The Defense Key Laboratory of high-accuracy inertial instrument and system, the Ministry of Education, acts as a supporting platform for scientific research in the Engineering Research Center for Navigation Technology. The main research interests of the center include high-accuracy inertial instrument and navigation technology, MEMS inertial sensor and system, precise electro-mechanical control system and its application. Many excellent papers have been published in academic journals both in China and internationally. We also had won 5 provincial and ministerial level scientific awards including 1 Award for Advancement in Science and Technology of Ministry of Education (first class) and 1 Award for Advancement in Science and Technology of Beijing (first class). In recent years, some new research interests have also been involved in the center, such as high-resolution space accelerometer, gravity gradiometer, etc.
