(Upfront and/or operating) costs? Size (70m) and pointing problems? As for international problems: Australia and Spain are quite stable, aren't they?

As for international problems: Australia and Spain are quite stable, aren't they? Analyst Yes they are, but if an international problem occurs, as far as we know it will be unpredictable, unforeseen. So, when thinking of redundancy and reliability, we cannot say a priori that some countries are stable and others not. It is only a matter of probability. There is little political interest to duplicate an antenna in Spain, but anyway if the network is saturated, this antenna will have to be duplicated and it will be safer to do this in another country. Think that Europe is in the process of duplicating the GPS system (with Galileo) at high cost, for the only reason that it is controlled by the USA, however a long friend, ally and helper country. This is not a criticism of the USA, but a wise caution. |
