Description
<general>
<property>
<waypointfor-
mat>
Defines the format of the waypoint data.
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-
timestamp>
Determines the way the time stamp (elapsed time starting simulation
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:
–
The time stamp of first waypoint is T
1
= 0
The time stamp of the waypoint
N
is T
N
= (N–
1)*
<timeresolution>
<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
