PRAETORIAN SDA_503 — Live Satellite Tracking (NORAD 100061)
Track PRAETORIAN SDA_503 (NORAD catalog number 100061) live on the WatchSat interactive 3D globe above. Its position is propagated in real time from the latest CelesTrak two-line element set using the SGP4/SDP4 orbital model — the same math professional trackers run. It is object C of 2026's 163rd orbital launch (COSPAR designation 2026-163C). It went up together with 20 other satellites from that launch still in the active catalog. As of this element set it had completed roughly 1,335 revolutions of Earth.
Moving at about 7.39 km/s, PRAETORIAN SDA_503 flies in low Earth orbit at an altitude of roughly 939 × 961 km, completing one revolution every 103.9 minutes — about 13.9 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0015). Inclined 81.5° — nearly pole-to-pole — its ground track sweeps essentially every latitude. Its orbital plane crosses the equator northbound at right ascension 222.0°. Earth's equatorial bulge drifts that plane westward about 0.91° per day.

Can you see PRAETORIAN SDA_503 from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, PRAETORIAN SDA_503 is visible only around dawn and dusk, when your sky is dark but the satellite is still sunlit — and whether you can spot it depends on its size and reflectivity. See the “When can I see it?” panel in the live view for when it is above your horizon and sunlit.
