OPS 6073 (DMSP 4A F2)

About This Satellite

OPS 6073 (DMSP 4A F2) is listed as a payload under NORAD ID 2669 with international designator 1967-010A. According to the GCAT master catalog, it was built by RCA, on the DMSP Block 4A platform, with a catalog mass of 79 kg, with a shape described as Oct Cyl. It is associated with United States of America. In the historical build snapshot (TLE epoch 2026-09-04), its LEO orbit had an apogee of about 833 km and a perigee near 762 km, with an inclination of 99.11° and a period of roughly 100.8 minutes; at apogee its speed was about 7.42 km/s. It was launched on 1967-02-08. The build snapshot uses a TLE with epoch 2026-09-04. A moving map, when available, is a prediction rather than a direct measurement.

What this identity tells us

The payload classification comes from GCAT record S02669. A catalog identifier follows a tracked physical object, not necessarily an active service. Manufacturer and owner entries describe catalog associations; ownership is not interchangeable with present-day operation. A separately sourced mission history has not yet been verified for this record.

Reading this orbital snapshot

Based on TLE epoch: 2026-09-04. Estimated altitude ranges from 762 km at perigee to 833 km at apogee, a difference of 71 km. The orbital period is about 100.8 minutes. Eccentricity 0.00493 indicates a nearly circular path. In a two-body approximation, perigee speed is 1.01 times apogee speed. These are mean-element estimates, not instantaneous measurements. Distance per orbit uses an ellipse approximation.

Saved build snapshot. If a valid TLE is retrieved, this explanation and the orbit panel update together. Otherwise this dated snapshot is retained.

Ground track is not sensor coverage

An inclination of 99.11 degrees implies approximate geocentric ground-track limits of 80.9 degrees north and south. This is a retrograde orbit, moving against the direction of Earth rotation. The plotted line marks the point beneath the object. It does not represent camera coverage, radio reception, or a guaranteed visible pass.

Accuracy and missing information

The introductory record describes the build snapshot. The orbital snapshot explanation and orbit panel share any successfully retrieved TLE; check the displayed epoch. Reentered objects retain historical data only. Mission history is not rewritten by TLE updates. TLE/SGP4 positions are predictions and can change after maneuvers or updated observations. The 14-day stale-data cutoff is a display safeguard, not an accuracy guarantee. Local passes are geometric predictions, not a visibility forecast. No verified operator or mission status means unknown, not active. Do not use this catalog for collision avoidance or operational flight decisions.
