1. Introduction 1.1 Overview The HOLUX GR-211 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. - Page 6 HOLUX 2) Update rate: 1 second. 3) Acquisition time Reacquisition 0.1 sec., averaged Hot start 8 sec., averaged Warm start 38 sec., averaged Cold start 45 sec., averaged 4) Position accuracy: A) Non DGPS (Differential GPS) Position 5-25 meter CEP without SA Velocity 0.1 meters/second, without SA...

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-211 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-211 may decode the data correctly to generate accurate messages and save them in battery-back SRAM for later computing. - Page 16 HOLUX European 1950 – Eastern Regional Mean International Data16.dat European 1950 – Egypt International Data17.dat European 1950 – Finland, Norway International Data18.dat European 1950 – Greece International Data19.dat European 1950 – Iran International Data20.dat European 1950 – Italy (Sardinia) International Data21.dat...
