4th generation satellite waveform from NovelSat
NovelSat NS4 is the satellite industry’s newest 4th generation transmission waveform. Already, NovelSat NS4 is the waveform of choice for broadcasters and data networks around the globe. As worldwide demand for data and content continues to grow rapidly, the need for even more bandwidth-efficient satellite transmission solutions is ideally addressed by NovelSat NS4.
Satellite transmission has gone through many changes. The constant need for higher data rates and improved efficiency led to a standards evolution race DVB-S ⇒ DVB-DSNG ⇒ DVB-S2 ⇒ DVB-S2X ⇒ NovelSat NS3…
The challenge is the complexity of the migration process. Most satellite transmission equipment is based on rigid architecture (chipset), leading to substantial investment in hardware replacement and service interruption. Therefore, the majority of satellite links continue to operate with old technology.
This challenge led NovelSat to develop a software-defined architecture that is at the core of the NovelSat NS4 waveform. Both are based on high performance DSP/FPGA which make it possible to perform maintenance, add features and even upgrade to the newest waveform remotely Over-the-Air – using existing satellite bandwidth.
NovelSat NS4 Enhancements
As the next generation successor to NovelSat NS3, the industry’s spectral efficiency waveform leader, NovelSat NS4 enables up to 45% higher spectral efficiency compared with DVB-S2, and typically 17% higher than DVB-S2X.
The new NovelSat NS4 waveform, like all NovelSat features and options, is a software upgradable option that can be implemented Over-the-Air (OTA) on all NovelSat satellite modems, modulators and demodulators.
The technical advantages of NovelSat NS4 rely on advanced features including unsurpassed 2% Roll-off-Factor (with modes enabling 5% and up to 20% ROF, as well), enhanced spectral efficiency algorithms and improved tolerance for signal impairments and all types of interference.
NovelSat NS4 is the satellite transmission technology that is best positioned to adapt to future trends such as HTS, Ka band, LEO/MEO constellations and the ever increasing demand for satellite video and data bandwidth.
