Abstract: A mobile device synchronously scans different terrestrial networks for positioning measurements to align the scans in time. With minimal time difference between the scans, the positioning measurements from the different terrestrial networks may be used for crowdsourcing or position determination. The mobile device may synchronously scan a wireless wide area network (WWAN) and a local area wireless network so that positioning measurement derived from the scans are aligned in time. A local area wireless network is, e.g., a wireless local area networks (WLANs) or wireless personal area network (WPANs) but does not include cellular networks or satellite networks. The scans may be scheduled at a hardware level to ensure tight synchronization with near-zero time difference between the scans. Alternatively, the scans may be synchronized at a software level with only scans that occur within a time difference threshold from each other are used for crowdsourcing or positioning.
