Data transmission is essential to the success of every mission that launches satellites into orbit. If data can’t be transmitted, we can’t access information online and effectively monitor the earth. The growing NewSpace 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, affordable high data rate solution delivered quickly 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 low weight, so they can be easily integrated into smaller launch vehicles and satellites where space is a premium.

We can also manufacture our cables quickly at a price you can afford to meet your time-critical program schedules and tight budgets. GORE Space Cables, SpaceWire meet the challenges of NewSpace by providing all-around durable protection and reliable performance for the duration of the mission.



With reliable LVDS technology at high data rates, GORE Space Cables, SpaceWire deliver unfailing signals in a variety of low Earth orbit (LEO) and medium Earth orbit (MEO) applications, including:

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