4.9.8 Creating a Trajectory in StudioView
What is a Trajectory?
In the context of GNSS testing, a trajectory is the predefined path a receiver is traveling
during the execution of a scenario. It is the input to the scenario that defines how the vir-
tual vehicle will move in up to 6 degrees of freedom during the test (X, Y, Z; pitch, roll,
yaw).
While the definition of the vehicle path itself is an important constituent of any scenario,
the GNSS signal reception at any given time during scenario execution is of equal import-
ance, since the reception will be affected by these trajectory-dependent factors:
The environment along the trajectory changes: Infrastructure blockages such as tall
buildings ("urban canyons") or other topographic characteristics will cause the signal
reception to vary.

A resource string (e.g., "TCPIP::10.32.1.203::inst0::INSTR") can point to a USB or GPIB connection. It is generated auto-
matically when you add a new connection and its IP address becomes validated.
