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.

摘要： A system and methods for reducing navigation satellite receiver power usage are presented. A wireless signal is received at a portable electronic device in a signal environment. At signal characteristic of the wireless signal at the portable electronic device is measured in the signal environment. An estimated signal strength of the wireless signal in the signal environment is estimated based on the signal characteristic. The estimated signal strength is compared to an expected signal strength of the wireless signal to calculate an estimated signal-strength-change relative to the expected signal strength. A GNSS signal is tracked at the portable electronic device, if the estimated signal-strength-change indicates an expected GNSS signal attenuation is lower than a signal attenuation threshold. The tracking of the GNSS signal is reconfigured at the portable electronic device, if the expected GNSS signal-strength-change indicates the expected GNSS signal attenuation is greater than the signal attenuation threshold.
