  • Page 5: Introduction

    1 Introduction 1.1 Overview The TISTAR25 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.

  • Page 6: Receiver Operation

    The TISTAR25 incorporates a proprietary algorithm to compensate the effect of satellite constellation change, and maintains an accurate smooth estimate of the receiver’s position, velocity, and heading. Deluo Electronics http://www.deluo.com...

    1, 2, 3, and 9, position accuracy of less than 5 meters can be achieved. RXD1, pin-8 of the 10-pin Molex connector shown in figure 2, or pin-11of the 16-pin header shown in figure 3,is used as the DGPS input. Differential correction is applied automatically when the correction data is received at 9600baud. Deluo Electronics http://www.deluo.com...

  • Page 12: Software Interface

    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. The default receiver protocol is 4800baud, 8 data bits, 1 stop bit, and none parity.

    4.3 Data Logging In applications where the GPS receiver reported position, velocity, and time needs to be logged, the TISTAR25 supports logging capability directly by storing the data in the on-board memory. The logged data may be retrieved later. The logged information consists of: GPS time (WNO, TOW), with 1 second resolution.
