2、TU Radio Regulations, proposed geostationary-satellite networks in the FSS may require b) that there is a need to determine whether a given FSS network might be affected by another FSS network; c) that it is desirable to eliminate from coordination those networks which are not likely to be affected;
3、 d) techniques to reduce the number of satellite networks involved in the coordination process; that as further information on proposed networks becomes available, it is possible to use one or more e) taking into account the actual signals being used, the system configurations, orbital spacing, etc.
4、 that detailed coordination entails calculation of the relative levels of the wanted and interfering carriers, f) indicating the relationship among these calculation methods, that several calculation techniques may be used in coordination.
