Abstract
Disclosed are systems, apparatuses, processes, and computer-readable media for wireless positioning. For example, a computing device can determine, based on an elevation of one or more satellite vehicles (SVs) of a plurality of being is greater than an elevation threshold, one or more positions of a device based on measurements (from a minimum number of SVs of the plurality of SVs with the elevation greater than the elevation threshold) that have measurement errors less than or equal to a current horizontal error position estimate (HEPE) for the device.
Claims20
An apparatus for device positioning, the apparatus comprising:
- at least one memory;
- and
- at least one processor coupled to the at least one memory and configured to:
- determine a positioning condition associated with a change in trajectory of a device and one or more signal obstructions affecting signals from a plurality of satellite vehicles (SVs) with respect to the device;
- select, based on the determination of the positioning condition, a subset of SVs of the plurality of SVs based on at least one of respective elevations of the subset of SVs or respective measurement errors associated with respective signals from the subset of SVs;
- and
- determine one or more positions of the device based on measurements from the subset of SVs.
A method for device positioning, the method comprising:
- determining a positioning condition associated with a change in trajectory of a device and one or more signal obstructions affecting signals from a plurality of satellite vehicles (SVs) with respect to the device;
- selecting, based on determining the positioning condition, a subset of SVs of the plurality of SVs based on at least one of respective elevations of the subset of SVs or respective measurement errors associated with respective signals from the subset of SVs;
- and
- determining one or more positions of the device based on measurements from the subset of SVs.
