquisition
    The Survey+ collects all the navigation information required in GIS applications, but has one of the best cost/performance ratios around.

    Land survey
    The Survey+ blends inertial and GNSS data to provide better accuracy and reliability compared to GPS only devices.

    Road monitoring
    Gain a precise picture of the sensor’s orientation at the exposure point with accurate roll/pitch measurements coupled to 1 cm RTK position.

    Road profiling
    A continuous stream of navigation measurements including acceleration and angular movement in all axes, ensure you have the information required.

    Mobile mapping
    The Survey+ accurately monitors how a sensor array is orientated, so data can be easily georeferenced no matter where you are.
