equipped with a radiating collector. This is probably not acceptable for an inexpensive demonstration program. 6.3 Space Shuttle Options In option 1 (deployment of a subsatellite from a GAS Can), the proposed arrangements for Ariane 4 apply, provided the subsatellite antenna has a 2- meter min. diameter, taking account of the .45 meter diameter antenna. Option 2, (deployment of transmitter & receiver from a GAS), would also require the same transmitter arrangement, with the possibility of extended transmission ranges if antenna/rectenna of larger sizes are permitted. Option 3 (use of hitchhiker G&M). HH-G or -M provide less constraints than the above carriers. • available power 1,3 kW • easier thermal dissipation • greater aperture for both transmitter and receiver. This would enable using Ku-Band TWTs in the range of several hundred Watts, such as:
