| Q. | Why do passes for the ISS sometimes appear on the special ISS pages, but not on the "All satellites" page? |
| A. | The reason is because we have a lower elevation limit of just 10° for the ISS
because it is so bright and can be seen closer to the horizon. The "All satellites" page, however,
has an elevation cut-off of 20°, because most satellites are difficult to spot lower than this.
So if an ISS pass reaches a maximum elevation of 15°, it will appear on the ISS passes page,
but will be missing from the "All sats" page because it doesn't achieve the required minimum
elevation. |
