Abstract: To facilitate crew coordination and interaction using portable electronic data storage and display devices, automated and interactive capabilities allow any of several crew members to forward information regarding a page of data which the crew member has selected using the user interface of his or her portable electronic data storage and display device to the portable electronic data storage and display device of any other crew member or all other crew members particularly those who, due to task loading, may be unable to immediately employ the data manipulation and control functions resident in their own portable electronic data storage and display device. Data thus displayed is available for independent or interactive manipulation as though it had been locally rather than remotely selected.

Abstract: Dynamic aircraft/vehicle specific load planning and weight balancing systems and methods are used to automate the process of weighing passengers and their baggage, including carry-on baggage, to accurately and quickly determine the passenger and passenger baggage location on a specific aircraft/vehicle to generate an efficient and precise aircraft load plan and provide data to determine loaded aircraft weight and balance. Digital scale(s) and passenger ticket/boarding pass scanner(s) are used to acquire the weight and location data, which can be fed to a processor to process the data to determine appropriate weight and balance for each flight and/or transmit data to other systems to be included in their determination of vehicle weight and weight distribution/balance.

Abstract: A differential GNSS ground station is disclosed which generates and broadcasts highly veracious GNSS satellite differential correction data suitable for use in the landing of aircraft. In this context, "veracious` includes the qualities of both accuracy and integrity wherein the broadcast differential correction data is corrupted by a lower level of errors than is customary for the current state of the art and the broadcast differential correction data includes reliable estimates of the noise errors and bias errors corrupting the differential corrections for each GNSS satellite signal. The ground station comprises at least two independent GNSS satellite signal receivers, a processing apparatus for collecting and processing information from the at least two independent GNSS receivers, and a transmitter for broadcasting the composite DGNSS correction signals over a distance.

Abstract: A portable attitude determination apparatus and method are disclosed that can be used with a ship docking system. At least two receivers on a vessel receive Global Positioning System (GPS) satellite data. GPS carrier phase measurements are used to determine attitude (i.e., roll, pitch and yaw angles) of a moving platform. The phase measurements are processed to determine a precise vector from one receiver phase center to the other. The azimuth and elevation of a baseline vector is then computed. Float ambiguities between the two receivers are determined, and are used to provide initial estimates of antenna baseline length and attitude. A search procedure is then employed to find the actual integer ambiguities. Only GPS observables are needed; no other external data input is required.

Abstract: The invention provides an efficient, broadband, antenna system for RF communications. The benefits of the invention include: a single integrated system for total band coverage; high system efficiency across the operating band; multiple instantaneous transmit and receive signal capability; and simple mechanical assemblies. The invention includes various configurations of multiple transceivers connected to a set of RF filters and associated impedance matching networks which are used to excite a plurality of trapped antenna elements. The new antenna system, offers control over the antenna's directivity and the antenna's driving point impedance by using sub-band systems as defined by a series of RF filters and traps which divide the physical antenna elements into various radiating lengths. Continuous coverage over the entire frequency band of interest is achieved by using different physical antenna elements for adjacent sub-bands.
