Inter-satellite links for satellite autonomous integrity monitoring

Advances in Space Research, 2011
Abstract A new integrity monitoring mechanisms to be implemented on-board on a GNSS taking advantage of inter-satellite links has been introduced. This is based on accurate range and Doppler measurements not affected neither by atmospheric delays nor ground local degradation (multipath and interference). By a linear combination of the Inter-Satellite

Satellite Monitoring of the Ozonosphere

Russian Meteorology and Hydrology, 2021
The importance of controlling total ozone (TO) and surface ultraviolet irradiance is a reason for continuous monitoring of the ozonosphere using various ground-based and satellite methods and instruments. The global monitoring of TO has been carried out with the Russian instrument IKFS-2 on the Meteor-M No. 2 satellite since 2015.

Satellite Monitoring for Air Quality and Health

Annual Review of Biomedical Data Science, 2021
Data from satellite instruments provide estimates of gas and particle levels relevant to human health, even pollutants invisible to the human eye. However, the successful interpretation of satellite data requires an understanding of how satellites relate to other data sources, as well as factors affecting their application to health challenges. Drawing

Interferometric monitoring of satellite longitudes

International Journal of Satellite Communications and Networking, 2004
This paper proposes a technique for monitoring the longitudinal motion of geosynchronous satellites. A two-antenna interferometer is used, with the baseline orientation adjusted to a particular horizontal azimuth. The interferometer then becomes insensitive to the north–south motion of the satellite, and this enables direct measurement of the satellite'
