P8800S UeSIM - Internal NTN Satellite Orbit Emulation Kickstart your non-terrestrial network testing 5G NTNs draw many features from 5G terrestrial networks and face many of the same challenges, adding higher service reliability expectations for 5G NTN service compared to earlier SATCOM networks. These challenges extend across physical, protocol, and application layers. They include emulating physical propagation conditions, such as large distances and speeds, compensation of delay and Doppler effect, and atmospheric / weather effects.
