Computer-implemented methods and apparatus are presented for processing data collected by at least two receivers from multiple satellites of multiple Global Navigation Satellite Systems, where at least one GNSS is Frequency Division Multiple Access. A third high frequency power source for superposing a third high frequency power having a frequency lower than that of the first high frequency power and higher than that of the second high frequency power on the first high frequency power. Each rule defines a desired target configuration for a category of subjects. The fixture-support assembly also has a neck portion extending from the proximal end and the neck portion has a flange portion extending from it. Where multiple Paging Channels are used, page attempts are assigned to the appropriate Paging Channel according to a pre-determined service-to-Paging Channel mapping. The organometallic iridium complex is represented by General Formula and has a structure in which a phenyl group whose 2-position and 6-position are each substituted by an alkyl group is bonded to the 4-position of pyrimidine.
