BANANAS (Berthing And NavigatioN Aid System)
An Independent Portable Pilot Unit (PPU)
A solution to provide maritime pilots with an independent berthing and navigation aid system which solely depends on the Global Navigation Satellite System (GNSS).
The portable sensors send the exact position of the ship, her true orientation and other navigation data used by any navigation software to provide numerous e-navigation aid features.
RTK Position Accuracy
By default, its GNSS receivers are set to work with GPS+Glonass constellations. It is also possible to extend to Beidou+Galileo.
Receivers are powered by Trimble technology which automatically provides 3 levels of accuracy.
RTK: 1cm-2cm. L-Band (RTX): 4cm -10 cm. SBAS 0.5m-1m.
The 2 beacons form a dual-antenna GNSS compass with Moving Baseline RTK and Gyro-aiding. With 20m baseline the ROT accuracy is less than 0,1°/min and the HDG is as close as 0,01°. Via means of a long-range wireless radio link amongst the beacons, a very long baseline can be established (even 100m).
Rate Of Turn
The hot-swappable and rechargeable Nickel–Metal Hydride batteries (NiMH). These type of batteries are safer during transport as compared to Lithium-Ion batteries. Each battery has an autonomy of 6 hours. If needed, a battery can be replaced while a beacon is on, without any loss of power. The recharging time of a battery is 3 hours which allow enough time with a spare set to provide endless autonomy.
The PPU can send navigation data to the pilots' tablet in a range of 100m-200m.
Navigation SW Compatibility
Any navigation software that can take an NMEA feed (e.g.: Qastor, SEAiq, Orca Pilot G2, Pilot Pro, SafePilot, etc.), gives the possibility to choose this navigation sensor.
GNSS-INS data are fused together and stabilized vie means of advanced Kalman filters. This assures the most accurate and reliable augmented-GNSS navigation solution.
All antennas, modems, and firmware to make the PPU communicate with various types of radio networks are embedded: 3G/4G, UHF (410-470 MHz, ), AIS, Wi-Fi, Long-Range Wi-Fi (2.4 GHz).
2Hz NMEA wireless output is provided for integration with any navigation software
When Accuracy Matters

Pilots are in demand for berthing aid tools that provide accurate vessel location in real-time. There are several ways of providing the necessary positioning/speed accuracy. A PPU will facilitate efficient and safe maneuvering within the entire navigation harbor zone enhancing vessel trajectory. This PPU automatically offers three technological solutions to assure accurate positioning of a vessel: RTK provides an accuracy of 1-2cm.
L-Band (RTX) accuracy is 4-10cm and is delivered via geostationary satellites. Likewise, SBAS with an accuracy of 0.5-1m.
The sensors contain antennas and receivers for capturing GNSS signals. But also antennas and transceivers for communicating with VTS and to acquire real-time feeds from hydrological monitoring systems, a long-range AIS receiver, a UHF receiver to acquire RTK corrections and a GSM modem to keep a constant connection to the internet, which is also used to acquire (NTRIP) RTK corrections. The sensors operate more than 100m from the pilot’s tablets, making it a unique PPU champion fit for complex berthing maneuvers.
Each battery is hot-swappable; it can be interchanged while the beacon is functioning. The beacons contain an internal electrical-power storage that keeps the beacon running during circa 30 seconds while the battery is removed. This allows disconnecting a low-power battery and replacing it with another one which is charged. This guarantees endless autonomy. Lastly, Nickel–Metal Hydride batteries (NiMH) are safer during transport as compared to Lithium-Ion batteries.
