Mobile Connectivity for Near-Shore Waters

Sternula Above Deck Unit (ADU) is a maritime connectivity device equipped with a mobile network modem. It provides mobile network data connectivity for ships in near-shore waters.

The Sternula Above Deck unit can be integrated with the Sternula MMS Proxy Ship as one of several connectivity options for maritime digital services using the Maritime Messaging System.

In combination with the Sternula MMS Proxy Shore, the Sternula Above Deck Unit provides easy backbone connectivity between the Sternula MMS Edge Router Service and a supported Coast Station.

The compact unit provides a perfect balance between easy installation and high-quality performance.

Robust Design

The Sternula Above Deck Unit is a maritime connectivity device in a protective casing, fit for the harsh maritime environment, that can be fitted on the vessel’s railing. The internal placement of the two diversity antennas ensures high environmental protection and robustness with good performance.

The unit has a lever in each corner of the box that fixes the lid to the casting thereby sealing and protecting the unit. Recognizing that water will condense on the inside of the box, due to fluctuating temperatures, the box has a flexible tube attached at the bottom that allows any water to escape the enclosure.

The main task of the Sternula Above Deck Unit is to provide mobile network data connectivity for ships in near-shore waters.

How Does it Work?

The Sternula Above Deck Unit is designed for easy insallation and minimal setup. Only one cable connection to the MMS Proxy Ship/Shore is required, for both data and power in one cable. The cable itself is the installer’s choice and is recommended to be a maritime-grade Ethernet CAT6 cable.

It is easy to install the Sternula Above Deck Unit: just insert the nano SIM card into the SIM slot, then plug in the Ethernet cable connecting to the Sternula MMS Proxy Ship/Shore. All other configurations can be performed conveniently from the Sternula MMS Proxy Ship/Shore local configuration interface.
