SYSTEM DESCRIPTION
Introduction
The Simrad SP70 sonar is a long range omnidirectional low
freqyency sonar, designed for medium and large sized fishing
vessels, both purse seiners and trawlers. The standard frequency
is 26 kHz (triple and multiple frequencies as option), and the
beam can be electronically tilted from +10 to –60 degrees (or
optional -90 degrees).
Great emphasis has been placed on giving the best possible
presentations on a high resolution colour display. The processor
unit is controlled by Microsoft’s Windows XP operating
system, which result in a flexible choice of display modes for a
large range of user applications.
The signal processing and beamforming is performed in a fast
digital signal processing system using the full dynamic range of
the signals. In addition to the traditional single frequency
transceiver system, the SP70 sonar contains an advanced
frequency modulated filter system (FM).
The spherical multi-element transducer allows the
omni-directional sonar beam to be tilted electronically in any
direction. This allows you to automatically track schools of fish,
and to observe the whole water volume around and below the
vessel. A stabilization system is included for electronic pitch
and roll compensation.
