Due to operating conditions in space that are the harshest imaginable, space programs must have complete confidence that the cables connected to critical systems will continue to perform under that stress. And because repairs are not easy to make outside of planet Earth, these cables must not only be rugged but also boast decades of proven success. That’s where GORE® Space Cables for Traditional Space Applications from W. L. Gore & Associates come into play.

Improve Signal Integrity for Critical Data Transmission
Data transmission between various systems on a spacecraft is crucial to the success and safety of the mission — the cables used to transmit data have a direct impact on the quality of the signal and the time required for transmission. For example, if the cable system used for data transmission fails, the communication between the craft and mission control could be lost. Cable performance is based on reliability, durability and signal integrity, all of which can be compromised by electrical, mechanical and environmental stress.
In today’s aerospace missions, environmental stress can include extreme temperatures, chemicals, abrasion and extensive flexing. These conditions often call for cables that are smaller, more lightweight and offer long service life.
GORE Space Cables, Types GCX/GTX/GBL for dataline applications answer these challenges. Qualified according to ESCC 3902/002, the cables combine excellent electrical performance with mechanical robustness to provide outstanding signal transmission up to 1 GHz in the most difficult situations. Designed with wires of identical electrical length, the cables have a conductor time delay that differs by less than 0.1 nsec/m.
The cables’ small size and minimum bending radius make them easy to install in tight places. Because they’re so lightweight, the cables minimize the problems associated with balancing difficult mass budgets. Manufactured as coaxial, triaxial and balanced lines, the cables offer low capacitance and low signal attenuation. Additionally, they provide constant characteristic impedance along the entire cable with minimal reflections, and are listed on the ESA QPL (Qualified Parts List).
GORE Space Cables, Types GBL/GCS/GTX for dataline applications are proven to provide the lightest, most reliable rate of data transmission available in today’s market. They have provided outstanding performance in such applications as high-resolution cameras and digital signal processors for satellites, telescopes, the International Space Station (ISS) and other mission-critical operations.
The Science Behind the Cables
The key to the space cables’ outstanding performance is the proprietary material used in the cable insulation: expanded polytetrafluoroethylene (ePTFE).
At high frequencies, the electrical properties of the insulation become extremely important, particularly the dielectric constant (εr). The εr for air is 1.0, and the ideal value for cable insulation material should be as close to 1.0 as possible. Expanded PTFE has an εr of 1.3, which means that ePTFE facilitates low capacitance and minimal attenuation along with high signal speed in GORE Space Cables, Types GCX/GTX/GBL for dataline applications. Because ePTFE is chemically inert, the cables can even be used at cryogenic temperatures or as high as 260°C for short periods of time.
Continuing Gore’s heritage of contributing cables to spacecrafts — including the Mars Rover and the Apollo 11 mission to the moon — GORE Space Cables, Types GCX/GTX/GBL for dataline applications are trusted by some of the most important operations in spacecraft today and in recent history. These include:
- Express MD1/MD2
- Intermediate eXperimental Vehicle (IXV)
- International Space Station (ISS)
- James Webb Space Telescope (JWST)
- NASA Lunar Reconnaissance Orbiter
Aboard these spacecrafts, our cables have served a number of uses. They protect signal transmission in:
- digital signal processors
- high-resolution cameras, sensors and detectors
- high-speed subsystem interconnects
Without the performance of GORE Space Cables, Types GCX/GTX/GBL for dataline applications, these operations could be interrupted — for instance, preventing satellites from transmitting images back to Earth. Our cables’ superior electrical performance and mechanical robustness ensure this will never happen.
