Powerful

simulators

Simulation is simply the best way to test and verify proper operation of devices,
systems and software reliant on global navigation satellite signals. Orolia GSG-5/6 series
simulators are easy to use, feature-rich and aordable to oer the best value compared
to alternative testing tools or the limitations of testing from “live sky” signals.

Basic Principle

GSG-5/6 simulators can generate any combination of GPS, GLONASS, Galileo,
BeiDou, QZSS, SBAS satellite signals under any condition simultaneously through
a single RF output (type N connector). Congurations with higher channel counts
generate new, modernized, signals on any of the navigation frequencies, including
IRNSS, even those currently under development. Based on a test scenario that
includes date, time and power levels, the generated signals correspond to any
position on, or above, the earth (below the satellite orbits at approximately 20,000
km). It is easy to test dynamic conditions by dening a trajectory of the receiver
under test. The simulator manages all the dynamics including relativistic eects.

GSG-5/6 Series: Advanced GNSS Simulators

Simple Set-up and Operation

Even the most inexperienced operator can
congure scenarios on the y without the need
for an external PC and pre-compilation phase.
Via the front panel, the user can swiftly modify
parameters. Each unit comes with a license
for GSG StudioView™ Windows software to
graphically create, modify, and upload scenarios.
A Google Maps interface makes trajectory
creation easy. Trajectories can also be dened
by recorded or generated NMEA formats.

Connectivity Extends Ease-of­use and Flexibility

GSG simulators can be controlled via an Ethernet
network connection, USB or GPIB. A built-in
web interface allows complete operation of
the instrument through front panel controls. It
also allows for le transfers. Connectivity also
supports the integration of GNSS simulation
into a wide range of other applications. There
is an option to control signal generation in real­time through a simple command set. It can
synchronize to external systems in many other
ways based on its precision timing capabilities
and the ability to automatically download
ephemeris and almanac data via RINEX les.
