The VIA-100G GPS/IMU by Karel Electronics.
The VIA-100G, an integrated GPS and MEMS-IMU (inertial measurement system), has been added to the ViaNav inertial navigation system family produced by Karel Electronics Corporation.
Featuring a high-accuracy fusion filter running on an embedded processor, the VIA-100G provides all the functions of a vertical reference unit (VRU), an attitude and heading reference system (AHRS) and integrated GPS/IMU system. The system contains GPS, 3D gyroscopes, 3D accelerometers, a magnetometer, a static pressure sensor and temperature sensors in a compact and rugged enclosure. The embedded processor provides driftless and real-time navigation information over a wide range of temperature in dynamic and static conditions, Karel said.
The sensors are integrated with a highly accurate fusion filter. A Kalman filter running on an embedded processor fuses data from the IMU, GPS, magnetometer, altimeter and barometer in an optimal manner to output highly accurate navigation solutions. VIA-100G outputs high-frequency position, velocity and attitude information in addition to calibrated 3D acceleration, rotation, magnetometer and pressure data.
The ViaNav product family includes other navigation products designed to be used in stability, guidance, control and navigation applications in industry. The VIA-100 line includes:
- VIA-100I, is an inertial measurement unit with 3D accelerometers and 3D gyroscopes.
- VIA-100A, is a 3 DOF AHRS that provides driftless real-time orientation information over the full 360 degrees of angular motion on all three axes. It includes 3D accelerometers, 3D gyroscopes and 3D magnetometers.
- VIA-100A+, is a 3 DOF AHRS that provides driftless real-time orientation information. It includes a multi-IMU configuration and employs an optimum filter to lower IMU noise level. It provides 3D orientation with improved accuracy and reliability.
