receiver to obtain a hot-start fix. Report rate (time between reports) set to more
than two hours forces the GPS receiver into either a warm-start or cold-start fix
(~29 seconds). As a result, the ts will consume more battery power and the total
number of reports is significantly reduced. User is encouraged read the Power
Consumption section.
NOTE:
When the SHOUT ts is in the middle of sending a report and user forces it
to power off by holding down the power/back button, the ts will attempt to
complete sending the report before shutting down. A warning message will appear
on the screen and will remain until either a position report is sent or failed to
send. User can go back to the home screen by simply pressing the back button.
The ts logs and saves all position reports in its circular memory. When its memory
is full, the oldest reports are over-written. SatTerm can be used to retrieve all
position reports saved on the ts.
Reporting Rate is used to set the report frequency (time between reports) when
tracking is enabled. Once a reporting rate is selected either by a predefined rate
or by a user-entered rate, a new menu will appear requesting for the mailbox
check rate. The mailbox check rate can be the same as the reporting rate. In this
case, the ts checks the mailbox each time it wakes up to send a report. If the
mailbox check rate is different than the reporting rate, the ts will wake up in
between reports to check the mailbox without sending a position report. The ts
only accepts the mailbox check rates that are evenly divisible to the report rate.
The SHOUT ts can transmit position reports in either 30-byte format or 10-byte
format. Both of these formats are backward compatible with the SHOUT nano.
The 30-byte format includes UTC date, UTC time, latitude, longitude, altitude,
speed, course, vertical velocity, number of satellites used to obtain 3-D fix, HDOP
and VDOP. The latitude and longitude are recorded with ~0.18 meters resolution.
The 10-byte format includes UTC time, latitude, longitude and PDOP. With UTC
date omitted, the ts relies on the NOC server to record the date. Encryption
cannot be used with the 10-byte format. Latitude and longitude are recorded with
~1.1 meters resolution. The 10-byte format is selected for the purpose of airtime
cost-saving.
The ts can also send position reports in PECOS Message Structure (PMS). The PMS
complies with the Blue Force Tracking Data Format Specification. The ts is shipped
