NovAtel IMU-P1750 Inertial Measurement Unit
The IMU-P1750 FOG-based IMU from NovAtel is a high-bandwidth commercial IMU with photonic integrated chip (PIC) technology that provides proven performance for the most demanding environments and applications. The IMU-P1750 IMU offers user-programmable data output rates from 1 to 1000 Hz.
Description
Overview
The IMU-P1750 FOG-based IMU from NovAtel delivers outstanding performance thanks to breakthrough PIC technology for increased reliability and upgraded high-performance accelerometers for the precision that autonomous platforms demand. The IMU-P1750 is available with a choice of 10g or 30g high-end accelerometers that augment performance for autonomous and manned systems with improved Bias Instability, Scale Factor, and Velocity Random Walk.
The new photonic chip technology reinvents fiber optic gyro (FOG) technology with improved reliability, unit-to-unit repeatability, and easier integration with an integrated planar optical chip that replaces individual fiber optic components. The result is a precision photonic fiber optic gyro sensor that is more durable and reliable with increased performance designed for a high level of repeatability.
The IMU-P1750 offers ease of use and high adaptability, featuring flexible RS-422 asynchronous communication with user-programmable data output rates from 1 to 1000 Hz. The package dimensions and mounting features enable easy drop-in replacement.
As the ability to tailor the output to exactly what the end user requires is key, the technology enables users to customize the desired message output from both the IMU-P1750’s photonic FOGs and integrated high-performance accelerometers. In addition, the IMU-P1750 offers users a high degree of flexibility, as the baud and data rates can be adjusted. This enables the user to minimize the communication latency, delivering accurate information even faster.
