System and method for meteorological modelling

A system for meteorological modelling, the system comprising global navigation satellite system comprising:

• a space segment having navigation satellites,
• a control segment having ground-based satellite stations, and
• a client segment having a plurality of navigation satellite signal receiving client nodes, wherein the client segment comprises an infrastructure network comprising a plurality of separate infrastructure network nodes provided over a geographical area, the infrastructure network nodes comprising:
• an infrastructure network communication module configured to carry out data exchange in the infrastructure network,
• a navigation satellite system module having a navigation satellite system receiver configured to receive navigation satellite system signals from the navigation satellites of the global navigation satellite system, and
• an infrastructure network control module configured to control data exchange via the infrastructure network communication module and to control operation of the infrastructure network node based on the received navigation satellite system signals, the system further comprising a meteorological modelling module configured to:
• determine the atmospheric delay of the navigation satellite signal between the navigation satellite and the infrastructure network node, and
• calculate an atmospheric quantity between the navigation satellite and the infrastructure network node based on the determined atmospheric delay of the navigation satellite signal between the navigation satellite and the infrastructure network node.

A method for meteorological modelling, wherein the method being carried out in connection with an infrastructure network comprising plurality of separate infrastructure network nodes provided over a geographical area, the method comprising:

• carrying out data exchange in the infrastructure network,
• receiving navigation satellite system signals from the navigation satellites of the global navigation satellite system in the infrastructure network nodes, and
• controlling operation of the infrastructure network nodes based on the received navigation satellite system signals,
• the method further comprises:
• determine atmospheric delays of the navigation satellite system signals between the navigation satellites and the infrastructure network nodes based on the received navigation satellite system signals, and
• calculating atmospheric quantities between the navigation satellites and the infrastructure network nodes based on the determined atmospheric delays of the navigation satellite system signals between the navigation satellites and the infrastructure network nodes.
