Altitude shells
700km · 38 (5%)770km · 35 (5%)780km · 32 (4%)
Mean altitude ((apogee + perigee) / 2) in 10 km bands, from current orbital elements. Distinct spikes are maintained operational shells; a smear is an uncontrolled or drifting population.
Inclination
74° · 605 (80%)82° · 32 (4%)97° · 22 (3%)
Orbital planes in 1° bands. Several sharp peaks mean the constellation is built from discrete inclination groups, each covering a different band of latitudes.
