High Precision Fusion Positioning Terminal

HY-INS01 is a high-precision fusion positioning terminal integrating IMU and GNSS, which can provide accurate and reliable positioning information for vehicles. HY-INS01 receives GNSS raw data through satellite antenna, RTK differential data through vehicle gateway and TBOX, and receives body attitude information from chassis (such as wheel speed, steering wheel Angle, etc.), integrates its own IMU attitude information, and obtains high-precision positioning information through fusion positioning algorithm, and finally sent to the vehicle through the vehicle ETH or CAN bus. This product has the ability to provide accurate attitude, heading, position, speed, sensor data and other information to vehicles through data buses in various scenarios (highways, underground warehouses, viaducts, tunnels, city streets, ports, etc.).

Product features

High precision positioning

This terminal integrates GNSS, RTK, IMU and body attitude data. Through the fusion positioning algorithm, the terminal can output high-precision lane-level positioning information for ADAS above L2+.

Communication function(CAN -FD)

The terminal can receive the vehicle attitude data from the chassis through CAN-FD as the input of the positioning algorithm, including: four-wheel speed, steering wheel angle, gear position information. At the same time, it can realize time synchronization with the ADAS domain controller through CAN-FD to meet the AUTOSAR standard.

Communication function(On-board Ethernet)

The terminal outputs high-precision positioning results over Ethernet, receives differential service data of RTK, performs OTA firmware update and realizes diagnostic data interaction.

Standby and wake up

HY-INS01 connects to the power supply of the KL30. When the IGN_ON signal is OFF, the system enters the sleep state and shuts down the output of the location.HY-INS01 can wake up the device via IGN_ON, CAN or Ethernet. When the IGN_ON signal returns to ON or the Ethernet receives a wake-up signal, the system will wake up and start working again.
