Embodiment Construction

[0013] Certain terms are used in the description and claims to refer to particular elements. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. The "comprising" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described that the first device is coupled to the second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means.

[0014] Please refer to FIG. 1 , which shows a block dia...

Abstract

A global navigation satellite system (GNSS) receiver system includes a first mobile GNSS receiver and a second mobile GNSS receiver. The first mobile GNSS receiver includes: a first receiver logic for receiving satellite signals and determining positioning related information according to the satellite signals; a data provider logic for providing at least an assisted data according to the positioning related information; and a first communication interface for outputting the assisted data. The second mobile GNSS receiver includes a second communication interface, for communicating with the first communication interface to receive the assisted data from the communication interface; a data collector logic for collecting assisted information from the assisted data; and a second receiver logic for determining positioning information of the second mobile GNSS receiver according to the assisted information and satellite signals.

Description

technical field [0001] The present invention relates to determining the location of an electronic device, and more particularly, to a Global Navigation Satellite System (GNSS) receiver system and associated method for using assistance data received from at least one adjacent GNSS receiver ( assisted data) and satellite signals from GNSS satellites to determine the positioning information of the GNSS receiver. Background technique [0002] With the rapid development of today's personal mobile communication devices, the mobile communication devices can support many value-added services. In particular, some countries mandate the use of some positioning services, for example, GPS functions in mobile phones, to provide users with positioning-related services. In general, the GPS receiver on the ground needs to search for satellites visible in the open sky (open sky) after a cold start (cold start) to collect ephemeris (ephemeris) from the tracked satellites . However, this sea...
