Precise Navigation and Docking Aid

ADX XR Lite Portable Pilot Unit

ADX XR Lite is a wireless PPU system that communicates with the Pilot's portable ECS system via standard wireless technology. The complete system comprises only three small, light, ruggedized POD units, making it ideal for transportation and operation under various conditions.

The ADX XR has been designed in accordance with the POADSS concept (Portable Operational Approach and Docking Support System), which was developed under the european Marnis project.

The ADX XR Lite is offered in 4 different versions, depending on the required positioning computation mode:

  • GPS/GLONASS uncorrected
  • DGPS via SBAS
  • DGPS via UHF
  • Uses both GPS and GLONASS Satellites - and it is ready for Gallileo
  • Ready to go right out of the box. Operational in seconds.
  • No Cables, no Wires
  • Optional AIS and VTS traffic images
  • "After purchase" upgradable to ADX XR

In order to calculate the precise position and vessel path prediction for the ship pilot, Heading and Rate of Turn are the most important observations. The wireless communication between the ADX XR Lite pod sensors makes it possible to use the ship's full width. By this, extremely accurate heading is achieved.

As a unique feature, the ADX XR Lite can easily be “after-sales-upgraded” to the most accurate ADX XR system by adding RTK communication module of your choice (UHF or Dual GPRS/UMTS Modem) to the system.
