High-precision Marine Positioning Systems


High-precision Marine Positioning Systems

Thales Navigation introduced new range of solutions for high-precision marine positioning, including heading and attitude. This new family of marine GPS solutions has been designed to meet the expectations of the rigorous and demanding world of marine surveying. Precision, reliability, speed, and ease of use characterize these new Ashtech-branded solutions offered by Thales Navigation.

  • Ashtech Sagitta is intended for small- and medium-scale marine applications for which precise positioning and ease of use are equally important. It meets a wide variety of requirements, as it can be upgraded from single to dual-frequency technologies to provide meter-level to centimeter-level accuracy.
  • Ashtech Aquarius offers Real-Time Kinematic solutions for single and dual-frequency GPS technologies, including KART and LRK for centimetre accuracy up to 40 km. Up to two internal radio links can be fitted into the Aquarius receiver, thus ensuring high performance and reliability of differential corrections on different frequency bands.
  • Ashtech 3011 is the new GPS compass designed to complement modern navigation systems, such as OVERLAY radar, ARPA radar, and automatic pilot. It measures the vessel's course with an accuracy of 0.5X.
  • Ashtech ADU3 provides three-dimensional attitude: heading, pitch, and roll, along with three-dimensional position and velocity for static and dynamic platforms. It employs four antennas with 14-channel receiver configurations.
  • Ashtech Aquarius2 brings heading capabilities to precise positioning. In addition to the Aquarius functionality, the Aquarius2 adds a second set of GPS/GNSS channels which allows users to reach dual-frequency heading accuracy of 0.01X or single-frequency heading accuracy of 0.1X (2 meter baseline).
