public class Dtm : NmeaMessage, IEquatable<NmeaMessage>Remarks
This sentence is used to define the datum to which a position location and geographic locations in subsequent sentences, is referenced. Latitude, longitude and altitude offsets from the reference datum, and the selection of reference datum, are also provided.
The datum sentence should be transmitted immediately prior to every positional sentence (e.g., GLL,
BWC, WPL) that is referenced to a datum other than WGS84, which is the datum recommended by IMO.
For all datums the DTM sentence should be transmitted prior to any datum change and periodically at intervals of not greater than 30 seconds.
