Abstract: A method of measuring a satellite signal includes: receiving, at an apparatus, the satellite signal; determining, at the apparatus, a first code phase of the satellite signal, corresponding to a first time period, based on a first portion of the satellite signal that has a first bandwidth; determining, at the apparatus, a second code phase of the satellite signal, corresponding to a second time period, based on a second portion of the satellite signal that has a second bandwidth, where the second bandwidth is larger than the first bandwidth, and where the second time period is separate from the first time period; and determining, at the apparatus, a carrier phase of the satellite signal based on the first portion of the satellite signal and a third portion of the satellite signal that has the first bandwidth and spans the second time period.

Abstract: Techniques are provided for utilizing a mobile device to estimate ionospheric delays in GNSS transmissions. An example method of determining a position of a mobile device includes obtaining a pseudorange measurements and carrier-phase measurements for a satellite at a first frequency band and a second frequency band, determining a bias estimate for the satellite based on a plurality of pseudorange measurements and carrier-phase measurements, determining a delta carrier-phase measurement for the satellite based on the carrier-phase measurements at the first frequency band and the second frequency band, and determining the position of the mobile device based at least in part on the delta carrier-phase measurement, and the pseudorange measurements, the carrier-phase measurements, or both.

Abstract: Techniques described herein leverage MCMF functionality to provide a local RTK solution for a mobile device in which an initial highly-accurate location determination for the mobile device can be leveraged to generate RTK correction information that can be used to make subsequent, highly-accurate location determinations without the need for measurement information from an RTK base station. This RTK correction information can be applied to GNSS measurements taken by the mobile device over a long period of time while retaining the ability to produce highly-accurate location determinations for the mobile device. And additional correction information may be obtained and applied to the RTK correction information to extend this period of time even longer.
