US 2025/0060491 A1 · GPS SLOPE DETERMINATION

Abstract

Disclosed are a device, computer program and method, for determining a range to a target, the device comprising a global positioning system (GPS) receiver, a pressure sensor, a temperature sensor, a controller; wherein the method comprises determining the device's geographic location based on coordinates from the GPS receiver and the device's elevation based on pressure and temperature data from the sensors; obtaining a location and elevation of a landmark based on GPS coordinates from a database; determining a distance between the device and the landmark using GPS coordinates; applying a slope compensation based on the difference in elevation between the device's elevation and the landmark; and converting the distance to a signal perceptible to a user.

Dependent claims

A device for determining elevations, the device comprising:

a controller and a non-transitory computer readable storage medium comprising a plurality of computer readable instructions embodied thereon which, when executed by the controller, causes the controller to:
determine a first geographic location of the device;
obtain a reference elevation of the first geographic location;
determine the device's pressure elevation based on pressure and temperature values at the first geographic location;
compare the device's pressure elevation to the reference elevation;
and
determine an elevation offset factor based on the difference between the device's pressure elevation and the reference elevation.
