摘要： A Low Earth Orbiting (LEO) satellite is used for broadcasting differential navigation corrections. Using LEO satellites, the “footprint” of the beam is much smaller than for geosynchronous satellites. Datalink bandwidth requirements are reduced to sufficiently cover an entire footprint area. With a LEO satellite transmitting in multiple beams, these footprints become even smaller. Corrections targeted to such a small area provide local area corrections broadcast from the LEO satellites. Payment, discounts, subsidies or charges are arranged to encourage different entities to own or host base stations, resulting in wide distribution of the network of base stations for use with satellite communications.

摘要： A system and method for verifying and/or geolocating network nodes in a network in attenuated environments for cyber and network security applications are disclosed. The system involves an origination network node, a destination network node, and at least one router network node. The origination network node is configured for transmitting a data packet downstream to the destination network node through at least one router network node. The data packet contains a header portion and a payload data portion. At least one of the network nodes is an enabled network node. The enabled network node(s) is configured to verify any of the network nodes that are located upstream from the enabled network node(s) by analyzing the header portion and/or the payload data portion of the data packet.

摘要： A system, method, and apparatus for contextual-based virtual data boundaries are disclosed herein. In particular, the present disclosure relates to improvements in access control that work to restrict the accessibility of data based on assigning contextual data thresholds that create a virtual boundary. Specifically, the disclosed method involves assigning at least one threshold to at least one contextual criterion. The method further involves determining whether contextual information from the claimant meets at least one threshold to at least one contextual criterion. Also, the method involves authenticating the claimant, if the contextual information from the claimant meets at least one of the thresholds to at least one contextual criterion. Further, the method involves allowing the claimant access to the data, if the claimant is authenticated.

摘要： A global navigation satellite system receiver manufacturer provides functional extensibility to a global navigation satellite system receiver. An application programming interface to the receiver is provided. The interface is public, such as using pubically available software or pubically distributed instructions, for loading on applications or other extensions to the core functionality of the GPS receiver. Other programmers than the manufacturer may add applications to the GPS receiver, avoiding separate devices in a vehicle.

摘要： A Low Earth Orbiting (LEO) satellite is used for broadcasting differential navigation corrections. Using LEO satellites, the “footprint” of the beam is much smaller than for geosynchronous satellites, and therefore data link bandwidth requirements are reduced to sufficiently cover an entire area. With a LEO satellite transmitting in multiple beams, these footprints become even smaller. Corrections targeted to such a small area could have the form of local area corrections (for example, raw measurements taken from a navigation reference station) using the LEO satellites.

摘要： To reduce the number of processors and/or displays in mobile equipment, an operating system is emulated in one example. A primary operating system runs on a processor or uses a particular display. The emulated operating system shares the same processor and/or same display. The emulation allows use of applications drafted or written for different operating systems in a common or shared environment. As another example, a virtual terminal function is emulated on a particular device. The particular device interacts with additional sources of information for displaying images on a same display. Using emulated operating systems or virtual terminals, a navigation program is used in a vehicle. An additional program is run on the same processor or shares the same display in the same vehicle at substantially the same time.

摘要： Wide area corrections are used substantially continuously. Local area corrections are used once or sparsely. For example, an initial position is determined with local area corrections. Wide area corrections are subsequently used. The initial position information is used in the wide area position determination to limit or avoid delay for convergence. Other sparse uses of local area corrections include verifying or updating positions based on substantially continuous use of wide area corrections.
