GPS Receiver and Satellite DCB Estimation using Ionospheric TEC [PDF]
Journal of Astronomy and Space Sciences, 2009 We estimated the receiver and satellite differential code bias (DCB) based on the ionospheric total electron content (TEC) estimation method. The GPS network which has been operated by the Korea Astronomy and Space Science Institute (KASI) was designed ...

Differential Code Bias Estimation using Multi-GNSS Observations and Global Ionosphere Maps
Navigation, 2014 Measurements of Global Navigation Satellite System (GNSS) receivers are affected by systematic offsets re- lated to group and phase delays of the signal generation and processing chain. The resulting code and phase biases depend on the transmission frequency and the employed signal modulation. Within this study differential code biases (DCBs) of legacy

Determination of NavIC differential code biases using GPS and NavIC observations
Geodesy and Geodynamics, 2020 Delay bias between the pseudo range code is called Differential Code Bias (DCB), this is one of the main error sources to estimate the precise Total Electron Content (TEC) in ionosphere.

Simulation of spin-polarized scanning tunneling microscopy on complex magnetic surfaces: Case of a Cr monolayer on Ag(111) [PDF]
, 2011 We propose an atom-superposition-based method for simulating spin-polarized scanning tunneling microscopy (SP-STM) from first principles. Our approach provides bias dependent STM images in high spatial resolution, with the capability of using either ...
