 Float: Communication has been
established, but ambiguities have not been
resolved.
 StarFire: Position has been resolved.
Accuracy at the centimeter/decimeter level
 RTK Extend: Communication from Base
Station has been lost, coasting on StarFire
corrections.
 Fixed: Position has been resolved.
Accuracy at the centimeter level, more or
less.
• Satellites: The number of satellites in radio
communication.
• HSDV - Horizontal Standard Deviation and VSDV
– Vertical Standard Deviation: Indications of the
precision, not the accuracy, of the solution.
• The Dilution of Precision (DOP) indicates the
geometry of the satellites with respect to the
solution for the Horizontal Position (HDOP),
Vertical Position (VDOP), 3 Dimensional Position
(PDOP), Time (TDOP), and Position and Time
(GDOP). Generally, a PDOP of 4 or less is
preferred. A minimum of 5 satellites are required
to obtain a moving RTK solution and a minimum
of 4 are required to maintain the solution with an
acceptable PDOP.
3. Tap the Position tab to view the current position
and status of the GPS receiver (see Figure 46).
