Starlink for sure. As mentioned above, they are launched 60 at a time to a low altitude, and then each one maneuvers to a higher (and invisible) altitude of about 340 miles. The next batch is now set to go up March 22. They'll be launching them two to three times a month for the foreseeable future. They need about 2,000 of them to get global internet service, but they are designed to be short-lived so they can be replaced with improved models as the technology improves. They also de-orbit themselves when they're done and burn up completely.
The new ones to come will talk to each other via lasers, reducing or eliminating the need for ground "repeater" stations entirely and allowing for total ocean and airliner coverage.
