<p>A series of spacecraft designs (10, 32 and 118) for a Satellite Communication System is disclosed. One of the preferred embodiments of the invention called 'Domesat' (10) includes a hemispherical, high-gain, electronically-steered antenna array (12) that is always pointed toward the Earth (E). Hexagonal antenna panels (14) are held together by tubular and spherical connectors (28 and 30). The upper portion of the satellite (10) incorporates a space-facing array (18) of panels (20) which are always pointed toward the zenith (Z). The interior of the dome-shaped antenna array (12) is used to store solar cell panels (16) which unfurl through an opening (15) in the space-facing array (18) when the spacecraft (10) reaches its final orbit. Another embodiment of the invention called 'Batsat' (118) comprises a central body (120) and two arms (122 and 124) that include disc-shaped antenna panels (131-139) and solar/thermal panels (140 and 141).</p> |
