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).
