Algorithm Research Using GNSS-TEC Data to Calibrate TEC Calculated by the IRI-2016 Model over China

Regularized Estimation of TEC from GPS Data for Certain Midlatitude Stations and Comparison with the IRI Model

Regularized estimation of Total Electron Content (Reg-Est) is a novel technique which can combine signals from all the satellites for a given instant and given station and estimate the vertical TEC (VTEC) values for any desired period without missing any important features in the temporal or spatial domain. The preprocessed signals from all the satellites that are received for a certain time pe...

Monitoring the TEC variation using pattern matching method during earthquakes as determined from ground based TEC measurement and satellite data

Total electron content (TEC) data, obtained from GPS satellites can be used as a tool for extracting earthquake precursor. In this paper, a pattern matching technique is used for monitoring TEC variation during and prior to the earthquake. For the experiment two major earthquake events i.e. Bhutan earthquake on 21st September 2009 and Nepal earthquake on 25th April 2015 are considered for analy...

TEC and TEC Controller for Temperature-Stabilized Plate

To obtain accurate measurements for brightness temperature from the IIP radiometer, it is necessary to know the temperature of the front-end components especially low noise amplifier (LNA) and microwave terminator during measurements. For this application, all of these components will be placed on a temperature-stabilized metal plate which can be achieved by using a thermoelectric cooler (TEC)....
