Oneliner	Two tiny S-band satellites to jumpstart a low-Earth-orbit constellation using spectrum gained through its acquisition of Helios Wire.
Results	Performed 110 km in altitude orbit raise from TLEs as reported by Jonathan McDowell. The orbit raising required about 65 meters per second. Jonathan McDowell reported on 2021-12-03 that new TLE out today for Echostar EG-3 (48892) shows it in a 650 x 677 km x 96.0 deg orbit - first TLE in a month, Nov 3 it was in a 644 x 666 x 97.5 deg orbit, corresponding to a 1.5 deg inclination change. It is about 200 m/s.
