Ashtech ADU5

Setting a new standard for attitude determination and real-time positioning, the advanced ADU5^TM from Magellan delivers unsurpassed accuracy in a rugged, full-function system. ADU5 provides precise heading, pitch and roll along with three-dimensional position and velocities at a rate of up to 5 Hz for both static and dynamic platforms, making it an ideal solution for a wide variety of airborne, marine and terrestrial applications. Built on the strength of Magellan experience, ADU5 shares the same dimensions and interface as its predecessor, ADU2, while providing superior performance and consuming much less power.

Advanced Features

ADU5 is a 14-channel receiver utilizing a 4-antenna array for optimal satellite tracking, to provide accurate and reliable positioning. Assisted by correction signals from Satellite Based Augmentation Systems (SBAS) including WAAS, EGNOS, and MSAT, ADU5 also features an embedded 2-channel 300 KHz beacon receiver for easy DGPS operations. ADU5 employs on-the-fly integer ambiguity resolution techniques, using carrier phase measurements from the 4 onboard GPS receivers, to provide instantaneous 3-D attitude information. High attitude angular accuracies are achieved through the use of spatial separation measurements between the four antennas. ADU5 can provide accuracies of 0.1 degree for heading and 0.2 degree for pitch and roll using a 2-meter antenna separation. ADU5 also features a unique Kalman filter with user selectable dynamic modes such as ship, aircraft, adaptive, and more, to match operating conditions.

User-Friendly Operation

Windows^®-based Evaluate^TM and CalibADU^TM software is included to enable direct communication with the receiver for controlling and monitoring. Evaluate software provides visual displays of satellite tracking information, position, velocities and attitude. It is also capable of data logging and statistical accuracy analysis. CalibADU software enables you to determine the relative antenna vectors and calibrate the receiver with the click of a button.

Easy Integration

Packaged in a rugged housing, ADU5 can easily be integrated into existing navigation systems. As with its predecessors, the ADU5 can be readily employed in a variety of precision GPS applications, including gyrocompass calibration, dredge positioning, oceanographic Acoustic Doppler Current Profiling (ADCP), airborne videography and remote sensing, as well as many terrestrial, marine and airborne weapons and antenna orientation applications.
