Comprehensive test control
With SimGEN you can test GNSS performance in everyday, extreme and adverse environments, with full control of test parameters (including time, date and power levels).
SimGEN supports a comprehensive range of current and future GNSS signals, including GPS, GLONASS, Galileo, BeiDou-2, WAAS, EGNOS, MSAS, GAGAN, SDCM, QZSS and IRNSS, dependent on simulator and user authorization.
Reduced test costs and times
By creating accurate, comparative testing with perfectly repeatable test scenarios, users can save time and money by moving tests out of the field and into the lab.
Easy to use
Its extensive default settings ensure even a fairly complex scenario can be selected, run and be simulating a GNSS receiver with RF signals in less than a minute. Its intuitive interface and time-saving features have been honed over Spirent’s long history at the leading edge of satellite navigation and positioning testing.
More accurate testing
SimGEN offers comprehensive modelling of errors and environmental effects, including multiple mechanisms for applying declared and undeclared errors and modifications to nav data, satellite clocks, orbits. Users can also create and use antenna reception gain and phase patterns, several models for multipath reflections, terrain obscuration, atmospheric effects including ionospheric scintillation, and much more.
Software adapted to user needs
SimGEN is part of a family of software and users can select features based on needs, such as in-vehicle navigation, sensor fusion, inertial systems, classified and other signals.
Spirent GNSS simulator systems support public-domain signals but some can be upgraded for authorised users only to generate authorised signals using combinations of hardware upgrades and additions to SimGEN. Spirent regularly updates SimGEN software. As such, graphical
representations of the software appearing here should be considered as typical and for
illustrative purposes and are subject to change and enhancement.
