  • Page 2 General description of what GPS is and how it works. GPS (Global Positioning System) is the o n l y system today able to show you your exact position on the Earth anytime, in any w e ather, anywhere. GPSsatellites, 24 in all, orbit at 11,000 nautical milesabove the Earth.They are continuously monitored by ground stations located worldwide.

  • Page 4 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.

    3.4 O NE-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.

  • Page 11: Software Interface

    SECTION 4 SOFTWARE INTERFACE This section describes the details of the serial port commands through which the HI-203E 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.

  • Page 12: Default Values

    HDOP: 8 Receiver Operating Mode: Normal Mode (without 1PPS) Commands can be issued to the HI-203E to change the settings of the receiver. The new settings will remain effective on next power-on as long as the on-board rechargeable backup battery is not discharged. After the backup battery is discharged, factory preset default settings...
