HI-204III-USB WATERPROOF Ultra High Sensitive USB GPS Receiver 1
General description of what GPS is and how it works. GPS (Global Positioning System) is the only system today able to show you your exact position on the Earth anytime, in any weather, anywhere. GPS satellites, 24 in all, orbit at 11,000 nautical continuously miles monitored above by the ground Earth. They stations are located worldwide. The satellites transmit signals that can be detected by anyone with a GPS receiver. Using the receiver, you can determine your location with great precision.
Although GPS was designed for military use, many thousands of civilians make use of it. The satellites actually broadcast two signals, one is only for military use, and the other can be used by both military and civilians. Since GPS is passive (you only need to receive the signal), there are no restrictions on who can use the signal available to civilians. GPS technology can be used in a variety of fields besides providing navigation for vehicles on the sea, in the air and on the ground.
1. HI-204III-USB Series Introductions HI-204III-USB is a GPS receiver with USB interfaces and built-in active antenna for high sensitivity to tracking signal. HI-204III-USB is well suited to system integration and users who use any kinds LaptopPC. It satisfies a wide variety of applications for car navigation, personal navigation or touring devices, tracking and marine navigation purpose. Users can simply plug it into a LaptopPC running with suitable mapping and routing software for navigation. 1.
USB port For notebook PC use: HI-204III-USB connect with a LaptopPC USB port.
SECTION 1 INTRODUCTION 1.1 OVERVIEW Fast Acquisition Enhanced Sensitivity 20 Channels “All-In-View” Tracking GPS Sensor Module The receiver continuously tracks all satellites in view and provides accurate satellite positioning data. The HI-204III-USB is optimized for applications requiring good performance, low cost, and maximum flexibility; suitable for a wide range of OEM configurations including handhelds, sensors, asset tracking, PDA-centric personal navigation system, and vehicle navigation products.

SECTION 2 RECEIVER OPERATION Upon power up, after initial self-test has completed, the HI-204III-USB will begin satellite acquisition and tracking process. Under normal open-sky condition, position-fix can be achieved within approximately 35 seconds (within 10 seconds if valid ephemeris data is already collected from recent use). After receiver position has been calculated, valid position, velocity and time information are transmitted through the on board serial interface.
As soon as GPS signal is acquired and tracked, the HI-204III-USB will transmit valid navigation information through its serial interface. The navigation data contains following information: • Receiver position in latitude, longitude, and altitude • Receiver velocity • Time • DOP error-magnification factor • GPS signal tracking status The HI-204III-USB will perform 3D navigation when four or more satellites are tracked.

3.2 ONE-PULSE-PER-SECOND (1PPS) OUTPUT The one-pulse-per-second output is provided for applications requiring precise timing measurements. The output pulse is 1usec in duration. Rising edge of the output pulse is accurate to +/-1usec with respect to the start of each GPS second. Accuracy of the one-pulse-per-second output is maintained only when the GPS receiver has valid position fix. The 1PPS output is always generated when the GPS receiver is powered-on.
As long as enough satellite signals are received to generate valid position fixes, the 1PPS output remains synchronized to the GPS second, and the 1PPS Valid Signal remains active. If signal blockage prevents the receiver from generating valid position fix, the 1PPS output will drift away from the GPS second and the 1PPS Valid Signal will become inactive.
SECTION 4 SOFTWARE INTERFACE This section describes the details of the serial port commands through which the HI-204III-USB is controlled and monitored. The serial port commands allow users to set the receiver parameters, configure output message type, and retrieve status information. The baud rate and protocol of the host COM port must match the baud rate and protocol of the GPS receiver serial port for commands and data to be successfully transmitted and received.
