Abstract
Processes and device configurations are provided for extracting observables from communications signals. Methods include performing a frequency extraction on received communication signals to determine a carrier frequency, acquiring an estimation of channel frequency response and a frame start time. Signal tracking is performed to update frame start time of a signal physical broadcast channel block structure (SS/PBCH) in the communication signal, and at least one observable is extracted from the communications signal based on the updated estimate of frame start time. Characteristics of communications signal, such as frame structure including a synchronization signal physical broadcast channel block structure (SS/PBCH) may be used to opportunistically extract time of arrival (TOA) from communications signals. Symbols and subcarriers of new radio signals may be used to extract reference signals, and to determine one or more navigation observables based on communication signal.
