COMPANY INFORMATION
ML is a national high-tech enterprise that has been focusingon using inertial navigationand information fusion technology to solve the accuracy and real-time needs ofvarious types ofmoving objects for navigation information such as position and attitude. Our products coverhigh-tech sensor products from MEMS industrial-grade inertial navigation chips to high-precisioninertial navigation modules, which are mainly used in autopilots ofunmanned systems (includingautopilot/drones/unmanned ships) , satellite tracking,robots, intelligent pursuit, high-speedrail/bridge/dam mapping and other fields.
ML has accumulated strong product R&D and innovation capabilities through years ofaccumulation in chip design, process manufacturing, industry algorithms and calibration capabilitiesin the MEMS inertial industry. At present, the company has obtained several invention patents andsoftware copyrights, covering MEMS inertial navigation chips and modules, and has successfully usedthese patents to realize product transformation.
