Abstract: GPS receiver (1) is disclosed together a mobile unit especially in the form of a mobile cellular telephone (30) incorporating the same. The GPS receiver (1) comprises a GPS signal antenna (10) for receiving externally transmitted GPS signals; an analogue-to-digital converter (11) coupled to the antenna for sampling the received GPS signals; a memory (12) for storing the GPS signal samples; and a digital GPS signal processor (13, 14) for retrieving pseudorange information from the GPS signal samples stored in the memory (12). The receiver (1) has a dormant mode of operation in which received GPS signals are sampled and stored in the memory (12) but the signal processor (13, 14) is not operative for retrieving pseudorange information, and an active mode of operation in which the signal processor (13, 14) is operative for retrieving pseudorange information. Also, the receiver (1) is arranged to change from the dormant mode to the active mode in response to a instruction received from external to the receiver (1) and made whilst the receiver (1) is operating in the dormant mode.

Abstract: A mobile cellular telephone (100) is disclosed comprising a communications transmitter (103) and receiver (102) arranged for two-way communication with a base station (BS), and a GPS receiver (105, 106) arranged to power up in response to direct interaction between a user and the mobile phone (100) after the telephone has been switched on. In particular, the GPS receiver (105, 106) may be arranged to power up in response to the user making a call to the emergency services. Recognition by the telephone of an emergency call being made may occur when the user enters the emergency call telephone number, or one or more, but not all of the digits of the emergency call telephone number.
