Confidential Preliminary – Subject to Change 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.
Confidential Preliminary – Subject to Change 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.

Preliminary – Subject to Change Confidential 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 L o a d e r B o o t 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.
Preliminary – Subject to Change Confidential 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.
