　　XW-ADU3610 Marine Attitude and Heading Reference System Apparatus

About production

With two GPS receivers, which are connected to the main calculation and control computer with two cables, directly embedded into the two surveying antennas, XW-ADU 3610 accurately calculates the moving carrier’s information, such as, azimuth angle, pitch angle, GPS etc, by using carrier measurement technology and fast solution integer ambiguity technology.

A high precision laser gyro, made with some aeronautic institution, whose system precision is better than 0.01°, was tested with our company’s XW-ADU 3620 to compare their precisions. The test is done on the Jiujiang River with a vertical baseline of 20m and a horizontal baseline of 4m. The following two figures are the data comparison charts that we got for the test. Note: red line indicates the laser inertial navigation and green line belongs to XW-ADU 3620.

产品特点

■ With a super-long baseline (max. 1km), an
      extremely high precision can be achieved for
      heading and attitude
■ Short response time, excellent dynamic
     characteristic, stable and reliable, no
     accumulated errors
■ Developed independently, secondary
     development available as per specific
     requirements.
■ Not affected by the magnetic environment, no
      inertial drifting
■ Miniature, light weight, low price, easy
     installation
■ A real direction and attitude product designed
     and developed for ship borne systems
