Just 400 km above the earth’s crust, a large satellite is circuiting the earth. It is none other than the International Space Station, in its low earth orbit within the thermosphere. In this atmospheric layer it encounters some molecules of the atmosphere, unlike much higher orbits in which manmade satellites move. Some of these are outside the gravitational field of the earth altogether, which means they must be able to function in the extreme vacuum conditions of outer space.
Such satellites contain a wealth of equipment that is designed to be used at remote locations beyond the planet’s surface. These must be tested to ensure they comply with requirements in laboratories and settings on the earth before they are put into operation in space.
Such scientists and researchers can now look forward to a setup that lets them test and complete their projects with success, whether it is a space device or just research into the effect of a low-pressure environment on matter.
This type of environment allows them to understand precisely how their devices and components will operate under a range of temperatures and pressures. It is vital to test all components meant to enter the limits of the atmosphere and outer space to confirm their resistance under harsh and demanding conditions.
Among the most important aspects of such a testing simulation that conforms to an expected space environment are sophisticated pressure and temperature controls. Pressure control is achieved using a pressurized container that can attain high degrees of vacuum using cryogenic or turbomolecular pumps, in connection with a mechanically operated roughing pump.
This is combined with a system for temperature control that makes use of active surface heating and cooling in conjunction with coatings that selectively absorb solar radiation, so that they can isolate any radiation that is in excess and vent it from the system. In this way, Angstrom has fulfilled the demand for temperature ramping with impressive success, as well as the need to keep the temperature stable within the user-defined limits.
The platen has a temperature range that depends on how it is heated and cooled. The range goes from LN2 cooled -60 oC to 150 oC on heating. Thus, Angstrom has successfully created a most advanced space simulation system which offers the capability of precise temperature and pressure regulation, along with necessary pumps and data monitoring facilities.
Dependable, Cutting-Edge Technology with Cost-Effectiveness
The space simulation platform from Angstrom uses only tried and tested components, including pumps, vacuum chambers and fluid circulators. The rigorous testing in a high-vacuum environment under varying temperature and pressure conditions makes sure that customers receive excellence at a very affordable price. This system includes the best design for such setups, along with installation to the client’s requirements, such as the desired pressure controls and system sizes.
The simulator is compatible with powered equipment, which means environmental testing can be used over a wide range, such as X-rays, light spectrum emitters, and electromagnetic radiation emitters at various frequencies. Angstrom’s space simulation system clients testify to the superior performance of these platforms compared to other commercially available systems in almost every area, in spite of the moderate budget. It is a cause of immense pride for Angstrom to know that much space equipment in use today was first proved out on these simulation systems, and the company guarantees the high quality, dependability and safety of these products.
