With the rapid development of aerospace technology and the large-scale deployment of low Earth orbit (LEO) constellations, the risk of orbital collisions has increased, creating a growing demand for reliable observations of satellite maneuvers. However, public datasets containing real maneuver records remain scarce. We present MAD-LEO, a Maneuver-Annotated orbital Dataset for LEO satellites. The mission-reported subset contains 1,134 maneuver events from eleven geodetic and altimetry satellites spanning 1992 to 2026, with labels taken directly from mission-published maneuver histories. Each event is checked against two-line element (TLE) data, precise orbit products, and satellite laser ranging (SLR) observations, with evidence tiers assigned according to data availability. The operational subset pairs operator-published ephemerides for 6,785 Starlink satellites with cataloged TLE records over a continuous 107-hour period. Technical validation across seven machine-readable experiment suites confirms the cross-source consistency of the labels and the evidence products.
This study proposes a two-step distributed autonomous orbit determination (AOD) and broadcast ephemeris generation framework and demonstrates that the proposed method reduces the broadcast ephemeris user range error (URE) by more than 19% for GRACE-FO satellites and by 44.4% for a multi-satellite LEO constellation comp...

Global navigation satellite system (GNSS) measurements collected from low Earth orbit (LEO) are useful for a variety of applications including precise orbit determination, space weather monitoring, and terrestrial interference source localization. However, there are few publicly available datasets of multi-GNSS measure...

Precise orbit information is generally unavailable to users of noncooperative low Earth orbit (LEO) communication satellites such as Iridium NEXT, making publicly available two-line element (TLE) data the primary source of orbital states. However, TLE-derived orbital-state errors degrade Doppler positioning performance...

Onboard global navigation satellite system (GNSS) receivers have become the most convenient means to realize autonomous orbit determination and clock estimation for low Earth orbit (LEO) satellites. However, signal outages and blockages in complex space environments cause GNSS observation degradation, which restricts t...
