SimTESTTM: Test control with
route-matched trajectory data from Google Maps®
Single Channel Utility: Simulate one
channel per constellation with specified signal parameters. Switch signals and
codes on/off via remote command
The
GSS7000 offers exceptional accuracy, fidelity and authentic GNSS signal
emulation across the entire series ensuring true performance at every test
stage. A full range of hardware integration signals are provided including 1PPS
in / out, 10MHz in / out and hardware trigger.
The
GSS7000 Multi-GNSS Simulator is supported by a range of scenario generation and
simulator control software packages including Spirent’s feature-rich SimGEN.
Each software package has a range of capabilities from the all-inclusive SimGEN
to packages more suited to production or integration / verification test
processes.
SimGEN
offers a complete and flexible scenario generation capability including control
of the constellations, propagation, terrain obscuration, antenna patterns,
multipath, vehicle trajectory and a range of error models.
SimREPLAYplus
enables the user to define vehicle motion remotely as well as adding the
ability to edit the time, date and position. SimREPLAYplus allows users
to generate scenarios locally.
SimTEST
offers easy to use yet precise capabilities for general testing, including
generation of route-matched trajectory data from Google Maps
Single
Channel Utility offers the capability to simulate one
channel per constellation via remote commands. Perfect for many production test
scenarios.
