A Novel Antenna Array for GPS/INS/PL Integration
نویسندگان
چکیده
In order to improve signal reception performance in GPS/INS/PL (Pseudolite) integration applications, a semi-sphere antenna array is proposed in this paper. It inherits the wide coverage characteristic of conventional spherical arrays and utilizes only about half the number of elements compared to a planar array to cover the upper-semi-sphere space above earth plane. It can process signals from both overhead and horizontal directions at the same time. Thus, unlike common planar arrays, this novel antenna array with a special geometry can receive satellite and Pseudolite (PL) signals from all directions, even from the horizon. Both Capon’s and constraint methods have been used in the simulations of Direction of Arrival (DOA) estimation and beamforming. These simulation results have demonstrated the advantages of the new array.

متن کاملHigh-Accuracy Airborne GPS/INS Positioning Augmented by Pseudolite
GPS/INS integrated systems have been used in mapping applications for direct geo-referencing, which needs very accurate position and attitude solutions. However, due to the limited constellation of GPS satellites and their geometric distribution, the accuracy of GPS positioning cannot meet the requirements of large scale aerial photogrammetry. A GPS/INS integrated system with pseudolite (PL) au...
متن کاملKinematic Positioning with an Integrated GPS/Pseudolite/INS
Although existing integrated GPS/INS systems can overcome inherent drawbacks of each system, such as no result without line-of-sight for GPS and INS errors that grow with time, performance is nevertheless degraded in difficult operational circumstances. Some typical examples are when the duration of satellite signal blockage is excessive, resulting in large accumulated INS errors that are not a...
