The system and method to allow a cellular enabled device that lacks two-way satellite communication to receive incoming calls over a satellite network where the mobile terminating call is initially addressed to the cellular mobile phone number. In one embodiment, the system and method allows the cellular device to appear as a device roaming on a satellite network or sub-network. In another embodiment, the system places a call forward request to a satellite enabled device, where the call forward request is transparent to the user.

Cell tower functionality with satellite access to allow a cell device to roam on a satellite network or call forward on a satellite network

An improved satellite communication system is provided comprising at least one satellite wherein each satellite provides multiple beams, a plurality of UTs, and at least one gateway connected to a PSTN and communicating with said at least one UT or with a constellation, wherein each of the UTs within a given frequency band is distinguished from another of the UTs employing a combination of TDM and NOPN codes and time slots.

Satellite communication system employing a combination of time division multiplexing and non-orthogonal pseudorandom noise codes and time slots

A communications system comprising a first transceiver and a second transceiver, which system employs a device that measures power over a frequency band from sources other than those monitoring downlink radiation received at a radio terminal from the satellite, and a controller that receives these power measurements to determine on which frequency channel within a band a transmitter is to transmit.

Method for frequency channel selection in a satellite communication system

A satellite communication system for communicating between a plurality of user terminals is disclosed having at least one satellite which provides multiple beams, a plurality of user terminals that communicate with each other via satellites of said constellation, at least one gateway connected to a public switched telephone network and communicating with at least one user terminal over the satellite communication system wherein each of said user terminals within a given frequency band is distinguished from another of the user terminals employing a combination of time slots and orthogonal codes implemented in a forward and return link. Each of the user terminals is equipped to initiate or receive or terminate packet data messages. Each of said user terminals is handed off from one beam of a satellite to another beam of said satellite. The hand off is predicated on signal strength determined at said plurality of user terminals.

Satellite communication system employing a combination of time slots and orthogonal codes

A system or method is disclosed which employs filters on a satellite whose bandwidth is varied by ground command to restrict interference experienced by a satellite as an auxiliary terrestrial component (ATC) system is increased to a multiplicity of cities and markets. Thus there is provided a novel method and system which optimizes overall MSS and ATC traffic.

System and method for providing an improved terrestrial subsystem for use in mobile satellite systems

A communications system including a SN Device including a satellite transmitter and a local wireless transceiver and a GUI Device, separate from the SN Device. The GUI Device includes a user interface and local wireless transceiver capable of establishing a wireless link with the SN Device. The GUI Device transmits command information to the SN Device and the SN Device transmits at least location data to a satellite network.

Method and apparatus for transmitting message from short-range wireless device over a satellite network

An asset locator device including (a) a wireless receiver capable of receiving an identifier signal transmitted from a short range wireless transmitter device; (b) a wireless transmitter capable of transmitting a message to a space based network; (c) a positioning system capable of determining the location of the locator device; (d) a vibration sensor; and (e) a controller. The controller instructs the asset locator to: (i) attempt to detect the identifier signal from the transmitter device if the vibration sensor senses vibration; and (ii) transmit a signal, including an asset location, to the space based network if: (1) the identifier signal is not detected; and (2) location fixes from the positioning system indicate a location change of the asset.

Simplex personal and asset tracker

There is provided a method for improving an allocation of resources, i.e., frequency and power, to terrestrial services and satellite services that use a same frequency band. The method includes determining a demand (D) for a resource by users of a satellite system, determining a demand (D) for the resource by users of a terrestrial system, and allocating the resource between the satellite system and the terrestrial system based on a ratio of Dto D.

Resource allocation to terrestrial and satellite services

Handover between ATC and satellite component of an integrated MSS/ATC system

Disclosed are systems, apparatus and methods for tracking or locating an asset along with providing emergency and non-emergency messaging services. An asset tracker is disposed on an asset. The asset tracker has a motion sensor, a GPS receiver and a simplex satellite transmitter for communicating with a remote location (back office processing center). The asset tracker also has a short-range transceiver for communicating with a fob device carried by a user. If an authorized fob device is not in range of the asset tracker device and the asset tracker device moves, as determined by the motion sensor and/or GPS location data, GPS data are transmitted via a satellite to the back office. The office sends the information to a desired recipient (asset owner, law enforcement, etc.). The fob device communicates with the asset tracker device when it is in proximity thereof. The fob device is programmed to have depressible buttons that transmit emergency and non-emergency messages to the asset tracker device which communicates the GPS location and message via a satellite to the back office. The back office sends the information to a desired recipient. Messages processed at the processing center are sent as email messages to one or more designated email addresses, as a short message service (SMS) messages to one or more designated cell phones, or as messages to an asset recovery service or 911 emergency center.
