Title:
Ground positioning system calibration
Document Type and Number:
Japanese Patent JP6042568
Kind Code:
B2
Abstract:
Embodiments disclosed aggregate a plurality of crowdsourced measurement sets for antennas received from a plurality of Mobile Stations (MS) with a Base Station Almanac (BSA), based on a measurement location estimate and a measurement location uncertainty estimate associated with each measurement set. A map comprising a plurality of map layers may be obtained, where each map layer associates locations in the BSA with spatially variable Forward Link Calibration (FLC) values for the antenna derived from the updated BSA data, wherein each spatially variable FLC value is associated with a corresponding location in the updated BSA data. Map layers, which may also include multipath map and/or received signal strength layers, may be provided to MS′ as location assistance data.
