Always on board


SATEL radio technology is used everywhere where data needs to be transmitted wirelessly. The high-quality radio modems are reliable even in the most difficult environments, for example at sea.

Offshore operations require reliability, safety and high accuracy. Loss of an operating network in a marine environment can have disastrous consequences. Coastal manoeuvres, docking in harbours and maritime weather and environmental monitoring, metering and alert systems demand secure 24/7 real-time data communications.

SATEL’ wireless radio technology is designed to withstand extreme conditions: saltwater, high humidity, mechanical load and vibration and UV exposure.

Applications for SATEL radio technology

Telemetry & real-time monitoring

Weather sensoring

Radio technology is used in remote weather sensors for real-time communications.

Tide gauge telemetry

Water depth measurement corrections for tidal variation on hydrographic charts uses radio technology to send data from the tide gauge to the hydrographic survey vessel in real time.

Oceanographic sensor telemetry

Offshore buoys are often installed with meteorological sensors that collect data, which is transmitted ashore in real time with radio technology.


Mareograph telemetry

Radio technology is used in nationwide network of seawater level information systems.

Camera control for offshore surveillance

Radio technology controls e.g. pan, tilt, zoom, de-ice, etc. for surveillance cameras located offshore.


ADCP data telemetry

For renewable energy studies, e.g. underwater turbines, Acoustic Doppler Current Profilers are deployed on the seabed. They can record and feed the data via cable to a surface buoy, where it can be transmitted ashore in real time with radio technology.

Monitoring of LNG bunkering vessel

Radio technology and I/O units handle data communications between the passenger ship and the LNG bunkering vessel e.g. transfer monitoring data on gas flow, pressure and level measurements, and information on emergency shutdown.

Transport and control solutions

SATEL applications others

Autonomous ships

Autonomous ships and marine vessels with IoT capability need mission-critical communications everywhere at all times. The data communications needs to be reliable even when the vessels move outside conventional terrestrial network coverage areas.

Piloting and berthing system

Correction data for GPS-based systems. Communication via radio technology helps maintaining heading and position accuracy during possible loss of satellite signal, e.g. passing under a bridge.

Oilrig transport

The heading and navigation sensors of the tugboats collect data, which is sent in real time by radio technology to the control centre. The position of the tugs is monitored from the rig, and the rig can be pulled into a correct position based on the data provided.
