To continue working in the future and to maintain the services we depend on, geodesy needs more frequency bands.
When sharing the radio spectrum for major international conferences, geodesians must absolutely be present at the negotiation table.
Among the solutions envisaged, one can also imagine zones of radio silence around essential radiotelescopes. A job is also underway with satellite operators to prevent their radio emissions from being directed directly to these telescopes.
At any rate, Any solution should be global. For geodetic measures, radiotelescopes are interconnected on the planet’s scale, which makes it possible to simulate a large telescope like the earth. However, today, the allocation of radio spectrum frequencies is mainly managed by each state independently, which complicates any coordination.
The first step may be to make this problem better known. If we want GPS to work, supermarkets are supplied and our bank transfers arrive safely, we must keep a clear view of the black holes of distant galaxies – which means unclogging the radio spectrum.
