01 / About — Who we are

From fishing cords to holding satellites.

Founded in 2008 in New Bedford, Massachusetts, OrbCord Inc (orbcordinc.com) started as a high-performance rope maker. Today we are the leading US manufacturer of orbital tether systems — ultra-light cords that generate power, de-orbit debris, and connect spacecraft.

Our 42,000 sq ft facility braids, coats and plasma-treats fibers that survive atomic oxygen, UV, micrometeorites and -180°C to +220°C swings. Every meter is X-ray inspected, proof-loaded and shipped with a digital twin.

02 / Technology
Physics on a string

Three core platforms. One goal: make orbit sustainable, powered and connected without propellant.

Electrodynamic Tethers (EDT)

Bare-wire + braided cords cut Earth's magnetic field to generate up to 5kW or produce drag for de-orbit. No fuel. Just physics.

Electrodynamic tether
🧬

Hoytether™ Multiline

Redundant 4-line braided architecture survives 97% of debris cuts. Self-healing coating seals micrometeorite hits in seconds.

Mission

ISS Tethered Inspection 2024

12.4 km OrbCord Hoytether deployed from Cygnus, towed inspector cam around ISS without thrusters. Tension control ±2%.

Formation flight

TwinSat Formation – No Propellant

Two 180kg sats held 500m apart for 11 months using momentum-exchange cord. Saved $2.1M in fuel.
