ADU5 provides precise heading, pitch and roll along with three-dimensional position and velocities at a rate of up to 5 Hz for static and dynamic platforms, making it an ideal solution for a wide variety of airborne, marine and terrestrial applications. In addition, while the ADU5 has the same dimensions and interface as ADU2, it consumes much less power than ADU2. | | | | | | | | | | Advanced Features The ADU5 from Thales utilizes a 4-boat antenna X 14-channel marine receiver configuration for optimal satellite tracking and reliable positioning. The ADU5 also incorporates signals from Satellite Based Augmentation Systems [SBAS] such as WAAS, EGNOS, and MSAT and features an embedded 2-channel 300 KHz marine beacon receiver for easy MARINE DGPS operations. The 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. Attitude angular accuracies depend on the spatial separation 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, etc. to match operating conditions. User-Friendly Operation Windows® based Evaluate™ and CalibADU™ software are provided standard along with the ADU5. Evaluate software communicates directly with the receiver for control and monitoring. It provides visual displays of | | | | | | satellite tracking information, position, velocities and attitude. It is also capable of data logging and statistical accuracy analysis. CalibADU software allows the user to determine the relative antenna vectors and calibrate the receiver with the click of a button. | | | | | | | | | | Easy Integration Packaged in a robust housing, the ADU5 can be integrated into existing boat navigation system racks. As with its predecessors, the ADU5 can be readily employed in a variety of precision GPS usages such as gyrocompass calibration, dredge positioning, oceanographic acoustic doppler current profiling (ADCP), airborne videography and remote sensing, as well as many other terrestrial, marine and airborne weapons and antenna pointing applications. | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
