About Orolia's GNSS Simulators
The GSG-5™ and GSG-6™ Series of GNSS Constellation Simulators provide a wide-range
of capabilities for in-line production testing and development testing, including navigational
fix and position testing, while offering ease-of-operation.
GSG-51 is a single-channel GPS L1 RF generator, capable of emulating a single GNSS sig-
nal. One of the main applications for these cost-effective units is fast manufacturing testing
of GPS receivers.
GSG-5 Series simulators reproduce the environment of a GNSS receiver. Depending on
the configuration, these units simulate up to sixteen GNSS satellites, up to 3 SBAS satel-
lites, together with optional multipath and interference signals. The GSG-5 Series applies
models to simulate satellite motions, atmospheric effects, and different antenna types. The
movement of the GNSS receiver under test is defined using NMEA data or pre-defined tra-
jectory models.
GSG-6 Series simulators add advanced features and the capability to simulate up to 64
satellites (configuration-dependent) on different frequency bands simultaneously. New sig-
nal types include GPS L2P, L2C and L5, GLONASS L2, Galileo E1 and E5a/b, BeiDou B1
and B2, and QZSS L1 C/A, L2C, L5 and L1 SAIF, IRNSS L5.
1.3 Key Features
Since GNSS testing requirements may vary considerably from application to application,
GSG Series simulators are available in a multitude of configurations (see
"GSG Series
Model Variants and Options" on page 203 ).
Some of the key features are:
