Inertial navigation is a technique in which measurements provided by accelerometers and gyroscopes and possibly other sensors are used to calculate the position and orientation of an object in real time. Inertial measurement units (IMUs) support the navigation calculation by providing real time incremental inertial measurements of the body of interest. IMUs contain three orthogonal gyroscopes, measuring angular velocity, and three orthogonal accelerometers, measuring linear acceleration. By processing signals from these devices it is possible to track the position and orientation of a moving object.
Physical Logic offers tactical grade MAXL-OL-2000 open-loop MEMS accelerometers and MAXL-CL-3030 closed loop sigma-delta MEMS accelerometers. These accelerometers are designed with special in-plane bulk micromachining technology, in order to achieve improved performance over a wide sensing range.
Physical Logic’s in-plane bulk micromachining open loop and closed loop accelerometers are integrated in various tactical grade inertial navigation systems.
In addition, an inertial grade closed loop accelerometer is in the final development stage, and will be presented to the market in 2018 with sensing ranges from 15g to 70g.
Physical Logic’s MEMS accelerometers are designed and manufactured in Israel. They are all ITAR free and the MAXL-OL-2002C is export controlled free.
