-----BEGIN PGP SIGNED MESSAGE----- other electronic communications that its computers have been pre-programmed to select for all the allies and automatically send this intelligence to them. This means that New Zealand stations are being used by the overseas agencies for their automatic collecting - while New Zealand does not even know what is being intercepted from the New Zealand sites for the allies. In return, New Zealand gets tightly controlled access to a few parts of the system. The GCSB computers, the stations, the headquarter operations and, indeed, GCSB itself function almost entirely as components of this integrated system. Each station in the network - not just the satellite stations - has Dictionary computers that report to the ECHELON system P37 United States spy satellites, designed to intercept communications from orbit above the earth, are also likely to be connected into the ECHELON system. These satellites either move in orbits that criss-cross the earth or, like the Intelsats, sit above the Equator in geostationary orbit. They have antennae that can scoop up very large quantities of radio communications from the areas below. A final element of the ECHELON system are facilities that tap directly into land-based telecommunications systems, completing a near total coverage of the world's communications. The microwave networks are made up of chains of microwave towers relaying messages from hilltop to hilltop (always within line of sight) across the countryside. These networks shunt large quantities of communications across a country. Intercepting them gives access to international underseas communications (once they surface) and to international communication trunk lines across continents. They are also an obvious target for large-scale interception of domestic communications. Of course, when the microwave route is across on -----BEGIN PGP SIGNATURE----- Version: PGPfreeware 6.7.4 lvVUpCPWOjbpNWLc1EslmxU3HtLiCL9zd2l9k6gv00WlJB55lBhoWCWhrPIgXPJU hnN5bF2L2hljKPpt1f63UVv9t8GQYu9gU4Yx/d0MycgziiLZvqXU/vpnVXrBYcnG yE9QUL28ixlYWjfaff7WimTIoyiF0y/OzZBda+BMLHdSd3HYKqw8FTQuS/0wa/+L fbM5L2Xlu8afa9p9uN== =UvQI -----END PGP SIGNATURE-----
