Square Peg Communications, a global leader in SATCOM test and simulation solutions, is at the forefront of enabling the industry’s shift toward multi-orbit connectivity. With more than three decades of expertise, the company is helping operators, defense organizations, and enterprise customers validate and deploy resilient multi-orbit networks that combine the strengths of geostationary (GEO), medium Earth orbit (MEO), and low Earth orbit (LEO) systems.
The satellite communications industry is undergoing a profound shift, moving away from reliance on single-orbit systems to embrace multi-orbit architectures that combine GEO, MEO, and LEO satellites. This transition is redefining connectivity for commercial, defense, and enterprise customers alike.
The growing adoption of multi-orbit networks is being driven by the limitations of single-orbit models, which are more vulnerable to outages, coverage gaps, and interference. By blending the strengths of multiple orbits, operators can achieve higher resilience, greater coverage, and improved performance across a wide range of applications—from secure backhaul to real-time, low-latency communications.
Each orbit has distinct advantages: GEO satellites deliver broad coverage; LEO networks support high-bandwidth, low-latency services; and MEO satellites strike a balance between the two. Together, they enable seamless connectivity, continuous service, and even redundancy for positioning, navigation, and timing (PNT) systems in the event of disruption or jamming.
While the promise of multi-orbit connectivity is clear, success depends on rigorous testing and validation. Advanced engineering is required to integrate multi-link terminals, manage complex ground segments, and ensure smooth handovers between orbits. Hardware-in-the-loop (HIL) testing, in particular, plays a critical role in guaranteeing reliability, resilience, and interoperability before deployment.
The RLS-2100 Radio Link Simulator from Square Peg Communications supports real-time multi-orbit satellite network simulations, including GEO, HEO, MEO, and LEO constellations or any combination thereof. It integrates detailed channel modeling to apply orbit-specific effects such as Doppler shift, path loss, and delay, along with antenna modeling for accurate simulation of various beam types.
The system enables verification of link performance and handovers across LEO-LEO, LEO-GEO, and GEO-GEO connections, ensuring reliable end-to-end testing. It also evaluates application performance as networks adapt to changing latency, capacity, and link conditions across multiple orbits.
With over 30 years of SATCOM expertise, Square Peg is committed to helping the industry realize the full potential of multi-orbit networks. Their test and simulation solutions are designed to ensure that hybrid architectures deliver the performance and reliability that operators and their customers demand.By supporting the development and validation of these next-generation systems, Square Peg Communications is helping turn the vision of adaptive, resilient, multi-orbit SATCOM into an operational reality.
