A satellite network operator needs to model the performance of their network before expanding an existing GEO network to include LEO satellites. 

Using RLS-2100, they are able to:

• Use real hardware to verify the impact of adding LEO satellites to their existing GEO network to extend coverage and increase capacity
• Use integrated modeling of a multi-orbit satellite network to apply varying channel characteristics, including Doppler and dynamic path loss/delay
• Use integrated antenna modeling capabilities to enable realistic simulation of satellite beams of various types
• Verify link performance across the multi-orbit network, including LEO-LEO, LEO-GEO and GEO-GEO beam and satellite handovers
• Verify seamless operation of applications over each satellite constellation and manage the user experience as the network adapts to changing latency, capacity and link conditions

A provider of air traffic control safety services needs to ensure that the performance of their service would not be compromised if Ka-band feeder links were employed.

Using RLS-2100, they are able to:

• Have Square Peg’s team create a test bed based on the radio link simulator that can realistically model their link conditions and mitigation mechanisms, such as uplink power control and site diversity
• Have key satellite propagation characteristics imparted onto the radio link signals passing through it
  • Including rain fading events based on ITU models, Doppler, delay, AWGN, phase noise, interference, multipath fading and more
  • Applicable link conditions fully synchronized between channels
• Allow the test bed controller to remotely simulate satellite ALC and Uplink Power Control algorithms that automatically adjust signal levels during tests, and to simulate the decision logic used to control site switching
• Adjust the parameters of their power control and site switching algorithms to minimize the effects of rain fade on end-to-end safety service performance — and demonstrate to customers that the required service availability can be achieved

An in-flight connectivity provider needs to ensure gate-to-gate reliability by recreating complex on-air scenarios before flying.

Using RLS-2100, they are able to:

• Verify performance before rolling out new satellite-based services that use a variety of satellite types with different characteristics
• Ensure seamless connectivity by verifying that the satcom selects the appropriate satellite in all scenarios and hands over between beams and satellites reliably and with minimal service impact — while recovering from temporary outages caused by loss of coverage or aircraft maneuvering
• Use integrated modeling of stations in motion, including satellite constellations and aircraft in flight, to create realistic route simulations
• Use the integrated antenna modeling capability to account for realistic antenna gain vs. azimuth and elevation, including keyhole effects caused by the aircraft’s tail
• Use the ARINC 429 interface to provide the airborne satcom with position information fully synchronized with the test scenario
• Improve the robustness of their solution in off-nominal cases such as when signal lost due to aircraft maneuvers during handovers
• Bring their link into the lab to provide significant cost savings vs. running flight trials —while gaining the ability to explore conditions not readily reproduced in a limited number of flight trials

A 5G operator needs to test how satellite links would behave in their new hybrid network.

Using RLS-2100, they are able to:

• Simulate terminal link handovers between their terrestrial and satellite networks
• Use integrated scenario modeling to apply realistic link characteristics for the terminal and satellites in motion
• Identify issues related to maintaining seamless connectivity across handovers due to varying link characteristics and adjust network operation to compensate
• Verify their network performance to reduce risk moving forward
