The imagery varies in spatial resolution 10 500m pixel revisit periods 2 16 days and spectral bands contained 4 to 12 bands.
Ers 1 satellite spatial resolution.
The satellite is 11 8 m tall the solar panel is 11 7 x 2 4 m the sar antenna is 10 x 1 m and the total mass is 2516 kg.
The satellite was put into a sun synchronous polar orbit at an altitude of 782 785 km.
This data set comprises low resolution browse products of system corrected fast delivery ers sar data fdc of the european remote sensing satellite ers 1.
Ers 1 cospar 1991 050a launched 17 july 1991 from guiana space centre aboard an ariane 4 rocket.
The orbit has a 12 day repeat cycle and completes 175 orbits per cycle.
250 km to the right of the satellite track.
A satellite sensor with large area coverage and fairly coarse spatial resolution would be excellent for monitoring the general state of vegetation health over alberta saskatchewan and manitoba.
Ers 1 failed on 10 march 2000 far exceeding its expected lifespan.
Across track 26 3 m.
Radiometric resolution 0 1 k.
Mid swath 23 deg.
The large east to west expanse would be best covered by a sensor with a wide swath and broad coverage.
Along track 1 km.
This instrument has a spatial resolution of down to 5 m and a swath of up to 400 km.
Ers 2 is nearly identical to ers 1.
Spatial resolution 1 km x 1 km ifov at nadir.
Along track 30 m.
Swath width 500 km.
Compared to ers 1 ers 2 is equipped with additional instruments that measure the ozone content of the atmosphere and monitor changes in vegetation cover more effectively.
This would also imply that the spatial resolution of the sensor would be fairly coarse.
Near swath 20 1 deg.
Radiometric resolution 0 1 k.
As one of the key instruments on the ers 1 and 2 satellites the sar is a high resolution wide swath imaging radar producing high quality images of the oceans coastal zones polar ice and land regions irrespective of weather conditions and cloud coverage or whether it is day or night.
On line access is offered by means of the intelligent satellite data information system isis a service of the dfd within dlr at oberpfaffenhofen germany.
The constellation is on a sun synchronous near polar 98 18 orbit.
Absolute accuracy 0 5 k by averaging over a 50 km x 50 km area for sst with 80 cloud cover.
Across track 0 9 km.
The web satellite data service landviewer alone gives access to 8 free earth observation datasets.
