NanoSat MO Framework
The NanoSat MO Framework (NMF) is a software framework for Miniaturized_satellite, nanosatellites based on CCSDS_Mission_Operations, CCSDS Mission Operations services. It was developed by Graz University of Technology in partnership with the European Space Agency. The framework facilitates the monitoring and control of the nanosatellite software applications as well as the interaction with the nanosatellite platform. This is achieved by using the latest CCSDS standards for monitoring and control, and by exposing services for common peripherals among nanosatellite platforms. Furthermore, it is capable of managing the software on-board by exposing a set of services for software management. Installed apps onboard can be started and stopped from ground via the NMF. Apps can retrieve data from the nanosatellite platform through a set of platform services. Additionally, it includes CCSDS standardized services for monitoring and control of apps. An NMF App can be developed, distribute ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Miniaturized Satellite
A small satellite, miniaturized satellite, or smallsat is a satellite of low mass and size, usually under . While all such satellites can be referred to as "small", different classifications are used to categorize them based on mass. Satellites can be built small to reduce the large economic cost of launch vehicles and the costs associated with construction. Miniature satellites, especially in large numbers, may be more useful than fewer, larger ones for some purposes – for example, gathering of scientific data and radio relay. Technical challenges in the construction of small satellites may include the lack of sufficient power storage or of room for a propulsion system. Rationales One rationale for miniaturizing satellites is to reduce the cost; heavier satellites require larger rockets with greater thrust that also have greater cost to finance. In contrast, smaller and lighter satellites require smaller and cheaper launch vehicles and can sometimes be launched in multipl ...

Software Framework
In computer programming, a software framework is an abstraction in which software, providing generic functionality, can be selectively changed by additional user-written code, thus providing application-specific software. It provides a standard way to build and deploy applications and is a universal, reusable software environment that provides particular functionality as part of a larger software platform to facilitate the development of software applications, products and solutions. Software frameworks may include support programs, compilers, code libraries, toolsets, and application programming interfaces (APIs) that bring together all the different components to enable development of a project or system. Frameworks have key distinguishing features that separate them from normal libraries: * ''inversion of control'': In a framework, unlike in libraries or in standard user applications, the overall program's flow of control is not dictated by the caller, but by the frame ...

CCSDS Mission Operations
The Spacecraft Monitoring & Control (SM&C) Working Group of the Consultative Committee for Space Data Systems (CCSDS), which sees the active participation of the main space agencies, is defining a service-oriented architecture consisting of a set of standard end-to-end services between functions resident on board a spacecraft or based on the ground, that are responsible for mission operations. Identification of the problem There is a general trend toward increasing mission complexity at the same time as increasing pressure to reduce the cost of mission operations, both in terms of initial deployment and recurrent expenditure. Closed, or ‘monolithic’ mission operations system architectures do not allow the re-distribution of functionality between space and ground, or between nodes of the ground system. This lack of architectural openness leads to: * lack of interoperability between agencies; * lack of re-use between missions and ground systems; * increased cost of mission spe ...

Java (programming Language)
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers ''write once, run anywhere'' ( WORA), meaning that compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but has fewer low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as reflection and runtime code modification) that are typically not available in traditional compiled languages. , Java was one of the most popular programming languages in use according to GitHub, particularly for client–server web applications, with a reported 9 million developers. Java was originally developed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apache Maven
Maven is a build automation tool used primarily for Java projects. Maven can also be used to build and manage projects written in C#, Ruby, Scala, and other languages. The Maven project is hosted by the Apache Software Foundation, where it was formerly part of the Jakarta Project. Maven addresses two aspects of building software: how software is built and its dependencies. Unlike earlier tools like Apache Ant, it uses conventions for the build procedure. Only exceptions need to be specified. An XML file describes the software project being built, its dependencies on other external modules and components, the build order, directories, and required plug-ins. It comes with pre-defined targets for performing certain well-defined tasks such as compilation of code and its packaging. Maven dynamically downloads Java libraries and Maven plug-ins from one or more repositories such as the Maven 2 Central Repository, and stores them in a local cache. This local cache of downloaded arti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

OPS-SAT
OPS-SAT is a CubeSat by the European Space Agency (ESA) and it is intended to demonstrate the improvements in mission control capabilities that will arise when satellites can fly more powerful on-board computers. The mission has the objective to break the cycle of "has never flown, will never fly" in the area of satellite control. It was the first CubeSat operated directly by ESA. The satellite has an experimental computer that is ten times more powerful than traditional ESA on-board computers. This on-board computer provides an experimental platform to run software experiments on board. One innovative concept is the deployment of space software in the form of apps. This concept is enabled by the NanoSat MO Framework (NMF) and allows Apps to be uploaded to the spacecraft and then started on board. This is a new concept that ESA has successfully demonstrated in space. OPS-SAT has been launched at 08:54:20 UTC on 18 December 2019 exactly twenty-four hours later than originally plann ...

Service Composability Principle
In computing, service composability is a design principle, applied within the service-orientation design paradigm, that encourages the design of services that can be reused in multiple solutions that are themselves made up of composed services. The ability to recompose the service is ideally independent of the size and complexity of the service composition. This principle is directly responsible for the agility promised by SOA as it promotes composing new solutions by reusing existing services.Michael PouliEvolution of principles of Service Orientation: Service Statelessness, part 7Online].Date accessed: 21 April 2010. Purpose The concept of developing software out of independently existing components encourages the concept of composition. This is the underlying concept within object-orientation where the end product is composed of several interlinked objects that have the ability to become part of multiple software solutions, no matter how complex the solution is. The same composit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
