Product Overview

• The GEO Trigger device targets tracking of high-value packages in primarily outdoor environments.  In an “active” mode in which the device is moving, tracking GPS location, and sending location updates over the GSM cell radio, the device is expected to last 3-15 days depending on reporting rate. The on-board accelerometer will be used to enable a “passive” mode as well.  When the device isn’t moving, it will turn off its GSM and GPS subsystems and extend the battery life to weeks or months. 

• The GEO Trigger device communicates to the  ASPS Information Management Bureau via a direct socket connection over the GSM cell phone network and internet cloud.  In this respect, a GEO Trigger reports readings or receive queued commands whenever necessary via a direct data link into the backend servers. Also, the backend servers can inform the device to call in via an SMS text message page, which will be received whenever the GEO Trigger device is attached to the GSM network.  The achievable range for this radio is miles.  The GEO Trigger device also includes a second radio to form a potential uWLAN (ultra-low power Wireless Local Area Network) radio that will allow it to communicate with other GEO Trigger devices.  The achievable range for this radio is 100s of feet.

•  The GEO Trigger contains a rich suite of sensors for tracking the quality of shipments as well as alarm conditions.  These sensors include cold chain monitoring sensors (temperature and humidity), quad-positioned light sensors (as a proxy for tamper detection), a digital three-axis accelerometer (for understanding motion/rest periods, impact events, and box orientation), a pressure sensor (as a component of the airplane algorithm) and of course GPS (for absolute Location data).  As part of the uWLAN subsystem, a low-power integrated microcontroller with appropriate firmware is provided to drive these sensors and achieve optimal power management of the entire device.  This is performed through a careful arrangement of both interrupt and sampling algorithms, depending on sensor type.
