The following paragraphs briefly describe the major features of the GPS140HR. A more
detailed discussion is included in Chapter 4 (Hardware description) The boards
installation is described in Chapter 2 (Board Installation).
GPS receiver
The GPS140HR Global Positioning System (GPS) board uses for the satellite signal
reception data processing a miniature OEM GPS receiver module specially
designed for the most demanding applications. This low power receiver outputs
ASCII-character based NMEA-0183 data protocol or alternatively a binary message
protocol format. The used data protocol can be selected with a jumper. Special
features of the GPS receiver include 12 channel parallel-tracking channels and a fast
acquisition and reacquisition response. Powerful algorithms ensure reliable
operation in dense vegetation or in urban canyon environments.
