Attitude / Orientation Sensors
VN-100 Attitude Heading Reference Sensor AHRS / IMU Family
VN-100 Inertial Measurement Units (IMU) and Attitude and Heading Reference Systems (AHRS) are available in surface mount or aluminum encased Rugged modules.
VN-100 sensors compute and output real-time, drift-free attitude solutions (i.e. 3D orientation), continuous over a full 360° motion range.
Surface Mount Inertial Measurement Unit (IMU) and Attitude Heading Reference System (AHRS)
VN-100 SMD (Surface-Mount Device) is a miniature, surface mount, high-performance Inertial Measurement Unit (IMU) and Attitude Heading Reference System (AHRS). It was the first AHRS/IMU on the market to offer calibrated, high-performance, industrial grade MEMS sensors and quality sensor fusion algorithms in a single surface mount package.
The sensor incorporates 3-axis gyros, 3-axis magnetic sensors, 3-axis accelerometers, a barometric pressure sensor and 32-bit processor, in a miniature surface mount construction with a mass of just 3 grams.
In addition to providing calibrated sensor measurements, VN-100 SMD computes and outputs real-time, drift-free 3D orientation over the complete 360 degrees of motion.
Ruggedized Inertial Measurement Unit (IMU) and Attitude Heading Reference System (AHRS)
The VN-100 Rugged is a miniature, high-performance Inertial Measurement Unit (IMU) and Attitude Heading Reference System (AHRS), with a lightweight, robust aluminum enclosure. The sensor is the smallest industrial grade IMU/AHRS commercially available, with a mass of only 13 grams.
Incorporating the same suite of advanced MEMS sensor technologies as VN-100 SMD, VN-100 Rugged has a clamshell precision anodized aluminum enclosure that allows for easy application integration and provides protection from board stresses and hazards due to harsh environmental conditions.
The use of precision CNC milled aluminum parts ensures that the axis alignment provided by the factory calibration process is maintained during installation in its final configuration.
Ground based robotic vehicles operate in a wide range of environments where magnetic interference often makes heading determination difficult. The VN-100 range utilizes proprietary adaptive filtering and disturbance rejection algorithms which provide more accurate and stable heading measurements when magnetic interference is present. Vibration from nearby electric motors can be eliminated utilizing the on-board adaptive filtering capabilities provided by the Vector Processing Engine algorithm.
AHRS/IMU for Unmanned Underwater Vehicles UUV
The VN-100 range is well suited for underwater vehicle applications where precise heading, pitch and roll measurements are required. The sensor is capable of operation in any orientation and is not hostage to problems associated with gimbal lock. VN-100 is the only Attitude Heading Reference Sensor in its class to offer on-board hard & soft iron calibration capabilities This allows the sensor to compensate for magnetic distortion from nearby electric motors and batteries while in the field.
GPS Aided Inertial Navigation Systems
VN-200 GPS/INS Product Family
VN-200 GPS-Aided Inertial Navigation Systems (GPS/INS) combine an advanced GPS module with the latest in MEMS inertial & pressure sensor technology. The VN-200 range is the smallest and lightest GPS/INS range currently available worldwide, with products well suited to applications operating under highly dynamic conditions.
Available in surface mount or aluminum encased Rugged modules, the sensors rely on aerospace-grade navigation algorithms, computing coupled position, velocity, and attitude estimates at an unparalleled rate of 200 Hz.
Surface Mount GPS-Aided Inertial Navigation System
The VN-200 SMD (Surface-Mount Device) is a miniature, surface mount, high-performance GPS-Aided Inertial Navigation System that combines MEMS inertial sensors, a high-sensitivity GPS receiver, and advanced Kalman filtering algorithms to provide optimal estimates of position, velocity, and orientation for industrial applications.
The system incorporates an on-board high sensitivity 50-channel u-blox GPS module, and an MCX connector is provided for connection to an external active antenna.
The VN-200 Rugged is a miniature high-performance GPS-Aided Inertial Navigation System combining the same MEMS inertial sensors and high-sensitivity GPS receiver as the surface mount VN-200 SMD, with a lightweight, robust aluminium enclosure.
Precision alignment holes are provided to ensure accurate installation and a 10-pin locking connector is used to provide a reliable connection in severe high vibration or shock conditions.
Building on the architecture of the VN-100 and VN-200 lines, the VN-300 combines 3-axis accelerometers, gyros, magnetometers, a barometric pressure sensor, two GNSS receivers, and a low-power micro-processor into a rugged aluminum enclosure or surface mount package. Advanced Kalman filtering algorithms to provide optimal estimates of position, velocity, and orientation.
The VN-300 is the world’s smallest and lightest high-performance Dual Antenna GPS-Aided Inertial Navigation System (GPS/INS). The VN-300 couples measurements from the onboard GNSS 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 or GNSS receiver or AHRS.
The VN-200 provides exceptional performance for autonomous control of unmanned aerial platforms. With an update rate of 200 Hz, high bandwidth, low-latency position and attitude measurements can be directly connected to the necessary control loops. The VN-200 calibration procedures ensure a high accuracy pitch and roll solution relative to the horizon while the on-board barometric pressure sensors provide autonomous aircraft with greater ability to precisely hold altitude.
GPS/INS for Camera Stabilization
The high pointing accuracy and low latency of the VN-200 makes it well suited for airborne camera stabilization applications. Utilizing the GPS and pressure sensor measurements together with the inertial sensor measurements, the onboard INS algorithm estimates absolute heading to better than 1 degree in yaw, pitch and roll in dynamic environments.
GPS/INS for Marine Antenna Stabilization
Maritime VSAT satellite communications require stabilized antennas that remain pointed at the satellite in order to ensure continuous data transmittal. Regulations require that pointing accuracies remain better than 0.5 degrees to maintain active transmission. This requirement demands highly accurate, precise and low latency attitude and angular rate measurements.
The dynamic motion common to rough sea conditions makes this a difficult task for most industrial grade MEMS-based inertial navigation systems. The VN-200 GPS assisted inertial navigation algorithm is capable of compensating for dynamic acceleration induced from the motion of the vessel while maintaining accurate orientation measurements. With a full filter state update rate of 200 Hz, the VN-200 provides extremely low latency attitude and angular rate measurements, critical for closed-loop control.
