Introducing the Keystone Separation System

Simple Solution, Sophisticated Results.

The Keystone Separation System delivers smooth, low-shock separation making it one of the strongest and most dependable systems on the market today, supporting payloads up to 850kg.

About Keystone

Engineered for unparalleled reliability and performance.

Keystone’s ultra-streamlined design has been rigorously tested to ensure consistent results under even the most strenuous flight conditions. Available in 8”, 15”, and 24” sizes, it meets the diverse needs of smallsat missions, including handling high-mass (850kg) payloads.

PRODUCT BENEFITS

Redefining deployment for high-mass payloads. 

Streamlined, Intelligent Design

Keystone consists of only four key components enabling fast, straightforward integration and operation. It’s the first separation system fully tested to launch vehicle flight levels, ensuring launch vehicle providers won’t need to accommodate untested risks.

Exceptional Structural Performance

While most high-mass satellites require a four-point separation signal—often triggering additional costs from the launch provider—Keystone’s structural strength allows these payloads to fly using a single-interface solution.

Compact, Low Shock

Keystone measures only 2.10” in height with precision-engineered separation springs which provide smooth, even payload deployment with minimal shock and low tip-off rates—regardless if your payload mass is 80 kg or 850 kg!

Cost-Effective and U.S. Made

Manufactured in the U.S., Keystone provides rapid launch readiness with high tolerance machining and scalable quality–which greatly reduces not only the mission complexity but the overall cost.
