| Özet |
| This study investigates effects of static versus kinematic CSRS-PPP processing on coordinate differences (Δ φ, Δ λ, Δ h) during the 2023 Kahramanmaraş earthquake sequence in Türkiye. GNSS data from TNPGN-Active stations MAR1 and ANTE are analyzed across 10 pre-seismic days (January 28-February 6, 2023) using two approaches: daily spectral analysis with median filtering, detrending and FFT and combined analysis of concatenated time series. Results show processing modes produce discrepancies exceeding 35% in dominant frequency characteristics and 68% in spectral variance. We observe a counterintuitive distance paradox: ANTE station exhibits 87.5% higher baseline frequency variability despite being 46% farther from the epicenter than MAR1. Statistical analysis (p< 0.001) confirms these differences represent fundamental measurement uncertainties. The height component consistently … |
