+
+Библиотека расчета программ управления угловым движением КА.
+
+Библиотека создана как перенос расчетного контура из проекта `OrbitalMotion/AISTPUUD/SurveyPUUD`:
+
+- `ConstOrientAISTPUUD` → `ConstOrientPUUD`;
+- `AzimuthAISTPUUD` → `AzimuthPUUD`;
+- `SmoothSDIAISTPUUD` → `SmoothSDIPUUD`.
+
+В новых классах нет префикса `AIST`. Вместо старого C++/Qt `Ballistics` используется существующая Kotlin-библиотека проекта PCP:
+
+- `ballistics.orbitalPoints.timeStepper.AbstractStepper` для выхода на заданное время;
+- `ballistics.types.OrbitalPoint`, `Orientation`, `BLHPoint`;
+- `ballistics.utils.astro.AstronomerJ2000`;
+- `ballistics.utils.math.Vector3D`, `Matrix3D`, `Quaternion3D`.
+
+Основной API:
+
+```kotlin
+val calculator = AngularMotionCalculatorFactory.create(
+    mode = AngularMotionMode.AZIMUTH,
+    stepper = stepper,
+)
+
+val result = calculator.calculate(
+    SurveyId(
+        nlv = 4,
+        t = startTimeSeconds,
+        b = latitudeRad,
+        l = longitudeRad,
+        h = heightMeters,
+        duration = 20.0,
+        sdi = listOf(150.0),
+        azimuth = azimuthRad,
+    )
+)
+```
+
+## Примечания по переносу
+
+1. Временные параметры задаются в интегральных секундах, как в `ballistics-lib`.
+2. Углы задаются в радианах.
+3. Линейные параметры оптики в `AngularMotionConfig` сохранены в миллиметрах, как в исходном `sBLS_KA`.
+4. Расчет времени начала режима сохраняет подход `calcTn`: поиск корня на интервале `t ± 180 с` и округление к `discreteTimes`.
+5. Интервал успокоения рассчитывается обратной интерполяцией первых точек ПУУД, аналогично `TauIntervalCalculator`.
