2. Drone Dispatch Engine
Aeion compiles real flight missions and streams them to physical drones via Aeion Bridge.
Mission Configuration:
A mission is defined by a drone ID, a package ID, a destination (lat/lng/altitude), and an optional ordered list of intermediate waypoints (lat/lng/altitude).
Dispatch Pipeline:
- Mission Compilation: Aeion generates the flight mission as both a readable summary AND a real serialized MAVLink v2 binary
- Bridge Streaming: the mission is serialized to a genuine MAVLink v2 binary (real MISSION_COUNT + MISSION_ITEM_INT frames with a valid CRC) and uplinked via Bridge over 900MHz/2.4GHz radio to a connected Ground Control Station
- RTK GPS Telemetry: Real-time kinematic GPS returns high-accuracy position data
- Flight Status Tracking: Mission ID, estimated flight time, status updates
MAVLink Mission Protocol:
- Commands: NAV_WAYPOINT, NAV_TAKEOFF, NAV_LAND, DO_SET_SERVO
- Waypoint queue: List of GPS coordinates with altitude
- VTOL support: Vertical takeoff and landing for urban delivery
- Payload drop: Servo command at destination
Use Cases:
- Last-mile delivery in rural areas
- Medical supply delivery
- Food delivery in campus environments
- Emergency response supplies
3. Geofencing Engine
Aeion creates virtual boundaries and monitors entry/exit/dwell events against them.
Geofence Types:
- Circle: a center point (lat/lng) plus a radius in meters
- Polygon: an ordered array of lat/lng coordinates describing the boundary
Geofence Settings:
Each geofence can be enabled or disabled independently, and can be configured to trigger on entry, exit, and/or dwell — with a configurable dwell time (seconds inside the boundary before the dwell action fires).
Actions on Boundary Crossing:
- Alert — internal fleet alert
- Notification — push notification
- Webhook — HTTP webhook to your systems
- Task update — update a linked task's status
- Custom — custom handler
- Cyber-physical toggle — toggle a physical device
Geofence Events:
Every boundary crossing produces an event carrying the geofence, the entity (vehicle or driver), the event type (entry / exit / dwell), the location, and — for dwell events — how long the entity stayed inside.
Polygon Point-in-Geofence: A ray-casting algorithm determines whether a GPS point falls inside a polygon boundary.
4. Telematics Integration
Aeion integrates with GPS trackers, OBD-II devices, dash cameras, and ELD compliance devices.
Device Types & Providers:
Supported device types: OBD-II, GPS, dashcam, ELD, and custom. Supported providers: Geotab, Samsara, Verizon, and custom integrations. Every registered device reports a status (active / inactive / error / offline), a last-seen timestamp, and firmware version where available.
Telemetry Data:
Each telemetry record carries a timestamp plus, where available: location (lat/lng, accuracy, altitude, heading, speed), engine diagnostics (RPM, speed, fuel level, engine temperature, battery voltage, odometer, engine hours), fault codes (code, description, severity), and driver-behavior flags (harsh braking, harsh acceleration, harsh cornering, speeding, idling).
ELD Compliance (HOS Logs):
Each duty-status entry logs the status (off-duty / sleeper-berth / driving / on-duty), start and end time, duration, location, odometer, and engine hours — the full Hours-of-Service audit trail your DOT auditor needs.
5. Route Optimization Engine
Aeion solves the Vehicle Routing Problem (VRP) against real-world constraints.
Route Stop:
Each stop carries a location, a type (pickup / delivery / service), an optional time window, an expected duration at the stop, a priority, and optional requirements — required driver skills, required vehicle type, and payload capacity needed.
Optimization Constraints:
Routes respect max distance, max duration, max stops per route, vehicle capacity, driver shift-end time, toll avoidance, and whether to prioritize time over distance minimization.
Optimization Algorithm (Nearest Neighbor + 2-opt):
- Sort stops by priority and time windows
- Start with nearest stop to depot
- Greedily add nearest unvisited stop
- Apply 2-opt local search to improve route
- Calculate metrics: total distance, duration, cost
Optimized Route Output:
The result is an ordered stop list plus total distance (km), total duration (minutes), total cost (USD), an efficiency score (0-100), and estimated start/end timestamps.
6. Predictive Maintenance AI
Aeion uses AI to analyze vehicle data and predict maintenance needs before they become breakdowns.
AI Prediction Output:
Each prediction names the affected component (e.g. engine oil, brake pads, transmission), a predicted date, a confidence score (0-100), a severity (critical / high / medium / low), an estimated repair cost, a plain-language reason, and the specific telemetry indicators (value vs. threshold) that triggered it.
AI Pipeline:
- Gather: maintenance history, usage data, current diagnostics
- Build a structured request with the vehicle's data
- Send to your configured AI provider for analysis
- Parse the structured response (confidence, severity, indicators)
- Return the resulting maintenance predictions
Maintenance Schedule:
Each scheduled item carries a type (preventive / predictive / reactive), the component, a scheduled date, estimated duration and cost, a priority, and a status (pending / scheduled / in-progress / completed / cancelled).
