This standard or sensors, receivers, algorithms and their implementation can be used for a wide range of systems such as ships, airplanes and missiles. However, gun-launched munitions have special requirements due to the following restrictions: initialization and transfer alignment is impossible before launch; launch shock changes sensors which results in significant unknown errors; roll rates can exceed the range of gyros. The resulting system requirements can be met by special sensor concepts such as additional magnetometer sensors and special navigation algorithms. This paper presents an alternative sensor concept and navigation algorithm for gun-launched munitions. Navigation systems of gun-launched shells have to comprise g-hardened sensors and need to be initialized some time after launch. Using special algorithms based on Kalman Filters a sufficient and fast attitude initialization is possible. Additional stabilization of attitude can be achieved by incorporating magnetometer sensors in the navigation solution. The sensor concepts and algorithms are explained and results achieved in simulation, Hardware in the Loop and flight tests are presented.","PeriodicalId":102388,"journal":{"name":"PLANS 2004.

SSBNs must maintain high-accuracy navigation over long periods in blue water without exposure. SSNs, SSGNs and UUVs must be able to operate covertly in littoral waters for extended durations. In the future, submarines must be capable of conducting these missions with increased performance both with and without GPS. These future submarine navigation capabilities are necessary for the Navy to achieve its goals for Precision Engagement and Full Dimensional Protection using Network Centric Warfare concepts. Network Centric Warfare emphasizes systems rather than platforms, and uses advanced communications to network individual platforms to provide significant improvement to their collective performance. In order to share intelligence effectively across platforms, each platform must maintain an accurate knowledge of its position. Common to all of the U.S. Navy's current requirements and future plans is the need for submarine navigators to covertly maintain accurate outputs with reduced dependence on GPS. With this view toward current and future submarine navigation requirements, Lockheed Martin Maritime Systems and Sensors (MS2) Mitchel Field has been developing geophysical navigation technologies to enhance submarine navigation performance and reduce dependence on GPS. Most recently MS2 has successfully demonstrated a next generation bathymetric fix technology that maintains performance while eliminating the operational restrictions inherent in the current technology. MS2 has also successfully demonstrated our unique gravity navigation technology based on gravimeters and gradiometers aboard SSN691 Memphis. This paper discusses MS2's bathymetric and gravity technologies as well as velocity sonar techniques and cost effective approaches for implementing these capabilities on SSN and potentially UUV platforms.","PeriodicalId":102388,"journal":{"name":"PLANS 2004.

In this case, the measurement bias aggravates the estimation ability of a filter for inertial navigation system and corrupts the estimate of the filter. If the magnitude of the bias is large, fault detection and isolation techniques are often used for rejection or suppression of the effect of the bias. However, if the magnitude of the bias is small, the fault detection and isolation techniques cannot reject or suppress the effect of the bias. In this paper, the INS vertical channel using a barometer and GPS is considered. The GPS measurement is supposed to have bias noise. The magnitude of the bias is supposed to be small, therefore the FDI techniques cannot reject or suppress. For this case, a method of estimating and compensating the measurement bias in GPS output is proposed. In this scheme, the residuals of GPS output with measurement bias are stored for appropriate duration and, with these residuals, linear equations of measurement bias is developed. Then, simple least square method can estimate the bias, and, with this estimated value, GPS output can be compensated and a portion of the bias can be removed. In simulation results, it is shown that the scheme has an effect of measurement bias suppression.","PeriodicalId":102388,"journal":{"name":"PLANS 2004.

At present, Japanese Quasi-Zenith Satellite System (QZSS) is planned under government-private sector cooperation. QZSS is considered as a multi-mission satellite system, it is able to provide communication, broadcasting and positioning services for mobile users in specified region with high elevation angle. The performance of a Global Navigation Satellite System (GNSS) can be quantified by availability, accuracy, reliability and integrity. The additional GPS compatible signal from QZSS can remarkably improve the availability, accuracy, reliability and integrity of GPS positioning. This paper focuses on the performance of GPS augmentation using QZSS in Japan and its neighboring areas. The constellation and signal structure of QZSS are briefly introduced. The measures for performance evaluation are described. The availability, accuracy, reliability and capability of carrier phase based positioning of GPS augmentation using QZSS are obtained by software simulation. The simulation results are presented using the number of visible satellites as a measurement of availability, Geometrical Dilution of Precision as a measure of accuracy and minimal detectable bias as a measure of reliability and ambiguity success rate as a measure of capability of carrier phase based positioning, with spatial and temporal variation. It is shown, that QZSS will not only improve the availability and accuracy of GPS, but also enhance the system reliability and the capability of carrier phase based positioning in Japan and its neighboring areas.","PeriodicalId":102388,"journal":{"name":"PLANS 2004.

By utilizing bidirectional GPS transceivers (incorporating separate GPS pseudolites and GPS receivers) deployed in a ground-based array, the SCPA can provide all the benefits of satellite-based Carrier-phase Differential GPS (CDGPS), such as drift-free, centimeter-level, and three-dimensional positioning, without requiring a satellite constellation on Mars. Relative geometry change by moving the rover enables the SCPA to self-calibrate both the array locations and the rover trajectory to centimeter-level accuracy. This self-calibration capability of the SCPA overcomes the difficulty of autonomous robotic deployment of the pseudolite-based navigation system on Mars, eliminating the need for accurate a priori position information or precise placement of the array. This paper presents new results from the latest field trial of the SCPA conducted in February 2004 using the K9 Mars rover platform operated in the Marscape at NASA Ames Research Center. This field trial demonstrates the entire scenario of the SCPA operation, starting with autonomous array deployment, followed by array self-calibration and centimeter-level navigation for a long traverse. The results show that a 0.2% drift rate is achieved by the SCPA navigation (0.4 meter of the final positioning error after a 174.7 meter traverse).","PeriodicalId":102388,"journal":{"name":"PLANS 2004.

Probably the first requirement is for an advanced global communications, navigation and surveillance (CNS) system. The present plan with augmented GPS will be quite inadequate, being short in functions, economy and especially security, with upcoming air traffic increases. A system concept called the Integrated Global Surveillance and Guidance System, when implemented, will meet these requirements for a number of decades to come. However, an advanced CNS system for ATC/ATM is only the first step. Many new procedures will be required to handle the substantially increased air traffic expected. The more precise guidance and surveillance provided by IGSAGS will permit increased traffic density both horizontally and vertically. While the enroute structure can be built to handle substantial traffic increases, the terminal area is another story. The 3 to 5 miles required spacing between jets on the final approach because of vortex turbulence is a serious limiting factor for airport traffic. The National Research Council (NRC) has brought out the need for major improvements in aircraft, including vertical takeoff and landing aircraft. This would eliminate the need for long runways and allow changes in airports that would permit substantial increases in traffic. What will we have by the end of the century possibly \"flying cars\" that won't have wings, propellers, jets or even hydrogen as fuel.","PeriodicalId":102388,"journal":{"name":"PLANS 2004.

Because of substantial path loss, the received signal power from satellites is extremely weak and even below the thermal noise floor and as such is very sensitive to changes in the underlying noise floor. The goal of this work is to investigate the radio spectrum environment in the GPS band along with two additional bands, the Unified-S band and 2.4 GHz Industrial Scientific and Medical (ISM) band. The spectrum survey was conducted at various locations in the San Francisco Bay area including various urban, rural areas and airports and harbors which are operational significant to GPS. The measurement data collected in this study will provide a more accurate representation of the current status and the characteristics of the spectrum environment. Geographical variation within the sites will reveal correlation between the spectrum environment and the level of urbanization and also a comparative study on the frequency bands under different level of regulations can be used to investigate the effectiveness of the current spectrum policy.","PeriodicalId":102388,"journal":{"name":"PLANS 2004.
