摘要: The ionospheric Total Electron Content (TEC) can be obtained from processing measurements of the dual-frequency Global Positioning System (GPS) receiver. main sources errors in TEC calculation are satellite and receiver biases. In this paper, we apply gradient descent algorithm on bias estimation. is derived at 12 GPS stations Thailand. criterion estimation based minimum sum vertical (VTEC) standard deviation method. results show that maximum value approximately 3.69 ns UDON station, while −5.91 SRTN station. accuracy biases compared with reference percentage about 7.5% VTEC between method proposed all less than 0.05%. Thus, a viable option to estimate bias.
