Comparison between existing, well-established satellite technologies, like the Digital Video Broadcasting (DVB) satellite specifications, and the emerging Third Generation Partnership Project (3GPP) specified 5th Generation New Radio (5G NR) Non-Terrestrial Networks (NTN) is an actively discussed topic in the satellite industry standardization groups.
This article presents a thorough performance comparison between DVB Second Generation Satellite Extensions (DVBS2X) and Return Channel via Satellite 2nd Generation (DVBRCS2), and NR NTN in a Geostationary Orbit (GEO) satellite scenario, using system-level simulators (SLS) for evaluation, namely Satellite Network Simulator 3 (SNS3) and ALIX 5G (TN-)NTN SLS, built on the same Network Simulator 3 (ns-3) platform.

Tuomas Huikko, Verneri Rönty. “TN2: Simulation Report on Comparison of DVB-RCS2 and 3GPP NR NTN Technologies in LEO Systems.” April 2025.
This document contains a detailed description of the simulation- and simulator development work done for DVB project to compare the 5th Generation (5G) New Radio (NR) Non-terrestrial Networks (NTN) technology to Digital Video Broadcasting (DVB) Return Channel Satellite 2nd Generation (RCS2) in Low Earth Orbit (LEO) environments.
This comparison is a continuation of previous simulation work [1] and introduces new effects such as signal degradation from the Doppler shift and losses in gain when using Electronically Steered Antennas (ESA).
The main intent is to compare how the DVB-RCS2 technology performs vs. another major candidate for current and future satellite systems, namely 3rd Generation Partnership Project (3GPP) NR NTN. The comparison methodology is similar to previous comparison work in Geostationary Orbit (GEO) [2] satellite systems.
