Overview

AGI is pleased to introduce our second generation AGILOG Electromagnetic (EM) Speed Log System AGILOG 2 following on from the unprecedented success of its predecessor. Developed for use on surface warships and submarines, AGILOG 2 sets the standard for accurate and reliable measurement of ship’s speed through the water, an essential element in navigation and weapons system integration.

ABOUT

AGI’s international reputation stems from over 40 years of experience in the design and manufacture of ship’s log systems for 45 navies worldwide. Covering all classes of vessels – from nuclear and conventional submarines, aircraft carriers and frigates, to fast patrol boats, mine-hunters and fleet support ships.

AGILOG 2 is based on the well-established electromagnetic principle that a voltage is induced in a conductor by a moving magnetic field. By using the sea water as a conductor, an output is generated as the vessel progresses. Electromagnetic speed measurement is passive in operation and therefore particularly suitable for use in submarines and warships. The EM technology provides reliable and robust speed availability when compared to some alternative technologies.

AGI’s products are highly customised items and are based on a modular design. The AGILOG 2 Speed and Distance Transmitter Unit (SDTU) provides a wide range of system interfaces and expansion options. AGILOG 2 provides single or dual axis speed measurement, with multiple RS422 serial outputs and Ethernet interfacing built in.

AGILOG 2 also offers GPS assisted calibration which uses ground speed data to calculate the average true speed over a calibration run. This method does not depend on accurate distance and time measurements and is therefore easier to accomplish.

System Configuration: Typically the AGILOG 2 system comprises of the SDTU, Underwater Sensor(s) (or Probes) and Multi-Function displays with potential for an optional Data Distribution Unit for full system expansion capability.
