6. 10/12/2015 GEM 3366 6 RESURS-01 –Russian satellite –Launched first series in 1985 –Operated for 3 years and a second satellite launched in 1988 which served for 7 years –Third satellite began in 1994

7. 10/12/2015 GEM 3366 7 –Satellites carry MSS with spatial resolution of 170m in four visible and near IR bands –From 678km, the system has a revisit interval of 4 days –Size of the scene is 600x600km

8. 10/12/2015 GEM 3366 8 ADEOS –Japanese satellite –Advanced Earth Observing Satellite (ADEOS), launched in 1996 –Carry two primary sensing systems Advanced Visible and Near Infrared Radiometer (AVNIR) Ocean Color and Temperature Sensor (OCTS) –AVNIR data collected in four-band MS mode –OCTS records 8 bands in the visible and near IR and 4 bands in the thermal region

9. 10/12/2015 GEM 3366 9 JERES-1 –Primarily as a radar remote sensing mission –Launched in 1992 –Carried an Optical Sensor (OPS) which captures spatial resolution of 18x24m –Employs pushbroom scanning in 7 bands in the visible, near IR, and mid-IR

10. 10/12/2015 GEM 3366 10 High Resolution land satellites –Numerous launched, or are in development –Examples: SPIN-2 IKONOS QuickBird OrbView-3 EROS

11. 10/12/2015 GEM 3366 11 SPIN-2 –Russian (first mission in 1998) –Space Information-2 (SPIN-2) –Data is produced by digitizing panchromatic photographs taken by a particular camera called KUR-1000 –Altitude of 220km –Individual scenes of 40x160km

12. 10/12/2015 GEM 3366 12 IKONOS –Launched in 1999 –Repeats every 11 days –Image coverage is 11x11km –Collects data in four bands at a ground resolution of 4m –System is highly maneuverable (can zoom in and out)

13. 10/12/2015 GEM 3366 13 QuickBird –By EarthWatch Inc. –Launched in 2001 –High resolution data obtained at an altitude of 600km –Average revisit time is 1 to 5 days –1m resolution panchromatic sensor and the four band sensor with a resolution of 4m

14. 10/12/2015 GEM 3366 14 OrbView-3 –By ORBIMAGE –Launch in mid-2000 –Altitude of 420km –Repetition is less than 1.5 days with OrbView-3 and OrbView-4 operating simultaneously –Includes panchromatic band (1m resolution), and four MS bands (3m resolution)

15. 10/12/2015 GEM 3366 15 EROS –By ImageSat International –Joint between Israel Aircraft Industries and Core Software Technologies –Two EROS A+, launched in 2000, and 2001 –Pushbroom scanning by these panchromatic systems –Resolution of 1.8m and 16km swath width

16. 10/12/2015 GEM 3366 16 Meteorological satellites –Assist in weather prediction and monitoring –Use sensors that have coarse spatial resolution –Various countries have launched various metsats –Three well known metsats (US based are: National Oceanic and Atmospheric Administration (NOAA) Geostationary Operational Environmental Satellite (GOES) Defense Meteorological Satellite Program (DMSP) –All carry a range of meteorological sensors

17. 10/12/2015 GEM 3366 17 Ocean monitoring satellites –2/3 of the earth is covered by water –Satellites provide synoptic views of the oceans over large areas and extended over time –Examples: Seasat –Operate in the microwave portion of the spectrum Nimbus-7 –Also called Coastal Zone Color Scanner (CZCS) –Measures color and temperature of coastal zones –Carry ocean specific sensors
