If you are using more than one Argos ID, the “ Number of Additional ID’s”
will need to be changed. Valid inputs of additional IDs are 0, 3, 5, and 7. The
number of additional IDs should be 0 if using 1 ID, 3 if using 2 IDs, 5 if using
3 IDs, and 7 if using 4 Argos ID numbers.
Save the configuration file to a new name. From the PTTComm menu bar,
select File, Save As and save the file to a new name. You may need the
original configuration file at a later date.
3.2.1 Loading the Configuration to the PTT
Assemble the hardware. You need the SAT ARGOS PTT, the SC532A with
power supply, and two serial cables (SC12). Before you apply power, you
should have a dummy load or antenna connected to the RF output of the SAT
ARGOS. Do not apply power to the SAT ARGOS yet. Make the following
connections:
1) PTT to SC532A using the SC12 ribbon cable.
2) SC532A to the PC using an RS232 cable.
3) Antenna or dummy load to the PTT RF output.
4) Connect AC transformer/12 volt DC supply to power source, but don’t
connect to the SC532A.
After power is applied to the PTT, it will start to transmit. Don’t let the PTT
transmit until you have the configuration loaded. Many times a transmission
from inside a building will be picked up by a satellite. To avoid unwanted
transmissions, do not apply power to the PTT before the configuration program
(Pttcomm.exe) is ready.
On the PC, load Pttcomm.exe. Click “ File/preferences” . Set the correct
communications port. Also, set the baud rate to 9600. Everything else should
be left to the default values of: UI Exit string = QQQQQQG, Platform =
WildCAT, Prompt Wait (In Seconds) = 70, Verify data as it is Written and
Simple Mode not checked.
Click on file and open the configuration file “ ARGOS.CFG” .
Click on the start button. Apply power to the SC532A; this will power the
transmitter. When the PTT is first powered, it sends a start up message out the
serial port. When Pttcomm.exe receives a startup message, the PTT is put in
configuration mode. Pttcomm.exe will give a message when the PTT and the
computer have established communications. Click on the “ Cfg” button to
send the configuration file. In a moment the software will acknowledge the
file was sent. Wait at least ten seconds before you close Pttcomm.exe or power
down the PTT.
4. Satellite Orbit Patterns
At least two satellites are operational at any given time. The orbits carry the
satellites over the North and South poles of the Earth in a sun synchronous
pattern. Orbit period is close to 102 minutes. The satellite foot print is about
5000 km in diameter. At latitudes greater than 75 degrees, each satellite
