    Use it with Mini-Ranger 2
    Perfect for shallow water USBL tracking
    Easy to deploy on temporary over-the-side set ups
    Ethernet comms for fast position updates
    Excellent corrosion resistance

    Portable, calibration-free vehicle and diver tracking

    HPT 3000 has an internal MTi-30 Xsens sensor which provides pitch, roll and heading data for search and salvage applications which are time critical requiring turn on and track functionality. Shallow water and pipelay from anchor barges also benefit from the internal sensor being calibration free.

    The HPT 3000 Ultra-Short BaseLine (USBL) is a new smaller, lighter, high performance Ethernet interfaced USBL tracking transceiver, supporting Sonardyne’s Wideband®2 6G® instruments. This smaller HPT offers significant improvements for survey positioning for coastal and near shore operations where high elevation tracking is required in low noise environments.

    The advanced multi-element processing enables transponders to be positioned more precisely, more quickly and more robustly due to improvements in signal processing algorithms. When used as part of a complete Mini-Ranger 2 USBL system, heading and inertial navigation sensor, class leading performance is achieved.

    ‘Discovery Mode’ enables users to automatically detect previously deployed transponders including their configured address and channel, making the system easier to use. The HPT 3000 is a highly capable acoustic USBL tracking transceiver. Its multiple simultaneous channels enable robust tracking of 10 targets.

    Manufactured in Aluminium Bronze, the HPT 3000 is intended to be fitted temporarily or permanently to a vessel’s through-hull or over-the-side pole.
    The full hemispherical coverage optimises performance in shallow water environments boosting transmissions and receive sensitivity in the horizontal axis.

    Being Ethernet based enables the system to function over existing ship network wiring for rapid installation.

      FAQs

      Has anyone ever installed an echosounder and a HPT 3000 directly beside each other? Would this work?

      Your echosounder could affect USBL performance so use the Acoustic Signal Analysis and Noise Plot tools available in Ranger to identify potential issues. The Signal Analysis Tool allows you to identify and diagnose ‘False Detections’ caused by the echosounder and to then take steps to minimise this. The Noise Plot Tool allows you to analyse the background noise to which the USBL transceiver is exposed. Take various noise profiles under different operating configurations, for example, with the echosounder on and off. These will give you a good idea of the power and gain settings to use,the maximum range you can expect to achieve and the beacon power settings. If you are in any doubt, please feel free to send through the screenshots and we will look at them.

      Do deployment machines require any kind of maintenance?

      Yes. After commissioning and start-up of the system, the L/USBL transceiver, deployment machine, and gate valve will need a minimum of preventative and corrective maintenance to ensure the correct operation of the machine and consistent acoustic performance from the transceiver.

      The procedures can be carried out without affecting the calibration offsets (CASIUS) of the L/USBL transceiver. We recommend that the maintenance which comprises visual inspections of bracing points and fixings, greasing routines, and also exercising of the moving parts (particularly the gate valve), is carried out on a monthly basis. Full details of these procedures can be obtained from our Customer Support team. From a purely operational point of view, failure to carry out the maintenance can lead to mechanical issues suchas vibration of the pole which can have a significant impact on the performance of your system.

      Carrying out the correct preventative maintenance routines can not only prolong the life of your deployment machine, but also greatly improves the performance of the acoustic system and reduce the risk of operational down time.

      How sparse is a sparse LBL array?

      In theory, LBL requires a minimum of three ranges and knowledge of depth to calculate a unique position. However in the real-world, it is likely that one or more ranges will be slightly in error and so with only three ranges, it is impossible to detect and identify an erroneous range. By adding more ranges, typically five or more, it becomes easier to detect outliers and compute a high integrity position. This is known as redundancy.

      When we include the extra position change information obtained from an LBL system aided with an inertial sensor, such as our SPRINT, we can reduce the number of ranges required as we now have a better understanding of the actual movement of the target and can use this information to identify and reject erroneous ranges. The amount of assistance this gives in detecting bad ranges depends on the geometry of the ranges and the trajectory of the target. So how sparse to make an array therefore depends on your vehicle path, array design and the integrity required for the positioning.

      Does the HPT's main connector need any maintenance?

      Yes. To keep your HPT performing as it should, you should clean, inspect and lubricate the bulkhead connector. This is what the manufacturer recommends:

      AGP Connector mating surfaces should be cleaned to remove contamination and silicone build up then inspected and re-lubricated. This should be performed prior to each mating and before storage to insure correct mating as well as prolonged connector life. Connectors must also be mated and unmated correctly to ensure a proper seal and to prevent connector damage or degradation.

      1. Clean the connector using the manufacturer’s recommended “3M Silicone Spray, ECG RX2200 or Dow Corning DC200” only.
      2. Apply lubricant and carefully and thoroughly clean the connector, locking ring and locking ring threads using a non-abrasive towel (it is not recommended to insert anything into pin or socket cavities).
      3. After cleaning, thoroughly inspect the connector and locking ring and look for:
      – Cuts or abrasion to sealing surfaces (face of connector, overmold and pin cavities).
      – Bent or broken pins and sockets.
      – Deformation of the shoulder (the back of the metal locking ring presses against this shoulder to ensure connector faces mate tightly together).
      – Damaged threads, rust or corrosion on locking rings.
      4. Lubricate the connector surfaces using 3M Silicone Spray, ECG RX2200 or Dow Corning DC200.
      5. Apply a light machine oil or dielectric anti-seize to lubricate only the threaded portion of the stainless steel locking rings.
      6. Mating of locking rings should be done by hand only (do not use a wrench or pliers to tighten locking rings).
      7. Ensure this is no gap between the two face seals before thoroughly hand tightening the locking rings (by hand (the locking rings can be pulled back from the connector to allow a better view).
      8. Do not bend or twist connectors while mating or un-mating as this will damage the connector pins and sockets. Pull or push straight across the connectors. Anchor cable with foot and pull straight up if possible.

      Note: do not use Contact Cleaner, WD40, CRC, DC111 or any other solvents or heavy silicone grease to clean or lubricate AGP connectors. Doing so may cause connector damage, improper mating/sealing and shortened connector life.
