A Modified Klobuchar Model Reflecting Characteristics of Ionospheric Delay Error in the Korea Region
Dana Park, Young Jae Lee
https://doi.org/10.11003/JPNT.2023.12.2.121
When calculating the user’s position using satellite signals, the signals originating from the satellite pass through the ionosphere and troposphere to the user. In particular, the ionosphere delay error that occurs when passing through the ionosphere delays…
Ionospheric Model Performance of GPS, QZSS, and BeiDou on the Korean Peninsula
Serim Bak, Beomsoo Kim, Su-Kyung Kim, Sung Chun Bu, Chul Soo Lee
https://doi.org/10.11003/JPNT.2023.12.2.113
Satellite navigation systems, with the exception of the GLObal NAvigation Satellite System (GLONASS), adopt ionosphere models and provide ionospheric coefficients to single-frequency users via navigation messages to correct ionospheric delay,…
A Spoofing Detection Scheme Based on Elevation Masked-Relative Received Power in GPS Receivers using Multi-band Array Antenna
Junwoo Jung, Hyunhee Won, Sungyeol Park, Haengik Kang, Seungbok Kwon, Byeongjin Yu, Seungwoo Seo
https://doi.org/10.11003/JPNT.2023.12.2.101
Many spoofing detection studies have been conducted to cope with the most difficult types of deception among various disturbances of GPS, such as jamming, spoofing, and meaconing. In this paper, we propose a spoofing…
Indoor Path Recognition Based on Wi-Fi Fingerprints
Donggyu Lee, Jaehyun Yoo
https://doi.org/10.11003/JPNT.2023.12.2.91
The existing indoor localization method using Wi-Fi fingerprinting has a high collection cost and relatively low accuracy, thus requiring integrated correction of convergence with other technologies. This paper proposes a new method that significantly reduces…
