Minimum Elevation Explained
Understand how minimum elevation settings affect satellite filtering and pass quality in MySatVis.
What Elevation Means
Elevation is the angle above your local horizon. A value of 0 deg is at the horizon and 90 deg is directly overhead.
Why Use A Higher Threshold
Raising minimum elevation helps remove shallow passes that are harder to observe due to haze, buildings, or terrain.
Practical Starting Point
A threshold around 20 to 30 deg is a common practical range for cleaner pass selection.
Frequently Asked Questions
Does minimum elevation change orbit calculations?
No. It only changes how visibility results are filtered and presented.
Should I set minimum elevation to zero?
Zero captures every horizon crossing, but many low passes are difficult to observe in real-world conditions.
