Satellite & NTN Resources
Worked studies, documentation, and comparisons for satellite and 5G non-terrestrial network simulation: link budgets, the 3GPP TR 38.821 reference scenario, in-flight connectivity, and RF coverage planning.
Worked studies
Complete scenarios with parameters, results, and discussion.
System-level study
3GPP TR 38.821 reference scenario →
The six reference scenarios explained, and the Set-1 LEO-600
S-band scenario simulated: SINR, throughput, and capacity metrics.
Application study
In-flight connectivity over LEO →
A Bangalore to Delhi flight over 50 and 100 LEO satellites:
satellite handover, throughput, SINR, and availability.

step.
Comparisons and Q&A
How the tools compare, and detailed answers on scope and modelling.
Comparison
Astra vs STK vs MATLAB →
Satellite coverage tools compared for the RF planning
workflow, and where each tool wins.
Q&A
NetSim NTN Q&A →
21 questions on orbits, beams, link budgets, scheduling under
satellite delay, and what is not modelled.
Q&A
NetSim Astra Q&A →
24 questions on the coverage-planning workflow, sourced
against STK and MATLAB documentation.
