1. A method for creating a correction function for improving the accuracy of a GPS device, the method comprising:
collecting multiple time samples at multiple known locations wherein each time sample consists of GPS coordinates and associated satellite data from multiple satellites, wherein the satellite data includes or permits determination of (i) satellite azimuth and elevation of an associated satellite, and (ii) Signal-to-Noise Ratio of a received signal from the associated satellite;
for each time sample computing a respective error between the known location and the corresponding GPS coordinates; and
creating an error correction function as a function of the respective GPS coordinates and the satellite data by applying deep learning/machine learning techniques to the multiple time samples.
