JAVAD Antenna GyrAnt

GyrAnt combines the Inertial Measurement Unit (IMU) and the GNSS antenna. IMU consists of three gyro sensors, three accelerometers oriented in mutually orthogonal axes, all placed in the water resistant aluminum antenna housing. IMU provides measurements of angular velocity and acceleration. The system improves standalone position and velocity measurements of the GNSS receiver and provides the attitude.

The accelerometers used are: biaxial XY SCA-1000 and biaxial ZY SCA-1020, only Z-axis is used. The gyroscopes are Analog Devices ADXRS 613. IMU has also a power supply circuitry, ADC, and a processor controlling inertial data sampling and sending the measurements through RS-422 and CAN ports. The compensation of temperature zero drift, scale factors, and calibration of the sensor axis misalignment are implemented in IMU.

Sampling rate is 100 Hz. Communication is provided via RS422 or CAN interface.
