 OUTDOOR FUNCTIONALITY TESTS
– Outdoors cannot be simulated using GNSS Toolbox
– Satellites tracking
– Raw data logging – Has this option been licensed and is there
sufficient memory?
– Ground truth against known data – Does the computed position
appear correct?

 DATA COLLECTION
– Advice
 Software activation codes require the user to put the MobileMapper 6
into suspend mode or the code will be lost. With that task done once,
it can be powered on and off without losing the code.
 Use MobileMapper Today to set the clock every time it is turned on to
ensure that the clock is set properly before using MobileMapper
Field. It is the first clue that the MobileMapper 6 is ready for work.
Manually setting the clock does not ensure that the clock is set
properly.
 Good PDOP does not ensure good accuracy. Consider the quality of
the GPS signal. One customer who complained about accuracy sent
photos showing the receivers lying on the ground. Signals bouncing
off the ground are multipath.

 DATA COLLECTION (Continued)
GIS Post-Processing - Technical Presentation - September, 2010
– Advice (Continued)
 Do not expect CORS reference data on the same day of recording.
 Accuracy has as much to do with the 10 minutes before and after the
feature was recorded as it does the ten seconds spent recording a
point feature.
– Common mistakes and things you should NOT do:
 Raw data recording begins before the clock is set or before there is a
stable DGPS solution.
 Raw data recording is halted between feature mapping resulting in
dozens of tiny raw data files, none of which will process properly.
 Raw data recording of such short duration that it will not process.
Many of these contain ephemeris files too tiny to have recorded the
current ephemeris. Good rule of thumb is that a file less than 20
minutes long is wasted effort.
 Feature mapping that begins within seconds of starting the raw data
recording.
 Put receiver in pocket while walking between features to be logged..
