I need to use data NMEA standard from $GPGGA, $GPRMC and $GPVTG. Could You tell me how many characters are max possible in:
- Horizontal dilution of precision (HDOP);
- Altitude in meters according to WGS84 ellipsoid ;
- Height of geoid (means sea level) above WGS84 ellipsoid;
- Speed over ground in km/h;
I need to know, because data will write to flash memory :). Thanks for help.
it depend on the exact type of GSM module you want to use in your project ， since the different GSM module is based on the Platform
thanks for your understanding
Hi, ok - module which is used in project: MC60.
The same question is for: PDOP, VDOP, geoid separation, DGPS Age, DGPS Station ID and speed over ground in knots. Could You confirm - the checksum has always 1 bytes ? (Max. hex value 0xFF) Thanks for help.
for MC60 , I need to submit one ticket internally , thank for your undstanding
I got feedback from R&D ,all NEMA data of MC60 comply with the NEMA standard
