Introduction to GPS/GNSS technology AmitKumar, ...George P.Petropoulos, inGPS and GNSS Technology in Geosciences, 2021 4.5GPS ephemeris errors The position of each satellite in the constellation is a function of time because they keep on moving with respect to time. It is included in broadcast...
On the other hand, coal mining led to land subsidence and the destruction of underground aquifers, affecting the regulation and storage of runoff by the groundwater system, resulting in a decline in groundwater levels and a sharp decrease in surface runoff [46,47]. These indirectly led to ...
A survey was conducted in the study area to verify the spatial distribution of serpentinized areas and other hydrothermally altered and lithological units using both GNSS solution (accuracy of cm) and handheld GPS (average accuracy of 3 m). Moreover, during flight missions, we took the samples...
LAND COVER:NASA Earthdata is also an excellent source of global land use and cover. But it’s not just your typical land cover classes. It has specialized satellite-derived data like permafrost and wetland types. Our suggestion is to start with a simple search. Then, change the time range ...
land-survey mini-satelliteattitude controlWe consider problems on calibration and alignment of spacecraft attitude determination system with a sun-magnetic correction, discrete filtering of measurements, synthesis of control algorithms and dynamical analysis of the attitude control system for a land-survey ...
On the other hand, the inconsistency between real-time measurement and the database is the main error source in database matching. Such inconsistency may be caused by the existence of new environments and varying environments and other factors. The survey paper (Li et al. 2020a) has a ...

A complete survey of the studied zone can be provided, depicting the significant sources of air pollution (factories, dumps, thermal power plants, road transport, etc.) and indicating the relationships between activities in a city and the distribution of air pollution concentration [14]. ...
In order to allow IFAD to single out areas for further agricultural activities, the trial produced land- cover maps and digital models of the area's slope and drainage system to pinpoint areas prone to flooding. "With these products, we can get details about the land and develop action ...
