Class Variable	INVALID_FIX	The fix is invalid.
Class Variable	GPS_FIX	There is a fix, acquired using GPS.
Class Variable	DGPS_FIX	There is a fix, acquired using differential GPS (DGPS).
Class Variable	PPS_FIX	There is a fix, acquired using the precise positioning service (PPS).
Class Variable	RTK_FIX	There is a fix, acquired using fixed real-time kinematics. This means that there was a sufficient number of shared satellites with the base station, usually yielding a resolution in the centimeter range. This was added in NMEA 0183 version 3.0. This is also called Carrier-Phase Enhancement or CPGPS, particularly when used in combination with GPS.
Class Variable	FLOAT_RTK_FIX	There is a fix, acquired using floating real-time kinematics. The same comments apply as for a fixed real-time kinematics fix, except that there were insufficient shared satellites to acquire it, so instead you got a slightly less good floating fix. Typical resolution in the decimeter range.
Class Variable	DEAD_RECKONING	There is currently no more fix, but this data was computed using a previous fix and some information about motion (either from that fix or from other sources) using simple dead reckoning. Not particularly reliable, but better-than-nonsense data.
Class Variable	MANUAL	There is no real fix from this device, but the location has been manually entered, presumably with data obtained from some other positioning method.
Class Variable	SIMULATED	There is no real fix, but instead it is being simulated.

Inherited from _ConstantsContainer (via Values):

Method	__new__	Classes representing constants containers are not intended to be instantiated.
Class Method	lookupByName	Retrieve a constant by its name or raise a `ValueError` if there is no constant associated with that name.
Class Method	iterconstants	Iteration over a `Names` subclass results in all of the constants it contains.
Class Variable	_constantType	Specified by a `_ConstantsContainer` subclass to specify the type of constants allowed by that subclass.
Class Variable	_enumerants	A `dict` mapping the names of constants (eg `NamedConstant` instances) found in the class definition to those instances.
Class Method	_constantFactory	Construct the value for a new constant to add to this container.
