Scope
This document sets forth the basic technical requirements and feature set for the ion
tracking device.
Description
The Arrow Tracker is a self contained, expandable, integrated commercial grade vehicle
tracking device that uses GPS satellite location in combination with a quad band
GSM/GPRS cellular radio connection to report that location. ion is optimized for
reliability, cost and size. However, it remains highly flexible and capable of addressing
diverse and specialized requirements through a novel expansion arrangement.
All antennas including the GPS patch and GSM helical antenna are internal to the device.
Data reporting can be initiated by a command center or by the tracker itself via
GSM/GPRS, SMS or UDP pathways.
The Arrow is unique in that it is intrinsically expandable. A screw fastened expansion
door secures SIM card access as well an expansion connector and daughter board cavity.
This port supports small integrated daughter boards with features such as motion
detection, acceleration measurement or radio expansion through standards such
Bluetooth, Zigbee or WiFi.
The Arrow also supports functional expansion by a side mount adapter. This adapter
supports addition of physically large devices such as very large capacity batteries.
The Arrow is based on chip level design as opposed to using a module with an external
processor. The application software executes on the base level Central Processing Unit
(CPU) under direct Operating System (OS) control. This approach provides a much more
reliable, lower power and faster response than module/processor architectures. Unlike in
common module/processor based designs; the ion design allows direct operating system
access by the application, thus mitigating the need for a redundant external processor.
For added redundancy against system lockup, a physically separate, dedicated watchdog
chip oversees the ion system operation. If the system does not maintain the watchdog
chip through programmed reporting, the system power is cycled and a new satellite and
cellular connection is established.
The Arrow Tracker can be provisioned for UDP and SMS data services for both
application command and data transactions within the 850, 900, 1800 and 1900 MHz
GSM bands. Network provisioning is done with standard SIM cards. For added
safeguard against network connection loss, a hardware ion endpoint reboot can be
initiated by simply calling the provisioned phone number from a previously established
Caller ID (CID).
Flexible I/O includes 2 bidirectional General Purpose Input Output (GPIO) ports that can
also be assigned as a software Universal Asynchronous Receiver Transmitter (UART)
port. A separate dedicated UART port is provided for general use as well as development
and programming support. A high current relay drive is provided for starter motor relay
control or general purpose drive (current sink only).

The power input, ground and GPIO signals that are present on the main 8 pin external
vehicle connector are also available on the 8 pin internal expansion connector. On the
internal connector, there is also a unique battery supply pin that supports connection of a
rechargeable battery.
Over The Air (OTA) program updates are supported through Firmware Over The Air
(FOTA) protocol. This server based update system is licensed from HP.
All inputs are electrically hardened against overvoltage and over current conditions
present in automotive environments. This includes transient electrical noise and Electro
Static Discharge (ESD). The power input is further protected against over current with
an internal, self resetting fuse.
The Arrow enclosure and its features are secured using M2 sized metal fasteners for
rugged mechanical performance. The daughter board expansion and vehicle interface are
achieve through robust, commercial grade, pin to wire header connections (in contrast
with leaf contacts commonly used in cell phones and other portable non-industrial
systems).
The Arrow is physically disguised to appear to an untrained observer to be a nondescript
part of the cabling system. It is a small black box with unremarkable features. Two LED
status indicators are provided to verify correct installation and initial operation. A unique
feature extinguishes those status indicators 24 hours after an initial power up sequence.
This feature further conceals the ion Tracker from untrained parties wishing to defeat its
operation. The status indicators resume normal operation after the primary power has
been removed for any length of time. This allows for maintenance to be initiated by
simply disconnecting and then reconnecting power. This feature may be disabled as a
factory option.
The Arrow Tracker uses a simple cabling arrangement and supports splicing into an
OBDII extension for power. Connection to the vehicle is made through a 3mm pitch
rectangular header connection common to the automotive market.
As with all GPS location devices, the ion should be installed in a vehicle such that it has
an unobstructed view of the sky during normal operation. Double sided foam tape can be
used to secure the surface not facing the sky if needed.

Software Architecture
The application software resides in system flash memory and operates directly under
control of the native OS. Arrow does not use an external applications processor.
Structure
Figure 2 shows a high level block diagram of the basic architecture. The OS is closely
knit with a debugger allowing for code development, maintenance and updates over the
serial debug port. The boot loader provides control over all code and configuration
memory. The watchdog is a dedicated hardware device that will issue a hardware reset to
the unit in conjunction with a power cycle operation if it is not maintained by a periodic
ping from the application program.

Features
Arrow acts like a GSM modem and responds to AT commands issued to it from either a
physical serial port connection or to AT commands issued to it through SMS or a UDP
connection.
With regard to text messages, ion “reads” all of its own text messages and tries to
interpret each message as an AT command. SMS text may be sent to an endpoint
through a CSD or GPRS connection interchangeably.
Key superset functions outside that of typical GSM/GPRS modems are required to
support intrinsic ion Features. These include:
Automatic field lockup recovery
o Dedicated hardware watchdog with power and reset cycle
o GSM Circuit Switched Data (CSD) commands
Hard reset
Restore factory defaults
Instantiate code download using FOTA
Set Caller ID (CID) qualifier
Specialized GPS functions including
o GPS data reporting
o GPS module status reporting
o GPS power control
o Setup and monitor geographic fences
Device initiated UDP reporting
o Recurring schedule event
o Low battery condition
o Change in GPIO state
o Report record queue
o User defined IP addresses
o Geographic fence violation

The two status LEDs directly convey the status of the GSM and GPS subsystems as
described in the table. Indirectly, through their absence of a valid indication, they also
provide power and operational status. These LEDs are color coded and located as shown
in Figure 7.

-- Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
-- Consult the dealer or an experienced radio/TV technician for help.
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions:
(1) This device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.
Changes or modifications not expressly approved by the party responsible for compliance could
void the user's authority to operate the equipment.
RF Exposure Warning Statements:
The antenna(s) used for this transmitter must be installed to provide a separation distance of at
least 20 cm from all persons during the normal operations.
IC STATEMENT
This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject
to the following two conditions: (1) this device may not cause interference, and (2) this device
must accept any interference, including interference that may cause undesired operation of the
device.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio
exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne
