1.1.26.5 Trimble ABX-Two gyrocompass

  • Child of: POS25
  • Measures heading, roll and pitch, together with 3D position solutions up to cm-level accuracy. It can also provide drift-free, absolute attitude solution. This sensor is ideal for a wide variety of marine, air and terrestrial applications. The GNSS agnostic engine is driven by Z-Blade technology that allows the module not to rely on GPS to obtain positioning by using a single GNSS system, or any combination of them. The GNSS engine uses embedded L-band hardware for over-the-air satellite corrections to achieve cm/dm level accuracy. Global inland availability of RTX corrections allows the unit to not need a dedicated base station to deliver cm-level positioning. The ABX -Two uses a RTK engine to deliver cm-level accuracy for systems that use corrections from a RTK network or a local base, and achieves relative positioning by using RTK against a moving base. 3rd-party network corrections capabilities such as MAC, FKP, and VRS are included. When more than one RTK correcting data are available, the device utilizes the Trimble Hot Standby RTK algorithm. This allows it to use the sets of data simultaneously for positioning. Supports two modules that could be used for Precise Platform Position (P3). This option uses data from three antennas for full GNSS attitude. 240 channels. 2 MSS L-Band Tracking Channels.

1.1.26.6 Ashtech ADU800 gyrocompass

  • Child of: POS25
  • A 6D positioning system providing position and orientation It is a three antenna GNSS system employing on-the-fly integer ambiguity resolution techniques using carrier phase measurements from the three on board GNSS receivers to provide instantaneous 3D attitude information. In addition to the 3D attitude, the main GNSS board of the ADU800 is providing a 3D position up to centimeter-level accuracy in RTK mode.

1.1.26.7 University of Miami CARTHE drifter drifting surface float

  • Child of: POS25
  • A drifter used for physical and biological oceanography, search and rescue missions, marine pollution tracking, as well as surface current monitoring for the offshore industry and the Navy for purposes of navigation and operational risk reduction. Large scale deployments can also be used to study the upper ocean processes that control the transport of hydrocarbons in the environment. The drifter is made from PHA biodegradable plastic. The instrument is activated by a magnetic switch and can send its position every 5 minutes for a period of up to 3 months with meter accuracy using very-low cost GlobalStar Simplex telemetry systems. The client can receive the data in real-time through the Pacific Gyre LLC website, the official distributor of CARTHE drifters.

1.1.27 Ultra Short Baseline Positioning Systems

  • Child of: ICAT06
  • Systems dedicated to the positioning of subsea vehicles such as ROV and AUV. They are based on acoustic transmitted signals between one or several transponders and one acoustic antenna installed on a surface vessel. The transponders are mounted on the underwater vehicle or are fixed on the seafloor. These underwater acoustic positioning systems are coupled with inertial navigation systems.

1.1.27.1 Sonardyne Ranger 2 Ultra Short BaseLine acoustic positioning system

  • Child of: POS26
  • An acoustic positioning system for deep water, long range tracking of underwater targets and position referencing for dynamically positioned (DP) vessels. It calculates the position of a subsea target, for example an ROV, by measuring the range and bearing from a vessel-mounted transceiver to an acoustic transponder fitted to the target. It supports 6G acoustic systems and inverted USBL (iUSBL) tracking. It is available in two versions. In standard configuration, Ranger 2 allows up to 10 subsea targets to be simultaneously tracked from a surface vessel. In Ranger 2 Pro configuration, any number of subsea targets can be tracked. The positioning accuracy obtainable from either configuration can be improved by interfacing the system directly into Sonardyne Lodestar attitude and heading reference system (Optimised Ranger 2). It has an operating range of over 6000 m. It has a system accuracy of 0.2% of Slant Range (0.1% of Slant Range for optimised system).

1.1.27.2 Kongsberg HiPAP 102 Ultra Short BaseLine acoustic positioning system

  • Child of: POS26
  • A low frequency acoustic positioning system designed for use in deep water, utilising transponders with a depth rating down to 7000 metres, whilst the transducer has an operating range of 1 - 10,000 meters. The HiPAP has applications in towfish and towed platform tracking, seabed reference for dynamic positioning of a vessel, high accuracy subsea metrology and positioning, telemetry and scientific research. The system is primarily used to position ROVs and other objects in very deep water and at long ranges, using either or both super short base line (SSBL) and long base line (LBL) principles. The instrument operates in a frequency band of 10 - 15 kHz, and features narrow 15 degree listening beams, with a range detection accuracy of 0.02 metres.

1.1.27.3 Kongsberg HiPAP 502 Ultra Short BaseLine acoustic positioning system

  • Child of: POS26
  • A high accuracy omnidirectional acoustic positioning system with an operating range of 1 - 5,000 metres. The HiPAP 502 makes use of a spherical transducer containing an array of 241 computer controlled elements for accurate underwater positioning of submerged structures or underwater vehicles deployed with transponders. The spherical transducer enables an operating area of 200 degrees, and allows the system to form narrow listening beams of 10 degrees for reception of signals from the transponder. Beams can be pointed in any direction below the vessel, including horizontally and upwards toward the surface. The instrument operates in a frequency band of 21 - 31 kHz and has a range detection accuracy of 0.02 metres.
