From Global VSAT to Oilcomm, from China Satellite to APEX, and from Futurecom to GlobalMilsatcom the consistent theme we are hearing from our partners is the need for continued innovation in bandwidth efficiency and performance. This helps our partners to drive OPEX costs down and to plan for what’s next to come with High Throughput Satellite (HTS).
At iDirect, we are passionate about RF innovations. As you know, today you can optimize the iDirect platform around RF efficiencies in many ways.
- Adaptive carriers with ACM and ATDMA to maximize availability and efficiency
- Reducing roll-off factors to maximize throughput
- DVB-S2 and TDMA waveform enhancements such as distributed pilots to run your networks optimally
And with new technologies on the horizon, we are continuing to push the limits on efficiency for our Evolution Platform:
- Offering more efficient MODCODs, such as 32APSK and numerous FEC and block sizes
- Saturating larger and larger HTS transponders with non-linear pre-distortion
- Active DVB-S2X developments
HTS is driving the need to capitalize on the higher performance and throughput in the most efficient ways. Thus the reason why we have spent some time looking at the new HTS architectures. Take the transponder size for example, not so long ago, 36 or 72 MHz transponders were so common on satellites that industry consultants used this as a standard unit to measure the growth in capacity available in the market. Now the norm is 100 MHz or higher on the new HTS satellite architectures, going soon on to 500 MHz.
For Satellite Operators that means they need to optimize the power being used to enable larger amounts of spectrum.
For iDirect, as the ground segment technology provider, this means optimizing the inbound transmissions to support higher symbol rates and a higher number of carriers. It also drives the need for capabilities to support a wider range of frequencies. On the outbound it means the need for much larger symbol rate carriers and more efficient MODCODs, such as 32APSK and oftentimes non-linear pre-distortion to drive greater bandwidth efficiencies. How so? 32 APSK gives you more bits per Hertz and non-linear pre-distortion adjusts the transmitted signal to accommodate non-linearity in the channel, allowing you to transmit up to the compression point. Depending on the transponder configuration, non-linear pre-distortion is often required to saturate the entire transponder when operating at 32APSK.
At iDirect, we are working on all such advances: We will be increasing our aggregate Msps rates on the in-and outbound, supporting 32APSK and non-linear pre-distortion as new features.
We will be introducing higher performing line cards that are DVB-S2X-ready to optimize overall bandwidth efficiencies, increasing network availability and allowing you to leverage the performance benefits of HTS.
Couple this with the latest features and enhancements from Adaptive TDMA, Layer 2 over satellite and DVB-S2 enhancements, to the expanded capabilities of the X1 and X7 remotes and you will find on #MySatelliteEvolution how our partners are leveraging their platforms to drive new applications in the most cost-effective ways.

And we have more exciting growth plans for our Evolution platform. In subsequent blogs we will address how we take remote performance, extensibility and scalability to new levels.
