Abstract: A satellite tracking system and method, a three-point peaking technique is used to determine the direction of a satellite 50 which includes a signal source. A Kalman filter is used to minimize the effects of noise in the received signal during the three-point peaking operation. This determination may be made at any time. Once the position of a satellite 50 has been determined twice over a time interval, its future position may be estimated by an adaptive continuous step track technique, using a Kalman filter, which assumes that the satellite moves uniformly with time as viewed from the antenna.

Abstract: A method of operating a cellular base station subsystem such as a smart bias tee. The method comprising: modulating a first control data signal to generate a first modulated carrier signal; multiplexing said first modulated carrier signal with a first RF antenna signal onto a feed line; demultiplexing a second RF antenna signal and a second modulated carrier signal from said feed line; demodulating the second modulated carrier signal to generate a second control data signal; analyzing at least one of said signals to generate diagnostic data; and outputting said diagnostic data. The subsystem also has an addressable memory adapted to provide data on request from said subsystem.

Abstract: A cellular telecommunications system and methods of monitoring, control and communication within such a system. In one aspect redundancy is provided by a second mode of communication for control signals should the primary mode be unavailable. In one embodiment a secondary wireless network is provided in case of failure of a backhaul link. This allows the control of ancillary equipment in case of unavailability of the primary mode of communication. In another aspect continuity of telephony signals may be provided in a cellular communications system by utilising one or more wireless link between base stations to convey telephony signals normally conveyed via a backhaul link.

Abstract: A launch monitor that includes substantially all of its functional components on or within a housing is disclosed. In one embodiment, the launch monitor is capable of being transported and used in any desired location. One or more camera's, flashes, and triggers may be used to acquire images of a golf club and golf ball. The launch monitor is preferably capable of receiving and transmitting data over a wireless network. Acquired images and other data may be analyzed by a processor, and then displayed using an LED, LCD or other type of display or printer. The launch monitor may “recognize” a plurality of golf clubs and golf balls based on an optical fingerprint. The optical fingerprints, which are preferably stored in a memory, allow the launch monitor to identify a golf club and/or ball substantially soon after they are placed in the field of view of the monitor Optical fingerprinting enables automatic record keeping, and storing performance data and equipment used simultaneously.
