Portable Pilot Unit for Ultra Precise Approach and Docking Manoeuvres
- The world's most precise and reliable PPU for ultimate pilot assistance
- Independent system more accurate then ship-installed gyros, ROT sensors, and speed logs
- For maximum efficiency and safety during challenging jetty manoeuvres and navigating in confined and tidal waters
- Installed and operational within only a few minutes.
- AIS and VTS traffic image available via wireless AIS and broadband internet connections
- Fully compliant with the IPPA standard
- Fully tested and approved by the Dutch Pilot Organisation
To meet the 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 system from AD Navigation derives these measurements using "state of the art" GPS/GLONASS Real Time Kinematic (RTK) techniques along with Fiber Optic Gyro sensors. The technology is mounted in a small rugged suitcase for ideal portability.
Within only a couple of minutes of installation, the pilot has access to ultra-precise navigation data. The data provided by the ADX system is completely independent from the ship instruments, and there is no need worrying about poor communications to the ship officers.The ADX PPU is transmitting the navigation data to the pilot laptop via a wireless LAN connection. The pilot would have full access to the navigation data all over the bridge. A rugged laptop operates the world's most advanced pilot software Qastor.

Unique Combination of GPS and GLONASS Positioning Signals
The ADX system makes use of combined GPS/GLONASS technology. GLONASS is the Russian positioning system equivalent to the American GPS. The ADX system is seamlessly making use of the 14 available GLONASS positioning satellites in addition to 28 GPS satellites. On average, the ADX system is tracking 12-15 positioning satellites, which is 40-60% more compared to a regular GPS based system. Combining GPS and GLONASS improves all aspects of satellite navigation. In particular, this is of great advantage during docking operations close to gantry cranes and other sources that generates unwanted noise and signal reflections (multipath)
Performance
With no latency, ADX system is offering the following real-time precision in dynamic mode (RMS):
- Position: 1-2 cm
- Vertical: 2-3 cm
- Speed: 1 cm/sec (0.02 knots)
- Heading: 0.05 deg
- ROT: 0.1 deg/min
ADX PPU unit:
The AD Navigation ADX system requires GPS/GLONASS RTK correction signal from a special shore-based differential GPS station. Positioning accuracy is in the order of 1-2 centimeters, with a typical range limit of approximately 7 miles. An optional 10 Watt UHF booster increases operational range to 15 miles with some minor loss in positioning accuracy. This meets the docking requirements of most large ports in the world.
On the vessel side, two GPS/GLONASS antennas are deriving true heading, even outside RTK base station range. Adding the observation from the integrated Fibre Optic Rate of Turn sensor into the extended Kalman filter in Qastor, the ADX provides heading and ROT data at an extremely high level of accuracy and reliability. Far beyond today's advanced ship installed sensors.
Navigation electronics are housed in a rugged suitcase. The suitcase is housing a ruggedized laptop as well as the GPS/GLONASS antennas and necessary accessories.
The system is powered using rechargeable Li-ion batteries, firmly integrated to the suitcase. The charger input connector is located on the outside of the suitcase. Unique power management technology is integrated, and the user is supposed to hook up any VDC 6-28 power source for the battery charging, alternatively used as backup power in case the batteries are drained.
Features:
- WLAN Range > 100 m
- Battery life: 12 hours
- Integrated power management and charger intelligence
- Power input. 6-28 VDC
- Space reserved for pilot laptop
- Weight: 12 kg
