Claims:

We claim: A geophysical survey system comprising: a remotely piloted vehicle a geophysical sensing payload mounted on the remotely piloted vehicle and ground based control and data receiving means which comprises a separate mobile tracking, communication and control unit and a separate mobile geophysical analysis unit physically separate from said mobile tracking, communication and control unit.

2. A geophysical survey system according to claim 1 wherein the mobile geophysical analysis unit also comprises means for real-time analysis of received geophysical data from said geophysical sensing payload.

3. A geophysical survey system according to claim 2 wherein the mobile geophysical analysis unit also comprises means for processing, interpretation and map display of geophysical data derived from said geophysical sensing payload.

4. A geophysical survey system according to claim 1 wherein said geophysical sensing payload includes a radiometric payload which comprises nuclear detection means.

5. A geophysical survey system according to claim 4 wherein said radiometric payload comprises nuclear scintillation means.

6. A geophysical survey system according to claim 5 wherein said radiometric payload also comprises means for cooling said nuclear scintillation means.

7. A geophysical survey system according to claim 6 wherein said means for cooling comprises thermoelectric means and wherein said nuclear scintillation means are located in a thermally isolated housing.

8. A geophysical survey system according to claim 1 wherein said separate units are interconnected by wireless relays.

9. A geophysical survey system according to claim 1 wherein the ground based control and data receiving means also comprises means for data processing and for guiding flight of said remotely piloted vehicle.

10. A geophysical survey system comprising: a remotely piloted vehicle a geophysical sensing payload mounted on the remotely piloted vehicle ground based control and data receiving means which comprises a separate mobile tracking, communication and control unit and a separate mobile geophysical analysis unit physically separate from said mobile tracking, communication and control unit and wherein the separate geophysical analysis unit includes means for processing, interpretation and map display of geophysical data derived from said geophysical sensing payload.

11. A geophysical survey system according to claim 10 wherein said geophysical sensing payload comprises a bismuth germanium oxide (BGO) type radiometric payload.

12. A geophysical survey system according to claim 10 wherein the mobile geophysical analysis unit also comprises means for real-time analysis of received geophysical data from said geophysical sensing payload.

13. A geophysical survey system according to claim 10 wherein said geophysical sensing payload comprises nuclear detection means.

14. A geophysical survey system according to claim 10 wherein said geophysical sensing payload comprises nuclear scintillation means.

15. A geophysical survey system according to claim 14 wherein said geophysical sensing payload also comprises means for cooling said nuclear scintillation means.

16. A geophysical survey system according to claim 15 wherein said means for cooling comprises thermoelectric means and wherein said nuclear scintillation means are located in a thermally isolated housing.

17. A geophysical survey system according to claim 10 wherein said separate units are interconnected by wireless relays.

18. A geophysical survey system comprising: a remotely piloted vehicle a geophysical sensing payload comprising a radiometric payload mounted on the remotely piloted vehicle and weighing no more than 20 kg and ground based control and data receiving means which comprises a separate mobile tracking, communication and control unit and a separate mobile geophysical analysis unit physically separate from said mobile tracking, communication and control unit.
