    Abstract: The present technology relates to a mobile terminal, an information processor, an information processing method, and a program capable of synchronizing time with high precision even in a case where the number of satellites that can be captured is small. In a case where the number of satellites that can be captured is less than a predetermined number, a mobile terminal of one aspect of the present technology does not perform positioning, and generates and outputs, from a positioning unit, pulse signals at predetermined intervals synchronized with a time of the satellite that can be captured, on the basis of information from the satellite. The mobile terminal then maintains time synchronization of wireless communication with an external device of a wireless communication unit with reference to the pulse signal, and performs the wireless communication. The present technology can be applied to terminals equipped with a positioning function based on GNSS and a wireless communication function such as LPWA.
