    • A wireless telephone system (10) capable of servicing a roaming wireless telephone user (30) includes a satellite (22) communications system consisting of at least one orbiting satellite (22); at least one terrestrial-based gateway (12, 14, 16, 18) having access to a database (20) of users, destination codes (telephone numbers); at least one network coordinating gateway (28) within at least one satellite service area (24); a single network control center (25); and a plurality of terrestrial communications links (e.g. 101). The system (10) operates by effecting communication between a terrestrial wireless telephone end user transceiver apparatus (e.g. 501) and a terrestrial communications link (e.g. 101) via a single relay through a single satellite (22) or a succession of single relay satellites (22) wherein the relay station may be in motion relative to the end user transceiver apparatus (501) and the terrestrial communications link (101). The ground-based gateway (28) effects the ultimate decision on linking in cooperation with the network database to effect hand-off from a first orbiting satellite (22) to a second orbiting satellite (22). The single satellite (22) or preferably a constellation of satellites (22) orbiting near the earth need only translate signals from the gateways (12, 14, 16, 18) to the users (30) and from the users (30) to the gateways (12, 14, 16, 18), without satellite-based control. The gateways (12, 14, 16, 18) are capable of decoding the calls, switching, processing call requests from the end users (30), processing call requests to the end users (30), processing call set-ups, handing off of calls to other satellites (22), and updating databases (20) of users (30) based on information provided by network control (25) and requests from end users (30).

    • An antenna (70) includes a first sub-structure (72) having a major plane that is oriented at a first angle (for example, 90.degree.) with respect to an axis (normal) that is perpendicular to the surface of the earth. The antenna also includes a plurality (for example six) of second sub-structures (74) individual ones of which have a local major plane that is disposed at a second angle (for example, 45.degree.) to the major plane of the first sub-structure. Each of the plurality of sub-structures have an outwardly pointing normal from the local major plane that is oriented at a third angle (for example, 60.degree.) around the axis from an outwardly pointing normal of an adjacent one of the sub-structures. The outwardly pointing normal of each of the plurality of sub-structures is disposed so as to point away from the axis. At least one antenna element (76) is supported by the first sub-structure and by each of the plurality of second sub-structures. Antenna elements of the first sub-structure and at least some of the plurality of second sub-structures enable a spread spectrum communication between a terminal (13) and at least one low earth orbit satellite (12) over a range of elevation angles of the low earth orbit satellite.

    • 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.
