| Mar 30, 2018 at 14:32 | comment | added | uhoh | So DigitalGlobe's plan is to use something like six or seven polar orbits with three satellites in each orbit? Or is this just a proof of concept? | |
| Mar 30, 2018 at 13:23 | comment | added | asdfex | The ground track of ISS is maybe a good reference - it spends a substantial time over interesting regions and crosses Europe 3-4 times a day. Half of these are during night. With some optimizations to inclination and orbital period, it should be able to take one image a day of any place in Europe - times 24 to cover 12 hours of daylight each 30 minutes. | |
| Mar 30, 2018 at 11:34 | comment | added | uhoh | Thanks, I'm having trouble understanding what this collection of orbits really looks like. Can you describe the hypothetical constellation a bit more? Is this a single ring of 20 satellites in a single, near-equatorial ring, or six to eight polar orbits with three each? It's hard to know if the number 20 is right without a clear enough description of the constellation to test it. This is why I tried to indicate that an answer which referred to their actual plans is what I'm hoping for. | |
