Mx-SAT Mx-SAT

Objectives

The scope of the ARTES C&G Technology Mx-SAT is to prepare the groundwork and mitigate the risk and challenges for candidate improvements to the Newtec Dialog® system.

The main driver for this development will be HTS and VHTS satellite systems, improved scalability and higher efficiency.

The main goals of the ARTES C&G Mx-SAT project are to prototype key components (return link and the Dialog® processing platform) of the system in order to:

  • Anticipate on the requirements to handle the high throughputs associated with HTS and VHTS systems.
  • Investigate applicability of technology advancements on the Newtec Dialog® system
  • Tackle and resolve shortcomings of the existing Newtec Dialog® system
  • Mitigate risk (performance, cost, time to market).

Challenges

The key issues are:

  • Low Cost of ownership for the subscriber;
  • Network capacity enhancement
  • Low network capex and opex cost;
  • Network scalability: support from several hundred to hundred thousand of user terminals and high overall throughput (>10 Gbps);

Benefits

Benefits include:

  • Improved scalability
  • Lower opex
  • Improved density
  • Prepared for the new technology evolutions on the satellite

Features

Scalable and efficient Point to multipoint satellite communication system with fixed and mobile, consumer and professional satellite terminals.

System Architecture

The Newtec Dialog® system contains a Newtec Dialog® platforms and Newtec Dialog satellite terminals.

Plan

The project comprised 2 steps over 36 months. Step 1 contained proof of concepts and small scale verification of the improvements. The second step covered large scale verification of the proof of concepts of step 1, and introduced additional proof of concepts. 

Current status

The Mx-SAT project is completed in June 2020.

The main achievements of are:

  • Next generation Physical Layers: MxDMA MRC (multi-resolution coding) that unites SCPC (single carrier per channel) efficiency and TDMA (time-division multiple access) scalability has been prototyped
  • Technologies for the Next Generation Terminal Portfolio: a low-cost linear transceiver capable to make the Terminal Portfolio ready for MxDMA MRC technology has been prototyped
  • Flexibility & scalability of the Gateway: The verification of prototypes has confirmed candidate technologies, improving flexibility and scalability for the Newtec Dialog® System.

The Mx-SAT project is followed-up by the product development of the associated enhanced technologies in ARTES MRC-SAT activity.
