Real-time Scenario Generation
Easy Integration for Hardware-in-the-Loop (HIL) Testing

• Real-time input option for GSG Series
GNSS simulators
• Integrated INS+GNSS Receiver testing
• Control Trajectories using 6DOF
• Low xed latency from command input
to RF output; low jitter
• Allows for unlimited trajectory length
• Option includes GSG StudioView™
Software

The Real-time Scenario Generation (RSG™) option for the GSG
products supports xed latency streaming of 6DOF trajectory
information via position, velocity, acceleration, or heading
commands. Vehicle attitude and attitude changes, as well as satellite
power levels, are also controllable via real-time commands. The RSG
option allows the input of real time trajectory data from external
devices or software via commands which support setting position,
velocity, acceleration, orientation, or heading independently. This
allows for external control of all or some of these parameters
depending on your simulation needs or capabilities. See Figures
1, 2, and 3.

convenient of either standard interfaces provided on the GSG
Series Simulators, USB or Ethernet. For the best performance, USB
is preferred.

Interface

The RSG option expands on the powerful trajectory options for the
GSG Series Simulators. This option allows trajectories of unlimited
duration to be streamed into the simulator making the le size
limitation for trajectories inapplicable. Trajectories are now also
specied in this new format that makes creation of high dynamic
trajectories simple and convenient.

The RSG option takes advantage of the NI VISA driver and SCPI
protocol to allow data to be streamed in from numerous sources
including external software programs and GSG StudioView™
software. This approach allows the exibility to choose the most

Hardware-in-the-loop Integration
The GSG Simulator with the RSG option is easily integrated into a
Hardware-in-the-Loop (HIL) test system. The simulator will provide
feedback for underow and overow conditions to easily allow
error detection. The xed latency allows for easy system wide
compensation.
