Presentation on theme: "Marine and coastal remote sensing"— Presentation transcript:
1 Marine and coastal remote sensing Algeria national capabilitiesThe ALSAT microsatellite programme
2 Remote sensing are becoming a cost-effective techniques Computer technology,Information networks,improvements in sensing systems for satellites.
3 Satellite imagery can used for observing marine features such as: large-scale circulation, currents,river outflow and water quality.This can be visualized by highlighting variations in water color and/or temperature.
4 These observations can be used for activities such as environmental monitoring of sensitive coastal zones,hazards assessment, andmanagement of fishing fleets.
5 Small satellites are enabling developing countries to acces space technology AlSat-1 (Algerian Satellite), an enhanced microsatellite is Algeria's first national satellite.It has been designed and constructed by SSTL (Surrey Space Technology Laboratory) at the Surrey Space Centre (UK).ALSAT-1 is part of an international collaboration of Earth observation satellites specifically designed for disaster monitoring, called Disaster Monitoring Constellation – DMC-.
6 ALSAT-1 CARACTERISTICS Earth observation MicrosatelliteSize: 60 x 60 x 60 cmMass: 90 kgLifetime: yearsLaunch Date : 28 Novembre (Plesetsk Cosmodrome, Russia)Orbit: 680 km (sun-synchronous)Inclination: 98.1°Time : 9h30Operated by: CNTS (Centre National desTechniques spatiales)
24 Circulation générale du 26/08/03 au 13/12/03 Arzew
25 ConclusionAlsat-1 products are free of charge for the marine science community and to the end usersAlsat-1 products along with products of other satellites of the DMC will be used as part of the national marine information database.marine science community is actively participating in the calibration of Alsat-2 senors
