Document Type and Number:
Japanese Patent JP2014052370
Kind Code:
A
Abstract:

To locate a satellite signal receiver with a flexible number of channels to improve power efficiency and avoid unnecessary power consumption.

A system and a method for locating a satellite signal receiver are disclosed. The system includes a channel opening module, a signal processing module, and a positioning module. The channel opening module is configured for opening a predetermined number of channels on the basis of a priority schedule.
