Scheduling a constellation of agile earth observation satellites with preemption
In this paper, we consider a scheduling problem for a set of agile Earth observation satellites for scanning different parts of the Earth’s surface. We assume that preemption is allowed to prevent repetitive images and develop four different preemption policies. Scheduling is done for the imaging time window and transmission time domain to the Earth stations as well. The value of each picture ...
متن کاملThe Earth Observation Technology Cluster
The Earth Observation Technology Cluster is a knowledge exchange initiative, promoting development, understanding and communication about innovative technology used in remote sensing of the terrestrial or land surface. This initiative provides an opportunity for presentation of novel developments from, and cross-fertilisation of ideas between, the many and diverse members of the terrestrial rem...
متن کامل1 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...
متن کاملGlobal Earth Observation System of Systems (GEOSS)
What is requested? The Group on Earth Observations (GEO) was established in July 2003 to begin development of the Global Earth Observation System of Systems (GEOSS). GEO is an international partnership espousing the free exchange of Earth observational data. The US participates in GEO and GEOSS through the Interagency Working Group on Earth Observations (IWGEO), a collection of 15 Federal agenc...
متن کاملOptical Data Downlinks from Earth Observation Platforms
The increasing resolution of earth observation sensors will require much higher data rates for the data downlink in future than is feasible with conventional RF-technology. This applies for earth observation satellites as well as for aeronautic observation platforms, such as aircraft or stratospheric high altitude platforms. The most promising solution for this data downlink bottleneck is the a...
