5.3 Configure deployment parameters
5.4 Test GPS and modem
6. Add 50 counts to the current buoyancy position (the initial buoyancy position) and
enter "ig (initial buoyancy position)" then push Enter.
Make sure that the float stopped at the buoyancy position from the previous step.
Make sure that there were no changes larger than one count between each buoyancy
position and no changes in the opposite direction of the count (in this case a count
that went in a negative direction,) for example, 744 745 744 745 746.
7. Enter if then y, then push Enter to freeze the float.
8. Disconnect from the float.
Configure the float for deployment and enter the correct float ID, password, and phone
number.
1. Connect to the float.
2. Start Tera Term or other terminal emulator program. The manufacturer recommends
that the user records all changes that have occurred on the float, in a file such as
F0044_mission.log.
3. Set the float ID, password, and phone numbers. Refer to the Navis Mission Control
manual and the Navis Mission Configuration manuals if necessary.
4. Enter n several times to record the serial number of the float.
5. Enter L to see a list of deployment parameters. (Commands are not case-sensitive: n
is the same as N, for example.)
6. Verify all float parameters with the parameters from the manufacturer, or the
necessary parameters.
7. Verify that the float ID, password, and phone numbers are correct.
8. Enter is to start a self-test.
9. Verify that the configuration is correct and that all tests are "pass."
Refer to
Do float self-test
not an indication of any problem.
10. Enter if, then y, then push Enter to freeze the float.
11. Disconnect from the float.
12. Stop Tera Term.
This test verifies that the GPS and modem operate correctly. Do this test outside, with a
clear view of the sky. If the float is too close to a building or other structure, it may not
connect to a satellite.
1. Take the float outside.
2. Make sure the float is vertical and that the antenna faces away from any buildings
(especially metal). Find the largest patch of sky and point the antenna toward that.
3. Connect to the float.
4. Start Tera Term or other terminal emulator program. The manufacturer recommends
that the user records all GPS and telemetry system tests (example file:
gps_telemetry_check.log).
5. Enter n several times to record the serial number of the float.
6. Enter gf to get a GPS "fix" (satellite connection).
7. Verify that it takes 110 seconds or less for the first connection and less the
70 seconds for subsequent connections.
The GPS connection can be verified with the known location of the float to make sure
it is accurate.
