• What is the Sensor Explorer software tool?

    Sensor Explorer is a Windows based GUI developed by VectorNav, which provides a suite of software tools for evaluation, performance analysis, and configuration of VectorNav sensors.  The user-friendly software introduces users to many of the features built into the VN-100 and VN-200 products and is a very helpful tool in the early stages of development.

    Below is a demonstration of the sensor explorer tool:

  • Which features are included in the Sensor Explorer?

    Sensor Explorer Feature Include:

    • Graphical display of the 3D orientation of the sensor
    • Real-time graphs of the IMU data inputs to onboard filters
    • Logging data to output files for analysis
    • Import recorded test data for playback & analysis
    • Drop down menus to configure sensor settings & tune onboard filters
    • 2D & 3D hard/soft iron magnetic calibration tool
    • Dual sensor alignment tool
    • Low-level communication viewing tool

  • Can the Sensor Explorer be used with any operating system?

    • Sensor Explorer is compatible with Windows versions:
      • Windows XP
      • Windows Vista
      • Windows 7
      • Windows 8
  • Can you run two instances of Sensor Explorer simultaneously?

    Yes, you can run an unlimited amount of VN-100/VN-200 sensors simultaneously, although there might be a loss of performance as you connect to more.
  • Which software support libraries are provided with your sensors?

    We provide several software support libraries to help developers quickly integrate Our sensors into existing .NET, C/C++, and MATLAB applications.  These libraries include features such as:
    • Low-level drivers to handle serial communications
    • Complete access to all registers and features
    • Math libraries for common operations
    • Coordinate transformations
    • Magnetic calibration routines
    • C/C++ support for Windows & Linux platforms 
  • Can the Kalman filter accept additional parameters? How does it affect the calibration and the performance?

    Yes, the INS can accept external GPS data if the PPS is available from the external GPS module. If no PPS is available to the unit, an estimated data transfer delay can be provided to the unit. External GPS can improve the performance if the unit is more accurate and or able to operate more reliably in the RF environment. There is a Pressure sensor already onboard the VN-200. No support for external pressure sensor is available at this time, however external magnetometers are currently supported.

  • Must the VN-100/VN-200 Kalman Filter be modified specific to the platform being used?

    No modification must be made to the Kalman Filter itself as there are no vehicle/platform assumptions built into the standard Kalman Filter.

    The user does have the capability to change the default Kalman Filter tuning parameters to tailor performance to the end application.

    The VN-200 does provide a register input to account for the distance of the GPS antenna away from the mounting location of the VN-200.
