can then go back to the Utilities menu to send a test report. When the GPS
receiver cannot acquire a fix, HACC gradually increases and, at some point, stops
at a value of 4294967.500. It is an indicative that the surrounding obstructions
prevent the GPS receiver from obtaining a fix and user should move on to a
different location.
Check
Check Iridium option forces the SHOUT nano to turn on its Iridium transceiver and
Iridium
continuously update and display signal strength information in real-time. The
Iridium transceiver remains on until user leaves this screen by pressing the BACK
button. User must be careful not to deplete the battery power by staying on this
option for too long.
Test Report
When the Test Report option is selected, the SHOUT nano immediately turns the
GPS receiver on to refresh its location data. The location information is
continuously updated and displayed in real-time whether there is a valid fix or
not. Similar to the Check GPS option, HACC can be monitored to see if a valid fix
is possible. Once a valid fix is obtained, the GPS receiver is turned off and the
most recent 3-D fix information is displayed on the screen. This information called
test report can be forced to send to a NOC server by pressing the Send soft key.
A test report has the same format as a regular position report and is being
treated as such by a NOC. Sending a test report will not disrupt or change the
tracking reporting rate.
Test Report option is a good diagnostic tool used to ensure proper operation of
the GPS receiver and the Iridium transceiver. It can also be used to manage
battery life by turning off tracking mode and strategically send on-demand
location reports. It can be considered as ―manual tracking mode‖.
