About This Satellite
Amazonia 1 launched on February 28, 2021 to support land-cover monitoring, including deforestation and agriculture. INPE describes it as the first Earth-observation satellite designed, integrated, tested, and operated exclusively by Brazil. Its contribution is broad-area optical imagery that can be examined alongside other environmental datasets.
Four bands observe a wide strip of land
INPE's data catalog specifies blue, green, red, and near-infrared bands at 64-metre spatial resolution, an 850 km imaging swath, and a five-day revisit. Swath width and pixel resolution describe different scales: a wide regional image is not the same as a detailed photograph of an individual building.
Digital numbers and surface reflectance are different products
The catalog distinguishes corrected Level-2 digital-number imagery, orthorectified Level-4 digital numbers, and Level-4 surface reflectance with a cloud mask. Select the processing level deliberately before comparing brightness across dates. A visually similar image does not necessarily contain the same physical quantity or the same corrections.

The satellite can record images outside ground-station view
INPE describes a payload chain in which WFI images and auxiliary data pass through processing electronics to the Digital Data Recorder. Stored or real-time data can then reach the ground through the image-data transmitter during a contact. This separates acquisition time from downlink time and allows imaging beyond the region visible to a receiving station. A predicted pass is therefore not the complete imaging schedule.

Test images and released products marked different milestones
INPE's July 26, 2021 notice states that Amazonia-1 passed commissioning review and its images could be made available to the public. It also points readers to a catalog manual and processing-level documentation. That announcement establishes a historical release milestone, not the quality of every later scene. For an actual analysis, retain the acquisition date, cloud information, and product documentation with the downloaded data.

Reading this orbital snapshot
Based on TLE epoch: 2026-09-05. Estimated altitude ranges from 754 km at perigee to 757 km at apogee, a difference of 3 km. The orbital period is about 99.9 minutes. Eccentricity 0.00023 indicates a nearly circular path. In a two-body approximation, perigee speed is 1.00 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 98.43 degrees implies approximate geocentric ground-track limits of 81.6 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.
