Abstract

Apparatus for management of communications resources of a moving platform comprising a communications system configured to effect wireless data communication between the moving platform and a recipient node, the communications resources comprising a plurality of wireless communications links for facilitating the wireless data communication and a plurality of antennas associated therewith, the apparatus comprising an antenna analysis and selection module residing with the communications system and configured to:
identify a communications requirement between the moving platform and a recipient node; receive attribute data representative of movement of the platform, the attribute data including platform movement data comprising future known movement of the moving platform and/or future predicted movement of the moving platform and/or the recipient node; determine, using the attribute data, suitability of each of a plurality of antennas and/or portions of aperture antenna for data transmission from the moving platform to the recipient node; determine a quality metric for each of a plurality of antennas/portions of aperture antenna, the quality metric being indicative of a respective performance criterion; and select one or more of the suitable antennas/portion of aperture antenna having a highest performance criterion, for the data transmission.

First claim

1 . An apparatus for management of communications resources of a moving platform comprising a communications system configured to effect wireless data communication between said moving platform and a recipient node, said communications resources comprising a plurality of wireless communications links for facilitating said wireless data communication and a plurality of antennas associated therewith, the apparatus comprising an antenna analysis and selection module residing with said communications system and configured to:
identify a communications requirement between said moving platform and a recipient node; receive attribute data representative of movement of said platform, said attribute data including platform movement data comprising future known movement of said moving platform and/or future predicted movement of said moving platform and/or said recipient node; determine, using said attribute data, suitability of each of a plurality of antennas and/or portions of aperture antenna for data transmission from said moving platform to said recipient node; determine a quality metric for each of a plurality of antennas/portions of aperture antenna, said quality metric being indicative of a respective performance criterion; and select one or more of said suitable antennas/portion of aperture antenna having a highest performance criterion, for said data transmission.

2 . The apparatus according to claim 1 , configured to determine, by estimating a quality if a respective resultant communications link, said suitability of each of a plurality of antennas and/or portions of aperture antenna for data transmission from said moving platform to said recipient node.

3 . The apparatus according to claim 1 , wherein said attribute data includes data representative of emissions control criteria associated with said moving platform and/or said recipient node.

4 . The apparatus according to claim 3 , configured to determine said suitability of each of a plurality of antennas and/or portions of aperture antenna for data transmission from said moving platform to said recipient node by determining, for each said antenna/portion of antenna aperture, whether or not data transmission thereby to said recipient node will adhere to said emissions control criteria.

5 . The apparatus according to claim 1 , configured to receive, during mission execution, platform movement data from a system/subsystem and/or function of said moving platform.

6 . The apparatus according to claim 3 , configured to receive, during mission execution, attribute data representative of emissions control restrictions.

7 . The apparatus according to claim 1 , wherein said platform movement data comprises position and/or attitude data associated with said moving platform and received from one or more systems/subsystems and/or functions of said moving platform.

8 . The apparatus according to claim 7 , wherein said attribute data includes route and/or manoeuvre and/or trajectory data.

9 . The apparatus according to claim 5 , wherein said quality metric is representative of antenna gain characteristic of a respective antenna, based on moving platform position and/or attitude.

10 . The apparatus according to claim 5 , wherein said attribute data includes data representative of emissions control criteria associated with said moving platform and/or said recipient node, the apparatus being configured to receive, during a mission from one or more systems/subsystems and/or functions of said moving platform, attribute data representative of said emissions control criteria, said attribute data comprising (i) location data representative of a specified emissions control region, and/or (ii) position and/or attitude and/or velocity data representative of an adversary node defining an emissions control region.

11 . The apparatus according to claim 1 , wherein said attribute data includes data representative of current movement of said moving platform.

12 . The apparatus according to claim 1 , configured to obtain (i) data representative of a location of a fixed recipient node with respect to said moving platform, or (ii) data representative of position and/or attitude and/or velocity of a mobile recipient node with respect to said moving platform; and to:
determine a direction of said moving platform relative to said fixed/mobile recipient node; determine an antenna pointing loss of each said antenna/portion of aperture antenna at said recipient node and/or said moving platform; and calculate a quality metric for each said antenna/portion of aperture antenna based on said pointing loss(es) or a performance metric based on said pointing loss.

13 . The apparatus according to claim 1 , wherein said quality metric is indicative of antenna availability and/or preference and/or compatibility.

14 . The apparatus according to claim 5 , wherein said attribute data includes data representative of emissions control criteria associated with said moving platform and/or said recipient node, configured to identify one or more suitable antennas or portions of aperture antenna from a plurality of antenna resources by (i) determining a location or position of an emissions control region; (ii) determining orientation of said moving platform relative to an emissions control region; (iii) obtaining modified antenna pointing data in respect of a specified antenna or portion of aperture antenna; (iv) determining if wireless data transmission via said antenna or portion of aperture antenna will violate said emissions control region; and calculating a quality metric for each said antenna or portion of aperture antenna of said moving platform relative to an emissions control region.

15 . A method for management of communications resources of a moving platform comprising a communications system configured to effect wireless data communication between said moving platform and a recipient node, said communications resources comprising a plurality of wireless communications links for facilitating said wireless data communication and a plurality of antennas associated therewith, the method comprising using an antenna analysis and selection module residing with said communications system to:
identify a communications requirement between said moving platform and a recipient node; receive attribute data representative of movement of said platform, said attribute data including platform movement data comprising future known movement of said moving platform and/or future predicted movement of said moving platform and/or said recipient node; determine, using said attribute data, suitability of each of a plurality of antennas and/or portions of aperture antenna for data transmission from said moving platform to said recipient node; determine a quality metric for each of a plurality of antennas/portions of aperture antenna, said quality metric being indicative of a respective performance criterion; and select one or more of said suitable antennas/portion of aperture antenna having a highest performance criterion, for said data transmission.
