Field of view. Landsat satellites by design have a rather narrow field of view (185 km across) so as to reduce issues with off-nadir resolution while Amazonia-1 by design has a much wider field of view (850 km) so as to reduce the time delay between repeated observations of the same locale. The key sensor on Amazonia-1 is the Advanced Wide Field Imaging ...

Landsat orbits repeat their ground tracks almost exactly every sixteen days. Each Landsat sees some part of the Amazon three to six times per day, as the ground tracks @Alfonso Gonzalez posted show, but the interval between one Landsat swath of some part of the Amazon and the next image of the same part of the Amazon by the same Landsat imager, for greatest ...

Sun-synchronous orbits are useful for global coverage since they are near polar orbits. Attached is the plot of the groundtracks of Amazonia-1 and Landsat-7 for a 24 hour period. So in one day, each of the satellites makes 2 passes over the Amazon. However the Amazon is massive, and the flyovers are on the order of tens of minutes, so full coverage of the ...
