Abstract: Common view time transfer and related apparatuses and methods are disclosed. An apparatus includes a receiver oscillator to provide a local clock signal and one or more processors. The one or more processors are to perform, at least partially based on the local clock signal, event time tagging pre-processing at least partially responsive to satellite signals received from one or more satellites to generate a decimated precision correction state estimate; determine, per satellite signal pseudo range residuals; determine a navigation engine clock state; perform a precision clock state pre-processing operation at least partially responsive to the navigation engine clock state and the decimated precision correction state estimate to generate a precision navigation clock state; and generate a common view real time report at least partially responsive to the per satellite signal pseudo range residuals and the precision navigation clock state.
