Abstract
A constellation of individual satellites are employed to concurrently collect occultation data from multiple GPSS originating signals that pass through atmospheric sections of interest. By coordinating the collection and processing of the data using state of the art receivers on a constellation of low earth orbit satellites and networked processing, highly accurate calculation of atmospheric conditions and related future weather events are possible.
Claims16
A system for determining atmospheric conditions, comprising:
- a transmission link to a plurality of satellite-based radio transmitters from one or more Global Navigation Satellite Systems (GNSS), wherein the transmitters transmit radio signals and said signals comprise data reflecting occultation of GNSS based radio signals collected from multiple paths by a constellation of satellites placed in low earth orbit;
- a computer linked database storing said data;
- and
- a computer processor implementing an occultation analysis algorithm to ascertain atmospheric conditions for use in identifying weather conditions associated with said occultation data.
A method for assessing atmospheric conditions comprising:
- collecting radio occultation (RO) data from a plurality of satellites based on a Global Navigation Satellite System (GNSS) signal tracking;
- collecting image data regarding a region of atmosphere of interest;
- storing in computer memory RO and image data;
- and
- processing RO and image data to ascertain properties about select regions of atmosphere.
A database and associated processor platform in communication with a plurality of low earth orbit satellites, said platform comprises:
- a. A communication link to said satellites assessing and recalling satellite data on atmospheric occultated signals;
- b. A database storing said data with time, Global Navigation Satellite System (GNSS) and location information regarding each occultated signal;
- c. A computer processor programmed with one or more occultation analysis algorithms in communication with said database for implementing said algorithm and rendering projections based on atmospheric conditions determined by said algorithm;
- and
- d. System output link to deliver projections to one or more network affiliates platform.
