Iridium NAL SHOUT ns User Manual page 39

 GPS Always On: Forces the GPS receiver to remain on between reports, allowing the
SHOUT ns to have immediate location information (GPS hot start, assuming the SHOUT
ns always has full view of the sky) each time it is ready to transmit a tracking report.
o When low-power consumption is not critical, enabling this option is recommended
for faster GPS acquisition and more accurate location information. If the SHOUT ns
turns off to sleep while idle, the GPS receiver also turns off.
o The AT command associated with this setting is ^GAO.
 Start-Up Mode: Sets the operating mode for when the unit is powered on or wakes up
from sleep. The default is to power up the unit in tracking mode to allow the unit to
begin tracking after a power cycle and to automatically send reports at a
predetermined interval. Alternatively, the SHOUT ns can also be configured to turn on
in command mode, allowing users to enter AT commands via a connected computer.
o The AT command associated with this setting is ^START.
 Tracking Log: Forces the SHOUT ns to save all tracking reports, whether successfully
sent or attempted during tracking mode, to nonvolatile memory.
o The device can save up to about 4,000 reports in a circular memory (oldest saved
reports are overwritten when memory reaches maximum capacity).
o SatTerm can be used to retrieve tracking reports at a later time using Options >
Tracking Log.
o The AT command associated with this setting is ^DLTRK.
 Max. Queued Reports: Sets the maximum number of reports that can be queued on
the SHOUT ns for retransmit.
o This setting applies only if Queue Failed Reports, Queue Restricted Reports, or both
are set (see section 5.2.2.2 Tracking Profile Settings).
 A restricted report is a report that attempts to send while the Iridium link is
configured to be disabled. For example, if Iridium is disabled in a certain
geographic area by a geofence, any reports that attempt to send while in the
geofence would be considered a restricted report. In this case, queuing
restricted reports would cause these reports to be queued to retransmit when
outside that geographic area.
