Description
In modern high-tech Unmanned Aerial Vehicles (UAV) and Precision Guided Systems, the requirements for smaller size, lower power consumption and lower cost have largely promoted and supported the development of MEMS inertial sensors. However, the performance of MEMS-based sensors still lags well behind that of more mature technologies, such as force-rebalance quartz pendulous accelerometers.
Recent technological advances in Control Systems are increasingly leading to more stringent mission profiles for these applications which may comprise, for example, high- dynamic manoeuvres in GPS denied environments and harsh vibration levels. The limited accuracy and precision afforded by MEMS-based platforms creates a gap in the market requiring low size and high performance at a competitive price point. The AI-Q-550 accelerometer from InnaLabs® bridges this gap.
The AI-Q-550 is the latest addition to InnaLabs® line of high quality, high performance, built in Europe, ITAR-Free sensors aimed at tactical, control, measurement and navigation markets.
The InnaLabs® AI-Q-550 offers industry-leading ±80g dynamic range in a 5cm3 form factor with extremely low vibration rectification errors. The AI-Q-550 is able to operate under the harshest of environments and offers exceptionally low output noise, and long-term stability with one-year composite repeatability errors of better than 1mg and 600ppm (bias and scale factor respectively).
