Parameter Description
<waypointfor- Defines the format of the waypoint data.
mat> The possible values are:
●
"positiononly"
Only waypoint data
●
"position_attitude"
Waypoint and attitude data
●
"position_velocitymagnitude"
Waypoints and velocity magnitude information per point
●
"position_velocitymagnitude_attitude"
Waypoints, velocity magnitude and attitude data
●
"position_velocityvector"
Waypoints and velocity vector per location
●
"position_velocityvector_attitude"
Waypoints, velocity vector and attitude per point
The three <property waypointformat="*_attitude"> formats
require option R&S SMW-K108. If you load files containing these formats
in instrument without this option, the file is discarded and an error mes-
sage displayed.
Smoothening is only possible with <property
waypointformat="positiononly"> and NMEA, waypoints and
*.kml.
The description of the waypoints has to follow the selected format.
For example, <waypointvector
data="0.05,144.966662392613,-37.8166632247233,
100.000000039116"/> with <property
waypointformat="positiononly"/> and
<datavectorhastimestamp="yes">.
<datavectorhas- Determines the way the time stamp (elapsed time starting simulation
timestamp> time) is defined.
●
With <datavectorhastimestamp="yes">
The time stamp of a waypoint is retrieved from the
<waypointvector data>, as the first data vector parameter.
●
With <datavectorhastimestamp="no">
the time stamp is internally calculated based on the following rule:
–
<coordsystem> Defines the coordinate system used by the definition of the
<waypointvector data>.
Possible values: "enu", "cart ecef", "geod wgs84" or "geod pz90"
<timeresolution> If <datavectorhastimestamp="no">, applies implicitly time stamps
to waypoints. Otherwise, the time stamp is retrieved automatically, see
<datavectorhastimestamp>.
<enurefpoint> Coordinates of the reference waypoint in ENU format
<endbehaviour> Determines the behavior of the moving object at the end of the trajectory.
Possible values: "jump", "return", "stop"
<attitudeunit> Defines the unit ("rad" or "deg") the attitude is expressed in
The time stamp of first waypoint is T
The time stamp of the waypoint
