NUSAT-39 (TIKVAH ALPER) — Live Satellite Tracking (NORAD 56201)
Track NUSAT-39 (TIKVAH ALPER) (NORAD catalog number 56201) 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 Z of 2023's 54th orbital launch (COSPAR designation 2023-054Z). 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 19,115 revolutions of Earth.
Moving at about 7.67 km/s, NUSAT-39 (TIKVAH ALPER) flies in low Earth orbit at an altitude of roughly 417 × 427 km, completing one revolution every 92.9 minutes — about 15.5 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0007). Its 97.3° retrograde, near-polar inclination is characteristic of a Sun-synchronous orbit — the type Earth-imaging and weather satellites use to revisit each spot at the same local solar time. Its orbital plane crosses the equator northbound at right ascension 160.9°. Earth's equatorial bulge precesses that plane eastward about 1.02° per day, matching the Sun's apparent motion — which is what holds its lighting constant.

Can you see NUSAT-39 (TIKVAH ALPER) from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, NUSAT-39 (TIKVAH ALPER) 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.
