Chapter 5. Logging Raw Data
Introduction
You can log raw data in two different ways:
• Standalone: You simply need to use the Log button to start
and stop raw data logging.
Later, you will however need to do the following manually:
1. Downloading phase: Rename the raw data files
collected on each site.
2. Post-processing phase: Manually correct all computed
elevations for the antenna height.
• Using FAST Survey: The Survey>Log Raw GPS function
allows you to fully control raw data logging. Using this
method offers three advantages:.
1. Antenna reduction is automatically performed during
post-processing because of the antenna height value
(from the receiver properties) stored in the raw data
files.
2. Ability to name the raw data file and insert time tags.
3. Ability to pause/resume data logging.
By default, raw data is logged to the receiver's internal
memory.
Using FAST Survey, you can change the storage medium
(internal memory or USB memory stick).
The choice of storage medium is then valid for both data
logging methods (standalone and using FAST Survey). If
"USB memory stick" is selected and no USB stick is
connected to the receiver, then no data logging will take
place.
In both data logging methods, the Raw Data Logging icon on
the General Status screen will start flashing when a raw data
file is open for logging.
