340A: Indoor Positioning
with GNSS and Other Sensors I
Back to main tutorials page |
| |
Attendees will
receive an overview of GNSS receiver implementations as they apply
to navigation indoors or in degraded environments. Receiver
architectures, including high- sensitivity techniques
and assisted-GNSS concepts, are analyzed with respect to indoor
system errors and other factors. |

| Augmenting
technologies are discussed with emphasis on the integration with
inertial sensors. Advanced receiver architectures are presented and
compared as techniques for improving performance indoors. Several
case studies are presented to illustrate and support the key topics
addressed. |
