SimAUTO is a powerful upgrade for Spirent's multi-channel simulators to provide lab test support for today's multi-sensor
In-Vehicle Navigation Systems (IVNS).
SimAUTO provides a turnkey solution to testing integrated
navigation systems comprising GNSS and dead reckoning (DR)
sensors. Coherent GNSS and DR sensor emulation facilitates rapid
and comprehensive system testing, accelerating time to market
whilst improving demonstrated system resilience to real-life
challenges such as multipath interference and signal obscuration.
Fully integrated with Spirent's SimGENTM software suite, SimAUTO
allows parameters such as wheel track, wheel base, wheel
diameter, odometer pulse rate & dead band to be set and saved to
a vehicle personality file for future use.
Emulated dead-reckoning sensor outputs are precisely
co-ordinated with the RF GNSS signals to provide a complete test
environment for integrated navigation systems. Additionally,
single-axis turntable drive is provided to allow the direct
stimulation of heading or heading rate sensors if this is
appropriate or preferred.
The emulated sensor outputs and rate table drive are generated by
cards installed into the controller PC running SimGENTM. Specify a
rackmount PC to ensure sufficient PCI slots.
Vehicle trajectory can be generated using SimGENTM, delivered
from an external source or from a file using pirent's SimREMOTE
mode of operation.
A conversion utility allows NMEA data logged during field trials to
be captured as a motion file. An identical journey can thus be
reproduced as many times as required without leaving the lab.
