Get the NMEA HDOP(relative accuracy) from the NMEA $GPGGA sentence
Horizontal Dilution of Precision (HDOP) is returned in the $GPGGA NMEA sentence .
To read HDOP value,
- Using the AT Command Tester tool, parse the $GPGGA NMEA sentence from the GPS device
- The NMEA HDOP value is automatically parsed and displayed in the device.
- The HDOP value can be 1 or less. When HDOP value is 1, the precision is good.
