About production

XW-ADU7612 inherited StarNeto’s technical advantages on GPS navigation and inertial measurement. By using more accurate close loop fiber optic gyros, Q-flex accelerometers and improved integrated navigation and attitude measurement algorithms, XW-ADU7612’s technical performance has been further improved.

Embedded with high accuracy inertial measurement units, XW-ADU7612 seeks the north autonomously. It is better to use it at sea or in the sky, this is because that XW-ADU7612 integrates dual GPS’s, outputs system’s azimuth angle as well as drift angle. When the satellite signal is completely sheltered, XW-ADU7612 enters the pure inertial navigation mode. Using its high accuracy FOG, it maintains excellent measurement accuracy in a period of time. Speaking of this special feature, the product offers more accurate and reliable solutions than using GPS, INS, or regular GPS/INS combination alone. At present, XW-ADU7612 has been successfully used industries, such as, vehicles while in motion, UAV’s flight control and reserved attitude, science investigation ships, platform stabilizations, etc.

XW-ADU7612 is embedded with three modes, which are vehicle mode(ground applications), shipborne mode(at sea applications), aircraft mode(aviation applications). As per client’s requirements, optional devices, such as, odometers, air speedometers, DVL, can be used for speed compensations. In our 3-hour vehicle test when an odometer is introduced, the position error of XW-ADU7612 was less than 300 m when it reached its origin, with a travel route of a closed curve.

产品特点

█ Autonomous north seeking function. When no GPS
    signal is available in static situation, direction and
    attitude sensing can be done with high accuracy
    inertial navigation
█ Heading values can be accurately calculated by
    dual GPS’s carrier phase measurement technology.
    The accuracy of heading depends on the length of
    the distance between the two GPS’s. The longer the
    baseline, the higher the accuracy.
█ Offers accurate drift angle for manned aerial vehicles,
    UAV’s, aerostats in dynamic situation with GPS track
    angle output.
