NMEA support

The router supports the National Marine Electronics Association NMEA-0183 compatible (V2.3) standard of
sending GPS data.
The standard includes "sentences" used to identify the type of data being sent and therefore defines the way the
data is interpreted.
The GPS related sentences supported by the NTC-223 are:
GPGGA – Global Positioning System Fix Data, Time, Position and fix related data for a GNSS receiver
GPRMC – Recommended Minimum data for GPS
GPGSV – Detailed satellite data
