1 : The Ultimate Solution for 3-D Indoor Position GNSS GNSS GNSS Dinesh Manandhar GNSS Technologies Inc., Japan 3rd Invitational Workshop on Opportunistic RF Localization for Next Generation Wireless Devices Co-located with Geo-location and emergence of indoor applications May 7, 2012, New Orleans, LA, USA

2 Characteristics of Same Signal Structure as GPS/GNSS Replace NAV Data by Position Information: LLH and Floor ID Compatibility with GPS Receiver Seamless Navigation No Need to Compute Pseudorange No Additional Power Consumption at the Receiver No Change in Receiver Hardware One Tx. Unit provides 3-D Position Data Provide Stable Accuracy No Clock Synchronization at the Transmitter 2
