SpaceDataHighway

SpaceDataHighway

The SpaceDataHighway鈩 (SDH) is a public鈥損rivate partnership between ESA (European Space Agency) and AG真人计划. The SpaceDataHighway service utilises the AG真人计划 owned and operated European Data Relay System (EDRS) laser communication infrastructure to provide this high bandwidth capability for both LEO satellites and airborne platforms.

The laser terminal was built by TESAT-Spacecom, an AG真人计划 subsidiary, and funded by the DLR German Aerospace Center. The European Commission is the first Customer of the SpaceDataHighway. The Sentinel-1 and Sentinel-2 satellites of Copernicus, the European Commission's Earth observation programme, are equipped with laser communication terminals that will significantly accelerate the delivery of large volumes of time-critical data to Earth monitoring centres within Europe. SpaceDataHighway represents a step change in the speed of space communications. Ultra-broadband laser communications and the geostationary orbit of the relay satellites combine to deliver a unique, secure, near real time data transfer service, making data latency a thing of the past.

EDRS-A, the first relay satellite for the SpaceDataHighway programme was launched on 30聽January 2016. Positioned at 9掳 East, this first communication node offers coverage from the聽American East Coast until India. EDRS-C was launched in 2019 and is the second satellite and will extend the coverage, capacity and redundancy of the system, positioned at 31掳 East.

The聽SpaceDataHighway will provide data transmission in broadband quality in near-real time through high-precision laser. This makes it ideal:

  • to transfer time-critical and sensitive information, thus increasing a mission鈥檚 staying power and data acquisition capability
  • to gain faster and longer access to your air and space assets
  • to securely transfer information in hostile electronic warfare environment
  • to facilitate Near-Real-Time (NRT) data delivery, minimizing latency of mission critical data collected beyond line of sight
  • to support the transfer of large volumes of data generated by powerful sensors or to enable Combat Cloud concept

Thanks to the laser technology developed by TESAT-Spacecom and DLR, the SpaceDataHighway can transfer high-volume data from Earth observation satellites, airborne platforms, or even from the International Space Station at a data rate of 1.8 gbps and can transmit up to 40 terabytes per day.聽

SpaceDataHighway - Start of Service

 

AG真人计划 Defence and Space starts the initial service of its SpaceDataHighway. This represents a step change in the speed of space communications. Ultra-broadband laser communications and the geostationary orbit of the relay satellites will make data latency a thing of the past.Through laser communication, the SpaceDataHighway can transfer high-volume data from Earth observation satellites, airborne platforms, or even from the International Space Station at a data rate of 1.8 Gbps and can transmit up to 40 terabytes per day.;_LINE_TERMINATEDBe ready to enter the SpaceDataHighway the 28th of November 2016 #SpaceDataHighway;_LINE_TERMINATEDMore informations here : http://bit.ly/2fvwttP Read less Read more

Benefits

For Low Earth Observation (LEO)聽satellites

  • Supports the transmission of large data volumes from LEO satellites
  • High volume data transfer outside ground network vicinity
  • Improved data latency at global scale
  • Enhanced reactivity
  • Routing of data over secure and trusted infrastructure

For Airborne Platforms

  • High Volume data transfer Beyond Line of Sight
  • Resilient communications
  • Resistant to jamming and spoofing
  • Low probability of Interception
  • Low probability of Detection

Features

  • The operational service started in end of 2016 with Sentinel 1A (radar satellite)
  • As of January 2018 all 4 Sentinel satellites are served
  • Data collection capacity/day increased by up to 50% (Sentinel-1)
  • Improved data collection flexibility by clearing on-board storage before crossing Europe
  • Consequential: increased use of Sentinel-1 in dual polarization mode
  • Pre-operational NRT pass-through link tests via SDH and user community successfully
  • Up to 39 link sessions per day with service reliability greater than 99.8 %
  • SDH service routinely achieves, mostly even over-achieves contractually agreed KPIs
  • We have achieved more than 20.000 successful relay links and downloaded more than 1 Petabyte of data space
  • Average communication session duration of 18 mins
