I’ve started a few new nodes recently. As Toyoo mentioned, the 2 that give you the most data will take about 6 weeks at the moment, with a third taking about 2 months. The others are mostly test satellites and haven’t seen a lot of data coming in lately to begin with. Those will likely take many months (probably around 4-6 months), but that’s also ultimately irrelevant as it won’t really impact how much data your node gets unless they see a large uptick in new data, which I’m not expecting any time soon. So in about 2 months time, you’re pretty much there.
