AheadX is aiming to create Inertial Navigation System and Attitude and Heading Reference System with high performance and reliability but smaller size and lower cost. These products could be applied in various high dynamic responses, such as UAV, robot, underwater vehicle, PTZ augmentation device, somatosensory equipment, games / film production, etc. So far, thousands of UAV and robots have been installed with AheadX navigation products. Pluto Series is designed for geeks and robot enthusiasts. It is ultra-compact low-cost Attitude and Heading Reference System (AHRS), not only providing 2D navigation solution for UGV such as self-balancing scooters, but also 3D navigation solution for UAV and UUV application. Pluto N1 is compact AHRS with high performance-price ratio. The output rate of N1 reaches 200HZ maximally, integrating triaxial gyro, triaxial accelerometer, triaxial magnetic meter as well as barometric altimeter and thermometer. Inertial sensor was temperature-compensated by -10°C to 75°C, it also provides data of barometric height and rising/falling speed besides ordinary AHRS. All the functions are integrated into a metal box dimensioned 30mm*27mm*9mm. Moreover, it is able to combine GPS/GLONASS to become GNSS/INS. Pluto provides complete solutions to either UGV or UAV.

Note: The product would be shipped five days after the order has been placed.
