Abstract

A field unit and ground station may use commercial off-the-shelf (COTS) components and share a common architecture, where differences in functionality are governed by software. The field units and ground stations may be easy to deploy, relatively inexpensive, and be relatively easy to operate. A novel file system may be used where datagrams of a file may be stored across multiple drives and/or devices. The datagrams may be received out of order and reassembled at the receiving device.

First claim

The invention claimed is:

1. A portable apparatus, comprising:
at least one hardware board configured to enable operation of the portable apparatus as a field unit and a ground station, wherein
software controls whether the portable apparatus operates as a field unit or a ground station without physical modification to the at least one hardware board,
when the portable apparatus is operating as a field unit, the portable apparatus collects data and transmits the collected data to at least one space vehicle, and
when the portable apparatus is operating as a ground station, the portable apparatus provides command and control capabilities to the at least one space vehicle.

2. The portable apparatus of claim 1 , wherein the at least one hardware board comprises:
an analog radio board configured to send and receive radio signals via an antenna;
a digital radio board configured to interface with the analog radio board and provide digital radio functionality;
a microcontroller board configured to provide processing for the portable apparatus; and
a backplane that connects the analog radio board, digital radio board, and microcontroller board, facilitating communication between the boards.

3. The portable apparatus of claim 1 , further comprising:
a protective enclosure configured to provide protection from weather.

4. The portable apparatus of claim 1 , wherein the software controlling whether the portable apparatus operates as a field unit or a ground station is stored on an external storage device that can be plugged into the portable apparatus, which then reads and executes the stored software.

5. The portable apparatus of claim 1 , further comprising:
hardware configured to enable wired or wireless communication, wherein
the hardware downloads the software to enable operation of the portable apparatus as a field unit or a ground station.

6. The portable apparatus of claim 1 , wherein encryption keys enabling security privileges on a per-user basis are stored on the portable apparatus and used by the software.

7. The portable apparatus of claim 1 , wherein the portable apparatus is configured to control orientation of an antenna via a rotor control box, and to send data to and receive data from the at least one space vehicle via a transceiver box.

8. The portable apparatus of claim 1 , wherein the portable apparatus is integrated with a rotor of an antenna.

9. A portable field unit/ground station (FU/GS) box, comprising:
an analog radio board configured to send and receive radio signals via an antenna;
a digital radio board configured to interface with the analog radio board and provide digital radio functionality;
a microcontroller board configured to provide processing for the portable FU/GS box; and
a backplane that connects the analog radio board, digital radio board, and microcontroller board, facilitating communication between the boards, wherein
software controls whether the portable FU/GS box operates as a field unit or a ground station without physical modification to the boards,
when the portable apparatus is operating as a field unit, the portable FU/GS box collects data and transmits the collected data to at least one space vehicle, and
when the portable FU/GS box is operating as a ground station, the portable FU/GS box provides command and control capabilities to the at least one space vehicle.

10. The portable FU/GS box of claim 9 , further comprising:
a protective enclosure configured to provide protection from weather.

11. The portable FU/GS box of claim 9 , wherein the software controlling whether the portable FU/GS box operates as a field unit or a ground station is stored on an external storage device that can be plugged into the portable FU/GS box, which then reads and executes the stored software.

12. The portable FU/GS box of claim 9 , further comprising:
hardware configured to enable wired or wireless communication, wherein
the hardware downloads the software to enable operation of the portable FU/GS box as a field unit or a ground station.

13. The portable FU/GS box of claim 9 , wherein encryption keys enabling security privileges on a per-user basis are stored on the portable FU/GS box and used by the software.

14. The portable FU/GS box of claim 9 , wherein the portable FU/GS box is configured to control orientation of an antenna via a rotor control box, and to send data to and receive data from the at least one space vehicle via a transceiver box.

15. The portable FU/GS box of claim 9 , wherein the portable FU/GS box is integrated with a rotor of an antenna.

16. A portable system, comprising:
at least one field unit configured to collect data and transmit the collected data to at least one space vehicle; and
at least one ground station configured to provide command and control capabilities to the at least one space vehicle, wherein
the at least one field unit and the at least one ground station have common hardware.

17. The portable system of claim 16 , wherein software controls whether the at least one field unit and the at least one ground station operate as a field unit or a ground station.

18. The portable system of claim 16 , wherein each of the at least one field unit and the at least one ground station comprises:
an analog radio board configured to send and receive radio signals via an antenna;
a digital radio board configured to interface with the analog radio board and provide digital radio functionality;
a microcontroller board configured to provide processing for the field unit or ground station; and
a backplane that connects the analog radio board, digital radio board, and microcontroller board, facilitating communication between the boards.

19. The portable system of claim 16 , wherein each of the at least one field unit and the at least one ground station comprises:
a protective enclosure configured to provide protection from weather.

20. The portable system of claim 16 , wherein at least one of the at least one field unit and/or the at least one ground station is configured to control orientation of an antenna via a rotor control box, and to send data to and receive data from the at least one space vehicle via a transceiver box.
