Square Peg Communications, a leader in satellite systems engineering and DSP-based satellite communication products, is enabling high-performance testing for MilSat communications through its advanced Radio Link simulator. The RLS-2100 enables users to model, simulate, and optimize mission-critical satellite links across a broad frequency range. In hostile environments, where failure is not an option and every advantage counts, Square Peg’s expertise in advanced satcom solutions, combined with the RLS-2100’s high-performance testing capabilities, ensures total effectiveness amid rapidly evolving space-based communications. The RLS-2100 is an ideal testing solution for MilSat networks, ensuring satellite communication systems are fully prepared to handle a wide range of threats before they are encountered in the field.
The RLS-2100 is a dedicated solution for testing and optimizing military satellite networks, supporting constellations across all orbits and frequencies from L-band to V-band with multi-beam, multi-terminal capabilities. Designed for high-accuracy scenario modeling, it allows users to simulate and evaluate complex threats before deployment. With the intuitive setup and rapid adjustments, the RLS-2100 helps maximize testing efficiency and mission preparedness. This Radio Link Simulator from Square Peg Communications operates with a standard frequency of 700 to 2150 MHz (independent I/O) and offers optional internal 5G FR1 (400–7125 MHz) and external 5G FR2 (10.7–31 GHz) support. The RLS-2100 enables militaries to simulate and test complex scenarios, helping them prepare for and overcome threats to network availability and performance. As satellite communications rapidly evolve with new generations of LEO, MEO and multi-orbit constellations, staying ahead of change is essential. The ability to model real-world conditions in the lab helps mitigate the unpredictability of conflict, ensuring that communication systems function reliably in any environment. With growing risks from electronic warfare and infrastructure attacks, the RLS-2100 supports the development of resilient systems, maximizing readiness and enabling forces to face the unexpected with confidence. It offers seamless integration with GPS, OpenAMIP, or ARINC 429 interfaces for synchronization of devices under test with the simulation, and a Python-based remote control API for easy automation.
The RLS-2100 is a versatile and comprehensive tester, delivering fast and repeatable results, making it the ideal choice for:
- Upgrading test beds for wideband signal compatibility
- Verifying link budgets with true hardware-in-the-loop testing
- Testing modem performance under dynamic link conditions
- Verifying new satellite network configurations
- Proving and refining next-generation satellite network concepts before deployment
Capabilities of RLS-2100 include:
Simulate missions: It can set up new scenarios in minutes with its intuitive interface and all-in-one tester, simulate satellite links under realistic conditions with the physical equipment at RF, and recreate the most demanding conditions that communication systems may face to ensure preparedness.
Test the latest gear: Some things you can test include new waveforms, new modems, impacts of varying antenna characteristics, operation of existing equipment and applications over new types of satcom links, and proof of concepts.
Prepare for conflict zones: The RLS-2100 enables comprehensive, physically accurate testing to ensure readiness in the most challenging environments. Simulating real-world impairments, such as location-specific atmospheric conditions, multi-path reflections, and low-elevation antenna angles, allows you to validate performance and reliability before entering conflict zones.
With capabilities to simulate complex mission scenarios, test new waveforms and equipment, and model real-world impairments like multipath and low elevation angles, the RLS-2100 helps ensure network readiness in unpredictable and hostile environments. Its user-friendly interface enables rapid setup and accurate testing, making it a vital tool for strategic communications preparedness.
