Calibration and Fusion of GOLD‐Inferred TEC Data With Ground‐Based TEC

Space Weather, Volume 24, Issue 6, June 2026.
Abstract Ground‐based Global Navigation Satellite System (GNSS) receivers provide primary total electron content (TEC) measurements used to monitor ionospheric variability, yet their sparse distribution over oceanic and equatorial regions limits global coverage and model accuracy.

Hybrid system of communication and radio determination using two geostationary satellites

, 1990
A new hybrid satellite system which can provide both communications and positioning services in one system using two geostationary satellites is discussed. The distinctive feature is that location information can be provided by transmitting and receiving

Displaced Geostationary Satellites Using Solar Sailing

, 2016
Solar sailing is a propulsion method using sunlight as energy source, meaning it does not make use of propellants as conventional methods do. The principle of solar sailing is simple: a large lightweight sail acts as a mirror reflecting impinging light ...
