Kailani Telemetry Buoy

Seafloor to space communications for ocean floor instruments

Description

The Kailani Telemetry Buoy (KTB) implements seafloor to space communications for ocean floor instruments.

The compact sea surface buoy package is just 460mm in diameter and less than 25kg making it ideal for deployment from small boats. Inside the buoy is a battery power supply providing a minimum of 30-days endurance with longer durations possible using on-board solar photovoltaic charging. Computing power in the KTB provides for communication with ocean floor instruments, reception and batching of data and transmission by either satellite or VHF radio link.

The “Internet of Things at Sea” – IoT@Sea – is made real by the Kailani Telemetry Buoy for receiving real-time data from your deployed instruments.
