Enums§

RefineMode
Refinement mode, AOS or LOS
StepPassDirection
Pass stepping direction used for pass stepping function below.

Functions§

calculate_user_posvel
passes the user’s geodetic position and the time of interest and returns the ECI position and velocity of the observer
elevation_derivative
Convenience function for calculation of derivative of elevation at specific time.
find_max_elevation
Find maximum elevation bracketed by input lower and upper time.
get_passes
Errors
observer_calculate
The procedures observer_calculate calculates
predict_next_aos
Errors
predict_next_los
Errors
predict_observe_orbit
Calculates range, azimuth, elevation and relative velocity from the given observer position. and whether orbit is visible if sun elevation is low enough and the orbit is above the horizon, but still in sunlight.
refine_obs_elevation
Errors
step_pass
Rough stepping through a pass. Uses weird time steps from Predict.
