Orbital Constellation

The paper presents the problem of ensuring support of the flight of a group of small spacecraft (microsatellites) taking into account the small mutual distances between them. The purpose of using the orbital constellation specified is to create a radio communication system to control remote objects like unmanned aerial vehicles and ground robots located in hard-to-reach areas of the Earth from the Central ground station. To reduce the cost of microsatellite design, it was decided to rigidly fix the receiving and transmitting antennas on their housings and use the spatial orientation of the entire apparatus for antenna guidance. This seriously complicated the tasks of navigation and orientation of microsatellites in a formation and required the development of a new method for determining the orientation of a single microsatellite. The essence of the method is to process the image obtained by means of a video camera mounted on a nearby microsatellite. We used methods of computer vision. The results of mathematical modeling simulation, as well as the results of full-scale bench experiment confirming the efficiency of the proposed method are presented.

We propose a new layout for the Offner imaging hyperspectrometer that is utilized onboard small space vehicles. The layout is based on a method of adjusting the adaptive temperature-dependent optical scheme by moving just two coaxial optical components located inside the hyperspectrometer. We present the results of modeling for a temperature range of −40 to +45 °C and an optical experiment using a heat and cold chamber for the range of 12 to 40 °C, proving the basic functionality of the proposed layout. Based on simulation results, the new layout is supposed to allow the hyperspectrometer to operate in a temperature range of −40 to +45 °C without its optical characteristics deteriorating, thus making it suitable for work onboard space or stratospheric vehicles.

Autonomous Docking

Over the past decade, small satellites have gained the interest of the space industry as a new and cost effective approach for servicing space assets. To address the special constraints inherent to the component miniaturization required for these satellites, researchers in the Space, Automation and Manufacturing Mechanisms Laboratory (SAMM) are exploring foldable mechanisms and their effectiveness for providing autonomous rendezvous and docking capabilities for small space vehicles. This paper focuses particularly on the design of autonomous docking mechanisms for space vehicles within the small satellite class known as picosatellite (size and mass requirements: 1 kilogram mass within a 10×10×10 centimeter cube). The docking mechanisms deployment scenario is a dual satellite system comprised of two small satellites (a chaser and a target). The chaser has attitude and translational control capability, while the target is a passive satellite having only attitude stabilization capability. This paper will first present a review of the existing docking mechanism technology utilized in space. This is followed by details of a foldable mechanism approach for providing small satellites autonomous docking capabilities. This includes geometric and dynamic analysis conducted in ADAMS software simulations.

The Russian Federation

Innovative development of the national economy, that has been declared in the Conception of long-term social and economic development of the Russian Federation, has become especially important in the modern situation characterized by geopolitical challenges and threats. Russia is looking for new possibilities to strengthen its competitive position in the global economy. One of the most promising innovative development areas is space science and technologies. Space technologies of manned flights developed in Russia have always been exceptionally competitive. However, in the last decade the onset of new aerospace industries in such countries as China, India or the USA has jeopardized the Russian Federation position of the world leader in this field. In this context such new trends in space technologies as the design, manufacture and launching of small-size space vehicles may be interesting both in terms of advanced engineering and technological solutions and in terms of commercial application of innovative low-cost space products. There are already several very positive practical examples of this engineering field development that involves the adoption of the so-called three-spiral theory describing the interaction between the state, science and business. One of such examples is the Southwest State University that has accumulated an extensive experience of long-time cooperation with Roscosmos (Russian Space Agency) core engineering businesses in the area of small space vehicle design and manufacture. This is a unique experience that has no parallels in Russia or abroad. In terms of economics such integration presents a good object for the investigation of system interaction between national authorities, businesses, educational and scientific institutions. It also makes a sound basis for the successful dissemination of the know-how.
