}

Temporal correlation estimate used to deflate static PPP sample count.

The estimator pools lag-1 autocorrelation from standardized post-fit code and phase residual arcs, split by satellite and observable. It models the residual sequence as AR(1) in epoch units and converts the fitted lag-1 coefficient into an effective independent sample count. This captures short-memory temporal correlation such as multipath, residual troposphere, and orbit or clock interpolation errors that persist for minutes. It does not model spatially correlated or day-constant systematics, antenna effects, loading errors, or reference-frame errors.

Fields

lag1_autocorrelation: f64

Pooled nonnegative lag-1 autocorrelation coefficient.

decorrelation_time_epochs: f64

AR(1) decorrelation time in epoch spacings, computed as -1 / ln(rho).

decorrelation_time_s: Option<f64>

AR(1) decorrelation time in seconds when the input epochs have a regular positive spacing.

nominal_sample_count: usize

Number of residual samples contributing to the temporal estimate.

effective_sample_count: f64

Effective independent sample count after AR(1) deflation.

variance_inflation_factor: f64

Multiplier applied to covariance to account for temporal correlation.

arcs_used: usize

Number of satellite and observable arcs used in the pooled estimate.

Trait Implementations

impl Clone for TemporalCorrelationSummary

fn clone(&self) -> TemporalCorrelationSummary

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for TemporalCorrelationSummary

impl Debug for TemporalCorrelationSummary

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for TemporalCorrelationSummary

fn eq(&self, other: &TemporalCorrelationSummary) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
