User manual HAICOM HI-202E

[. . . ] GPS applications also include keeping track of where a fleet 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. 3 1. HI-202E Series Introductions HI-202E is a GPS receiver with USB interfaces and built-in active antenna for high sensitivity to tracking signal. HI-202E 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. [. . . ] If the receiver is transported over a large distance across the globe, cold-start automaticlocate sequence is invoked. The first position fix may take up to 50 sec 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. 8 As soon as GPS signal is acquired and tracked, the HI-202E 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-202E 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-202E 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. 9 2.
