FOG & MEMS combined IMU, Navigation for Self-Driving Vehicles - Tamagawa News.

Introducing a new waterproof type high-precision IMU

The IMU, which meets the IP65 waterproofing standard, was added to the line-up with high accuracy. It can also be measured on roofs of outdoor construction equipment, agricultural machinery and automobiles, as well as on unmanned transport vehicles, drones and ships.

FOG and MEMS combined IMU is a three-axis gyro (i-FOG on the Z axis and MEMS gyro on the X and Y axis) with accelerometer, which detect angular velocity and acceleration, and calculates the attitude angle (roll angle and pitch angle) and azimuth angle

It can also be used as a composite navigation device using information such as position and speed input from the external GNSS receiver. This is an inertia measurement that realizes the precision required for automatic operation.

The Tamagawa inertial measurement unit is suitable for many applications, especially automatic ones and where a pilot is absent:

Self-driving driverless cars, in which the IMU measures the various types of movement in vehicle dynamics, attitude (roll & pitch) and direction angle. An external GNSS module (global navigation satellite system) is connected to the IMU; with position and speed data, the IMU can be used as GNSS / INS / VS navigation.

  • Unmanned construction machines, in which the IMU, using gyroscope and accelerometer, offers a stable output in the presence of strong vibrations.

  • Unmanned agricultural machinery: the IMU detects the attitude (roll & pitch) and the direction of the angle of the agricultural tractor. In addition, it is used for autonomous driving combined with a GNSS global navigation satellite system.

  • Safety robots: the IMU is used for attitude control in safety robots

  • Drones: the IMU is used for attitude control in drones.

  • Automatic guided vehicles (AGV), in which the gyroscope is used to ensure high driving stability

  • Trains: the IMU detects angular speed and acceleration to measure the stabilization and comfort level of a train, with information on the GPS position.

  • Ships, in which the IMU is used for inertial navigation and the detection of the movement of boats
