Guidance was planned to be provided during mid-course flight by an inertial navigation system, while terminal guidance would use a dual-mode seeker . which was planned to use Shelldyne-H fuel.
42.
It is based on terminal guidance system technology, which improves warhead accuracy by firing small thrusters to adjust the warhead's trajectory and uses satellite navigation systems to help find the target.
43.
The Seekbat was based on the AGM-78 Standard ARM . It had a larger propulsion unit and used semi-active radar homing with an infrared seeker for terminal guidance of the missile.
44.
Terminal guidance in the target area was provided by the optical Digital Scene Matching Area Correlation ( DSMAC ) system, which compared a stored image of target with the actual target image.
45.
This study was led in conjunction with two other studies . " Rendezvous Study " performed by MIT Instrumentation Laboratories, and " Earth Terminal Guidance and Lunar Landing ", by ITT Laboratories.

"Your Marines would be more in an ` area coverage'and they would be capable of providing not only terminal guidance to our aircraft but, in fact, on closing with and killing the enemy,"
47.
The missile is guided by proportional navigation to the approximate impact point, before switching to a terminal guidance mode that attempts to steer the missile to the most vulnerable point of the target.
48.
Terminal guidance can be done with active radar homing, passive radar or Electronic warfare support measures, infrared homing or optical guidance, or the ( fixed ) target was predesignated with as final waypoint.
49.
Terminal guidance used active radar homing, with a small radar set fitted in the nose of the missile, with the missile's warhead being detonated by a proximity fuse, a backup impact fuze also being fitted.

Experience during Operation Enduring Freedom and Operation Iraqi Freedom led US air power planners to seek additional capabilities in one package, resulting in ongoing program upgrades to place a precision terminal guidance seeker in the JDAM kit.
