Total Visibility. Real-Time Intelligence
SIMAC: The Pulse of Your Fleet
Stop guessing and start governing. SIMAC is Nerospec’s premier Fleet Data Monitoring (FDM) solution, designed to transform raw machine telemetry into actionable operational excellence. Whether it’s surface or underground, SIMAC bridges the gap between your machines and your decisions.
What is Fleet Data Monitoring?
Why Fleet Data Monitoring?
FDM is the continuous process of capturing, transmitting, and analyzing high-fidelity data from mobile assets. By integrating sensors, location data, and onboard controllers, SIMAC transforms raw machine activity into a centralized stream of intelligence.
The Core Philosophy:
You can't manage what you don’t measure
The Power of simac
Operational Performace
Tracking "Short Interval" metrics: idle time vs. tramming time, bucket load weights, and trip counts.
Safety & Compliance
Recording overspeed events, geofence breaches, and Proximity Detection (PDS) "crawl" or "stop" interventions.
Production & Maintenance Intelligence
Production Intelligence: Turning Motion into Metric
SIMAC provides high-fidelity visibility into your production cycle, allowing you to eliminate bottlenecks in real-time. By monitoring the “heartbeat” of your machines, we ensure every shift reaches its maximum potential.
FROM FLEET DATA TO OPERATIONAL CLARITY
Production Insights
Short Interval Control (SIC)
Don’t wait for the end-of-shift report to find out you missed targets. Track production KPIs, including accurate payload monitoring (bucket-by-bucket) to prevent under or over-loading. SIMAC provides high-fidelity visibility into your production cycle, allowing you to eliminate bottlenecks in real-time. By monitoring the “heartbeat” of your machines, we ensure every shift reaches its maximum potential.
Cycle Time Analysis
Granular breakdown of spotting, loading, hauling, and dumping times to identify inefficiencies
Fuel & Energy Efficiency
Pinpoint exactly where and why machines are idling and correlate fuel burn with operator technique.
Technical Deep-Dive & Hardware
Technical Overview: Data Integrity in the Field
- Ruggedized Hardware: Featuring the neroHUB, nanHUB and neroMARSHALL and our hardware is built to survive the harshest industrial environments on earth.
- Store-and-Forward Capabilities: Data you can trust, even when the network drops. If a machine moves out of Wi-Fi coverage, it logs every data point and “burst-uploads” the moment it connects to another vehicle or a hotspot.
Empower Your Workforce with a Shared Database
Automated monitoring prevents overreporting by third-party contractors by independently verifying trip data, ensuring a fair and shared database for mining operations and contracting companies alike.
Fleetwide visibility from sensor to dashboard
Capture, transfer, and visualize critical machine data across underground fleets — without relying on full mine-wide network coverage.
Data Capture
Collect critical machine data directly from underground equipment using compact, purpose-built hardware.
Data Forwarding
Transfer data across the mine through nearby fleet vehicles, even where full network coverage is limited.
Real-Time Insight
Visualize machine health and performance in live dashboards, with straightforward integration into existing mine information systems.
Proven Implementation & Success Stories
Our Implementation of Fleet Data Monitoring
Over the years, Nerospec SK has successfully implemented fleet data monitoring solutions across underground mining operations, helping sites improve visibility, operational efficiency, and equipment reliability through real-time data intelligence.
SIMAC enables mines to collect, centralize, and analyze critical fleet data from across their mobile equipment, transforming raw machine information into actionable insights for maintenance planning, production optimization, and performance management.
By delivering continuous visibility into machine health, operational behaviour, and production metrics, fleet data monitoring empowers mining teams to make faster decisions, improve asset utilization, and maintain tighter control over day-to-day operations.

FAQ
What matters most, answered clearly
What data can SIMAC capture from underground equipment?
SIMAC captures a wide range of machine and operational data, including engine parameters, payload, cycle times, idle time, fuel consumption, location data, and safety events. It integrates signals from onboard systems, sensors, and third-party devices to provide a comprehensive view of fleet performance.
Can SIMAC work with mixed fleets and different OEMs?
Yes. SIMAC is designed as an OEM-agnostic solution, enabling data collection and monitoring across mixed fleets. It can be deployed on equipment from multiple manufacturers, regardless of machine age or existing onboard systems.
Does SIMAC require continuous network connectivity to operate?
No. SIMAC is built for underground environments where connectivity is often limited. With store-and-forward capabilities, data is buffered locally and automatically transmitted once the system reconnects to the network, ensuring no data is lost.
How does SIMAC support Short Interval Control (SIC)?
SIMAC provides real-time and near-real-time operational data, allowing supervisors to monitor performance, identify deviations, and take corrective actions during the shift. This enables more effective Short Interval Control and improves decision-making at all operational levels.
Can SIMAC be used for predictive or condition-based maintenance?
Yes. By continuously monitoring machine health indicators such as engine load, temperature, and usage patterns, SIMAC supports condition-based maintenance strategies. This helps detect potential issues early and reduces unplanned downtime.
How does SIMAC improve production performance?
SIMAC transforms raw machine data into actionable insights, enabling operators and supervisors to identify bottlenecks, optimize cycle times, and improve equipment utilization. This leads to increased productivity and more consistent output.
Is SIMAC compatible with existing mine management systems?
Yes. SIMAC is designed for integration and can connect with existing mine management, dispatch, and reporting systems through APIs and standard data interfaces, enabling seamless data exchange across platforms.
How is data accuracy ensured in harsh underground conditions?
SIMAC relies on ruggedized hardware designed for extreme environments, combined with edge processing and validated data acquisition methods. This ensures reliable and high-integrity data, even in challenging underground conditions.
