Abstract: An apparatus for interrogating a media to be analyzed, such as an avian egg, is provided. Such an apparatus includes an emitter assembly configured to emit light toward a media. The emitter assembly has a first emitter source configured to emit a first light signal and a second emitter source configured to emit a second light signal. The first and second light signals are transmitted through the media in phase quadrature. A detector assembly is configured to detect the first and second light signals transmitted through the media. The detector assembly is further configured to resolve a relative or absolute amplitude of each of the first and second light signals. A processor is configured to process the detected signal to identify a property of the media using at least one of the relative and absolute amplitudes of the first and second light signals. An associated method is also provided.

Abstract: Methods and systems are provided for determining a position of a mobile terminal that includes a satellite radiotelephone and a global positioning system (GPS) receiver based on knowledge of the position of the communication satellite spot-beam in which the mobile terminal is located. Using knowledge of the location of the communication satellite spot-beam, the present invention can resolve the one-millisecond ambiguity, that typically arises from the code repeat length where relative code phase may be determined but absolute code phase (i.e. one millisecond increments) could be off by one or more code periods. The spot-beam identifier is obtained from the satellite communication system and used to determine the geographic location of the spot-beam. Trial positions, i.e., candidate mobile terminal positions, are then selected to cover the spot-beam area, with spacing between trial positions provided to account for the one-millisecond ambiguity.
