Inertial navigation system. Tightly coupled GNSS + accelerometer + gyroscope fusion.

Digital and analog IO service. Levels, transitions, and PWM exposed as signals.

Kiosk orchestration micro service. Coordinates LLM, RAG, MCP, and voice pipeline for voice-first Q&A with a per-answer audit manifest on the EventBus.

LiDAR capture and frame normalisation for autonomy and ADAS pipelines.

On-device small language model service with quantized inference, EventBus token-stream topic, refuse-preferred system prompt, and opt-in cloud fallback under tight controls.

Distributed log synchronisation, archiving, and remote logfetch over MessageGate.

Model Context Protocol server with declarative tool allow-list. Last-line-of-defence in the four-layer prompt-injection defence chain; gates network capability for opt-in cloud fallback.

Event processor. Trigger → condition → action rules in YAML, evaluated against MOS4 DB changes, schedules, and live events.

Cellular modem service. Multi-SIM, signal-aware roaming, MD21-aware payload shaping for constrained plans.

Embedded MQTT broker. Bridges any standard MQTT client to MOS4 services via JSON or protobuf.

Multi-signal processing engine. Compose CAN, sensor, and event streams as a typed graph; deploy from a YAML manifest.

Vehicle communication engine. CAN, CAN-FD, J1939, J1850, HD-OBD, DoIP, and OEM-private PIDs decoded with one runtime.

Prometheus + OpenTelemetry exposure across every microservice; fleet-wide dashboards.

OTA firmware updates over MD21 or service call. A/B partitions, signed packages, automatic rollback.
