- Coverage prediction heatmaps and per-satellite footprint polygons
- Synthetic, live TLE, fixed, and GEO/IGSO constellation sources
- Multibeam CINR analysis for GEO frequency-reuse payloads
NetSim Cyber
Cyberattack simulation for power and industrial networks
- Protocol-aware attacks across five grid protocols: synchrophasor, IEC 61850, Modbus, DNP3, IEC-104
- Attack catalogue: false data injection, replay, tampering, unauthorized control, and DoS
- Field-level mutation produces wire-valid packets, CRCs recalculated
- Runs as a software digital twin: safe, scalable, no hardware needed
- Measures the impact of an attack on grid operation
Connect to software simulators, HIL, or real devices
Choose the environment that matches the study. Run NetSim Cyber against its built-in software protocol simulators on a single machine, connect it to a hardware-in-the-loop (HIL) simulator, or wire it to a real device. The attacks stay the same; only the fidelity changes.
- Built-in protocol simulators: synchrophasor PMU, GOOSE/SV source, and Modbus and DNP3 masters generate original device traffic on a controlled LAN
- Interfaces with real devices: drives physical relays and IEDs, for example SEL and Siemens, over a live network
- Co-simulation with power-system tools: RTDS, OPAL-RT, Typhoon HIL, MATLAB/Simulink, OpenPMU, and openPDC
- Used by utilities and grid operators, SCADA and substation engineers, cybersecurity and defence teams, and universities
