Five ground stations including a master and four slaves communicate with each other and all aircraft in the ATC areas. The same precise 3D position of all aircraft operating in that ATC airspace is simultaneously computed by all the aircraft in that ATC area utilizing the measured distance between the aircraft and ground stations in that area providing full automated support for landing, take-off and taxi operation of the aircraft to a Gate or from a Gate, by using a ground infrastructure of radio communication stations which are operating worldwide within a 16 MHZ frequency spectrum from the existing DME 962-1213 MHZ spectrum. During functioning of the system, any mobile equipped with a dedicated receiver could determine its 2D position on the ground within an airport area or within any ATC area, such mobile being a truck, a car, a boat, a train, a mobile phone, or any other mobile operating in that ATC. Other implementation of this system is a RUNWAY system where one such system will cover the operation of aircraft on both side of Runway and could entirely replace existing ILS or MLS at a fraction cost. Similar operation could be achieved by using audio or ultrasonic signals for a precised 2D/3D position location for other applications.","PeriodicalId":102388,"journal":{"name":"PLANS 2004.

GPS signals are among these \"restricted\" bands. Several groups in the GPS community have conducted experimental studies concerning the impact of UWB interference on the performance of various grades of commercial and aviation GPS receivers. In this paper, we present a software approach to simulate and evaluate UWB interference on GPS receivers. The software approach provides greater flexibility in the design of testing scenarios, such as the inclusion of a large number of aggregated UWB devices, the generation of new UWB signals and modulation schemes, and the possibility of extending the study to new GPS signals. The paper will discuss a general framework for developing algorithms to evaluate UWB and GPS interference under a wide variety of hardware and software conditions. This framework consists of three classes of components: Input, Processing, and Analysis. The input components are responsible for the generation of current UWB signal waveforms, UWB signal modulation schemes, and various forms of GPS signals. The processing components include a simulated model of GPS RF front end and software implementation of GPS processing blocks, such as acquisition, tracking, and post-processing. The Analysis components focus on the study of specific receiver processing component outputs. Both real and simulated UWB signals can be used in the study. The real UWB signals are primarily used to validate the simulation procedure, whereas the simulated UWB signals are used to allow the immediate incorporation of new UWB waveforms and modulations in the evaluations. The paper will present details of the software components developed and the preliminary results obtained to date.","PeriodicalId":102388,"journal":{"name":"PLANS 2004.

To assist the gyro development and manufacturing an automated test system was created. The system is low cost one with modular and flexible structure controlled by computer having both basic and advanced features. The first aim was to create flexible system to meet test requirements of different development stages of a gyro and then manufacturing. The further major objectives of the work were accurate measurement of gyro characteristics, comprehensive characterization and performance evaluation, reducing of gyro development cycle time by the test system using suitable hardware and software combination. Methodology of the system is building an automated, modular, scalable, flexible system using of available standalone equipment with PC remote operation capabilities. The test system is hierarchically controlled by host computer with General Purpose Interface Bus (GPIB) interface and special software, and may consist of various required and optional equipment. The software written in Visual Basic has both data acquisition and analysis capabilities providing: a flexible utilization each unit of the equipment, redistribution of computational power between host computer and standalone instruments, data saving in a detailed form for quick and convenient postprocessing and plotting. The software structure is built using a concept of object oriented programming. Latest software allows to carry out calibration and 7 different tests including a frequency response, phase delay, output signal level, signal-to-noise ratio, power spectral density of noise, time domain noise level, and many calculated parameters, such as scale factor, linearity error and others. The test procedure follows as much as possible recommended guidelines of IEEE standards for gyroscope testing. In this paper, principles of the test system, application, results and future demands are discussed.","PeriodicalId":102388,"journal":{"name":"PLANS 2004.

There are some unique differences in the land applications over the air and marine applications, such as occasional larger turn in yaw angle and only a small fluctuation in the other two axes of orientation. Under these conditions a simplified system for some land applications with a single gyroscope aligned vertical to measure yaw rate and an accelerometer or a vehicle odometer for vehicle forward linear motion may suffice and small fluctuation on roll and pitch values and corresponding accelerations ignored. This configuration reduces system cost and simpler processing. To understand what accuracy can be obtained using such a system, this paper first presents simple formulas used in 3D and 2D sensor configuration. The formulas are then used to evaluate errors in position from ignoring the small quantities. The magnitude of errors can help to make a decision for a choice of a 2D or 3D system to meet the accuracy sought. Experiment to get difference in position from actual results using 3D system results with the data from the same system derived in 2D mode is also important and it is under evaluation.","PeriodicalId":102388,"journal":{"name":"PLANS 2004.
