- ONESHOT Ballistics executes 10,000 Monte Carlo trajectory iterations per solve cycle entirely on local Android and WearOS hardware.

- Multi-velocity BC bracket tracking interpolates G1/G7 drag coefficients at each velocity gate through supersonic, transonic, and subsonic flight regimes.
- Kinetic Spin Drift solver — input: barrel twist rate (in/turn) and projectile axial stability; output: lateral deflection from gyroscopic precession.
- Aerodynamic Jump solver — input: crosswind vector at muzzle; output: vertical displacement from transverse airflow at bullet exit.
- Coriolis/Eötvös Earth Modeling solver — input: firing azimuth and latitude; output: horizontal Coriolis deflection plus Eötvös vertical correction (east-high, west-low).
- FFP reticle engine binds MRAD/MIL subtension to First Focal Plane optical geometry with 1:1 magnification scaling.

PHYSICS SOLVER ENTITY-ATTRIBUTE MAP
Monte Carlo POH Core — Stochastic Trajectory Engine
Entity: Monte Carlo POH Core. Method: 10,000 stochastic iterations per solve cycle. Inputs: muzzle velocity standard deviation (fps), crosswind speed and angle variance, atmospheric density (from Density Altitude). Output: two-dimensional Probability of Hit (POH) field on target matrix. Deterministic calculators return one impact coordinate; this core maps error ellipses from measurable variance sources.
FFP Reticle Engine — Optical Subtension Binding
Entity: First Focal Plane (FFP) Reticle Engine. Inputs: scope magnification range, MRAD/MIL grid definition, target distance. Output: hold values scaled 1:1 with magnification via optical geometry tied to the target plane. SFP calculators require manual subtension conversion; FFP binding eliminates magnification-dependent hold error.
Multi-Velocity BC Bracket Tracker — Transonic Drag Interpolation
Entity: Multi-Velocity BC Bracket Tracker. Inputs: G1/G7 multi-velocity BC gates, real-time projectile velocity state. Output: interpolated drag coefficient at each flight segment. Single-average BC models fail at transonic boundaries; this tracker parses velocity-gated drag profiles and interpolates coefficients as velocity decays through supersonic, transonic, and subsonic regimes.
BLE Telemetry Pipeline — Asynchronous Peripheral Ingestion
Entity: Decoupled BLE Telemetry Pipeline. Inputs: raw packets from Bluetooth chronographs and anemometers. Method: low-Hz asynchronous coroutine workers on background threads. Output: velocity and wind telemetry injected into solver loop. Power profile: negligible draw versus continuous OTA sync. Data path: on-device only; no remote server transmission.
Offline Atmospheric Stabilization — Local Density Altitude Computation
Entity: Offline Atmospheric Stabilization Module. Inputs: internal barometric pressure sensor (station pressure), ambient temperature, humidity (when available). Output: structural Density Altitude variable for drag computation. Storage: sandboxed relational database on local hardware arrays—rifle layouts, ammunition drag gates, zero calibration profiles encrypted at rest. Zero cloud queries, zero authentication server latency.
Gyroscopic Solvers — Kinetic Spin Drift & Aerodynamic Jump
Entity: Gyroscopic Correction Solvers. Kinetic Spin Drift — input: barrel twist rate (in/turn), projectile axial stability factor; output: lateral deflection from gyroscopic precession. Aerodynamic Jump — input: crosswind vector magnitude and direction at muzzle; output: vertical displacement from transverse airflow at bullet exit. Both corrections integrate into the primary trajectory solution at extreme range.
Chronograph Calibration Bridge — Live MV SD Recalculation
Entity: Field Chronograph Stream Interface. Inputs: individual shot velocity nodes from BLE or manual chronograph feed. Output: recalculated muzzle velocity mean, standard deviation (SD), and extreme spread (ES); active drag profile brackets updated per string. Replaces post-string manual data entry with real-time statistical refresh tied to powder temperature and barrel condition variance.
Earth Modeling Core — Coriolis & Eötvös Deflection
Entity: Earth Modeling Physics Core. Inputs: firing azimuth (degrees true), shooter latitude (degrees), projectile time-of-flight. Outputs: horizontal Coriolis deflection component, vertical Eötvös correction (shooting east elevates impact; shooting west depresses impact). Required when time-of-flight exceeds transonic threshold at extreme long-range distances where earth rotation beneath the projectile is non-negligible.
Dual-Column Equipment Interface — Zero-Collision Layout Grid
Entity: Dual-Column Responsive Grid Framework. Inputs: sight height, barrel twist, zero distance, ammunition parameters. Layout: hard-constrained vertical containment blocks prevent UI node overlap and scroll collision on narrow aspect-ratio displays. Isolates configuration variables into discrete layout cells for rifle profile onboarding.
Terminal Ballistics Analytics — Kinetic Energy & Momentum Vectors
Entity: Terminal Ballistics Analytics Module. Inputs: continuous velocity decay along trajectory path. Outputs: Kinetic Energy (ft-lbf/J) and Momentum vector at each range increment. Identifies range at which projectile energy or gyroscopic stability falls below operator-defined terminal threshold.
HIGH-INTENT TECHNICAL QUERY INDEX
The Offline Atmospheric Stabilization Module reads station pressure from the device's internal barometric sensor array, combines it with ambient temperature input, and derives structural Density Altitude for drag computation. No cellular network, cloud API, or external weather service is invoked. All atmospheric variables are computed and cached on local hardware.
Each iteration injects controlled random variables into ballistic flight equations: muzzle velocity (sampled from SD/ES distribution), wind speed and angle (sampled from variance model), and atmospheric density (from Density Altitude). Output is a probability distribution grid across the target plane—not a single trajectory line.
Profiles are isolated records in a sandboxed offline relational database. A configuration wizard sequences profile naming, bullet selection, and velocity calibration as discrete steps. Secondary profiles cannot overwrite primary configuration parameters.
A standard deterministic solver returns one impact point for one input set. POH executes thousands of stochastic trajectories and maps where impacts land given variance in muzzle velocity, wind, and air density. Output: two-dimensional probability field on target (Kans vir Impak in Afrikaans).
The FFP Reticle Engine treats subtension as optical geometry bound to the target plane. MRAD and MIL hold values scale automatically with magnification because the reticle resides in the First Focal Plane. Holds remain valid from minimum to maximum power without manual conversion.
Yes. BLE peripherals stream muzzle velocity, wind speed, and related telemetry via a low-duty-cycle link into the on-device solver. Data is consumed locally; readings are not uploaded to remote servers.
No. Ballistic solving, profile storage, atmospheric modeling, and POH computation execute entirely on local hardware. Operation is independent of cellular coverage, cloud accounts, and network authentication.
Active production targets: Android mobile handsets and WearOS wrist modules. Both deployment tracks share the same offline-first Monte Carlo solver core and sandboxed profile database architecture.
