Research ArticleOpen accessIn the keywordsSynthesis of Optimal Incoherent Subcarrier Tracking of BOC(1,1) Navigation SignalsAlexandr Ivanovich PerovNavigation receivers of global positioning systems that are operated in complex electromagnetic environment must have an increased noise immunity characteristic. One way of such noise immunity rising is to use incoherent operating mode of navigation receiver. There are known processing algorithms for navigation signals with Binary Phase Shift Keying (BPSK) modulation. But in the near-term outlook Global Navigation Satellite Systems … …American Journal of Applied Sciences, Vol. 13, Issue 9 · 26 Sep 2016 · 7,169 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGPS Ionospheric Total Electron Content and Scintillation Measurements during the October 2003 Magnetic StormMohammad Awad Momani, Takialddin A. Al Smadi, Farouq M. Al Taweel, Khaldoon A. GhaidanProblem Statement: Ionospheric scintillations, cause significant effects on satellite signals for communication and navigation in equatorial region and polar regions mainly during sever magnetic storms periods. This phenomenon is not fully understood due to few studies performed. The study investigates variability of Total Electron Content (TEC) and ionospheric scintillation during October 2003 magnetic storm over Antarctica using ground based GPS … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 2 · 13 Jul 2011 · 8,514 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTEC and Scintillation Study of Equatorial Ionosphere: A Month Campaign over Sipitang and Parit Raja Stations, MalaysiaM. Abdullah, A. F.M. Zain, Y. H. Ho, S. AbdullahProblem Statement: Ionospheric scintillations, which cause significant effects on satellite signals for communication and navigation, often takes place in equatorial region such as Malaysia. However, this disturbance are not fully understand due to few studies performed. This research reports the study and monitoring activity on Total Electron Content (TEC) and ionospheric scintillation in Malaysia using GPS measurements. Approach: One dual-frequency … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 9,506 accessesView PDF Cite
