More Information
Summary: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.
