The Author tries to “think out of the box”, presenting “Sponsalia ex hoc mundo” (“Hand fastening out of this world”). The title reflects the view that the outer space sciences and the sea sciences are analytically separable, but practically interlinked. It might be observed in the context of space technology and satellite technics, a new system of management and government, as well as a new system of law and policy. Nowadays, the outer space infrastructure (the use of artificial Earth satellites for Direct Television Broadcasting, communications, remote sensing, navigation, military missiles) affects infrastructure of our Planet, including maritime infrastructure. There is, therefore, the need for a new face of integrated system of science and practice.
The paper presents national report of Poland for IAG on positioning and applications. The selected research presented was carried out at leading Polish research institutions and concern precise multi-GNSS satellite positioning – relative and absolute – and also GNSS-based ionosphere and troposphere modelling and studies. The research resulted in noticeable advancements in these subjects confirmed by the development of new algorithms and methods. New and improved methods of precise GNSS positioning were developed, and also GNSS metrology was studied. New advanced troposphere models were presented and tested. In particular, these models allowed testing IPW variability on regional and global scales. Also, new regional ionosphere monitoring web-based services were developed and launched.
