ATTITUDE RESTITUTION FOR MULTISPECTRAL EARTH OBSERVATION SATELLITE USING SPACE TRIANGULATION TECHNIQUE

Detecting Phytoplankton Size Class Using Satellite Earth Observation

1 Earth Observation – Space Technology

For monitoring of the Earth thousands of satellites have been sent into space on missions to collect data related different spheres of the Earth investigations and studies. Today, the ability to forecast weather, climate, and natural hazards, environmental monitoring and ecological issues depend critically on these satellite-based observations. Based on this data it is possible to gather satell...

Satellite earth observation in operational oceanography

The role and contribution of satellite data in operational oceanography is reviewed, with emphasis on northern European seas. The possibility to observe various ocean parameters and processes by existing satellite sensors, such as optical instruments, infrared radiometers, passive Ž . microwave radiometers, and active microwave systems altimeter, scatterometer, SAR is discussed. The basic param...

Modeling Earth Observation Satellite Data Semantically

This paper presents preliminary research results on using semantic technologies to model Earth observation satellite data. The research goal is to enhance the data search functionalities that satellite data catalogues provide to researchers and practitioners. An ontology that captures characteristics of satellite data is introduced. How to utilize this ontology in assisting data search and how ...

Automated Planning for Earth Observation Spacecraft under Attitude Dynamical Constraints

Agile Earth observation missions continuously require a large amount of planning during the spacecraft’s observations. Beside priorities of the observation sites, especially the agility constraints of the satellite are important to be taken into account during the planning process. This is due to the body-fixed instrument’s line of sight, requiring the whole satellite to point to the observatio...
