Abstract: A method of code phase correlation and apparatus (10 to 15) implementing the same is disclosed, the method comprising the steps of (a) receiving a subject signal comprising a target pseudorandom noise code; (b) generating early and late replica code signals corresponding to the target code; (c) correlating the subject signal with the early and late replica code signals and returning respective early and late correlation values; and (d) calculating a code phase discriminator for determining whether the target code has been acquired as a function of the sum of the early and late correlation values.

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 unit (1) is disclosed for use with a cellular radio transmission system in the form of a plurality of base stations (BS1 to 7) adapted for two-way radio communication and situated at respective geographical locations to define a corresponding plurality of overlapping service areas (SA1 to 7) constituting one or more regions. The mobile unit comprises a receiver (5), control means (2) for controlling the mobile unit and a user interface (6, 9, 10) wherein the control means is adapted whereby, in use and having pre-programmed the control means with information identifying a predetermined service area, the control means recognizes entry of the mobile unit into that service area from an adjacent service area and notifies a user of the mobile unit of said entry via the user interface. The mobile unit may further comprising a transmitter (5) and be adapted to communicate by two-way radio with the base stations. The user may be notified with an audible, visible or mechanical alarm by the user interface.
