English If the period of continuous lock is less than 5 minutes, the SBAS-corrected position may be more accurate. When recording a job for post-processing, the receiver records GPS measurements the entire time the job is open - not just when you're recording data into a feature. Therefore, you do not need to record each feature for more than 20 minutes. Each feature has to be recorded during a portion of the job file where you maintained lock on the satellites for at least 20 minutes. If you open a job, open a point feature 19 minutes later, record the point feature for 60 seconds and close the feature and the job, the feature will be recorded during a period lasting 20 minutes and you should have sub-meter accuracy. For this reason, it is best to open the job as soon as you are in a position to maintain constant satellite lock and close it more than 20 minutes later. 68

If the period of continuous lock is less than 5 minutes, the
SBAS-corrected position may be more accurate.
When recording a job for post-processing, the receiver records
GPS measurements the entire time the job is open – not just
when you’re recording data into a feature.
Therefore, you do not need to record each feature for more
than 20 minutes. Each feature has to be recorded during a
portion of the job file where you maintained lock on the satel-
lites for at least 20 minutes.
If you open a job, open a point feature 19 minutes later,
record the point feature for 60 seconds and close the feature
and the job, the feature will be recorded during a period last-
ing 20 minutes and you should have sub-meter accuracy.
For this reason, it is best to open the job as soon as you are in
a position to maintain constant satellite lock and close it more
than 20 minutes later.
