8.2One fleet or Flip-Flop navigation setup

When the navigation option is chosen, one aux. line process descriptor will correspond to each fleet.

There is no modification in the acquisition table only one process type is needed.

In it, a stack of one must be used. In the Aux. Corr. Descr., the button by fleet needs to be selected.

Then the auxiliary description has to be entered for each source. In the example below, the description is done for flip-flop operation; therefore two fleets are described, using the same DPG and the same pilot.

8.3Slip sweep navigation setup

The setup is similar to the one of single fleet and flip-flop one.

When the navigation option is chosen, one aux. line process descriptor will correspond to each fleet; there is no modification in the acquisition table except only one process type is needed.

In the Aux. Corr. Descr., the button by fleet needs to be selected. Then the auxiliary description has to be entered for each fleet.

Using this feature, an acquisition is started as soon as any fleet is ready at any VP.
