Introduction to Inertial Navigation System Products
The DGS100 GNSS/INS integrated navigation series product is a high-performance micro inertial device and high-performance satellite receiver module integrated navigation product launched by Wuxi Huilian Information Technology Co., Ltd. This series of products consists of Micro Inertial Measurement Unit (MIMU), satellite receiving module, data acquisition and navigation solution board, power module, etc. Through integrated reinforcement design, the products meet the requirements of high reliability and high dynamic adaptability. The Micro Inertial Measurement Unit (MIMU) consists of three silicon micro MEMS gyroscopes, three MEMS accelerometers, and a temperature sensor, which can measure angular velocity, acceleration, and temperature to meet the measurement and calculation requirements of the product's inertial unit. The satellite receiving module can simultaneously receive signals from Beidou, GPS, and GLONASS navigation satellites, providing high reliability, high-precision three-dimensional attitude, position, velocity, and time information.
By adopting an optimized combination filtering algorithm that combines the advantages of both inertial navigation and satellite navigation, the system can provide continuous and reliable output of navigation information such as attitude, velocity, position, and time, as well as raw data (three-axis angular velocity, three-axis acceleration) information from the inertial measurement unit.
