Buffered Serial Data Card

Abstract

NAVSTAR Global Positioning System (GPS) User equipments (UEs) send out navigation information in the form of blocks of serial data. The format and transmitting rate of the data varies between UEs. Several agencies within the Australian Department of Defense require the collection of GPS UE data. As a personal computer general purpose data logging card was not available commercially, it was decided to design and develop such a card to enable collection of data from any GPS UE. This card may be used to collect data from any source which transmits data at either RS232 or RS422 levels. This manual describes the operation of the Buffered Serial Data Card and the process of writing user software.
