Square Peg Communications has added software enhancements to the company’s RLS-2100 Radio Link Simulator—the simulator will be the first to enable up to 2 GHz bandwidth in a single compact solution for ultra-wide bandwidth hardware-in-the-loop testing and will also allow satellite operators, manufacturers and integrators and defense agencies to conduct dynamic and precise 5G non-terrestrial network (NTN) testing of new use cases, and enable seamless OpenAMIP modem to antenna integration.
The three new features will ensure satellite communications operators are able to test and simulate their systems for reliability and resiliency under the most demanding conditions prior to deployment. They include:
2 GHz Bandwidth Support for Ultra-Wideband Testing
The RLS-2100 is the only platform offering 2 GHz bandwidth in a single compact device, enabling ultra-wideband RF testing. The added bandwidth is significant as data throughput demands increase, particularly in defense communications, Earth observation and other satellite applications. This capability enables military and government customers, with access to wide spectrum resources, and commercial LEO satellite operators to consolidate multiple carriers for greater efficiency and cost-reduction. Operators and integrators have the flexibility to add extra bandwidth or channels to the “future-ready” RLS-2100 later to test emerging ultra-wideband applications—delivering higher throughput, faster downloads and unmatched performance when needed.
Dynamic 5G NTN Testing to Synchronize Satellite Movement and Networks
A new real-time satellite ephemeris streaming feature enables operators to use the RLS-2100 to accurately test real-time 5G NTN satellite positions and to set up fully synchronized scenarios to relay data to user terminals through 5G protocol messages. This synchronized test platform enables critical verification of low-latency, high-speed connections in 5G systems. Square Peg pioneered this technology when it was previously selected by the European Space Agency (ESA) to develop an emulation environment for testing scenarios across multiple satellite constellations as part of its Space for 5G and 6G Strategic Program Line. In partnership with WORK Microwave, and with support from the Canadian Space Agency and ESA, Square Peg delivered a solution that models dynamics, controls channel impairments, and spans nearly 30 GHz, meeting ESA’s advanced requirements.
OpenAMIP Integration for Realistic Antenna Control Simulation
Square Peg’s RLS-2100 is also the first platform to offer fully-integrated OpenAMIP simulation, making testing in the lab as realistic as field conditions. Modern satellite systems rely on dynamic antenna adjustments, especially in mobile and maritime satellite networks. OpenAMIP integration lets satellite operators needing realistic test scenarios easily simulate these real-world antenna behaviors in a lab to avoid expensive failures in the field, while minimizing test setup complexity and facilitating optimal use of channel emulation resources.
“As satellite communications advances and continues to require higher bandwidth for an increasingly data-driven future, it also increases the complexity of testing and simulation prior to launching into orbit,” said Michael Gertsman, president, Square Peg Communications. “Square Peg is leading the way with the RLS-2100 platform, adding breakthrough capabilities to meet the increased need for greater bandwidth, robust 5G NTN satellite communications testing and OpenAMIP integration for realistic simulation of antenna control — all from a single compact and cost-effective box.”
Square Peg Communications will showcase this technology at booth #1214 at the SATELLITE 2025, March 10-13.
