Systems and methods which provide mapping an arbitrary outdoor environment and positioning a ground-based vehicle relative to this map. In one embodiment, a land-based vehicle travels across a section of terrain, recording both location data from sensors such as GPS as well as scene data from sensors such as laser scanners or cameras. These data are then used to create a high-resolution map of the terrain, which may have well-defined structure (such as a road) or which may be unstructured (such as a section of desert), and which does not rely on the presence of any “landmark” features. In another embodiment, the vehicle localizes itself relative to this map in a subsequent drive over the same section of terrain, using a computer algorithm that incorporates incoming sensor data from the vehicle by attempting to maximize the likelihood of the observed data given the map.

The present invention is a method and system for transferring calls among communicating devices connected through a public network. The service is offered by a public network to permit a party in a ongoing conversation to transfer a call to another communicating device that may be more convenient to use, such as from a mobile telephone experiencing static to a land-based telephone, or from a home telephone to a mobile phone as a party leaves the home. In a method according to the invention, the network first establishes a connection between two communicating parties. The network then receives from one of the parties a request to transfer the call to another communications device. The network then transfers the call. The invention may be entirely network-based, in which case there may be a database of transferee devices stored on the network. Alternatively, the invention may be hybrid network-based and premises equipment-based, in which case the database of transferee devices may be stored in the premises equipment.

A modular device, system and associated method, used to enhance the quality and output speed of any generic GPS engine is provided. The modular device comprises an inertial subsystem based on a solid state gyroscope having a plurality of accelerometers and a plurality of angular rate sensors designed to measure linear acceleration and rotation rates around a plurality of axes. The modular inertial device may be placed in the data stream between a standard GPS receiver and a guidance device to enhance the accuracy and increase the frequency of positional solutions. Thus, the modular inertial device accepts standard GPS NMEA input messages from the source GPS receiver, corrects and enhances the GPS data using computed internal roll and pitch information, and produces an improved, more accurate, NMEA format GPS output at preferably 2 times the positional solution rate using GPS alone. The positional solution frequency using the present invention may increase to as much as 5 times that obtained using GPS alone. Moreover, the modular inertial device may assist when the GPS signal is lost for various reasons. If used without GPS, the modular inertial device may be used to define, and adjust, a vehicle's orientation on a relative basis. The modular inertial device and architecturally partitioned system incorporated into an existing GPS system may be applied to navigation generally, including high-precision land-based vehicle positioning, aerial photography, crop dusting, and sonar depth mapping to name a few applications.

A satellite communications system uses multiple ground stations and one or more satellites for communicating between mobile subscribers and a land-based communications network, such as the PSTN or the Internet. Multiple ground stations geographically dispersed minimize toll charges incurred routing calls from a mobile subscriber through the land network by reducing the need for long-distance calling. Further, because each ground station communicates with a given satellite using the same frequency spectrum, the subscriber capacity of the system increases and/or bandwidth requirements for the communications link between ground stations and satellites may be reduced. The present system uses ground-based beamforming techniques enabling each satellite to transmit signals in multiple transmission beams, each beam supporting one or more mobile subscribers. Each beam may reuse the same frequency spectrum, thereby increasing the number of subscribers supported by each satellite. Multiple ground stations cooperatively relay signals through a given satellite in a manner complementary with ground-based beamforming.

A system and method for controlling vehicular traffic flow is disclosed, which creates a communication system between vehicles that allows the vehicles to share their respective velocities and acceleration or deceleration rates. Thus, each vehicle within the system can respond immediately to any acceleration or deceleration rate changes of the surrounding vehicles (e.g., the vehicle directly in front, directly in back, and in the adjacent lane). Essentially, the system functions similar to a wireless vehicular train, with a queue of cars linked together by a stiff, wireless communications “chain”. Notably, the term “vehicle” is not limited only to land-based vehicles (e.g., motor vehicles), and the system can include airborne vehicles (e.g., multiple aircraft flying in close formation, military aircraft flying in drone formation, etc.). For example, a system for controlling vehicular traffic flow is disclosed, which includes in each vehicle of a plurality of vehicles, a wireless or infrared (IR) modem for inter-vehicular communications, a range finder for determining the distance and closing rate between vehicles, a processing unit for retrieving vehicular operational data (e.g., velocity, angular velocity, acceleration rate, deceleration rate, braking pressure, weight, pointing vector, etc.) and executing flow control system software instructions, and a vehicular flow control communications protocol that enables the communication of various flow control parameters between vehicles via the wireless or IR modem. Thus, each vehicle in the system “knows” what the surrounding vehicles are doing and can respond immediately to changes in the traffic flow. As such, the system minimizes the distribution of vehicles' velocities in the queue, and increases traffic throughput and safety as a result.

The process can be either land based or sea based.

A seismic exploration method and unit comprised of continuous recording, self-contained wireless seismometer units or pods. The self-contained unit may include a tilt meter, a compass and a mechanically gimbaled clock platform.

The unit may correct seismic data for the effects of crystal aging arising from the clock. Deployment location of the unit may be determined tracking linear and angular acceleration from an initial position. The unit may utilize multiple geophones angularly oriented to one another in order to redundantly measure seismic activity in a particular plane.

An Interactive Mobile Aquatic Probing and Surveillance system. The system includes a remote aquatic or amphibious agent which is controlled by a typically land-based computer host. The agent is a field robot in the form of a comparatively small and inexpensive, untethered, self-propelled, aquatic or amphibious, non-submersible vehicle that preferably carries physical and water characteristic sensors, as well as other operational equipment for use on relatively small bodies of water and wetlands. The host interacts with a human operator and provides control commands to and receives data from the agent in real time via a wireless communication between the agent and the host. The control commands include guidance commands including navigational and propulsion commands as well as commands for operating the sensors and various other equipment carried by the agent.

A system and method for carrying out a hand-off of a satellite-based communications link with a mobile platform, such as an aircraft, leaving a first coverage region and entering a second coverage region. A land-based communications link connects ground stations in each of the coverage regions for communications with one another and also with a network operations center (NOC). As the aircraft enters an area of overlap between the two coverage regions, a sequence of communications is initiated between the ground stations and also between each of the ground stations and the aircraft to ensure that new forward link and return link assignments are received by the aircraft before the aircraft relinquishes its communications link with the first ground station to begin communicating with the second ground station. The hand-off in communications is accomplished in less than approximately 30 seconds of time after one of the ground stations detects that the aircraft has entered a pre-defined overlap area between the two coverage regions.
