Abstract: This disclosure describes methods, systems and machine readable media that can provide position solutions using, for example, pattern matching with GNSS signals in urban canyons. In one method, based upon an approximate location in an urban canyon and a set of 3D data about building structures in the urban canyon, an expected signal reception data can be generated for both line of sight and non-line of sight GNSS signals from GNSS satellites, or other sources of GNSS signals, at each point in a set of points in a grid (or other model) in the vicinity of the approximate location). This expected signal reception data can be matched to a received set of GNSS signals that have been received by a GNSS receiver, and the result of the matching can produce an adjustment to the approximate location that is used in the position solution of the GNSS receiver.

Abstract: A water bottle for pets comprises a stainless steel canister, a liquid dispenser, a removable screw cap. The canister is used for containing water and has a closed end and an open end. Threads are positioned near the open end of the canister. The removable dispenser has threads for engaging the threads near the open end of the canister and a pet-operable drink valve. The removable screw cap selectively covers and uncovers the pet-operable drink valve.
