Arguments

data

A dataframe or similar which has previously been cleaned.
x

The name of the X coordinate column.
y

The name of the Y coordinate column.
time

The name of the timestamp column.
point_angle_cutoff

The turning angle (in degrees) above which high instantaneous speeds are considered an anomaly rather than fast transit.
reflection_speed_cutoff

The speed (in m/s) above which an anomaly is detected when combined with a high turning angle.
est_ref_len

The maximum number of positions to search after the anchor for a potential reflection end.

Value

A dataframe with reflections removed.
