Inertial Sense Logo

Micro Rugged INS for UAVsInertial Sense is a leading developer of miniature high-performance GPS Inertial Navigation Systems (INS), Attitude Heading Reference Systems (AHRS), and Inertial Measurement Units (IMU) for UAVs (unmanned aerial vehicles), UGVs (unmanned ground vehicles) and other robotic platforms.

Their sensor units are ideal for a wide range of unmanned systems applications, such as UAV navigation, platform High Performance Miniature Inertial Sensorsstabilization, antenna and camera pointing, and object tracking.

All products feature onboard GPS (GNSS) receivers and are available as board-level units or as rugged self-contained modules in a machined aluminium enclosure.

µINS Dual – Dual GNSS Heading Sensors

Miniature Dual-Antenna GNSS-INS Compass

The µINS Dual is a precision miniature GPS-aided Inertial Navigation System (GPS-INS) that, like the µINS+RTK, incorporates all functionality of the µAHRS and outputs orientation, velocity, and position. With dual on-board GNSS receivers, the µINS Dual uses accurate compassing to resolve accurate True North heading in challenging environments with magnetometer interference, as well as stationary applications. Sensor data from MEMs gyros, accelerometers, magnetometers, barometric pressure, and GPS/GNSS is fused using state-ofithe-art algorithms to provide optimal estimation.

The µINS Dual is ideal for high-accuracy antenna and radar pointing, as well as navigation of aerial, marine and ground-based unmanned vehicles in conditions that present challenges for magnetometers. Development kits featuring the rugged module or a convenient evaluation board are available for rapid prototyping and integration into existing applications.

µINS + RTK – Miniature GPS-Aided INS

GPS-INS for Accurate Attitude/Orientation, Velocity and Position

The µINS is a precision miniature GPS-aided Inertial Navigation System (GPS-INS) that uses state-of-the-art algorithms to combine outputs from MEMs gyro, accelerometer, magnetometer, barometric pressure, and GPS (GNSS) sensors, providing high-accuracy estimates of attitude/orientation, velocity, and position.

Real Time Kinematic (RTK) Position Accuracy – RTK base station corrections data can be applied to achieve enhanced precision down to 3 cm.

Outputs are GPS UTC time synchronized, and all units are fully calibrated for bias, scale factor, and cross-axis alignment, allowing for maximum sensor performance.

User-controllable I/O includes 9 GPIO, 5 Servo Outputs and 4 Analog Inputs. Output is fully configurable and available as binary or NMEA. A development kit (SDK) is available for rapid prototyping and integration into existing applications.
