Ad Navigation ADX XR

Ultra Precise Lock Approach and Docking:

ADX XR Portable Pilot Unit

The new and lightweight ADX XR - Extreme Reliability - provides the highest possible level of accuracy and reliability for PPU, Portable Pilot Unit, applications. Operated independently, the ADX performs even better than most ship-installed gyros, ROT sensors, and speed logs.

ADX XR 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.

  • Provides maximum safety and efficiency during all scenarios
  • 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

To meet the exacting demands of navigating and docking large vessels, the measurement of low speeds, precise heading and Rate of Turn is of utmost importance to the pilot. The ADX XR Portable Pilot Unit system derives these measurements using state-of-the-art GPS/GLONASS Real Time Kinematic (RTK) techniques along with precise RoT sensors.

A unique feature of the ADX XR PPU is the incorporation of two modems allowing reception of RTCM RTK corrections via two different UMTS providers. Automatic selection of provider minimizes loss of corrections, resulting in almost zero downtime. Continuous high precision RTK mode during docking and lock approach translates to extreme reliability.
