Internal GNSS ‘GPS’
RD8200SG locator has an internal GNSS module. When
internal GPS is enabled, it will automatically try to “lock”
onto a number of satellites as soon as the RD8200SG unit
is turned on.
The time required for the GNSS module to lock onto the
GNSS system varies depending on the length of time that
has passed since the last time the locator was used, and
on the presence of obstacles (like high buildings, trees,
etc.) that obstruct sight to the sky.
If the unit has not been used for several days the time to
first fix may take up to several minutes.
The RD8200SG locator display provides a number of
icons indicating the presence of an internal and active
GNSS and when this has locked to the GNSS system, the
quality of the signal received or numbers of satellites
received.
The accuracy of the GNSS module is affected by the
number of satellites received and best accuracy is only
reached when the signal quality is at its maximum.

The LCD GNSS operation icons provide visual information
about the status of the internal GNSS module:

RTK Fix
RTK fix means the GNSS accuracy is in the highest
precision mode and is suitable for taking points
The exact accuracy can be found on the mobile app (app
dependent).
This is visualized on the locator with a solid LED just
above the screen.
RTK Float
RTK float means that it is using correction data, but has
not moved to the highest precision mode yet. Only take
points in Float when Fix cannot be obtained. The exact
accuracy can be found on the mobile app (app
dependent).
This is visualized on the locator with a flashing LED just
above the screen.
RTK Off
The RD8200SG is not using correction data. This could
indicate an error in the NTRIP settings.
The LED above the screen is off.
