Abstract

An antenna stowage and deployment system, including a spacecraft and at least one pair of adjacent nesting antenna assemblies. Each of the antenna assemblies further includes an articulating deployment couple affixed to the spacecraft for deploying the antenna assembly, a first antenna affixed to the deployment couple, and a second antenna affixed to the first antenna. The enhanced antenna stowage and deployment system according to the present invention permits the separation and orientation of more than two adjacent antennas which require an extremely precise deployed position relative to a main spacecraft body. As such, the deployment couple further includes a 1-axis separating hinge and/or a 2-axis primary deployment gimbal. At least one of the antenna assemblies further includes a 2-axis secondary deployment gimbal or a rigid connecting structure for affixing the second antenna to the first antenna.

Claims

1. An antenna stowage and deployment system, comprising:

a spacecraft;

at least a first and a second antenna assembly, wherein the at least first antenna assembly and the second antenna assembly are located along the same surface of said spacecraft, and wherein, in a non-deployed state, the second antenna assembly is configured to nest upon the first antenna assembly, each of said antenna assemblies further comprising;

an articulating deployment couple affixed to said spacecraft for deploying said antenna assembly,

a first antenna affixed to said deployment couple, and

a second antenna affixed to said first antenna.

2. An antenna stowage and deployment system according to claim 1, wherein said deployment couple further comprises a 1-axis separating hinge and/or a 2-axis primary deployment gimbal.

3. An antenna stowage and deployment system according to claim 1, wherein at least one of said antenna assemblies further comprises a 2-axis secondary deployment gimbal for affixing said second antenna to said first antenna.

4. An antenna stowage and deployment system according to claim 1, wherein at least one of said antenna assemblies further comprises a rigid connecting structure for affixing said second antenna to said first antenna.

5. An antenna stowage and deployment system according to claim 1, wherein at least one of said antenna assemblies further comprises a third antenna affixed to said second antenna.

6. An antenna stowage and deployment system according to claim 5, wherein said third antenna comprises a center-fed antenna.

7. An antenna stowage and deployment system according to claim 5, wherein the at least one of said antenna assemblies further comprises a 2-axis tertiary deployment gimbal for affixing said third antenna to said second antenna.

8. An antenna stowage and deployment system according to claim 1, wherein said first antenna further comprises a reflector.

9. An antenna stowage and deployment system according to claim 1, wherein said first antenna further comprises an active array.

10. An antenna stowage and deployment system according to claim 1, wherein said first antenna further comprises a center-fed antenna.

11. An antenna stowage and deployment system according to claim 1, wherein said second antenna further comprises a reflector.

12. An antenna stowage and deployment system according to claim 1, wherein said second antenna further comprises an active array.

13. An antenna stowage and deployment system according to claim 1, wherein said second antenna further comprises a center-fed antenna.

14. An antenna stowage and deployment system according to claim 1, wherein said at least first and second antenna assemblies utilizes common launch restraints.
