In one embodiment, a method of performing navigation includes receiving a LEO signal from a LEO satellite, decoding a navigation signal from the LEO signal, receiving first and second ranging signals from first and second ranging sources, respectively, determining calibration information associated with the first and second ranging sources, and calculating a position using the navigation signal, the first and second ranging signals, and the calibration information. In another embodiment, a method of providing a LEO signal from a LEO satellite includes providing a plurality of transmit channels over a plurality of transmit slots, where the transmit channels comprise a set of communication channels and a set of navigation channels, generating a first pseudo random noise (PRN) ranging overlay corresponding to a navigation signal, applying the first PRN ranging overlay to a first set of the navigation channels, and combining the communication channels and the navigation channels into a LEO signal. The method also includes broadcasting the LEO signal from the LEO satellite. A low earth orbit (LEO) satellite data uplink is also provided. A method includes broadcasting the data uplink signal to the LEO satellite. Various approaches to localized jamming of navigation signals are further provided. Modulated noise signals are broadcast over an area of operations to provide a plurality of jamming bursts corresponding to the navigation signal. The jamming bursts are configured to substantially mask the navigation signal in the area of operations.

摘要： A navigation system provides a significant level of protection against all forms of interference or jamming to GPS in a cost-effective way. The system employs a network of ground reference stations and Low Earth Orbiting (LEO) satellites in conjunction with GPS. A common-view ranging geometry to a GPS satellite is established that links a reference station and a user. A second common-view geometry to a LEO satellite between the same reference station and user pair is also established. The ground stations synthesize real-time aiding signals by making carrier phase measurements of GPS the LEO satellite signals. This aiding information is transmitted via the LEO satellites to the user receiver at high power to penetrate ambient jamming. The user receiver locks onto the carrier phase of the LEO satellite, demodulates the aiding information, then applies the carrier phase measurements and the aiding information to enable extended coherent measurements of the GPS signals. The system thereby recovers the GPS signals that would otherwise be lost to the jamming.

摘要： Methods and systems for navigation are disclosed. In one embodiment, data from GPS satellites within a field of view of a ground station are retransmitted to LEO satellites, such as Iridium satellites, and cross-linked if necessary before being transmitted to a user. The user is then able to combine the fed-forward data with data received directly from GPS satellites in order to resolve errors due to interference or jamming. Alternately, a method includes receiving at least one carrier signal at a user device, each carrier signal being transmitted by a distinct LEO satellite. The user device processes the carrier signals to obtain a first carrier phase information. The user device recalls an inertial position fix derived at an inertial reference unit. The user device derives a position of the user device based on the inertial position fix and the first carrier phase information.
