Challenge of Satellite Networks: Atmospheric Interference and Varying Distances

Satellite networks, including the emerging Starlink (LEO) and other constellations, pose unique challenges for applications compared to traditional WANs or Mobile Networks. With varying wavebands (L, S, C, X, Ku, K, Ka, etc.), signals must traverse the atmosphere, covering distances from approximately 1,200 miles or 2,000 km for LEO satellites to as far as 22,236 miles or 35,786 km each way for GEO satellites. These extensive distances expose applications to factors like moisture-laden atmospheres and potential interference.

This “Stress” Results In:

Application Performance Issues

Slow Response Times

Timeout Failures

Satellite Network Emulation: Producing Realistic Conditions for Effective Application Testing and Issue Resolution

With the use of Calnex Network Emulators, satellite network conditions can be accurately replicated without the need for actual satellites, terminals, or satsims. Allowing for comprehensive testing of applications under simulated satellite conditions, enabling the easy and cost-effective identification and resolution of potential issues before customer delivery. 

By recreating the unique challenges posed by satellite networks, our solution enables comprehensive testing in a controlled and repeatable test environment without need for renting satellite time.

Calnex Network Emulators create test networks with characteristics that cause applications issues in VSAT, LEO, MEO and GEO satellite networks and are easily adjustable to mimic different satellite services like Inmarsat Global Xpress (GX), different technologies like VSAT, as well as different satellite orbits like GEO, MEO and LEO and control of different loading, congestion and conditions.
