Hi all, I am trying to log data from a Haicom 204-E GPS device onto a PC (writing a program) and have two questions about the data. The output standard is in NMEA-0183 v2.20
I hooked it up to HyperTerminal and got the following output (repeating every second):
$GPGGA,085540.034,2731.7256,S,15304.5076,E,1,04,02.1,00057.8,M,38.4,M,,*7E $GPGSA,A,3,25,01,,,,,,20,,16,,,02.3,02.1,01.0*02 $GPGSV,2,1,08,25,43,143,31,01,45,142,31,13,07,257,,11,32,312,*77 $GPGSV,2,2,08,20,59,211,37,23,36,234,,16,40,055,36,47,56,132,*7E $GPRMC,085540.034,A,2731.7256,S,15304.5076,E,000.0,195.6,211004,011.2,E*77
The manual says that it supports GGA, GLL, GSA, GSV, RMC and VTG messages yet I don't see the GLL message there and that is the one I wish to pull the data from (I only want lat and long). It has enough satellites for a 3d-Fix.
My question is can I use the latitude and longitude data from the GGA or RMC message instead?
Additionally I noticed that there is a difference between the value there and the value displayed on the software that came with the unit. In a particular recorded instance: From hyperterminal: Longitude: 15304.4874E Latitude: 2731.7213S format: dddmm.mmmm ddmm.mmmm
From Boxed program: Longitude: 15308.8740 Latitude: 2738.2130 unknown format
I was thinking maybe they have a different format but I tried a few conversions and nothing seemed to match.
4 minutes is a large distance on the ground! Any help with this would be appreciated.
Cheers Marc
