Inertial Navigation System incorporates GPS compassing.

Press Release Summary:

Incorporating MEMS sensor technology, VN-300 GPS/INS combines 3-axis accelerometers, 3-axis gyros, 3-axis magnetometers, barometric pressure sensor, 2 GPS receivers, and microprocessor in aluminum enclosure. When in motion, unit couples position and velocity measurements from GPS receivers with measurements from inertial sensors to provide position, velocity, and attitude estimates. GPS receivers also provide True North heading measurements when sensor is stationary via GPS compassing techniques.

VectorNav Launches Industry's Smallest, Most Advanced Dual-Antenna GPS-Aided Inertial Navigation System

New VN-300 builds upon proven platforms to create the industry's smallest, lowest weight, best power requirements and lowest cost on the market

ORLANDO, Fla. -- VectorNav Technologies, the leader in intelligent and high-performance inertial navigation technologies, today announced the introduction of the VN-300 Dual Antenna GPS-Aided Inertial Navigation System (GPS/INS). The follow-on product to the successful VN-100 IMU/AHRS and VN-200 GPS/INS, the miniature, high-performance VN-300 enables a wider range of applications through the incorporation of GPS compassing techniques.  The VN-300 can be used in a wide variety of industrial and military 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.  The VN-300 will be on display and available for review at VectorNav's booth #330 at AUVSI in Orlando from May 13-15, 2014.

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.

"The VN-300 is unique in that it provides a complete, high performance GPS-aided navigation solution under both stationary and moving conditions, all in a miniature and cost-effective package," stated VectorNav President, John Brashear.  "By addressing some of the most difficult issues users face when trying to integrate an inertial navigation system - high cost; large size, weight and power; unreliable magnetic environments and restrictive operating requirements - the VN-300 will enable an unprecedented number of applications."
