May 13, 2014 – VectorNav Technologies announced VN-300 Dual Antenna GPS-Aided Inertial Navigation System (GPS/INS). The VN-300 can be used in a wide variety of industrial applications and is well suited for size, weight, power and cost (SWAP-C) constrained applications such as unmanned vehicle systems; antenna, camera and platform stabilization; heavy machinery monitoring; robotics; and primary or secondary flight navigation, among others. Incorporating the latest MEMS sensor technology, the VN-300 combines 3-axis accelerometers, 3-axis gyros, 3-axis magnetometers, a barometric pressure sensor, two GPS receivers, as well as a low-power micro-processor into a rugged aluminum enclosure about the size of a matchbox. When in motion, the VN-300 couples the position and velocity measurements from the onboard GPS receivers with measurements from the onboard inertial sensors to provide position, velocity, and attitude estimates of higher accuracies and with better dynamic performance than a standalone GPS receiver or Attitude Heading Reference System (AHRS). The dual GPS receivers incorporated into the VN-300 also provide the added benefit of accurate True North heading measurements when the sensor is stationary through the use of GPS compassing techniques. The VN-300 is ideal for applications that require a highly accurate inertial navigation solution under both static and dynamic operating conditions, especially in environments with unreliable magnetic heading and good GPS visibility. VN-300 Differentiating Features:
- The VN-300 has the lowest size, weight, and power requirements of any dual antenna GPS/INS currently available on the market.
- With Development Kits priced around $5k USD, the VN-300 is a fraction of the cost of similarly performing dual antenna GPS/INS systems and is competitively priced with other MEMS-based GPS/INS systems that do not provide the dual antenna moving baseline RTK features.
- The GPS compass feature coupled with the GPS/INS capabilities on the VN-300 enables applications that require high accuracy position, velocity, and attitude measurements under both static and dynamic operating conditions.
- The algorithms onboard the VN-300 enable applications to seamlessly transition between static and dynamic operations without having to collect extended stationary measurements or perform specific dynamic maneuvers in flight for attitude alignment.
- The VN-300 incorporates a “True INS Filter” that does not force any requirements on alignment of the sensor to the velocity direction of a platform or specify the orientation of the sensor for initial alignment.
