Setting GAPS to Work
This chapter concerns the actions and procedures to be carried out just before starting
positioning operations. These actions are as follows:
●
Definition of the tracking parameters, see section 5.1
●
Configuration of transponders (USBL and L/USBL modes), see section 5.3
●
Measurement and input of profile celerity of sound, see section 5.2
5.1 Defining the Tracking Parameters
5.1.1
S
YNCHRONIZATION
M
ODES
The acoustic cycle of GAPS is defined as follows. The main parameter is the
Synchronization Mode
:
●
Internal Synchronization
: Interrogation time for the transponder is automatically
determined by GAPS. Internal recurrence is fixed. It is configured to a fixed value.
●
External Synchronization
: An external system sends a trigger to GAPS.
●
External Synchronization with inhibition
: GAPS minimum recurrence inhibits the
short external recurrence after a received trigger. GAPS triggered on signal rising edge as
shown below.
The configuration of positioning parameters is carried out in the
TRACKING
component from
the menu
SETUP
.
