As operators launch more satellites and more services come online, existing methods of mitigation do not meet the challenge posed by increasing RFI. NovelSat has developed new and innovative technologies to enable satellite users to deliver continuously reliable satellite services even while various types of RFI are present.
go to site To simplify and speed up the process of finding the source of interference The Satellite Interference Reduction Group (SATIRG) developed DVB-CID. This new standard is now mandatory for all modulators in mobile satellite stations (DSNGs) in the US and is available in all NovelSat solutions. It encodes a Carrier-ID (CID) into the satellite transmission signal which contains contact information that can be used to locate and communicate with the operator of the interfering signal.
The NovelSat NS2000 Satellite Demodulator offers advanced receive algorithms to cancel interference. Since there are many types of RFI, each with distinctive characteristics, no single receiver algorithm is applicable. For example, mitigating CW RFI is completely different from cancelling Radar RFI. So, NovelSat developed a set of advanced mitigation algorithms and detection mechanisms to handle all types of RFI.
NovelSat NS3 and NS4 are advanced waveforms that include built-in mechanisms to further increase resilience to interference, as well as other signal-disrupting impediments such as phase noise and weather fluctuations. In addition to boosting spectral efficiency by up to 45% compared with DVB‑S2, NovelSat NS4 exceeds the RFI/Signal ratio of DVB-S2 by as much as 15dB, ensuring dependable transmission well beyond the limits of other solutions.
NovelSat offers enhanced RFI analysis tools in every NovelSat NS2000 Demodulator and every NovelSat modem to enable satellite users to identify RFI incidents in real-time. This is mainly useful for local interference sources which are not visible to the main teleport or broadcast hub.
