A system and methods for resolving integer cycle ambiguity in medium wave carrier radio signals are presented. A satellite signal is received at a receiving location and a measured code phase of the satellite signal is measured. A satellite location estimate of the receiving location is computed based on the measured code phase. Medium wave radio carrier signals from medium wave radio transmitters are received at the receiving location. A number of wavelengths of the medium wave radio carrier signals from the satellite location estimate to each of the medium wave radio transmitters is determined respectively. A carrier phase of each of the medium wave radio carrier signals is measured. An improved position estimate of the receiving location is computed based on the number of wavelengths and the carrier phase of each of the medium wave radio carrier signals, and a location of each of the medium wave radio transmitters.

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.

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.
