GPS Receiver

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 miles above the Earth.

They are continuously monitored by ground stations 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.

The satellites are positioned so that we can receive signals from six of

them nearly 100 percent of the time at any point on Earth. You need that

many signals to get the best position information. Satellites are equipped

with very precise clocks that keep accurate time to within three

nanoseconds- that's 0.000000003, or three billionths of a second. This

precision timing is important because the receiver must determine

exactly how long it take s for signals to travel from each GPS satellite.

The receiver uses this information to calculate its position.

Although GPS was designed for military use, many thousands of civi

lians make use of it. The satellites actually broadcast two signals, one is

only formilitary use, and one 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 avariety of fields besides providing

navigation for vehicles on the sea, in the air and on the ground. GPS

applications also include keeping track of where afleet of trucks, trains,

ships or planes are and how fast they are moving; directin gemergency

vehicles to the scene of an accident; mapping where a city's assets are

located ; and providing precise timing for endeavors that require large-

scale coordination.

HI-203E is a GPS receiver with PS/II mini-DIN

interfaces and built-in active antenna for high

sensitivity to tracking signal. HI-203E is well suited

to system integration and users who use any kinds of

mobile devices, such as, PDA, notebook PC, Tablet PC, etc.

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 PDA or

other type of handheld PC running with suitable mapping

and routing software for navigation.

INTRODUCTION

1.1 OVERVIEW

The HI-203E GPS Receiver is intended for use in a wide range of

applications. The receiver simultaneously tracks up to twelve satellites,

provides accurate satellite positioning data with fast time-to-first-fix

(TTFF) and low power consumption. It is designed for high performance

and maximum flexibility in a wide range of applications including mobile

asset tracking, in-vehicle automotive guidance, location sensing,

telematics and so on. The highly integrated receiver achieves high

performance, minimizes board size and power consumption

requirements. The HI-203E is designed to withstand harsh operating

environments; however, it should be used inside an enclosure as a part

of the application product designed by the system integrator.

1.2 FEATURES

The HI-203E GPS receiver offers following features:

•T welve parallel tracking channels

•F ast TTFF and low power consumption

•Compact design suitab le for applications requiring small space

•On-board rechargeab le battery sustained real-time clock and memory

for fast satellite acquisition during power-up

•High accur acy one-pulse-per-second output

•Suppor ts NMEA-0183 protocol

•Full na vigation accuracy achievable with Standard Positioning Service

•Optimiz ed for navigation in urban-canyon environments

•A utomatic cold start with no user initialization required

SECTION 2

RECEIVER OPERATION

Upon power up, after initial self-test has completed, the HI-203E will begin

satellite acquisition and tracking process. Under normal open-sky condition,

position-fix can be achieved within approximately 45 seconds (within 15

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.

The receiver uses the latest stored position, satellite data, and current

RTC time to achieve rapid GPS signal acquisition and fast TTFF. If the

receiver is transported over a large distance across the globe, cold-start

automatic-locate sequence is invoked. The first position fix may take up

to five minutes searching the sky for the GPS signal. The acquisition

performance can be improved significantly if the host initializes the

receiver with a rough estimate of time and user position.

As soon as GPS signal is acquired and tracked, the HI-203E 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-203E will perform 3D navigation when four or more satellites are

tracked. When three or fewer satellites are tracked, altitude-hold is enabled

using the last computed altitude and 2D navigation mode is entered.

With signal blockage or rising and setting of the satellites, where a

change in satellite constellation used for position fix occurred, large

position error may result. The HI-203E incorporates a proprietary

algorithm to compensate the effect of satellite constellation change, and

maintains an accurate smooth estimate of the receiver position, velocity,

and heading.
