Onyx — Cloud Fleet
Management Wired
to the Hardware.

A cloud fleet management platform that streams telemetry from Teltonika GPS hardware at 2.4 updates/sec with ±3m accuracy — live map, geofencing, trip playback, and sub-200ms alerting, multi-tenant from day one.

The case

One live map. Every vehicle. Every moment.

The problem

UAE logistics operators run on a patchwork of tools. Dispatchers decide with stale data. Drivers aren't held accountable without replayable evidence. Simple questions become hunting expeditions.

  • One system for GPS, another for maintenance, Excel for fuel
  • No replayable evidence of harsh braking or route deviations
  • "Where was vehicle X at 14:22 last Tuesday?" — unanswerable
  • Per-vehicle licensing tracked in spreadsheets

The solution

Onyx consolidates the entire fleet stack onto one live platform wired to the hardware — no middleware, no polling, just raw Codec 8 streams into a real-time map.

  • Teltonika FMB920/FMC130 → TCP → live Mapbox map
  • Four geofence types: STAY-IN · STAY-OUT · CORRIDOR · CHECKPOINT
  • Trip playback at 1× / 2× / 4× / 8× with every event visible
  • Multi-tenant: companies → branches → projects, RBAC throughout
Hardware integration

From CAN bus to map pin.

Raw bytes off the vehicle into a rendered pin on the dispatcher's screen. Here's how the signal travels — every hop instrumented, every byte accounted for.

Capability

Six pillars.

01 /
◉

Real-Time Tracking

Mapbox-powered live map. Clustered at altitude, individual up close. Pins update 2.4× per second per vehicle.

02 /
⬚

Geofencing

Four types: STAY-IN, STAY-OUT, CORRIDOR, CHECKPOINT. Drawn directly on the map. Alert-on-cross in under 200ms.

03 /
▶

Trip Playback

Every trip stored forever. Scrub the timeline at 1× / 2× / 4× / 8×. Harsh events marked as waypoints.

04 /
⚡

Smart Alerts

Speed, harsh braking, geofence breach, idle, ignition, low fuel. Pushed via email, SMS, WhatsApp, in-app.

05 /
⛽

Maintenance & Fuel

CAN-bus fuel consumption. Service schedules by mileage or hours. Automatic work-order generation.

06 /
⌘

Multi-Tenant

Companies → branches → projects. Admin, manager, operator, driver, view-only roles. License-managed.
