摘要： A system within a multi-channel GPS receiver that searches for Global Positioning System (GPS) satellites by receipt of a plurality of GPS signals where each GPS signal corresponds to a GPS satellite having a GPS satellite identification number (ID) is shown. The system may include a controller in control of the multi-channel GPS receiver that assigns each GPS satellite ID that corresponds to each of the plurality of GPS signals received by the multi-channel GPS receiver to an individual channel of the multi-channel GPS receiver and a monitoring channel selected by the controller from the multi-channel GPS receiver that monitors the received GPS signal.
摘要翻译：示出了多通道GPS接收机内的系统，其通过接收多个GPS信号来搜索全球定位系统（GPS）卫星，其中每个GPS信号对应于具有GPS卫星识别号码（ID）的GPS卫星。该系统可以包括控制多通道GPS接收器的控制器，其将与由多通道GPS接收机接收的多个GPS信号中的每一个对应的每个GPS卫星ID分配给多频道GPS接收机的单独信道以及由监视所接收的GPS信号的多通道GPS接收器由控制器选择的监视通道。

摘要： An apparatus and method for merging a disjoint pair of maps comprising a digital building map that includes a floor plan and an access point (AP) map that includes identifiers for a plurality of access points is presented. In some embodiments, a first trajectory plot, of a mobile device, relative to the AP map, is received and a plurality of hypotheses is set, where each hypothesis defines a unique translation between the AP map and the building map. A plurality of costs may be computed for the first trajectory, where each cost of the first trajectory corresponds to a distinct hypothesis in the plurality of hypotheses. The hypothesis where the first trajectory has the lowest cost relative to the other hypotheses may be selected.
