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

Journal Scientific and Applied Research, 2014
n the current paper, satellite methods for research of gas content of the atmosphere are presented. The stress is on the satellite methods and the measurement geometry. A generalized characteristic of the absorption specters of the atmospheric ozone and gases into the optic range is presented when research with land and satellite appliances and ...

Monitoring agriculture areas with satellite images and deep learning

Applied Soft Computing Journal, 2020
Agriculture applications rely on accurate land monitoring, especially paddy areas, for timely food security control and support actions. However, traditional monitoring requires field works or surveys performed by experts, which is costly, slow, and ...

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

Satellite monitoring of development

Science, 2021
Sustainability Recent years have witnessed rapid growth in satellite-based approaches to quantifying aspects of land use, especially those monitoring the outcomes of sustainable development programs. Burke et al. reviewed this recent progress with a particular focus on machine-learning approaches and artificial intelligence methods. Drawing on examples

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'

Monitoring Earth and Sun by Satellite

Science, 1987
Researchers attending the spring meeting of the American Geophysical Union held 18 to 21 May in Baltimore have grown familiar with doing geophysical studies by satellite. Here are three current examples discussed at the meeting: gauging the output of the sun, measuring crustal movement, and deciphering the mineral composition of surface rocks.

Satellite monitoring of disturbances in Arctic ecosystems

2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
This study explores the capability of satellite remote sensing to detect relatively rapid changes of vegetation cover in northern Fennoscandian regions in response to disturbance more generally, and insect defoliation damage in particular. The data used is a long term time series of leaf area index (LAI) at 8Km resolution derived from the Advanced Very

Satellite Monitoring of Volcanoes

1996
Ever-increasing population densities of volcanic regions around the world dictate that the potential risks of any eruption are also increasing. Rapid developments in remote-sensing science in recent years vastly expand our capabilities to monitor volcanoes across the entire electromagnetic spectrum.
