Inertial Navigation
Physical Logics (PL) offers a range of state-of-the-art MEMS accelerometers for inertial navigation system (INS). The MAXL-2000 accelerometers deliver superior precision and reliable performance at a lower cost and smaller size than available by conventional accelerometers used for INS.

The small size and high shock resistance of PL's sensor allows the introduction of guidance, navigation, and control into applications previously considered out of reach e.g., artillery shells.

The performance of accelerometer can be optimized for specific requirements and applications on an individual basis.
MAXL-2000 Accelerometers can be supplied as a standalone single axis or as a dual/triad with a common electronics (ASIC).
Applications
The combination of PL's accelerometer's features, namely, small size, extreme ruggedness, and affordable cost will now enable the incorporation of inertial guidance to numerous new applications a scenario unthinkable before MEMS.

Possible applications are:
 Unmanned aerial vehicle (UAV) 
 Surface Navigation
 Marine Navigation
 Airborne Navigation
 Precision Weapons
 Artillery shells
Product Features
High accuracy in compact package

Designed to meet the needs of inertial navigation, PL provides a highly accurate, reliable accelerometer MAXL-2000 in a compact package. It is available in a 1D, 2D or 3D package.
Navigation in absence of GPS
Inertial sensors such as accelerometers and gyros are used for stabilization and control of a navigation mission accomplished primarily with GPS. However, this technology may be unreliable in certain cases (e.g. indoors/ in tunnels and caves), as well as being vulnerable to jamming. In these instances, inertial sensors pose the best solution for secure and uninterrupted guiding missions.

Physical Logics has developed MAXL-2000 accelerometers with extremely low bias stability (4 mg) and a wide dynamic range. This unprecedented level of performance makes PL's accelerometers ideal for use as a component of an INS system for navigation applications.
