Note: This feature only works if the file type of both the Input, and Output tra
jectory is NMEA , and if the Output destination is set to Write to file .
4.9.11 Creating an RSG Trajectory with StudioView
What is an RSG trajectory?
RSG trajectories

are used primarily to simulate airborne applications, such as flight, missile or
orbital trajectories. Contrary to a
standard
trajectories (as described under "Creating a Tra
jectory in StudioView" on page 123), an RSG trajectory is not defined by its geographic pos
ition, but by
relative changes of movement .
These motion changes are captured in user-defined parameters which are assigned to SCPI
commands (to learn more about SCPI commands, see "SCPI Guide: Introduction" on
page 214). RSG trajectories are created and edited with StudioView's RSG Trajectory Editor.

Note that RSG trajectories must be built
prior to running them. However, there is also the concept of
feeding trajectory data into the GSG unit in real-time, i.e. while the trajectory is being generated: This
functionality requires the option kit
OPT-RSG
, which allows the GSG unit to receive trajectory inform
ation in real-time from e.g., a motion simulator or a computer running simulation software. For more
information, see https://spectracom.com/products-services/gnss-simulation/real-time-trajectories.
4.9.11.1 Using the RSG Trajectory Editor for the First Time
To open the StudioView RSG Trajectory Editor:
In StudioView, click in the main toolbar, the Tools menu, or in the StudioView Applic
ation Tips startup screen. The editor screen will show (the image below shows a loaded
scenario for illustration purposes.)
The editor has three panels:
1.
The left panel shows a list of all RSG commands for the trajectory currently open
(if any).
2.
The corresponding trajectory is visualized on the Google Map on the right.
3.
The charts below the m ap show speeds and altitude over time.
