GNSS-METEOROLOGY: OPPORTUNITIES AND PROSPECTS FOR DEVELOPMENT IN RUSSIA AND ABROAD

The article considers the possibilities and prospects for the development of GNSS meteorology based on domestic and foreign research. It is noted that the tropospheric delay of the GNSS signal is a valuable source of information about the state of the troposphere. The algorithm for estimating tropospheric delay and the services that perform this assessment (international GNSS service IGS and online service GAPS) are described. The content of the IGS output file with tropospheric delays at the IGS point is considered. The necessary conditions for the implementation of GNSS meteorology are listed, as well as structural diagrams of existing GNSS meteorology systems in the United States and Japan. It is shown that research in this area is being carried out in Russia. It is concluded that the network of permanent base stations in the Novosibirsk Region has the potential for the development of GNSS meteorology in the covered area.
