• Are there any export restrictions on the VN-100, VN-200 and/or VN-300?

    Each of the VN-100, VN-200 and VN-300 have an US Export Control Classification Number of 7A994 and are ITAR-free. For any other questions related to the export of VectorNav products, please contact us at +1-512-772-3615, or by email at sales@vectornav.com.

  • What is the lead-time for the VN-100/VN-200/VN-300?

    VectorNav typically maintains stock of the VN-100, VN-200 and VN-300 in all packaging and calibrations options. Low volume orders (< 5 units) usually ship within 1-2 days, but there are occasional delays of up to 1 to 2 weeks. For questions regarding lead times for higher volume orders (> 5 units), or to confirm lead times for low volume orders, please contact us at +1-512-772-3615, or by email at sales@vectornav.com.

  • Would you recommend the VN-100 or VN-200 for my application?

    Overall, the VN-200 provides higher accuracies and better dynamic performance than the VN-100, but the VN-200 INS filter does require a GPS fix to maintain this performance.  In the absence of GPS, the VN-200 can be operated as an AHRS and will revert back to the performance of the VN-100.

    The assumptions built into the VN-100 attitude filter can result in degraded performance when the sensor is subjected to large dynamic motion and when the surrounding environment contains magnetic disturbance from sources such as electric motors, electronics, batteries and ferrous materials.

      • The VN-100 has numerous built-in features and toolboxes to minimize these effects on performance, but obtaining high accuracies does require careful characterization, implementation, and testing for each application.
      • For example, the velocity aiding feature on the VN-100 significantly improves pitch & roll estimates in applications such as manned and unmanned aircraft, but it does require tying in measurements from an external GPS or airspeed sensor.  Even still, the attitude estimates from the VN-100 with airspeed aiding will not achieve as high of accuracies as the VN-200.
      • The VN-200 also has the added benefit of not having to rely on the magnetometers to obtain heading estimates with respect to true North once the platform is in motion.  For many applications, this simplifies or eliminates the need to characterize the magnetic environment in which the sensor operates.
      • VectorNav typically recommends the VN-100 for applications that need an attitude-only solution, that will be operated in a relatively low dynamic environment, that will be implementing the IMU measurements into an external filter, or those that are significantly cost constrained.  
    • What is the difference between IMU vs. AHRS vs. GPS/INS?

      The VN-100 is considered both an Inertial Measurement Unit (IMU) in that it can output acceleration, angular rate, and magnetic measurements along the X, Y, & Z axes of the sensor as well as an Attitude Heading Reference System (AHRS) in that it can output filtered attitude (i.e. orientation) estimates (3-DOF sensor).

      The VN-200 is a GPS Aided Inertial Navigation System (GPS/INS) that couples outputs from the GPS module with IMU measurements to provide position, velocity, and attitude (PVA) estimates of higher accuracies and with better dynamic performance than a standalone GPS or AHRS sensor (6-DOF sensor). 

    • Does the VN-100/VN-200 have to be mounted level on the application platform?

      No, the VN-100 and VN-200 will report the inertial measurements in the Sensor Frame and will report the attitude of the Sensor Frame with respect to the North, East, Down reference frame.  A reference frame rotation register is available, which provides the capability to remap the attitude and inertial measurements to any other arbitrary coordinate frame.  This feature allows the VN-100 and VN-200 to be mounted in any orientation and still report its data in a vehicle’s or other platform’s coordinate frame. 

    • 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.

    • Is Labview support available?

      Labview support is not currently available, but VectorNav continues to build on existing libraries.

    • Where can I find general information about the INS?

      We have compiled a large collection of inertial navigation knowledge & application notes, which are available here:
