• PREPARATION (Continued)
• Licensing
• MobileMapper Office (PC) requires no license
• MobileMapper Field (MobileMapper 6) must be
  licensed with activation code
• Program will not open without license
• Post-processing for MobileMapper Field must be
  licensed with activation code
• Code requested when selecting Record raw data
  for post-processing box inside the Recording
  tab under the Options dialogue boxes

• 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)
• 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..
