The Ariane 5 rocket will take off next Tuesday to launch a satellite to make data transmission faster and better. Ruag Space provides onboard computer, thermal insulation and solar reflectors that dissipate heat.


The European Space Agency (ESA) Data Relay Satellite System (EDRS) aims to enable faster and better data transmission between satellites and ground stations. It is the most advanced laser communication network to date and helps Earth observation satellites transmit large amounts of data to Europe almost in real time.

EDRS-C is the first satellite of this program. It will be launched from the European Space Center at Kourou, French Guiana. The launcher launcher’s payload cap is provided by Ruag Space, the company said Friday in a statement.

This structure offers various protections. It protects against the inclement weather on the firing point, the acoustic effects after ignition of the engines, the resistance of the air and the heat of friction in flight. It is abandoned at an altitude of about 110 kilometers.


Solar reflectors


The EDRS-C satellite also benefits from protection against heat and cold in the space developed by Ruag. The insulation consists of several layers of a metallized polyimide sheet. Each layer is thinner than a human hair.

Ruag Space’s optical solar reflectors provide the satellite with additional thermal protection. These mirrors help the satellite dissipate the excessive heat it generates in space. Insulation and reflectors were produced in Austria. Ruag also supplies the EDRS-C onboard computer. It controls and monitors the payload of the satellite and many other subsystems.


Ruag Space is the space division of the Swiss technology group Ruag. It employs more than 1,300 people in 13 locations in Switzerland, Sweden, Germany, Finland, USA and Austria.
