TRENZ SIRIUS: Improved Pilot Unit (PPU) from Germany


by Marine-Pilots.com - published on 18 February 2025 -  9196 -

Press release from TRENZ, Germany - Picture of TRENZ SIRIUS
The SIRIUS Portable Pilot Unit is a new development from TRENZ. The electronics and software were completely redesigned over a development period of around two years. The proven compact form factor of the TRENZ device enclosures has been retained and you will recognise the SIRIUS Pilot Unit by its contrasting blue colour.

Increased accuracy

In practice, the TRENZ SIRIUS Pilot Unit achieves more accurate values in terms of position data (GNSS) and rotation rate (ROT) than its predecessor TRENZ +IP65, even if the technical specifications (theoretical values) of the integrated sensors are similar according to the respective manufacturers datasheets. This is achieved through more advanced hardware and intelligent sensor fusion algorithms.

Faster operational readiness

After switching on the TRENZ SIRIUS Pilot Unit, the device is ready for use within 25 to 30 seconds.
More than 1000 TRENZ PPU devices have been sold in more than 40 countries since 2018

USB Power Delivery and shorter charging times

With the predecessor (TRENZ +IP65), fast charging of the battery was generally only possible with the enclosed TRENZ power supply unit due to various USB charging standards in the past.
The SIRIUS Pilot Unit not only charges its batteries faster than the preceding model, but can also be charged quickly with all power supply units that comply with the USB Power Delivery standard. These include, for example, various phone and laptop chargers or the 20W USB-C power adapter from Apple.
Of course, like its predecessor the SIRIUS Pilot Unit can be charged simultaneously during operation onboard a vessel.

Longer battery runtimes

When developing the SIRIUS Pilot Unit, it was important to focus on energy-saving components and more efficient energy management. As a result, the device can be operated for longer with the same battery capacity compared to its predecessor. Depending on the respective configuration of the SIRIUS Pilot Unit, a running time of up to 24 hours can be achieved; the average running time is approx. 17 hours.

Reverse polarity protected AIS connection to the ship

In rare cases, it can happen that the so-called pilot plug on board a ship is not wired according to the standard or is wired incorrectly. This can result in pilot units from other manufacturers being unable to receive data. The TRENZ SIRIUS Pilot Unit is able to recognise problems with the wiring of the pilot plug and ensure that data can still be received.

Size and weight

With exactly the same dimensions of 130mm x 75mm x 28mm, the SIRIUS pilot unit weighs slightly less than its predecessor +IP65 (216 g).

IP65 protection class

Like its predecessor +IP65, which also bears the protection class in its name, the Pilot Unit SIRIUS is also dustproof to IP65 and protected against light water spray.

Article New Study on GNSS Interference in the Baltic Sea

by GPSPATRON Sp. z o. o. - published on 12 March 2025

GNSS interference has become a growing challenge in the Baltic Sea, affecting maritime navigation, aviation, and critical infrastructure. While numerous datasets and services, such as gpsjam.org, spoofing.skai-data-services.com, and flightradar24, report high-altitude GNSS interference based on ADS-B data, there is a significant lack of studies focusing on ground-level interference.
