ABSTRACT:
A method and system for taking direct measurements of GNSS signal's arrival angle to remotely measure the atmospheric variables used for weather prediction. More specifically, an improved method and system for obtaining and processing accurate information regarding the weather and other atmospheric changes by measuring the total refractive bending angle of the GNSS signal. For mobile platforms on which receivers are mounted, phased array receivers are used to allow precise measurements of GNSS arrival angles. By measuring the refractive bending angle, more accurate and cost-efficient measurements of atmospheric changes are obtained, thereby resulting in more accurate predictions of the weather.
