Abstract

The highly accurate mechanized platform inertial sensors without any external aiding signals had already achieved the positioning accuracy of 100 m in 1970s However this type of inertial sensors is very bulky and power consumption In addition these inertial measurement units (IMUs) are complex in the batch fabrication due to multitudinous parts so the cost has been always high Despite the expensive IMUs the accuracy requirements only conform to the applications For instance the IMUs applied in the civil aviation don’t need the excellent accuracy for free inertial since the radio receivers are integrated with the IMUs The new materials reduction of components and innovative techniques for the inertial sensors are able to decrease the cost as well Cold atomic interfered (CAI) IMUs based on their bias stability and random walk can provide significantly improved positional accuracy (
