NTS Los Angeles and NTS El Segundo comprise a significant portion of NTS' Southern California Space & Satellite testing expertise. The facilities are managed by our expert team of engineering and test professionals at the LAX facility and share an expert staff of highly experienced engineers and technicians supported by state-of-the-art facilities to provide a full range of qualification, compliance and reliability testing to customers throughout the world.


NTS leads the industry in testing associated with space technology and can custom engineer chambers and ­ fixtures to conduct a complete range of space related phenomena. NTS is a full service environmental test facility capable of managing your environmental test programs both commercial and military.

A unique blend of specialized engineering experience and customized facilities are in place to economically test items ranging from solar panels to satellites to circuit boards. To keep programs on schedule a wide variety of in-house services, including fixture fabrication and instrument calibration are also available.

NTS' staff of engineers and technicians specialize in supporting the world's most quality conscious industries, including aerospace, defense, electronics and other high technology industries. With some of the most extensive space simulation capabilities in the industry, we can meet almost any space simulation requirement.

Satellite and Space Technology

NTS leads the industry in testing associated with satellite technology and can custom engineer chambers and fixtures to conduct a complete range of space related phenomena including:

  • Fuel cells, Solar panels
  • Composite antennas, Batteries
  • Full qualification and acceptance testing of propellant tanks
  • And various mechanical and electronic devices

Thermal Vacuum Chamber

TV-25: Our Largest Thermal Vacuum Test Chamber

In addition to smaller TVAC chambers, NTS El Segundo designed, built, maintains and operates a TV-25 (25 feet long by 15 feet deep) thermal vacuum test facility for customer - spaceflight hardware. We utilize one control room, two customer rooms, a 3-ton crane within a class 100,000 clean room, two gowning areas, and two uninterruptible power sources connected to an automatically engaged backup generator.

TV-25 Major Capabilities:

  • Thermal vacuum testing for a wide range of components can be accommodated
  • Multiple PID controlled thermal zones to minimize temperature gradient
  • Large size accommodates reflectors, solar panels and small satellites

Environmental & Dynamic Testing

Our technicians and engineers are recognized experts in the performance of a wide array of environmental simulations including space, thermal, shock, and vibration. NTS has a large selection of temperature/humidity chambers including: temperature/altitude chamber up to 60,000 feet, space simulators; acoustic noise, salt fog, sand and dust chambers; solar load test; and thermal shock chambers (air-air and liquid-liquid).

At NTS, combining electro-dynamic vibration and controlled environments simultaneously is routine. Capabilities include: sine, random, sine on random and synthesized shock.

Precision Cleaning CapabilitiesPrecision Space Cleaning

As the preferred precision cleaning supplier for many of our nations aerospace and defense contractors, NTS is an active participant in Space, National Security, and Homeland Defense Programs. These programs require the strict process and cleanliness controls that only a company with over 50 years’ experience can provide.
Working closely with our customers, NTS developed and implemented the cleaning processes necessary to meet the demanding level of process control and system cleanliness required for mission success. NTS continues to develop processes and techniques as new commercial space programs grow. The need to reduce costs and deliver products that meet stringent requirements on time, every time is now more important than ever.
In-process parts and finished products NTS performs precision cleaning and testing on include:

  • Valves and related items
  • Piping and tubing
  • Tanks and cylinders
  • Heat exchangers
  • Gauges and instruments
  • Fittings and fasteners
  • Transducers and sensors
  • Fuel and oxidizer ducts
  • Cryogenic and vacuum jacketed piping

Cleaning Capabilities
