Satellite and Integrated Space-Ground Network Emulation
From Orbital Links and Multi-Node Networks to Applications and Field Reproduction
Build repeatable labs across eight scenarios: orbital links, dynamic handovers, multiple terminals/gateways, space-ground integration, internet experience, equipment, DDIL and field reproduction, beyond a single fixed-delay link.

Why
Requirements
3GPP NTN covers communication nodes on satellites, HAPS and UAS. Orbits affect propagation delay, coverage, handovers and link budgets. Satellite applications serve remote areas, maritime/aviation, emergency command, energy sites and mobile terminals.
High-availability services face limited and uncontrolled satellite test resources. Labs must cover critical high-speed links, multiple terminals/gateways, satellite/5G/wired paths and real web/media/remote-work experience. Configure WAN emulators by node count, speed and ports.
NetAccura emulates end-to-end IP-link characteristics: delay, jitter, loss, bandwidth, reordering, outages, recovery, path changes and multi-node topology. It does not replace RF, orbital dynamics, beamforming, baseband or satellite protocol-stack simulation.

How
Implementation
2
Build Multi-Terminal, Gateway and Space-Ground Topologies
Connect satellite terminals, ground gateways, edge nodes, 5G and wired networks through multiple ports and independently configured links. Orchestrate scenarios to validate routing, redundancy and coordination.
3
Validate Satellite Internet Experience
Apply high delay, limited bandwidth, bursts and outages to web, apps, media, streaming, remote work and IoT. Save and reuse application impairment scenarios.
4
Validate Terminals, Modems and Gateways
Place VSAT, modem, CPE, ground gateways, TCP proxies, SD-WAN or security devices on controlled links. Run real voice, video, telemetry and transfers with background load to compare throughput, QoS, buffering, recovery and switching.
5
Bring Field Links into the Lab
Measure field delay, directional loss, jitter, micro-outages and throughput with BestPerf; retain sessions/PCAPs with Flow Hunter. Reproduce conditions and replay samples in the lab as regression cases.

Core Emulator and Supporting Tools
Core Emulation Equipment
Optional Supporting Tools
NetAccura Traffic Generation
NetAccura Traffic Generation
Generate L2-L3 test streams. Software models also replay Ethernet PCAPs, rewrite IPv4 addresses and TCP/UDP ports, and multiply traffic for performance, security detection and issue reproduction. Stop all transmit tasks before switching modes. Simultaneous generation and replay require separate devices.
Network Quality Measurement Software
BestPerf
Actively measure RTT, directional loss, jitter, micro-outages, TCP goodput and quality under load to establish link baselines.
Network Traffic Analyzer
Flow Hunter
Capture passively through mirrored ports or TAPs for L2-L7 analysis, session investigation, protocol-stage diagnosis and PCAP export.
Result
Expected Outcomes
Expand from Single Links to Complete Satellite Experiments
Cover GEO/MEO/LEO, multiple terminals/gateways, satellite/5G/wired paths, emergency communications and DDIL in one lab.
Configure Ports and Links for Your Topology
Use one WAN emulator family configured by speed, nodes and ports for single-link, multi-node and application impairment tests.
Reduce Field Satellite Trial Costs
Expose equipment, application, QoS and recovery issues in the lab, reserving limited satellite airtime for final confirmation.
Produce Reviewable Reports and Evidence
Deliver more than throughput or delay figures: include topology, parameters, timelines, quality curves, key sessions, anomalies, PCAP extracts and retest results. Development, testing, operations, vendors and customers can discuss the same evidence rather than relying on screenshots, verbal descriptions and repeated debate.
