Survey Status Screen
The Survey Status screen provides information on the status of the survey during the
data collection period. From this screen, you can monitor the following observation
quality indicators:
•
Remain - The Remain field displays the amount of time remaining in the current
data point. The Remain field will count down beginning from the value of the
time-on-site field set in the Point Attribute screen.
•
#Sats - the #Sats field displays the current number of healthy satellites above a 10-
degree elevation being logged into memory. Periods of low satellite number will
require more data to be collected for a successful observation. This can be a good
indicator of the effect of obstructions at the survey site at any given time during
data collection.
•
PDOP - the PDOP field displays the PDOP value at any given time, computed
from all observed healthy satellites above a 10-degree elevation. Periods of high
PDOP will require more data to be collected for a successful observation. This can
be a good indicator of the effect of obstructions at the survey site at any given time
during data collection.
In addition to the survey status information, the
Survey Status screen also presents
the same power and memory status displays found on the
Satellite Status screen.
