1.Brief Introduction

1.1 integrated navigation system (INS) is developed based on MEMS technology, with built-in positioning module and inertial measurement unit. The data fusion is realized by the built-in navigation computer, which can output real-time and accurate sensor data such as carrier attitude, orientation, position and speed.

2.Major Function

2.1 the main framework of the system (Integrated Navigation System) has the following hardware modules:

(1) The inertial measurement unit and the four frequency dual mode dual antenna satellite positioning board card.

(2) A pair of external multi-star and multi frequency GNSS antenna.

(3) Ins operation control unit.

(4) RTK communication (RS232 or Ethernet).

2.2 function description

(1) Positioning function: Based on MEMS technology, it can effectively solve the interruption and mutation of positioning results caused by satellite signal masking, and provide continuous, high-quality and high output positioning results.

(2) RTK: receive the satellite observation value and receive the information from the reference station, and calculate the RTK Positioning to achieve high-precision positioning of RTK and reach cm positioning accuracy.

(3) Inertial measurement: roll angle, pitch angle, azimuth, three axis acceleration and three axis angular velocity are obtained by IMU on board.

(4) Antenna calibration: according to the antenna and product location, calibration related data can achieve high-precision positioning.

(5) External communication: send processed data to bus through RS232, RS485, Ethernet or can communication.

(6) Data storage: ins can store antenna and position information configured by users, storage IMU calibration data, can message ID and other user information.
