This is physically impossible due to Sentinel-1 using a SAR (Synthetic Aperture Radar) sensor instead of an optical sensor. You can create false color RGB images from SAR data but no true color RGB. If you are looking for optical remote sensing imagery, besides Landsat, the recently launched Sentinel-2 is expected to deliver it's first images soon.


From the IGS Galileo status it appears that there are "standard" PRNs assigned - as of Sep 15, it looks like E followed by the SV ID for the operational satellites. Obviously that could change as satellites are "refreshed". From that same web site, it is also possible that different receivers will report different values for the same satellite. The ...


Together Terra and Aqua image the entire Earth every 1 to 2 days. The cross track swath is about 2330 km (about 3000 km is needed for "true" daily global coverage). Compared to the geostationary satellites (35,786 km), sun synchronous satellites fly relatively low (600 to 850 km), their swath is thus smaller for a similar viewing angles. The fact that ...


You see the data that the satellites really gathered. On some places of the earth, no satellite has crossed during the day, hence you see nothing for that day. It seems that the satellite swaths intersect in the North and South, but not around the equator. If you switch between AQUA MODIS and TERRA MODIS, you see that the direction of the two swaths are ...
