GPS Testing for Automotive/Telematics Navigation Applications
The automotive environment represents an extreme challenge for satellite navigation systems. High user demands conflict with complex signal environments and the need for low cost systems. GPS positioning is typically supplemented by additional inertial or dead reckoning sensors to improve performance.
Spirent Solves Your IVNS Test Challenges.
Spirent offers test systems for Integrated Vehicle Navigation System (IVNS) testing that include simulated GPS signals coherent with inertial and Dead Reckoning (DR) sensors. Our systems can be controlled remotely, facilitating integration with other vehicle test rigs. Real-time hardware-in-the-loop simulation is also possible, for example to allow synchronization with driving simulators. Systems are also available that are optimized for vendor selection, integration and verification testing.
