1 HI-204E WATERPROOF GPS Receiver HI-204E WATERPROOF GPS Receiver.
2 General description of what GPS is and how it w orks. GPS (Global P ositioning System) is the only system today able to show you your exact position on the Ear th anytime, in any weather , anywhere. GPS satellites, 24 in all, orbit at 11 ,00 0 na uti cal mil es a bove t he E ar th .
3 Although GPS was designed f or militar y use, many thousands of civi lians make use of it. The satellites actually broadcast two signals, one is only formilitar y use, and the ther can be used b y both militar y and civilians.

6 1 . H I - 2 0 4E S e r i e s I n t r o d u c ti o n s HI-204E is a GPS receiver with PS/II mini-DIN interf aces and built-in activ e antenna for high sensitivity to tracking signal . HI-204 E is well suited to syste m integrat ion and users who use any kinds of mobile de vices, such as , PD A, notebook PC, T ab let PC, etc.
7 Optional Accessories: • PS/II to PDA connector and car charger • PS/II to DB9 adapting cable • PS/II to USB adapting cable HI-204E-XXXX (P ocket PC Plug) HI-204E-DB9 HI-204E-USB.
8 SECTION 1 INTRODUCTION 1.1 O VER VIEW F ast Acquisition Enhanced Sensitivity 12 Channel GPS Sensor Module The HI-204E is a compact all-in-one GPS module solution intended for a broad r ange of Original Equipment Manuf acturer (OEM) products, where fast and easy system integration and minimal de velopment risk is required.
9 Satellite-based augmentation systems, such as W AAS and EGNOS, are supported to yield improved accuracy . Both the L VTTL-level and RS232-le vel ser ial interface are provided on the interface connector . Supply voltage of 3.3V , or 3.8V~12V are suppor ted.
10 SECTION 2 RECEIVER OPERATION Upon power up, after initial self-test has completed, the HI-204E will begin satellite acquisition and tracking process. Under nor mal open-sky condition, position-fix can be achieved within appro ximately 35 seconds (within 10 seconds if valid ephemeris data is already collected fr om r ec en t us e) .
11 As soon as GPS signal is acquired and trac ked, the HI-204E will transmit valid navigation information through its ser ial interface . The navigation data contains follo wing information: • Recei.

15 3.3 ONE-PULSE-PER-SECOND (1PPS) OUTPUT The one-pulse-per-second output is provided f or applications requir ing precise timing measurements. The output pulse is 1usec in duration. Rising edge of the output pulse is accurate to +/-1usec with respect to the star t of each GPS second.
16 As long as enough satellite signals are received to generate valid position fixes , the 1PPS output remains synchroniz ed to the GPS second, and the 1PPS V alid Signal remains active .
17 SECTION 4 SOFTWARE INTERFACE Thi s sec tion de scr ibe s t he de tail s o f the se ria l p or t commands through which the HI-204E is controlled and monitored. The serial port commands allow users to set the receiver parameters, configure output message type, and retriev e status information.
