What

Adds carrier_doppler_pull_in_range(estimator, signal) — a doppler-estimator
interface function returning the maximum absolute carrier-Doppler error a
freshly-acquired satellite can carry and still be pulled into carrier lock.

A GNSS receiver can use it to choose the Doppler resolution for the Acquisition.

How

  • Interface: bare-stub forward declaration + docstring in sat_state.jl,
    beside init_estimator_state (the analogous mandatory per-estimator hook).
    Unimplemented estimators raise a MethodError, matching the existing
    convention.
  • ConventionalPLLAndDLL (FLL-assisted, the default): returns 1/(4·T),
    the range over which the FLL atan(cross/dot) discriminator is unambiguous
    (inter-prompt phase within ±π/2). → 250 Hz for GPS L1 C/A & L5I (T = 1 ms),
    62.5 Hz for Galileo E1B (T = 4 ms), 25 Hz for L1C-D/L1C-P (T = 10 ms).
  • ConventionalPLLAndDLL (pure PLL): returns the fast lock-in
    approximation min(B_L, 1/(2·T)) (Gardner/Best), B_L taken from the
    estimator config (auto-resolved via default_carrier_loop_filter_bandwidth
    when unset). Documented as an order-of-magnitude estimate, not a hard bound.
  • handover_coherent_integration_time(signal) helper in
    sample_parameters.jl, beside calc_num_code_blocks_to_integrate: derives
    the start-of-tracking integration time from the loop's own machinery
    (pre-sync, secondary_code_or_bit_found = false) rather than assuming a
    fixed length — so it tracks any change to the pre-sync integration policy.

The returned value is a hard ceiling (one-sided): an acquisition Doppler-bin
width of 2·range is the theoretical maximum, not a safe target — size narrower
for margin. Documented accordingly.

Notes

  • Zero-allocation and type-stable (verified); it's a cold-path query, never
    called inside track!.
  • Docs: new API entries + a "custom doppler estimator" guide section.

Testing

  • New tests in test/conventional_pll_and_dll.jl covering the FLL values, the
    pure-PLL approximation + bandwidth cap, and the required-interface MethodError.
  • Full test/runtests.jl passes locally (exit 0; Flexiband integration test
    skipped as usual — it needs the 1.6 GB capture download).

Benchmark Results (minimum time) — macos-14

Reporting the minimum over all samples (robust to shared-runner contention), not the median.

Alternative backends vs Float32 (track!, PR head)

Legend — backends: F32 Float32 (default) · I16 Int16 · 1b OneBit · 2b TwoBit (2-bit measurement + 2-bit carrier). Time columns are the minimum track! time; ×B = F32 / B (so >1 ⇒ backend B is faster than Float32), ✅ ≥ 5 % faster, ⚠️ ≥ 5 % slower. 1b/2b are BPSK-only, so their cells are blank for CBOC (Galileo E1B) scenarios.

feat(estimator): add carrier_doppler_pull_in_range interface
fba140b 
Add a required AbstractDopplerEstimator interface function reporting the
maximum acquisition carrier-Doppler error a freshly-acquired satellite can
carry and still be pulled into carrier lock. A GNSS receiver can use it to
pick the smallest satellite acquisition Doppler resolution needed to lock.

The integration length is derived from the loop's own
calc_num_code_blocks_to_integrate in the pre-sync state, so only the signal
is needed. ConventionalPLLAndDLL implements two methods:
- FLL-assisted: crisp 1/(4T) FLL-discriminator bound
- pure PLL: min(B_L, 1/(2T)) fast lock-in approximation

This feature can also be implemented directly in a GNSS receiver using Tracking.jl.
