Table 11.8-5: RMC Data Format

A valid status is derived from all the parameters set in the software. This includes the minimum
number of satellites required, any DOP mask setting, presence of DGPS corrections, etc. If the default
or current software setting requires that a factor is met, and then if that factor is not met the solution will
be marked as invalid.
