ABSTRACT
This paper analyzed geomagnetic variation of H-component from several geomagnetic stations in Indonesia, that are Kototabang (KTB), Pontianak (PTN), Tanjungsari (TJS), Pare-pare (PRP), Manado (MND), Kupang (KPG), and Pamengpeuk (PMK) during 2014. The study aims to analyze and obtain data set that are suitable for PTN geomagnetic data so that they can fill in the data gaps of PTN. We performed data analysis using standard deviation for PTN and other stations. We found that KPG, MND, PMK, and PRP have smaller deviation standard about 10 nT at geomagnetically quiet conditions. Meanwhile, in disturbed conditions, the maximum standard deviation is 17 nT. Substitution of data for geomagnetic quiet conditions should be done with caution and requires further analysis. The substitution of data for disturbed conditions can be done safely because the maximum standard deviation is smaller than the range of disturbance conversion into K index.

TEC variation over an equatorial and anomaly crest region in India during 2012 and 2013
Using the global positioning system (GPS) measurements, the total electron content (TEC) at station Bangalore (13.02°N, 77.57°E geographic; 04.44°N, 150.84°E geomagnetic), lying at the equatorial region, and station Lucknow (26.91°N, 80.95°E geographic; ...
Elevation-dependent pseudorange variation characteristics analysis for the new-generation BeiDou satellite navigation system
To validate the new system design and the new technology of the third-generation BDS (BeiDou-3), five non-GEO experimental satellites were launched during 2015 and 2016. In addition to the B1I and B3I signals that have been emitted by BeiDou-2, three ...
Relationship between GIX, SIDX, and ROTI ionospheric indices and GNSS precise positioning results under geomagnetic storms
AbstractIonospheric indices give information about ionospheric perturbations, which may cause absorption, diffraction, refraction, and scattering of radio signals, including those from global navigation satellite systems (GNSS). Therefore, there may be a ...
