Struct Timeouts 

pub struct Timeouts {
    pub dead_reckoning_after: Seconds,
}

How long the filter may go without horizontal aiding before the status reports it dead-reckoning.

What the status says; what the filter does about a source it keeps rejecting is Recovery’s. When a single source counts as timed out is not configured: each source’s own measured period sets it, SourceHealth::timeout.

Fields

dead_reckoning_after: Seconds

Beyond this with neither GNSS position nor GNSS velocity accepted, the status becomes DeadReckoning, whatever else is still arriving. Also a source’s timeout until its period is measured.

Horizontal, because that is the error nothing else bounds: a barometer holds height and a magnetometer heading, and position still drifts. PX4’s inertial_dead_reckoning is the same test (src/modules/ekf2/EKF/ekf_helper.cpp:804-903 at c4e4ef98e9), cleared only by horizontal position or velocity aiding, and ArduPilot’s dead_reckoning flag reads horizontal sources alone (libraries/AP_NavEKF3/AP_NavEKF3_Control.cpp:811 at 368dc0c428). A mission question rather than a measured one: how long a vehicle may navigate on its inertial solution is what it is flying for.
