Smart Systems User’s Manual Version 1.1

Mode

There are three GPS modes available:

1) Off mode means that a GPS receiver is not connected to the DVL so no GPS

information is being logged. This should be the setting if you do not have a GPS

receiver.

2) Display every X traces mode means that every time the Noggin collects a user-

defined number of traces trace of GPR data, a data string of GPS information will be

written to the data image.

For example, the data may look like this:

Figure 5-9: Noggin Data with GPS information written to the screen every 150 traces

When this option is selected, the user is prompted to enter the number of traces to

collect before the GPS information is written to the data image.

With a Noggin 250 system, there are 320 traces per screen so using a value of 160

traces would ensure that there are 2 GPS positions on each screen.

With a Noggin 500 and Noggin 1000 system, there are 640 traces per screen so

using a value of 320 traces would ensure that there are 2 GPS positions on each

screen.
