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 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).


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


Benefits include:

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


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.


The project runs over 27 months in 2 steps. The first step contains 4 milestones and is expected to complete in September 2018.  

Current status

The project is currently in step 1. It has achieved the second milestone (MS2) focusing on developments to Gateway Platform scalability and flexibility.
