Module twisted.protocols.gps.nmea

NMEA 0183 implementation

Maintainer: Bob Ippolito

The following NMEA 0183 sentences are currently understood: 
   GPGGA (fix)
   GPGLL (position)
   GPRMC (position and time)
   GPGSA (active satellites)
The following NMEA 0183 sentences require implementation: 
   None really, the others aren't generally useful or implemented in most devices anyhow
Other desired features: 
   - A NMEA 0183 producer to emulate GPS devices (?)
Classes
NMEAReceiver This parses most common NMEA-0183 messages, presumably from a serial GPS device at 4800 bps

Exceptions
InvalidChecksum  
InvalidSentence
