摘要： A variety of methods and devices for a low-probability of intercept, low probability of denial (LPI/LPD) method of providing RF signals in denied spaces are disclosed. A phased array antenna converts an omnidirectional communication system into a highly directional system. This factor coupled with the precise timing between the transmit and receive sets, establishes a precise distance measurement between the two sets. Using three or more transceivers enables the composition of an ad hoc network of nodes that can be used to establish an available mesh of position and timing that can be accessed by operators within the radio boundaries of the mesh. Portable transceivers reestablish position, navigation and timing (PNT), thereby forming an ad-hoc network. Where the ad-hoc network PNT mesh can intersect with a GPS signal that is outside of the denied environment, the ad-hoc network mesh can detect the GPS position and timing.
