However, achieving the required accuracy and availability is still a challenge. Multisensor navigation is one of the techniques that has shown promising results in addressing the challenges of such areas. Being able to incorporate raw low-level sensor data is advantageous as it allows to incorporate all available information and more accurate estimation models. In this paper a Particle Filter based multisensor positioning system is extended to use pseudorange measurements of a GPS sensor instead of a calculated position solution. Using pseudoranges, any number of visible satellites can improve positioning accuracy, when combined with measurements from other sensors like an electronic compass, a barometric altimeter or a foot mounted inertial measurement unit (IMU). Additionally, statistical error models for pseudoranges are integrated and tested. Our results show that by using the models within the Bayesian framework yields promising results in terms of error mitigation.","PeriodicalId":94036,"journal":{"name":"IEEE/ION Position Location and Navigation Symposium : [proceedings].

An alternative erection procedure for on-ground transfer alignment 另一种地面转移校准的安装程序

{"title":"An alternative erection procedure for on-ground transfer alignment","authors":"H. Rotstein, Y. Baumgarten","doi":"10.1109/PLANS.2010.5507178","DOIUrl":"https://doi.org/10.1109/PLANS.2010.5507178","url":null,"abstract":"This paper presents a procedure for computing the relative orientation between two static inertial navigation systems: a primary and a secondary. The primary system is assumed to be of navigation quality and therefore capable of gyro-compassing to the desired accuracy. The secondary is lower quality and requires external aiding for azimuth and accurate leveling initialization. The assumption that allows the transfer alignment is that the primary and the secondary are rigidly mounted on a mechanical structure that allows for joint rotation around one or more axis while maintaining the relative orientation between the two systems. A pitch axis is typical in practical systems and hence the name “Erection Procedure.” As opposed to the Kalman-filter based procedures in use in several systems today, the new method does not require the computation of a navigation solution while the mechanical system is been erected. Instead, measurements from the navigation sensors are required at a number of discrete stages, and then these measurements are processed to compute the relative orientation between the primary and the secondary. The procedure is easy to implement and yields an exact solution to the problem whenever the underlying assumptions are exactly met. It has been shown to work well both in simulations and in practice. In addition to its practical relevance, this work also sheds additional light into the general question of aligning two static navigation systems.","PeriodicalId":94036,"journal":{"name":"IEEE/ION Position Location and Navigation Symposium : [proceedings].

GPS signals may suffer from blockage in urban canyons and tunnels resulting in interrupted positioning information. Inertial sensors are standalone sensors that can be integrated with GPS and can bridge the blockage periods as they do not rely on any external signals. Recently, miniaturized Micro-Electro-Mechanical Systems (MEMS)-based inertial sensors are abundantly used for vehicle safety applications such as air-bag deployment, roll-over detection, etc. These sensors can be used as inertial navigation system (INS) after integrating with GPS for reliable navigation solution even in denied GPS signal environments. The traditional technique for this integration is based on Kalman filter (KF) with a dedicated inertial sensor module consisting of three orthogonal gyros and three orthogonal accelerometers. This research targets a low cost navigation solution for land vehicles and hence it utilizes a reduced inertial sensor system (RISS) consisting of MEMS-based single axis gyro and a dual axis accelerometer. Additionally, the vehicle's odometer is used and an integrated 3D navigation solution is achieved. To improve the positioning accuracy a nonlinear filtering technique, particle filter (PF) is used to avoid linearization errors. Because of PF ability to deal directly with nonlinear models, it can accommodate arbitrary sensor characteristics and motion dynamics. Consequently, tightly coupled integration which has a nonlinear measurement model can be directly used in PF without introducing any errors. An enhanced version of PF is implemented known as Mixture PF and the performance of this method is examined by actual road tests in a land vehicle and compared with KF.","PeriodicalId":94036,"journal":{"name":"IEEE/ION Position Location and Navigation Symposium : [proceedings].

It is a new Sagnac effect that an interferometer “loop”, formed by placing double weak links in a toroid filled with superfluid He4, can detect the interference of superfluid matter waves generated by the AC Josephson oscillation in weak links. In this paper, the potential advantages of superfluid gyroscope were estimated. The most important advantage is the very high sensitivity which could be increased theoretically by a factor of 1010 than the sensitivity of traditional Ring Laser Gyroscope. But such a superfluid gyroscope still faces some difficulties when it is used as an angular velocity measuring device for navigation, the most important one is the conflict between the high sensitivity and wide measurement range. Then, two methods were discussed to solve that conflict which is a key problem in current superfluid gyroscope research. The first method is “flux-locking”, which is a technique used in superconducting dc-SQUIDs. The principle of the method and analysis of performance were presented. It can increase measurement range to 500 times of original one. In another hand, such a superfluid gyroscope should work in a situation with limited angular acceleration. Author presented another method, called “history tracing”, and its work principle. The performance of the second method also be studied, and results showed that “history tracing” overcomes the problem of measurement range totally. Comparisons showed that “history tracing” is a better choice to develop high performance superfluid gyroscope.","PeriodicalId":94036,"journal":{"name":"IEEE/ION Position Location and Navigation Symposium : [proceedings].
