摘要： A method for selecting a global positioning receiver includes receiving global positioning system signals from global positioning system receivers. The global positioning system receivers receive the global positioning system signals from corresponding global positioning system satellites. The method also includes replicating the global positioning system signals from the global positioning system receivers, determining a signal drift and a phase precision for each global positioning system signal, and selecting one of the global positioning system signals based on the corresponding signal drift and the phase precision of the global positioning system signal.

摘要： A signal distribution system includes global positioning system receivers in communication with optical line terminals and a system manager. Each global positioning system receiver receives a signal from a corresponding global positioning system satellite. Each optical line terminal includes a management card and a line card. The management card receives a signal from a corresponding global positioning system receiver. Each line card receives a signal from each management card and determines a signal drift and a phase precision for each signal. The system manager receives a failure communication for a global positioning system signal from a line card when the signal drift of the global positioning system signal is above a threshold signal drift or the phase precision of the signal is below a threshold phase precision. The system manager identifies a failure location of the signal within the system based on one or more received failure communications.

摘要： A mobile platform includes an antenna adapted to simultaneously transmit on a first channel and receive on a second channel, and to dynamically switch communication channels as needed. For example, as the mobile platform changes position, orientation, etc., the configuration of the antenna may be updated to transmit on the second channel and receive on the first channel. Accordingly, despite changes in position or orientation, the mobile platform may maintain communication with other mobile platforms, ground controllers, user equipment, etc.

摘要： A cascaded distribution framework includes a global positioning system receiver in communication with optical line terminals. Each global positioning system receiver receives a signal from a corresponding global positioning system satellite. Each optical line terminal includes a management card for each global positioning system receiver in communication with the optical line terminal and a line card. The management card receives a global positioning system signal from a corresponding global positioning system receiver. The line card is collocated for each management card in the optical line terminal. Each line card receives a global positioning system signal from each management card in the optical line terminal, determines a signal quality score of each received signal based on a signal drift and a phase precision of the corresponding signal, and selects one of the received global positioning system signals having the highest signal quality score.
