1. Introduction 1.1 Overview The HOLUX GR-212 Smart GPS Receiver is a total solution GPS receiver, designed based on SiRF Star II Architecture. This positioning application meets strict needs such as car navigation, mapping, surveying, security, agriculture and so on. Only clear view of sky and certain power supply are necessary to the unit. It communicates with other electronic utilities via compatible dual-channel through RS-232 or TTL and saves critical satellite data by built–in backup memory. -

The default communication parameters for DGPS Input are 9600 baud, 8 data bits, stop bit, and no parity. Position accuracy of less than 5 meters can be achieved with the GR-212 by using Differential GPS (DGPS) real-time pseudo-range correction data in RTCM SC-104 format, with message types 1,2, or 9. As using DGPS receiver with different communication parameters, GR-212 may decode the data correctly to generate accurate messages and save them in battery-back SRAM for later computing. - Page 12 HOLUX Bahrain – Ain el ABD 1970 International Data5.dat Bangladesh Everest 1830 Data6.dat Bolivia South American 1969 Data8.dat Botswana – ARC 1950 Clarke 1880 Data7.dat Brazil South American 1969 Data9.dat Brunel, East Malaysia Everest (Sabah & Sarawak) Data37.dat Canada – North American 1983 GRS 1980 Data10.dat...
