Simple geolocation (currently supporting 90 and 30
meter positioning accuracy) could be sufficient for general
orientation but will not be suitable for targeting of GPS guided
weapons, such as JDAM. This level of accuracy is yet to be provided by
unmanned systems. At present, the US Air Force is operating systems
such as the Gridlock advanced concept technology demonstrator,
integrated with the Global Hawk system. Gridlock uses a high precision
navigation system generating a digital terrain database with 10 meter
accuracy. Even these levels of accuracy are insufficient for precision
engagement by unmanned systems - future unmanned combat systems will
be required to deliver targeting accuracy of 1 – 3 meters.
Accurate location is not the only factor needed for precision
engagement - cruise missiles, and EO guided weapons such as Storm
Shadow, Taurus 350 and SPICE requires precise and detailed imagery for
navigation and terminal guidance. Live video is required for "man in
the loop" control of guided weapons, such as Hellfire and SPIKE, to
avoid fratricide and collateral damage. Users requiring such live
imagery can link directly to the sensor, using "tactical video
receiver" which receives analog video streams. UAV images can be
shared by multiple users, including helicopter pilots, field
commanders as well as dismounted troops. More advanced systems enable
active control of the payload.
