Space projects

"There is hardly a space project in Luxembourg that did not have at least one EmTroniX component on board."

Luxemburger Wort - 3 Nov 2020

For more than 13 years, we have been developing a strong knowledge of the new space industry.
With our first project, the Pathfinder 2, EmTroniX has demonstrated to be capable of providing high quality and reliable electronics which resist to the space environment.

This technology, among other applications, would allow for an orbiting satellite to manufacture very long antenna booms in space. With the appropriate antenna configurations, it would enable the collection of Radio Frequency (RF) data from devices transmitting pertinent power as well as frequencies to be geo-located.

GHOST - ESA/SES
2017 - 2021

The goal of this project was to design, develop and validate a novel on-ground measurement system for satellite In-Orbit-Test (IOT). The IOT measurement system is based on non-intrusive spread spectrum test signals and advanced DSP techniques to measure key payload parameters. It allows the verification and monitoring of in-orbit wide band satellite transponders without interrupting customer services. It also avoids interfering with other satellites during orbital movements.

EMTRONIX CONTRIBUTION

  • System level analysis, architecture definition and detailed design

  • Hardware design, implementation, prototyping and validation

  • Measurement DSP algorithms design, analysis, simulation and FPGA implementation

  • Firmware/Software full implementation, integration and validation

Proximity 1 SDR autonomous transceiver - ESA/Qinetiq
2018

This activity was undertaken in the frame of an ESA study aiming to provide the architecture, define the DSP algorithms, and implement the design of an SDR autonomous transceiver for a Mars orbiter, in view of a future flight qualified unit implementation. This anticipates the future need for a Mars orbiter with an autonomous Proximity-Link transceiver, due to the increasing number of planetary missions including Mars rover and lander elements from different agencies.

The proposed transceiver is a full autonomous and SDR system that has the ability to identify unknown attributes of received signals and automatically reconfigure itself accordingly, without explicit pre-configuration or reprogramming of its functions. Specifically, it implements innovative DSP techniques for the classification and estimation of every unknown parameter of incoming signals including modulation type, data rate, modulation index, coding type, SNR, frequency and timing.

Thanks to its high performing algorithms and optimized FPGA-based design, the proposed autonomous transceiver allows the orbiter to communicate with any current or future landed element automatically, offering the required flexibility and adaptability, and avoiding the need of ground intervention to reconfigure the unit.

EMTRONIX CONTRIBUTION

  • Orbiter UHF transceiver unit requirements analysis and specification,

  • Orbiter UHF transceiver unit architecture definition,

  • Autonomous receiver DSP algorithms design, analysis and simulation,

  • Hardware and FPGA implementation of the software defined and autonomous orbiter transceiver unit,

  • Algorithms validation and testing in the selected digital platform FPGA based.
