BISONSAT — Live Satellite Tracking (NORAD 40974)
Track BISONSAT (NORAD catalog number 40974) 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 L of 2015's 58th orbital launch (COSPAR designation 2015-058L). It went up together with 11 other satellites from that launch still in the active catalog.
Moving at about 7.67 km/s, BISONSAT flies in low Earth orbit at an altitude of roughly 460 × 578 km, completing one revolution every 94.9 minutes — about 15.2 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0086). Inclined 64.8° to the equator, it overflies every latitude up to about 65° north and south. Its orbital plane crosses the equator northbound at right ascension 269.5°. Earth's equatorial bulge drifts that plane westward about 3.24° per day.

About the Other Active Satellites group
BISONSAT 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 BISONSAT from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, BISONSAT 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.
