Satellite Repetitions = 3
Globalstar has determined that in order to ensure the transmission of a packet
through their simplex data system, that every native packet must be transmitted a
total of three times. This ensures that with the high rate of change of the
Globalstar satellite constellation that at least one satellite will simultaneously be
in view of the Satellite Repeater and a Globalstar ground segment station during
a transmission. This value has been determined to be three. Do not change it.
Sat Interval Seconds Minimum = 300
The repeated transmissions are sent at random intervals. This is to reduce the
possibility of simultaneous transmission overlap from other transmitters using the
Globalstar Simplex Data System. Globalstar has established the optimum setting
for the minimum time between the repeated transmissions to be five minutes.
Five minutes is 300 seconds. Do not change this value.
Sat Interval Seconds Maximum = 600
The other boundary of the random interval described above is the maximum time
between the repeated transmissions. Globalstar has determined that the proper
time for this value is ten minutes or 600 seconds. Don’t change this value either.
Initialization Mode Minutes Function
The following is a description of viewing and configuring initialization mode
minutes. For a detailed description of Initialization mode, please see the
Operation section of this document.
This shows the number of minutes remaining before the Satellite Repeater
expires from initialization mode. This configuration parameter may also be set to
the number of minutes required by the installer. To do this, from the Satellite
Repeater Configuration Screen, place the cursor on “InitModeMins:” and press
