About production

XW-ADU 7600 employs two high precision and high dynamic GPS receivers as its satellite signal sensors. Using carrier phase differential technology and fast solution integer cycle ambiguity technology, it is capable of accurately calculate the moving carrier’s azimuth angle. The system can still output high precision data for a period of time, when the GPS signal is interfered. This is made possible as the system’s attitude navigation is assisted by inertial measurement technology and maintained by high precision fiber optic measurement unit.

We performed a test on Y-5 airplane and compared XW-ADU 7600 with POS/AV 510. It turned out that our product’s performance and specifications are as good as that of POS/AV 510
