About This Satellite
Lincoln Calibration Sphere 1, launched in 1965, is a 1.1-metre aluminium sphere used as a radar-calibration target. Its precisely known shape and orbit allowed radar sites to verify their tracking accuracy for decades.
LCS 1 is a cataloged satellite tracked under NORAD ID 1361 with international designator 65034C. According to the GCAT master catalog, it was built by ROHR/MITLL, on the LCS platform, with a launch mass of about 34 kg, with a shape described as Sphere. According to the TLE snapshot used when this page was generated (2026-08-18), its MEO orbit had an apogee of about 2.806 km and a perigee near 2.784 km, with an inclination of 32.15° and a period of roughly 145.6 minutes; at apogee its speed was about 6.59 km/s. Positions on this page are near-real-time SGP4 predictions propagated from the latest two-line element (TLE) data.
In the TLE snapshot used to generate this page, LCS 1's apogee was 2.806 km, where its speed was about 6.59 km/s, completing about 9.9 orbits of Earth per day. Track it live on the map above or in the JOT orbital map.
