Riedel provides end-to-end communications solutions for Red Bull Stratos skydive

The Red Bull Stratos, the 120,000ft skydive from the edge of space, was a mission that transcended human limits. Riedel Communications provided the entire communications solution for this project, integrating both wireless and wired digital intercom systems. Additionally, Riedel furnished the fiber-based video and signal distribution as well as the wireless video links from the capsule’s onboard cameras — enabling the stunning pictures delivered from the Red Bull Stratos capsule.

Felix Baumgartner, renowned extreme base jumper and sky diver, ascended to 24mi (39km) in a stratospheric balloon and made a freefall jump rushing toward earth at supersonic speeds before parachuting to the ground, breaking three world records with one jump: the highest skydive, the longest free fall, the first to reach supersonic speeds in free fall and the highest manned balloon ride.

For the capsule that transported Baumgartner into the stratosphere, Riedel provided the on-board video control system for nine HD video cameras with specially developed telemetry control. This system was responsible for the control of the video recording and also works as a comprehensive digital video router — not unlike a mini OB truck inside the capsule. It offered complete remote control of the whole video system and featured three HD video downlinks that were dynamically assigned to the selected cameras.


he communications infrastructure on-site included the entire compound, mission control, the production offices, the media/press center and the OB truck. All these facilities and positions were integrated into one single communications infrastructure via a Riedel Artist Digital Matrix system. Artist is a fiber-based communications solutions that offers highly flexible, reliable and decentralized communications in broadcast-quality audio. The redundant ring topology makes Artist systems an extremely reliable solution for mission-critical applications such as the Red Bull Stratos project.

Riedel also furnished the on-site digital radio network with more than 100 radio receivers and 10 channels, which were seamlessly integrated into the wired matrix intercom system. This means radio users were able to directly talk to intercom users and vice versa.

All video signals on ground were distributed and routed with Riedel's MediorNet technology. MediorNet is a fiber-based real-time network for HD video, audio, communications and data signals that also provides integrated signal processing saving time, cost and effort in installation and maintenance. For the Red Bull Stratos project, 24 Riedel MediorNet nodes were installed in a redundant ring topology to provide maximum reliability. In case of a potential connection loss between two nodes, the signals would have still been distributed due to the redundant topology. The connection to the launchpad of the capsule was also realized with the MediorNet system — this time with two MediorNet Compact frames that were connected to the main system. All links in the MediorNet system were realized with Riedel PURE, an extremely robust, tactical fiber cable for demanding mobile applications that is equipped with ruggedized Neutrik OpticalCON Quad connectors. 

The MediorNet backbone transported all video signals of the Red Bull Stratos mission as well as all signals from the OB truck and from the tracking truck. It also distributed the broadcast audio between Mission Control and the recording facility. Furthermore, the data of the telemetry that was used for some broadcast applications such as the Moving Map was transported via MediorNet. 

In addition to the video transport, MediorNet also serves as a network backbone for the on-site Internet connection providing the Ethernet connectivity in all areas of the compound.
