<p>Augmented reality (AR) displays are image-forming systems that use a set of optical, electronic, and mechanical components to generate images somewhere on the optical path between an observer’s eyes and the physical object to be augmented.</p><p>AR provides a live direct or indirect view of a physical, real-world environment and augments (or supplements) this view with computer-generated input such as sound, video, graphics, 3D objects or GPS data.</p><p>AR&nbsp;improves users’ experience by enabling them to interact with and learn from whatever they are

Recently, a variety of satellite constellations, some of them featuring over a thousand satellites, were announced. While similar concepts for large constellations already existed in the past, existing satellite constellations hardly ever feature triple-digit satellite quantities. At the time of writing, the world’s largest constellation is operated by Planet Labs and consists of 190+ Dove spacecraft.

Recent trends in miniaturisation of space hardware combined with the provision of affordable and standardised spacecraft components and structures is opening up space to new players and is rapidly increasing the traffic into orbit.

In summary, this activity used simulated and analysed parameters for each component to define the requirements for each application. For the flight model, the most important parameters are power consumption, cost and mass of the components. The power consumption and mass of components are acquired from the datasheets. Since space qualification is needed for these components the cost estimation is a difficult task. For example, even for the passive component the price difference between non-qualified, qualifiable and qualified devices is rather high.
