The ST90 system is equipped with the celebrated signal processing software developed by Kongsberg Maritime. This includes Hyperbolic FM (HFM) transmissions. This pulse type is also known as "chirp". It ensures a clutter free picture with very high resolution in range.
Simrad ST90 Technical specifications System diagram The system diagram identifies the main components of a basic ST90 system. Only the main connections between the units are shown. Detailed interface capabilities and power cables are not shown. Display (The second display is optional.)
The display is not a standard part of the delivery. This is a commercial item that can be purchased locally. Kongsberg Maritime may provide a suitable display. The chosen display must be designed for maritime use, and it must meet the minimum performance specifications.
Simrad ST90 Technical specifications Processor Unit description A dedicated maritime computer is provided. In this publication, the computer can also be referred to as the Processor Unit, and vice versa. The Processor Unit is a rugged and powerful computer. It is designed for long life in a demanding maritime environment.
Transceiver Unit. The heat exchanger also inhibits dust and dirt particles from entering the transceiver. The heat exchanger is powered from 230 VAC using a separate outlet. Related topics Simrad ST90, page 7 System units, page 13 110-0035138/A...
Simrad ST90 Technical specifications Hull Unit description The hull unit is used to lower the transducer down below the ship’s hull when the ST90 system shall be used. When the ST90 system is turned off, the transducer is hoisted for protection.
Related topics Simrad ST90, page 7 System units, page 13 Transducer description The cylindrical transducer allows the sonar beam to provide a full 360 degrees coverage of the water volume.

Simrad ST90 Technical specifications Note The transducer is covered with a thick red or black protective coating made of a special plastic type. The protective coating is a vital part of the transducer. It is very important that neither this coating nor the internal parts of the transducer are damaged during the handling, installation or cleaning.
The installation trunk - with a blind flange - can be ordered from Kongsberg Maritime as an optional delivery. As an alternative, the installation trunk can be manufactured by the shipyard based on the drawings in this manual.

Simrad ST90 General safety rules Safety is important. The safety precautions must be followed at all times during installation and maintenance work. WARNING The ST90 system operates on 115 VAC and/or 230 VAC at 50/60 Hz. This voltage is lethal! You must never work alone on high-voltage equipment! The hull unit is powered by a 3-phase high voltage.

Simrad ST90 Technical specifications Cables Each electric cable must be handled carefully. This is important to avoid damage to the cable. This is also important to avoid electric shock in the event that the cable is unintentionally connected to a power source.
Simrad ST90 Technical specifications The minimum requirements for the uninterruptible power supply (UPS) are: • : The input voltage must fit vessel supply voltage. Input voltage • : 230 VAC, 50 Hz Output voltage • Output power – Processor Unit + Display: 1000 W –...
If a ST90 system is connected to a local area network, data security is important. Equipment manufactured by Kongsberg Maritime is frequently connected to the vessel's local area network (LAN). When you connect a computer to a local area network you will always expose the data on that computer.
The damage done if a remote computer succeeds doing this. Kongsberg Maritime has no information regarding the complete system installation on any vessel. Systems provided by Kongsberg Maritime are regarded as stand-alone offline systems. They are stand-alone even though they may be connected to a network for sensor interfaces and/or data distribution.
