this dropdown list, you have to create a new trajectory first and then save it in the
repository.
An Events file describes some specified events during scenario execution. To create
events file, see "Defining Events in StudioView" on page 155 .
Support for environmental or vehicle models in GSG simulators is via compressed
keyhole markup language files (kmz) popularized by Google Earth. A simple way to
create these files is with the tool SketchUp available from Trimble

An Environment model is a 3D model of the environment, describing terrain, build-
ings, etc. All environment models used must have a ‘geo-location’ added to them
before they can be used by in simulation. Environmental Modeling is used first and
foremost to simulate urban canyons, or tunnels. You can create blocks, representing
buildings/obstructions, and place them on the map along the trajectory. The power
level of the satellites will be blocked or reduced in the vicinity of the buildings due to
the obstruction of the line of sight near these virtual buildings.
A vehicle model represents a 3D model of the vehicle. The vehicle model will move
with the simulated trajectory. The vehicle model will also follow any pitch/roll/yaw
movements simulated, i.e. if the vehicle rolls by 90 degrees, half of the sky is likely to
be blocked by the vehicle itself, depending on vehicle model used. The body center
of the simulated vehicle will be in the origin position of the model. The antenna pos-
ition can differ from the body center position by configuring lever arm values in the
scenario configuration. The antenna position can also be specified in the vehicle
model file by adding a component named “RecAnt”. If both lever arm and RecAnt
are set, the receiver antenna position as set in the vehicle model takes the pre-
cedence. The vehicle model does not need a geo-location.
Vehicle models can also be created with the software tool “Sketchup”, see above.
