atmospheric_drag¶
Monte-Carlo sampling of errors due to atmospheric drag force uncertainty.
Estimate a power-law model of error standard deviation in along-track direction (largest error).

Module summary¶
Functions
|
Estimate position errors as a function of time, assuming a certain error in atmospheric drag. |
|
Given pos vector, and pos vector at a small positive time offset, calculate unit vectors for along track, normal (towards center of Earth), and cross-track directions |
