Spectra Precision Survey Pro v4.6 GPS - Manual (Page 14)

Receiver Dynamics:
¾ Static on Occupy: will set the receiver to ‘static’ mode
for point occupations. When in static mode, the
receiver assumes no antenna movement and uses
advanced averaging techniques to compute the most
precise position possible.
¾ Dynamic
Always
will leave the receiver in ‘dynamic’
mode for point occupations.
Store GPS Raw Data:
¾ Lat, Lng, Ht will store an EP record in the .RAW file
for each point accepted.
¾ EP + Bl,CV will store an EP record, plus the raw base
line and variance covariance information in the .RAW
file (or .OBN file for Ashtech users)
¾ EP + Bl,CV + Rx Raw will store the EP,BL,CV records
in the .RAW file (or .OBN file for Ashtech users), and
send the station information to the observation file for
GPS post processing data collection.
¾ EP + Rx Raw will store an EP record in the .RAW file
and send the station information to the observation
file for GPS post processing data collection.
Accept Solution Quality and Criteria:
¾ Select to Accept either Fixed RTK only, or Code, Float,
or Fix
positions.
¾ Choose a measurement criteria. Any non-zero values
will be used to check positions before they are stored.
¾ If you want to automatically store points that meet
your criteria after five epochs of data collection, check
the Automatically accept data collection points box.
Epoch Averaging:
This setting controls how many epochs of data Survey Pro will
use to average the final position. It should usually be set to 1.
Note: Epoch Averaging should not be used when you Receiver
Dynamics
are set to Static on Occupy. With any current GPS
firmware, a receiver in static mode will use a least squares
technique to give a progressively more precise position with
each subsequent epoch. Epoch Averaging in Survey Pro is a
simple averaging technique intended for old firmware or
when you are set to Dynamic Always.
