摘要： A system, method, and apparatus according to various embodiments are disclosed herein to enable a signal in space scheme to have improved signal penetration within buildings and other attenuated environments. The disclosed enhanced signal delivery method transmits multiple bursts in a successive pattern that is known by a receiver on the ground. This successive transmission pattern of bursts effectively creates a longer correlation sequence that allows a receiver to more readily be able to pull the signal out of the noise and, thus, allows a receiver located in a more stringent, attenuated environment to receive a signal where it previously was unable to do so.

摘要： A system, method, and apparatus for the authentication of the physical location of a target node are disclosed herein. In one or more embodiments, the authentication of the target node's physical location is achieved by using ping ranging measurements obtained from the amount of time that elapses during ping messages being sent between the target node and at least one trusted node with a known physical location. The physical location of the trusted node(s) is obtained by using satellite geolocation techniques. The accuracy of the ranging measurements may be improved upon by using pre-coordination and/or priority determination of the ping messages being sent between the target node and the trusted node(s). In at least one embodiment, the ping messages are sent by dedicated ping response hardware that is associated with the target node and/or the trusted node(s). In some embodiments, the ping messages include a pseudo random code bit sequence.

摘要： A method, system, and apparatus are disclosed for multipath isolation through the combined use of antenna diversity and frequency diversity. In particular, the present disclosure utilizes antenna diversity and frequency diversity to combat the deleterious effects of reflected signals on the positioning accuracy of satellite navigation systems. In at least one embodiment, the present disclosure uses two antennas and two frequencies for operation with a satellite navigation system. The present disclosure segregates the antennas and frequencies into two classes: references and monitors. The reference measurements are used for estimating the state of the vehicle, and the monitor measurements are used to detect faults that might degrade the reference estimation. Thus, the present disclosure enables an improvement in the positioning error experienced by roving users in downtown and indoor environments. Applications include positive train control, aircraft surface guidance, marine craft navigation in canals and ports, as well as automotive lane keeping.
