Abstract

The present invention provides a heterogeneous spacecraft network including a network management architecture to facilitate communication between a plurality of operations centers and a plurality of data user communities. The network management architecture includes a plurality of network nodes in communication with the plurality of operations centers. The present invention also provides a method of communication for a heterogeneous spacecraft network. The method includes: transmitting data from a first space segment to a first ground segment; transmitting the data from the first ground segment to a network management architecture; transmitting data from a second space segment to a second ground segment, the second space and ground segments having incompatible communication systems with the first space and ground segments; transmitting the data from the second ground station to the network management architecture; and, transmitting data from the network management architecture to a plurality of data user communities.

First claim

What is claimed is:

1. A heterogeneous spacecraft network comprising:
first and second space segments each having a communication system, the communication systems of the space segments being incompatible with each other, the incompatible communication systems of the space segments do not permit communication between the space segments;
first and second operations centers each having a communication system, the communication system of the first operations center being compatible with the communication system of the first space segment, the communication system of the second operations center being compatible with the communication system of the second space segment, the communication systems of the first and second operations centers being incompatible with each other;
a plurality of data user communities;
a network management architecture to facilitate communication between the first and second operations centers and the plurality of data user communities.

2. The network of claim 1 wherein the network management architecture includes a standardized communication system capable of facilitating communication between the first and second operations centers.

3. The network of claim 2 wherein at least one of the first and second space segment includes a spacecraft, a constellation of spacecraft, a formation flight of spacecraft, or a swarm of spacecraft.

4. The network of claim 3 wherein the standardized communication system of the network management architecture is capable of facilitating communication between the first and second space segments via the first and second operations centers.

5. The network of claim 4 wherein the standardized communication system uses WiFi based on the IEEE 802 family of network standards.

6. The network of claim 5 wherein at least one of the first and second space segments includes a WiFi transceiver.

7. The network of claim 6 wherein the first and second operations centers include a mission operations center and a science operations center.

8. The network of claim 7 wherein the standardized communication system of the network management architecture is capable of facilitating communication between the mission operations center and the science operations center.

9. The network of claim 6 wherein at least one of the first and second operations centers includes a WiFi transceiver.

10. The network of claim 9 wherein the network management architecture facilitates communication between the WiFi transceivers of the at least one of the first and second space segments and the at least one of the mission operations center and the science operations center.

11. The network of claim 6 wherein the at least one of the first and second space segments includes a WiFi transceiver and an S-band transceiver.

12. The network of claim 6 wherein the WiFi transceiver includes a link range between space and ground of 3100 km and includes a link range between space and space of 550 km.

13. A method of communication for a heterogeneous spacecraft network, the method comprising:
transmitting data from a first space segment to a first ground segment;
transmitting the data from the first ground segment to a network management architecture;
transmitting data from a second space segment to a second ground segment, the second space and ground segments having incompatible communication systems with the first space and ground segments;
transmitting the data from the second ground station to the network management architecture; and
transmitting data from the network management architecture to a plurality of data user communities.

14. The method of claim 13 wherein the space segments include a spacecraft, a constellation of spacecraft, a formation flight of spacecraft, or a swarm of spacecraft.

15. The method of claim 14 wherein the ground segments include a mission operations center, a science operations center, or a ground station.

16. A method of communication for a heterogeneous spacecraft network, the method comprising:
transmitting data from a first space segment to a second space segment using WiFi based on the IEEE 802 family of network standards;
transmitting the data from the second space segment to a ground segment using WiFi based on the IEEE 802 family of network standards, the data from the first space segment not being transmitted directly to the ground segment due to incompatible communication systems;
transmitting the data from the ground station to a network management architecture; and,
transmitting the data from the network management architecture to a plurality of data user communities.

17. The method of claim 16 wherein the space segments include a spacecraft, a constellation of spacecraft, a formation flight of spacecraft, or a swarm of spacecraft.

18. The method of claim 17 wherein the ground segments include a mission operations center, a science operations center, or a ground station.
