1. Unmanned Aircraft

In recent years, micro-small UAVs have been playing an increasingly important role in the military as well as civilian fields. At present, the navigation of UAV mainly adopts the combination of MEMS inertial navigation system and GPS, which can not only improve the accuracy of the system, but also shorten the initial alignment time. Nowadays, the accuracy of the navigation system carried on top of the UAV is consumer level. With the improvement of the accuracy of the MEMS device and the reduction of the cost, the navigation accuracy of the UAV will be improved in the future.

2. Unmanned vehicle field

Unmanned vehicles are used to sense the external environment through on-board sensors, and obtain vehicle position, attitude information and obstacle information, so as to control the vehicle's traveling speed, steering, and starting and stopping. At present, Google, Baidu and other companies are carrying out the development of unmanned vehicles, and have carried out road experiments. When the unmanned vehicle walks under a tall building, and the GPS is blocked and can not work properly, the inertial navigation system equipped on the unmanned vehicle for a short period of time can meet the needs of the vehicle to move The MEMS inertial navigation system on the unmanned vehicle generally requires high accuracy.

3. Unmanned ship field

Due to the border patrol, water quality exploration and other tasks to take ordinary ship equipment is more dangerous and high cost, resulting in unmanned ship technology is developing rapidly. Obtaining the position and attitude information of unmanned ship is an important prerequisite for unmanned ship to be able to carry out work autonomously. Nowadays, the sensors equipped on unmanned ships mainly include GPS, MEMS inertial navigation system and obstacle avoidance radar. With the improvement of the accuracy of MEMS inertial navigation system, the inertial navigation system plays a crucial role in the acquisition of position and attitude information of unmanned ship. For the MEMS inertial navigation system carried on unmanned ship, the general consumer-grade medium-low precision can meet the demand.

4. Robotics field

A mobile robot is an automated device that can work autonomously in a fixed or time varying environment. In recent years，it has been widely used in the service industry, household, industry and other fields. Wheeled robots are similar to unmanned vehicles in terms of application, and are navigated by collecting data from sensors such as vision cameras, MEMS inertial sensors, LiDAR and odometers.

5. Other fields

In addition to the above fields, MEMS inertial sensors are also used in electronic devices such as cell phones, tablets, game consoles, cameras, VR glasses, and man-portable navigation for indoor positioning. At present, the personal safety of firefighters when fighting fires in high-rise buildings as well as the elderly with limited mobility at home is a common concern in the society. If the MEMS inertial navigation system is placed on the detector for navigation, real-time positional attitude information can be obtained, which can improve the safety factor of the monitored personnel.
