• Epochs
- the number of epochs in the common data time interval.
• Orbit
- only Broadcast ephemeris is used for obtaining RTK GPS
observations.
• GPS Satellites
- the number of GPS satellites. For RTK GPS
observations, it is the maximum number of common
GPS satellites observed by the base and rover in the common
interval.
• GLONASS Satellites
- the number of GLONASS satellites. For
RTK GPS observations, it is the maximum number of common
GLONASS satellites observed by the base and rover in the
common interval.
• PDOP
- the average value of total position dilution of precision
(PDOP) for common epoch intervals. PDOP is equal to the
square root of the sum-of-squares HDOP and VDOP.
• HDOP
- the average value of position dilution of precision in the
horizontal plane (HDOP) for common epoch intervals.
• VDOP
- the average value of position dilution of precision in the
vertical plane (VDOP) for common epoch intervals.
