NUSAT-37 (JOAN CLARKE) — Live Satellite Tracking (NORAD 56203)
Track NUSAT-37 (JOAN CLARKE) (NORAD catalog number 56203) 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 AB of 2023's 54th orbital launch (COSPAR designation 2023-054AB). It went up together with 11 other satellites from that launch still in the active catalog. As of this element set it had completed roughly 19,144 revolutions of Earth.
Moving at about 7.69 km/s, NUSAT-37 (JOAN CLARKE) flies in low Earth orbit at an altitude of roughly 379 × 383 km, completing one revolution every 92.0 minutes — about 15.6 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0003). Inclined 97.3° — nearly pole-to-pole — its ground track sweeps essentially every latitude. Its orbital plane crosses the equator northbound at right ascension 159.2°. Earth's equatorial bulge precesses that plane eastward about 1.03° per day, matching the Sun's apparent motion — which is what holds its lighting constant.

NUSAT-37 (JOAN CLARKE) is one of 4,471 active satellites in WatchSat's general catalog — the broad population of Earth-observation, communications, science, amateur-radio and technology spacecraft outside the giant broadband constellations. Browse all other active satellites live in 3D.
Can you see NUSAT-37 (JOAN CLARKE) from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, NUSAT-37 (JOAN CLARKE) 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 pass predictions for your location for when it is above your horizon and sunlit.
