Introduction
Marport's Trawl Navigator is a high-definition netsonder, designed to operate on the
trawl headline.
It is suited for bottom trawling and will oer better performance on trawls with a small
vertical opening.
In order to eiciently follow the trawl descent, echogram ranges are configurable from
5 to 160 meters. Moreover, the sensor includes an automatic range mode: the sensor
can automatically switch to lower ranges of 20, 10 and 5 meters to get sharper pictures,
proving to be particularly useful when fishing close to the bottom.
In addition, the sensor can measure the temperature, depth, pitch and roll.
The Trawl Navigator is available in three sizes: XXL with 4 batteries for a longer battery
life, XL with 2 batteries and Stubby with 1 battery.
Applications
Here are examples of data received by the Trawl Navigator in Scala2.

Introduction and Presentation 6
The image below shows the display of data received from a Trawl Navigator installed on
the headline. Pollocks can be identified close to the bottom.
In this second example, the sensor automatic range mode is activated. The range of the
sounding is automatically reduced when the sensor gets closer to the bottom, in order
to have better quality images.

Firmware and Features
This section describes the firmware and features that must be configured on MASP to
set up the sensor.
To be operational, the sensor needs to be configured with two files:
•a firmware file (*.A2F): it is the firmware of the sensor,
•an application file (*.A2A): it defines the sensor features and options.
These files are generated via MASP.
See Uploading the Sensor Firmware (on page 23) for guidance on how to complete
the following items and download the firmware and application files.
