Module sidereal 

Repeating-geometry residual filtering.

This module is a pure post-processing kernel for residual arrays. It models local-environment repeat signatures as a phase-stacked template at a supplied repeat period, then subtracts only corrections backed by the requested prior coverage.

Structs

SiderealFilterOptions

Options controlling residual template stacking.

SiderealFilterOutput

Output of sidereal_filter.

Enums

SiderealFilterError

Errors returned by sidereal filtering and repeat-period helpers.

SiderealTemplateMethod

Template estimator used by sidereal_filter.

Constants

SIDEREAL_DAY_NANOS

Length of the mean sidereal day used for constellation-default GPS phasing.

SIDEREAL_DAY_SECONDS

Length of the mean sidereal day in SI seconds.

Functions

orbit_repeat_lag

Compute a per-satellite orbital repeat lag from a broadcast ephemeris.

periodicity_strength

Score repeating components at candidate periods for 1 Hz samples.

periodicity_strength_with_sample_interval

Score repeating components at candidate periods for an explicit cadence.

repeat_period

Return the default ground-track repeat period for a GNSS constellation.

sidereal_filter

Remove a repeating residual component by phase-stacking prior repeats.

solar_day_period

Return the 24-hour solar day as a duration for diagnostic callers.
