Claim 0:
1. A precision guidance munition assembly for a guided projectile, comprising:
a canard assembly comprising at least one canard coupled to the precision guidance munition assembly, wherein the at least one canard is moveable; and
at least one non-transitory computer-readable storage medium carried by the precision guidance munition assembly having a set of instructions encoded thereon that when executed by at least one processor operates to aid in guidance, navigation and control of the guided projectile, wherein the set of instructions comprise:
select a maneuver envelope that describes a control authority of the guided projectile, wherein the maneuver envelope comprises a plurality of command rings identifying an amount of ground maneuver per second as a function of time, based, at least in part, on a roll angle and a maximum canard deflection;
predict an impact point of the guided projectile relative to a target;
determine a miss distance based on the predicted impact point relative to the target;
determine a maneuver command based on the maneuver envelope; and
apply the maneuver command to move the at least one canard at an optimal time based, at least in part, on the maneuver envelope; and wherein when the maneuver command is applied during a first time interval the range increases and when the maneuver command is applied during a second time interval the range decreases.
