Regional position estimator for network devices

A device comprising:

• a processor;
• a memory communicatively coupled to the processor;
• at least one global navigation satellite system (GNSS) receiver configured to receive a plurality of signals from one or more satellites;
• and
• a location identification logic, configured to:
• identify a first contour of geolocations;
• retrieve an estimated location of the device;
• determine an area of overlap between the first contour and the estimated location, wherein the area of overlap forms an ellipse;
• and
• determine a location of the device based on the area of overlap in real-time.

A method comprising:

• determining a first pseudo range difference based on a first signal and a second signal received by a device from a first satellite in a first time period;
• identifying a first contour of geolocations having the first pseudo range difference corresponding to the first satellite in the first time period;
• retrieving an estimated location of the device;
• determining an area of overlap between the first contour and the estimated location, wherein the area of overlap forms an ellipse;
• and
• determining a location of the device based on the area of overlap in real-time, wherein the device is stationary during the first time period.
