Details

This project presents the development of a single-frequency GPS-based total electron content measurement tool. It applies ionospheric theories and GPS time delay measurements to effectively monitor electron density.

This project presents the development of a single-frequency GPS-based total electron content measurement tool. It applies theories related to total electron content in the ionospheric layer and the measurement of total electron content using GPS time delay. The tool consists of:

  • An antenna
  • A single-frequency GPS satellite receiver
  • A data processing unit for evaluating and calculating total electron content
  • A display unit for showing total electron content data

The performance was tested by comparing it with the International Reference Ionosphere (IRI) model. The results conclude that the tool can be effectively utilized, with a difference from the IRI model of 50 TECU.

Objective

The objective is to study ionospheric total electron content theories and design a measurement instrument using a single-frequency GPS receiver to analyze electron density data.

The project team developed an instrument to measure total electron density in the ionosphere using a single-frequency GPS satellite receiver. The objectives are:

  • To study theories regarding total electron content in the ionosphere.
  • To design and construct a measurement tool using a single-frequency GPS receiver.
  • To enable the analysis of total electron content data from individual GPS satellites.
