Satellite clocks characterization and monitoring for global navigation satellite systems
2011 XXXth URSI General Assembly and Scientific Symposium, 2011In Global Navigation Satellite Systems (GNSS) the user's position is determined measuring the time of flight of the signals broadcast from satellites, which is proportional to the distance between the user and each satellite of the constellation. Time and frequency metrology has an essential role in satellite navigation systems: since a distance can be

Satellite Monitoring of Volcanoes
1996Ever-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.

Volcano monitoring by satellite
Geology Today, 1989‘St Pierre, in the morning throbbing with life, thronged with people, is no more. Its ruins stretch before us, wrapped in their shroud of smoke and ashes, gloomy and silent, a city of the dead’. Thus was St Pierre described by the Vicar‐General of Martinique in the aftermath of the 8 May 1902 eruption of Mt Pelée.

Reservoir Monitoring Using Radar Satellites
Asia Pacific Oil and Gas Conference & Exhibition, 2009Abstract Description of the material InSAR (Interferometry for Synthetic Aperture Radar) technology is a spaceborne measurement method, capable of detecting ground motion with millimetric exactness using radar satellite images. Measurements are taken remotely, from the space.

10th International Conference on Digital Satellite Communications (ICDSC-10), 1995
To effectively manage a satellite communications network, it is necessary to monitor the performance of the carriers within that network. The carrier power, center frequency, and bandwidth of each carrier must be monitored to fully utilize the space segment resources.

Satellite monitoring of phenological events
International Journal of Biometeorology, 1976A technique used to investigate broad scale phenological events by means of repetitive satellite observations is described. The temporal sequence of leaf development and senescence of deciduous forest and crop canopies is characterized by changes in their reflectance of solar energy at several wavelength intervals.

Monitoring Earth and Sun by Satellite
Science, 1987Researchers 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 Stereo Images for Risk Monitoring [PDF]
, 2013 Surface monitoring is essential to understand the spatial and temporal evolution of complex landscape modifications and instabilities related to road and railway infrastructures. In recent years, the terrain change detection methods have evolved particularly with the development of increasingly automatic extraction procedures of both DTM and DSM ...
