Data transmission is essential to the success of every mission that launches satellites into orbit. If data can’t be transmitted, we can’t stay connected to access information online and effectively monitor the earth. The emerging NewSpace private sector also wants low-weight cables that fit in smaller launch vehicles and satellites, plus cost less for use in frequent missions.

Gore can meet these challenges. By combining our extensive materials expertise with decades of proven traditional spaceflight heritage, we offer a reliable, cost-effective high data rate solution for NewSpace applications.


GORE Space Cables, SpaceWire are proven to maintain constant bi-directional, high data rate transmission up to 400 Mbps with minimal crosstalk, low insertion loss and low skew. They use a serial, point-to-point dataline with reliable LVDS (Low Voltage Differential Signals). We support LVDS by using uniquely engineered materials that allow data to pass through the cable without significant signal loss. By combining this LVDS technology with standard hardware protocols, our cables offer a simple cable management solution without the need for customized program designs.

Our unique materials are also high strength, so these cables can easily tolerate the most severe conditions. For instance, extreme temperatures, shock and vibration during launch sequences. Or radiation, outgassing and intense temperature changes during satellite missions. Plus, our materials have the added benefit of being lightweight, so they can be easily integrated into smaller launch vehicles and satellites where space is a premium.


GORE Space Cables, SpaceWire are engineered to perform reliably in a variety of applications, including:

  • command and data handling (C&DH)
  • high-resolution cameras
  • radar sensor equipment
  • sensor, mass memory unit and telemetry subsystem interconnections

If you have any questions or to discuss your specific application needs, please contact a Gore representative.


GORE Space Cables for SpaceWire applications provide system architects and engineers with many benefits that improve electrical and mechanical performance such as:

  • constant bi-directional, high data rate transfer up to 400 Mbps
  • proven minimal crosstalk, low loss and low skew
  • serial, point-to-point dataline with reliable LVDS technology
  • high-strength build tolerates extreme temps, chemicals, radiation, shock, vibration, more
  • small, lightweight materials help meet challenging mass budgets
  • reduce costs with simple cable management solution over customized program designs
  • cost-effective solution ideal for NewSpace private sector companies
  • leverage proven performance with 100% failure-free flight record in hundreds of traditional spaceflight programs
