 | Show Top "N" Rows - This controls how many of each
division is displayed in the Results Pane. It does not affect results that
are an average of a number of results. |
| Speed Units - this controls what units are displayed in the Results
Pane and Track Point Pane. |
| Smoothing Count - This option determines over how many points the
track point smoothing is performed in the Speed Graph when viewing the
Smoothed graph option (see the Graph Fields for details). This option does
not affect any other data displayed in the Speed Graph. The more points
chosen the smoother the speed curve. This is useful for results produced
from the Garmin GPS units that are very irregular. |
| Speed, Time, Distance and Lat/Long Precision - This options
determine the number of decimal points displayed in the appropriate
fields of Results and Track Point Panes. |
| Timezone Adjust - Set here the number of hours to adjust from UTC
time. Sydney is +10 hours. This affects the times displayed in the Results
and Track Points Panes, as well as the time scale in the Speed Graph. |
| Zoom - this affected the speed of the zoom on the mouse
track-wheel. Each click ofthe mouse track wheel will zoom in or out by this
amount. It also affect the zoom when the Zoom Out or Zoom In is selected on
the context menu for the Map View or Speed Graph. |
| Capture focus on mouse move - Standard Windows behavior is to lock
mouse movements to the window that has the focus. However RealSpeed has 4
interactive screens that the user switched between rapidly including the Map
View, the Speed Graph, the Results and the Track Points Panes. It is very
inconvenient to have to click into each window manually before applying
mouse actions to each screen. So selecting this option means that RealSpeed
will monitor the mouse movements and apply the actions to the screen that
lies under the mouse. This is done by automatically changing focus to the
window that lies under the mouse whenever the mouse is moved. |
| Time Threshold - If a gap in time is found between track points
that is greater than the value set here, it is assumed that this gap is a
break in the trackpoints. Any distances between the points is not included
in the total distance and any speed achieved is ignored. The default value
is 200 seconds which means that any break between track points greater than
200 seconds is not a part of any results. |
| Speed Threshold - Any speed value that exceeds this value will be
flagged as invalid. See below for more information of what an Invalid track
point is. |
| Acc and Decc Threshold - This is an acceleration threshold that helps to
determine a spike in the track data. This is not a particular issue for the
Locosys GT11 GPS using doppler data because the data is so accurate and has
data quality information to identify bad data, but for older units like the
Garmin it is very important. The value specified is actually a maximum
allowed variance from the average value of its neighboring points, in
Display Units per second. This means that if set to 5 and the display units
is knots, then if a track point is found with a speed over 5 knots/second
greater than the average of its neighboring points, then it is flagged as
Invalid. The Decc threshold is the same as the acceleration threshold but
limits the amount of deceleration accepted. Generally a higher deceleration
than acceleration is acceptable. |
| Max HDOP - HDOP is Horizontal Dilution of Precision, a measure of
the ability to triangulate a location from the satellite data. If the
satellites are well spread around the sky and there are lots of satellites,
then this value will be small (good) around 1. If there are not many
satellites or they are all in the same area of the sky then the calculation
of the latitude and longitude will contain higher error sothe HDOp value
will be high (over 4 and up to 50 for a total loss of accuracy). RealSpeed
uses this specified value as a threshold so that any track point with a a
HDOP greater than this specified value will be flagged as invalid. |
| Min Sats - this is teh minimum number of satellites that make a
good track. If the satellite count gets below this threshold then the track
point will be marked as Invalid |
| Stop Run Speed and Stop Run Angle - these options control how
RealSpeed determines a run. This is used with the One Result per Run setting
in the Divisions Options. To determine the end of a run, set the threshold
stop run speed that you consider to be the end of a run. Likewise, you can
set the maximum deviation of direction to determine the end of a run, such
as 90 degrees that would indicate a reversing of direction. |
| Doppler and Track Point Error - These settings control how
RealSpeed determines the error in the track point data for calculating
Claimed Speed. Enter the error values as specified by the GPS maker. |
