Satellite Imagery - Page 3

They say a picture is worth a thousand words - here is a picture of the ground track of the Jason-1 satellite. This picture shows three track during six hour period. These ground tracks are very similar to that of recon satellites. The width of the track is determined by the height of the satellite and in this case just covers the island of Hawaii. So, regardless of optical resolution, the low satellite ground coverage, cloud cover, and a moving target make the odds of spotting a 53' sailboat in North Pacific very low.
