Users can leverage the Mission Awareness tool to understand potential satellite access opportunities for a specific task and plan the cadence of a repeat task. The Mission Awareness tool generates a Comma Separate Value (CSV) file with the list of potential satellite access times and the associated metadata.

Column Name |
Description |
Unit |
|
Center WGS84 |
Point object for the center point of the access opportunity in the WGS84 coordinate system. |
Point |
|
Center ECEF |
Point object for the center point of the access opportunity in the Earth-centered, Earth-fixed (ECEF) coordinate system. |
Point |
|
Spacecraft ID |
Capella spacecraft set to perform collection. |
Number |
|
Access ID |
A unique identifier for a potential satellite access time. |
String |
|
Access Request ID |
A unique identifier for the submission to Mission Awareness. |
String |
|
Window Open |
Earliest time when acquisition can occur. Image acquisition can begin any time after the Window Open time up to the Window Close time. |
Datetime |
|
Window Close |
Latest time when acquisition can occur. Image acquisition can begin any time after the Window Open time up to the Window Close time. |
Datetime |
|
Orbital Plane |
The regular, repeating path of the spacecraft around the Earth. Capella spacecrafts are in mid-latitude (47 degrees and 53 degrees) orbits. |
Number |
|
Orbit State |
Whether the spacecraft is on the Ascending (South to North) or Descending (North to South) orbit during image acquisition. |
String |
|
Look Direction |
Whether the spacecraft is looking Left or right with respect to its velocity vector during image acquisition. |
String |
|
Local Mean Time |
Local time at center of access opportunity in astronomical time (seconds). |
Number [Seconds] |
|
Az Open |
Counterclockwise angle with respect to the azimuth open in the topocentric geodetic ENZ coordinate system. |
Number |
|
Az Close |
Counterclockwise angle with respect to the azimuth close in the topocentric geodetic ENZ coordinate system. |
Number |
|
Elev Min |
Minimum angle between the tangent to the surface and the line of sight of the satellite as seen from center point during the access window. |
Number |
|
Elev Max |
Maximum angle between the tangent to the surface and the line of sight of the satellite as seen from center point during the access window. |
Number |
|
Off-Nadir Min |
Minimum look angle between the spacecraft’s nadir position and the SAR beam in degrees. |
Number [Degrees] |
|
Off-Nadir Max |
Maximum look angle between the spacecraft’s nadir position and the SAR beam in degrees. |
Number [Degrees] |
