Classification: CPC F | IPC F

Claim 0:
1. A flight management system, comprising:
a radio frequency orthogonal interferometry array configured to generate a reference frame projected in the direction of one or more targets having radio frequency orthogonal interferometry waveforms and to further provide radio frequency (RF) communications;
at least one projectile configured to receive the radio frequency orthogonal interferometry waveforms and the RF communications;
a short range guidance system on the projectile configured to provide guidance of the projectile from a hand-off point to the targets; and
a non-transitory computer-readable storage medium carried by the projectile having a set of instructions encoded thereon that when executed by one or more processors, provide guidance and navigation of the projectile, the set of instructions being configured to cause the one or more processors to perform:
processing azimuth and elevation information from the radio frequency orthogonal interferometry waveforms;
processing at least one of range information and mission data from the RF communications;
determining coordinates of the projectile using the azimuth, elevation and range information, wherein the coordinates are relative to the radio frequency orthogonal interferometry array;
guiding the projectile along a trajectory within the reference frame to the hand-off point;
switching to the short range guidance system at the hand-off point; and
guiding the projectile from the hand-off point to the targets using a ballistic guidance or glide slope.
