Abstract
This invention provides methods for a GPS device to resolve timing errors as applicable to a AGPS navigation solution, and, in particular, to solutions involving GNSS positioning and timing with limited assistance such as indoors or in a heavily obscured location, where the time of transmit of satellite signals is not directly extractable from the navigation message data. In particular the invention concerns the reconstruction of time-of-transmit from the course acquisition code of weak signals or where assisted-GNSS are employed.
