A mobile tracking and positioning system includes a plurality of mobile transmit and receive stations that track a mobile target which emits a radio signal in response to the occurrence of a tracking effort initiation event. The tracking stations have a GPS receiver or like means for determining their position, a radio direction finder responsive to the radio signal that determines the vector to the mobile target, a two-way communications system and a computer. The mobile transmit and receive stations exchange their position and direction to target information via the two-way communications systems, enabling the stations to triangulate the location of the target with their computers.

The present invention provides a method, apparatus, and computer program product for obtaining the location of, for example, a mobile device. An image of a target in a defined space is obtained, the target encoding data from which its location in the defined space may be determined. The position of a reference point in the image which represents the location of, for example, a mobile device, is determined relative to the target. The location of the mobile device in the defined paces is then determined by combining the location of the target in the defined space with an appropriately scaled version of the relative position of the reference point to the target in the image.

The upper part of the second frame may hold a second linear bearing assembly, with the third frame being interconnected to the second frame via the second linear bearing assembly, and with the second linear bearing assembly providing a direction of linear slide movement and an axis of rotation for the third frame, thereby providing an axis of rotation for the second axis in a plane perpendicular to the direction of linear slide movement provided by the second linear bearing assembly.

The invention discloses a multi-nodal accurate positioning and tracking method of a wireless sensor network. Positioning fixed nodes in the wireless sensor network are distributed at the peak of a regular quadrangle; each node in the sensor network is used for data acquisition and transmission; the positioning fixed nodes not only are related to a data route, but also are used for receiving positioning signals transmitted by a positioned node or a tracked node; and the positioning fixed nodes are used for calculating the distance between each fixed node and the positioned node through carrying out energy statistic to the signals, transmitting the distance to the gateway node of the wireless sensor network, and transmitting the distance to a PC machine through the gateway node. After collecting the positioning signals of all the positioning fixed nodes, the PC machine is used for calculating the position of the positioned node or a mobile node by using the multi-nodal positioning method and tracing out the movement track of the mobile tracking node through software. The invention reduces the wireless positioning cost and improves the positioning accuracy and the traceability. The invention plays an active driving role in the accurate positioning of the wireless sensor network and the tracking technology development.

A cellular wireless communication system includes base transceiver stations and mobile stations that operate with a closed loop power control. The mobile tracking is performed based on the lock in and lock out thresholds by the base transceiver stations. A forward link power control bit is decoded from the reverse channel. An additional threshold is introduced for determining at the base transceiver station whether the decoded forward link power control bit is valid or invalid. The finger energies obtained from a finger processor formed by a RAKE receiver of the base transceiver station are compared to the additional validation threshold. The additional validation threshold is independent of the tracking thresholds and usually greater than them. The validation performance may not be affected by low signal / noise. The forward link traffic channel gain of the base transceiver station is controlled in response to the invalidity of the decoded forward power control bit. The decoding of the reverse link power control bit and the validity determination of the decoded reverse link power control bit are performed by similar methods to those of the forward link power control bit. With improved validation methods, the forward link and reverse link transmission power is more accurately controlled.

To always guarantee QoS for packet transfer and to achieve continuity of QoS guaranteed paths for upstream and downstream packet transfers between a mobile communications terminal and remote terminal, a transit router TR is used to detect any change of visitor location address reported via an existing QoS guaranteed path used for packet transfer and to newly set up a QoS guaranteed path according to the results of detection. Packets are transferred via existing QoS guaranteed paths until the transit router TR completes setup of a QoS guaranteed path. The mobile communications terminal and remote terminal are notified that the setup of the QoS guaranteed path is completed.
