A GPS Signal Transmission Model for Improved Single Antenna Attitude Determination
This paper describes the development of a GPS transmission model for improving the attitude accuracy by modelling the GPS transmission path. Various factors are considered, such as receiving antenna gain, distance dependent path loss, effects of the ionosphere, GPS satellite transmitting antenna gain and varying GPS satellite transmission power.
The subsequent sections present a new single antenna attitude system based on signal strength. By incorporating a precisely measured spherical antenna gain pattern and a GPS transmission model, attitude can be estimated using a least square search. Finally, the improved attitude system is analysed by comparing to previous results. This paper concludes that further analysis is required for modelling the transmission path, particularly for the ionosphere and the GPS transmitting antenna gain.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
