摘要： An integrated communications, navigation and surveillance system includes a plurality of satellites in communication with one another and broadcasting navigation signals. The satellites are capable of bi-directional communication and of receiving and relaying surveillance signals. A user segment includes at least one mobile user device operable to communicate with the satellites and to broadcast a surveillance signal to the satellites. The user device is also operable to compute its position based upon received navigation signals. The system uses the surveillance signal broadcast by the user device to monitor a position of the user device. The position of the user device determined by the system and by the user device can be shared to provide backup surveillance and backup navigation capabilities.

摘要： A cellular telephone system has call management decisions made based on the exact geographic location of the mobile unit. These call management decisions include billing and taxing decisions, cell site selection, frequency selection and even cellular system selection. The decisions are continuously updated during a call whereby decisions can be made and changed regardless of where a call originated. Cell site location, and even cellular system selection, can be made in a specific manner to best serve the needs of the mobile user, the cellular system as well as the public. It is even possible for a cellular system to locate one or more of its cell sites in the geographic area served by another cellular system. In some cases, cellular systems might even share cell sites.

摘要： Disclosed herein is a system for rapidly resolving position with centimeter-level accuracy for a mobile or stationary receiver [4]. This is achieved by estimating a set of parameters that are related to the integer cycle ambiguities which arise in tracking the carrier phase of satellite downlinks [5,6]. In the preferred embodiment, the technique involves a navigation receiver [4] simultaneously tracking transmissions [6] from Low Earth Orbit Satellites (LEOS) [2] together with transmissions [5] from GPS navigation satellites [1]. The rapid change in the line-of-sight vectors from the receiver [4] to the LEO signal sources [2], due to the orbital motion of the LEOS, enables the resolution with integrity of the integer cycle ambiguities of the GPS signals [5] as well as parameters related to the integer cycle ambiguity on the LEOS signals [6]. These parameters, once identified, enable real-time centimeter-level positioning of the receiver [4]. In order to achieve high-precision position estimates without the use of specialized electronics such as atomic clocks, the technique accounts for instabilities in the crystal oscillators driving the satellite transmitters, as well as those in the reference [3] and user [4] receivers. In addition, the algorithm accommodates as well as to LEOS that receive signals from ground-based transmitters, then re-transmit frequency-converted signals to the ground.

摘要： A wireless terminal and auxiliary system are disclosed that enable the wireless terminal to determine its location based on signals transmitted from navigation satellites. In particular, the tasks of signal acquisition and signal processing required of a wireless terminal in the prior art are divided between the wireless terminal and the auxiliary system in accordance with the illustrative embodiment. The auxiliary system assists the wireless terminal by acquiring information about the satellites' ephemerides, by partially processing it and by transmitting the partially processed information to the wireless terminal in a form that is useful to the wireless terminal. The wireless terminal then uses the partially processed information from the auxiliary system to assist the wireless terminal in acquiring the ranging signals from the navigation satellites quickly and when they are weak.

摘要： A method for determining the geolocation of an object such as a vehicle traversing the earth's surface or airborne thereabove includes employing a device which is capable of operating autonomously to transmit signals to a selected low earth orbit (LEO) satellite for relay to a receiving station whose position is known, identifying the device and its geolocation, speed, altitude and/or heading. The device includes a microcomputer which operates a Global Positioning System (GPS) receiver for receiving GPS signals to identify the device geolocation and the precise time. A nonvolatile memory on board the device stores LEO satellite ephemeris data, satellite operational and message formatting parameters, LEO satellite visibility footprint data and visibility contour information for the device caused by obstacles which are permanently or temporarily in proximity to the device during deployment and which block transmission of signals between the device and the LEO satellite, depending on relative positions. Geolocation information is transmitted to a LEO satellite for relay to the receiving station after calculation of covisibility of the satellite with the receiving station and the transmitter antenna for the device, taking into account the device visibility contour and heading. The device transmitter antenna may have a steering mechanism for causing the antenna to be aimed at a predetermined azimuth and elevation wherein the transmitted signals will be intercepted by the LEO satellite.

摘要： A method for assigning a system location to an ISU (32) residing in a wireless communication system coverage area (20) that has a plurality of billing territories (40). Base points (42) are defined to be proximate the billing territories (40) such that each of the base points (42) provides a system location for a corresponding billing territory (40). Each of the billing territories (40) has a plurality of reference points (44) distributed therein in accordance with a geographic independent algorithm such that each of the reference points (44) is described by an offset from the corresponding base point (42) of the corresponding billing territory (40).

摘要： A cellular telephone system includes a plurality of cell sites and a mobile telephone switching office. Call management, including selection of a cell site most appropriate for a call associated with a mobile unit, are made based on the geographic location of the mobile unit as opposed to the strength of the signal associated with the call. The geographic location of the mobile unit is precisely determined using a NAVSTAR global positioning system, or its equivalent. Each mobile unit includes a GPS receiver that receives information from a geostationary satellite to determine the precise location of the mobile unit. This position information is relayed to the cell site initially managing the mobile unit, and the mobile unit is handed off to a cell site that is most appropriate for the call. Initial selection of an entrance cell site is made based on signal strength, but further call management decisions are made based on location of the mobile unit.
