b) Age of Differential Data
For GPS differential dat a: This value is the average of the most recent
differential corrections in use. When only RTCM SC104 Type 1 corrections are
used, the age is that of the most recent Type 1 correction. When RTCM SC104
Type 9 corrections are used solely, or in combination with Type 1 corrections, the
age is the average of the most recent corrections for the satellites used. Null field
when Differential GPS is not used.
For GLONASS differential dat a: This value is the average age of the m
recent differential corrections in use. When only RTCM SC104 Type 31
corrections are used, the age is that of the most recent Type 31 correction. W
RTCM SC104 Type 34 corrections are used solely, or in combination with Type
satellites used. Null field when differential GLONASS is not used.
