1. Introduction
Combining both GPS and Bluetooth technologies, Flaircomm’s GPSBT560 receiver allows you to determine your
current geographic location and direction anywhere. It communicates in real-time with Bluetooth-enabled devices
such as PDAs, Smart Phones, Computers, and other devices to provide locations information for navigation
applications. This battery-powered portable device can be easily placed on the car or carried by the user.
1.1 Global Position System (GPS) Technology
The Global Positioning System (GPS) is a worldwide radio-navigation system formed from a constellation of 24
satellites and their ground stations. A GPS receiver is a device that calculates its location based on received satellite
information and could provide its geographic location information with accuracy up to few meters. The accuracy of
the receiver depends on the number of satellites in view and signal strengths received.
1.2 Bluetooth Technology
Bluetooth is an internationally standardized technology supporting short distance wireless communications. Any
two Bluetooth-compatible equipments, such as mobile phone, PDA, PC, headset, mouse, keyboards, printer, etc.
can wirelessly communicate with each other via Bluetooth connection. To ensure worldwide compatibility,
Bluetooth operates on the globally available ISM (Industrial Scientific and Medical) frequency band. Within 2.4
GHz and 2.48 GHz, Bluetooth transmits data up to either 10 meters (CLASS II mode) or 100 meters (CLASS I
mode) using 79 frequency hopping channels.
Though line-of-sight is not required, Bluetooth connections could be subject to interferences from obstructions such
as walls, human bodies, and other electronic devices. In addition, due to variations on product implementation, it is
likely that Bluetooth equipments from different manufactures have interoperability issues. In that case, you may
consult with manufactures to check product compatibility.
Note that, there could be some restrictions imposing on using Bluetooth devices in some countries. Please check
with your local authorities.
1.3 Intelligent GPS Tracking and Bluetooth Connecting (ITC) manager
GPSBT560 is designed with advanced power management scheme, the intelligent GPS Tracking and Bluetooth
Connecting (ITC) manager. The ITC manager automatically wakes up and goes to sleep depending on whether or
not the Bluetooth connection is on. Once a paired Bluetooth device moves in the Bluetooth range and connects to
the receiver, the ITC manager wakes up the GPS unit and commands it to start position tracking. Once a connected
device moves out of the Bluetooth range or is disconnected by the user, the ITC manager shutdowns unused
hardware components and commands the device entering into the sleeping mode. Thus minimizes GPSBT560’s
power consumption and extends working and standby time dramatically.
