摘要： A global positioning system (GPS) and auxiliary receiver receive limited range position signals broadcasted from telemetry transmitters when in an urban canyon environment. The limited range receivers preferably are implemented as part of the lighting infrastructure of the environment. The limited range receivers derive power from light from the lighting infrastructure. The receivers can also include a transmitter for retransmitting the receive position data and an ID code to a central processing center.

摘要： A platform attitude determination can be made with a single receiver in a global positioning system (GPS). The receiver receives at least three sets of GPS signals from three antennas. Two of the GPS signals are delayed so that the receiver receives each GPS signal in separate time domain slots. In this way, the synchronization of separate GPS receivers does not have to be accomplished.

摘要： A system for monitoring guiding and controlling an unmanned, unteathered flight vehicle, generally assumed to be moving through the earth's atmosphere at a high rate of speed. The system is comprised of on-board positional receiver and processing means coupled to a transceiver capable of combining such positional information with additional data relative to the health and status of the flight vehicle and transmitting the same to a ground station of compatible and simplified design. A preferred positional determination means is to utilize a form for GPS signal thereby affording one the opportunity to include appropriate processing software or additional componentry if necessary for base station purposes and thereby provide a relatively inexpensive system having a low probability of detection for intercept that simultaneously yields vastly improved operating performance characteristics over the mere translation of received GPS signals to down-link or to remote stations as known in the prior art.

摘要： Disclosed is an avionics display device adapted for insertion into an avionics panel of an aircraft. The avionics display device includes a liquid crystal display having a liquid crystal display element and a bezel surrounding the liquid crystal display element. The avionics display device also includes a low profile rotary switch mounted on the bezel of the liquid crystal display to save avionics panel space in the aircraft. The low profile rotary switch includes a printed circuit board positioned beneath the bezel and having a plurality of electrical pads formed thereon. The switch also includes a contact member positioned adjacent the printed circuit board and having a first contact formed thereon. Rotation of the contact member causes the first contact to be electrically coupled to one of the plurality of electrical pads formed on the printed circuit board. A knob is coupled to the contact member such that rotation of the knob causes rotation of the contact member. The detent mechanism of the switch is positioned in the knob to lower the profile of the switch.

摘要： A multi-dimensional equalizer/decoder is disclosed for equalizing a channel transmitting electrical pulses corresponding to a plurality of interdependent symbols formed according to the rules of a multi-dimensional code (e.g. block lattice coded modulation). The symbols are received by the equalizer/decoder over multiple symbol (baud) periods because it takes more than one symbol period to receive a minimum decodable number of symbols on the given number of physical channels. The equalizer/decoder employs a preliminary and a final decision device which cooperate with the components of an "equalization layer." A plurality of equalization layers may be used if the symbols are received over a plurality of physical channels. Each equalization layer has first, second, and third, adaptive, feed forward filters, along with appropriately located buffers for collecting decodable groups of the transmitted symbols for group-by-group provision to the decision devices.The equalizer/decoder beneficially permits equalization of a channel used to transmit a multi-dimensional code block, for example, without requiring that a decodable number of symbols arrive in a single symbol interval. Accordingly, a communication system incorporating the equalizer/decoder may implement a high order, multidimensional code that provides enhanced coding gain even where the number of symbols in the code is so large that, given the physical channels available, it must be transmitted over multiple symbol periods. Where the code permits, the equalizer/decoder may make preliminary decisions regarding a reduced number of symbols while continuing to make final decisions using the maximum number of symbols to achieve maximum code gain.
摘要翻译：公开了一种多维均衡器/解码器，用于对与根据多维码（例如块格子编码调制）的规则形成的多个相互依赖符号相对应的电脉冲进行均衡。符号由均衡器/解码器通过多个符号（波特）周期接收，因为在给定数量的物理信道上需要多于一个符号周期来接收最小可解码数量的符号。均衡器/解码器采用与“均衡层”的组件协作的初步和最终决策设备。如果在多个物理信道上接收符号，则可以使用多个均衡层。每个均衡层具有第一，第二和第三自适应前馈滤波器，以及适当地定位的缓冲器，用于收集所发送符号的可解码组，用于逐组提供给决策设备。均衡器/解码器有利地允许用于发送多维码块的信道的均衡，例如，不要求可解码数量的符号以单个符号间隔到达。因此，结合均衡器/解码器的通信系统可以实现高阶多维码，其提供增强的编码增益，即使代码中的符号数量如此大，使得在给定可用的物理信道的情况下，它必须通过多个符号时期。在代码允许的情况下，均衡器/解码器可以对减少数量的符号进行初步判定，同时使用最大数量的符号来继续作出最终决定以实现最大代码增益。
