Tracking menu allows user to enable the Indigo Xplorer TS tracking, disable tracking, set the reporting rate, set the mailbox check rate, set the position report format, cancel the emergency 911 signal and view the unit reporting data.


                                      



On/Off is used to set the Indigo Xplorer TS tracking mode. When Enable Tracking is selected, the tracking symbol  on top of the screen changes from dimmed gray to bright white. The device immediately turns the GPS receiver on to acquire a GPS fix and then attempts to transmit a position report. The next position report is sent automatically based on the reporting rate set using Tracking/Rpt Rate. A countdown timer to the next report is displayed inside the parentheses next to the tracking symbol. When tracking is enabled and the device sleeps in between position reports, the status LED flashes once every five seconds. It can be turned off during sleep to reduce power consumption by using Settings/LED. The emergency 911 button can be activated at any time during tracking mode or non-tracking mode. The device can also be powered up at any time and be used as a texting device.


When wake up to transmit a location report, the Indigo Xplorer TS antennas must have full view of the sky; otherwise, it will fail to send. A missed report will not be resent. The entire reporting duration can take up to two minutes depending on the Iridium satellite visibility and the validity of the GPS ephemeris data. Ephemeris data saved on the GPS receiver is valid for approximately two hours allowing the 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 device will consume more battery power and the total number of reports is significantly reduced.

NOTE: When the Indigo Xplorer TS is in the middle of sending a report and user forces it to power off by holding down the power/back button, the device 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 device logs and saves all position reports in its circular memory. When its memory is full, the oldest reports are over-written


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 Indigo Xplorer 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 device b n n      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.


After the red emergency button on the back of the device is pressed, user can deactivate the emergency alert by selecting the Cancel 911 option. A screen will appear with two options to choose from: (i) With Gateway Ack or (ii) Without Gateway Ack.

When With Gateway Ack is selected and confirmed, the cancellation message is queued in the Outbox to be transmitted. If the cancellation message is successfully transmitted and acknowledged by the Iridium gateway, the emergency mode ends, the emergency LED is turned off and the top bar turns from red to black.
When Without Gateway Ack is selected and confirmed, the cancellation message is queued in the Outbox to be transmitted. The emergency mode ends immediately, the emergency LED is turned off and the top bar turn from red to black.
Powering the device off will not cancel the emergency mode. User MUST select Cancel 911 option to cancel emergency.
