Title:
Low-Earth Orbit (LEO) Satellite Position, Velocity, and Time (PVT) Determination for LEO-based Positioning
Document Type and Number:
WIPO Patent Application WO/2023/283867
Kind Code:
A1
Abstract:
Position, Velocity, and Time (PVT) information of a LEO satellite (320) can be determined by leveraging a known position of a mobile device (310) comprising a terrestrial satellite receiver of the LEO satellite (320) and using range information (range and/or range rate) (330) of the LEO satellite (320) taken at the mobile device (310). This PVT information can be shared by the mobile device (310) with the server (430) and/or other mobile devices (310-1, 310-2,……310-m), and information from multiple mobile devices (310-1, 310-2,……310-m) can be crowdsourced to determine robust PVT information for a LEO satellite (320). Once the PVT information is determined, it can be used to subsequently for positioning of the mobile device (310) and/or other mobile devices (310-1, 310-2,……310-m).
