Note:
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, then if that factor is not met the
solution will be marked as invalid.
