SimAUTO In-Vehicle Navigation System (IVNS) Software

SimAUTO enables testing of integrated navigation systems comprising GPS and Dead Reckoning (DR) sensors. SimAUTO is used in combination with a Spirent GPS/GNSS simulation system. Coherent GPS and DR sensor emulation facilitates rapid and comprehensive system testing, accelerating time to market while improving demonstrated system resilience to real-life challenges such as multipath interference and signal obscuration.

Fully integrated with Spirent's SimGEN for Windows® 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 coordinated with the GPS RF signals to provide a complete test environment for integrated navigation systems.

A conversion utility allows NMEA data logged during field trials to be captured as a motion file so an identical journey can be reproduced as many times as required without leaving the lab.

Key Features

• Simultaneous emulation of multiple DR sensors consistent with GPS satellite RF
• Heading and wheel count sensor outputs
• Single-axis rate table drive for stimulation of heading sensors
• User-defined vehicle geometry
• Real-time scenario editing
• Remote operation driven from file (logged data) or vehicle simulator
• Data streaming output allows modeled vehicle motion to be shared with other applications
• CAN messages consistent with modeled sensors available to your CAN specification
