1. TRACKPACK
TrackPack is a fully self contained, highly reliable and environmentally
hardened global satellite based tracking device capable of determining
location using GPS and reporting that location over a low earth orbit (LEO)
satellite network using the AeroAstro patented SENS CPDMA™ satellite
communications system to provide a robust, easy to use asset tracking
solution.
The TrackPack is powered by internal primary batteries and require no wires
or harnesses for use. The TrackPack features a wireless configuration system
using a simple Graphical User Interface (GUI) application and a wireless USB
Dongle. Users can configure TrackPack without cables or lengthy connection
procedures. The Wireless USB Dongle can communicate with multiple
TrackPacks at the same time thus allowing users to configure more than one
TrackPack simultaneously.
The TrackPack communicates data via the Globalstar Simplex Data Service.
This satellite service utilizes low power, one-way transmitters to relay data
from locations globally to a back office server accessible over the internet
through a secure connection. The use of one-way, simplex satellite
communications is a proven, reliable method. This feature is augmented by a
rich configuration capability that enables the TrackPack to automatically
detect situations where a data update is desired, such as start and stop or
while in motion.
This Users Manual describes how the TrackPack is configured and the protocol
for on-air data payload and internet XML packets. This document provides a
generalized overview only. Consult Comtech AeroAstro for more details and
options of relaying data.

1.2 Mechanical
The TrackPack is a compact assembly containing a GPS receiver, satellite
transmitter, antennae and batteries. The device is a small outline and low
profile. The TrackPack is a fully contained tracking device suitable for
extended exposure to outdoor and industrial environments. It is 5 inches
length, 1.7 inches wide, and 0.82 inches in height. The TrackPack device is
fully enclosed and hermetically sealed to ensure no moisture ingress.
1.3 Electrical
The TrackPack operates using a series of lithium iron disulfide batteries. The
Device uses 4.5V for all battery powered operation.
Comtech AeroAstro, Inc 6013-GD-00001 4
2. GETTING STARTED
TrackPack is designed to allow users to easily
deploy a single or multiple devices. The TrackPack
supports over-the-air configuration provided that
the devices are within 60 ft from the wireless
configuration dongle. Simply attach the Wireless
USB configuration dongle and scan for TrackPacks
that are in the range of the configuration tool.
2.1 Configuration Software Installation
TrackPak is wirelessly configured using a USB dongle and a Simple Graphical
User Interface (GUI) software. The Configuration Kit includes a the USB
dongle and a CD-ROM which contains the TrackPack configuration software
and the drivers needed for the USB dongle. Installation instructions are
described below:
Wireless USB Communicator:
1. Insert the TrackPack
Configuration CD. You can also
download the drivers ahead of
time using the CD-ROM or
through the Customer Support
Center.
2. Insert USB dongle, the
Hardware Wizard will pop up
and you will have the option to install the Drivers automatically or
install from a specific location. Select the “Install software
2
Comtech AeroAstro, Inc 6013-GD-00001 5
automatically” option. The Wizard will detect where the Drivers are
located (in CD-ROM or Saved in Hard drive).
NOTE
If this option does not work, you can select the “Install from
Specific location” and point the wizard to the CD-ROM or the
location where the driver has been saved.
GUI Installation:
1. Download the latest TrackPack Configuration software from the CD-
ROM
2. Run by double-clicking the TrackPack
configuration software.
The Configuration Software and drivers can be downloaded via the Customer
Resource center (www.sensservice.com/senssupport). You will need to login
using your AssetView administrative credentials.
2.2 Connecting the Device
Insert your wireless USB Dongle and run the TrackPack Configuration Tool.
The USB Dongle LED will provide feedback when the
Dongle is active. The Dongle LED is a steady green
light when the Dongle is connected to a PC and will
blink when it is actively searching or communicating
with a TrackPack.1
1 Note: Satcom and wireless radio and are not capable of transmitting simultaneous
LED Feedback
Comtech AeroAstro, Inc 6013-GD-00001 6
The TrackPack unit and the USB Dongle communicate securely using a
passkey. Pre-configured units will only communicate with the USB dongle if
the appropriate passkey has been entered.
Using the Configuration Tool, Select the “Passkey” option located in the tool
bar.
Enter the passkey that is assigned to your account and press the “Use
this passkey” button.
To communicate with New Units (no Passkey)
Click the “Search for New Units” button. This will retrieve all units that
do not have a passkey assigned.
* Once you Press the Program Button. The Passkey entered in the
Passkey screen will be programmed in the unit.
To communicate with previously configured units:
Click the “Search for Units” button. This will retrieve units that have
the matching passkey.

for a more advanced set of configurations.
Comtech AeroAstro, Inc 6013-GD-00001 14
The Advanced Configuration begins by selecting the Message Parameters
located in the Messages Section.
These Messaging parameters control the number of repeat messages to be
sent within the selected minimum and maximum seconds for each unique
message. The Default parameter is set to 3 Tries for unique message
between 300 seconds to 600 seconds to ensure reliability of message success
rate. Given that not all applications require the same reliability or
requirements to send messages more quickly, this setting is user configurable
to suit several applications.
Users may select their Tries per message from 1 through 15. The Tries
minimum and maximum is also user configurable but will provide feedback
with the appropriate calculations.
The Channel Selection allows the user
to select which operating channel the
TrackPack will be. It is best to select
the “Allow TrackPack to Select a
Channel” radio button. The TrackPack
comes with Radio Astronomy Site
(RAS) Detection and will switch Channels once a RAS is detected.

5. MESSAGING PRIORITY
The TrackPack has 2 types of Location Message. These messages are
Standard Location message which is configured by the user to send in an
interval or a schedule mode and a Motion message which is configured by the
user to be sent based on motion sensitivity, attack and decay settings.
The Messaging priority is set to the Motion Message when this function is
enabled. The TrackPack will send standard location message (s) as
configured even with the motion sensor enabled. Once motion is detected,
the TrackPack will send the Motion message as a priority and will resume
Standard location message configuration.

APPENDIX E: MESSAGE FORMAT
TrackPack sends messages over the Globalstar satellite network in 16-btye
packets. Nine of the sixteen bytes are reserved for variable user data.
TrackPack employs three different message types: tracking (location) mes-
sage, configuration message, and status message. The user data format for
each message is listed as follows:
1. TRACKING MESSAGE
The tracking message is used to report location that is transmitted on a
schedule or interval. This type of message is also used to indicate if the mes-
sage was triggered by the Motion sensor. The Message Trigger will indicate
the following:
Schedule – Location messages
Motion Start – indicates that motion has started
Motion Stop – indicates that motion has seized.
