“At Terma we find Ada to be suitable for on-board software development, due to its strengths and proven track record in the field of critical real-time software. The software is tested in a fully simulated environment, ensuring that only integration and system-specific verification need to be performed on the final target. In combination with GNATemulator, GNATcoverage is used to provide very early structural coverage analysis without need to instrument the software under test. For dynamic analysis, GNATemulator is used to perform unit testing of the software using the LEON 3 toolchain, independent of and prior to the availability of the final hardware. The GNATstack tool performs static stack analysis, so that stack size requirements can be verified prior to execution. Complexity and other metrics are automatically monitored using GNATmetrics, while GNATcheck enforces a consistent coding style, and detects well-defined categories of code vulnerabilities. It includes tools that take advantage of the language’s properties to perform additional static and dynamic analysis, reaching even higher levels of reliability. To carry out the Ada development, Terma selected the LEON 3 ELF configuration of the GNAT Pro Safety-Critical development environment. This allows early detection of inconsistencies, either statically (at compile time) or dynamically (during testing). Ada’s ability to define static and dynamic contracts and checks – including features recently introduced in the new Ada 2012 standard – helps developers express requirements directly in the software. The Ravenscar profile (a subset of the Ada tasking features designed for safety-critical hard real-time computing) will be used to ensure that all multi-processing/tasking within the application can be proven deterministic and schedulable. This need for reliability was a principal factor in selecting the Ada programming language for the software development. Terma is – under contract to the European Space Agency (ESA) – the prime contractor for the development of the ASIM instrument including development of the on-board software.ĪSIM will be deployed in space where repairs are costly if possible at all, making reliability of the platform and its software essential. The objective is to search for a correlation between these formations and large thunderstorms, improving our understanding of these phenomena and their influence on the Earth’s climate. GNAT Pro Safety-Critical combined with the GNATemulator and GNATcoverage dynamic testing tools to develop and test the application prior to deployment on the actual LEON 3 embedded processor.ĪSIM is used to detect lightning formations known as “red sprites”, “blue jets” and “elves”, and to detect X-ray and γ-ray discharges. PARIS, NEW YORK, Decem– Paris Space Week 2012- AdaCore today announced that Terma A/S has selected the GNAT Pro Safety-Critical development environment to develop onboard software for the Atmosphere-Space Interactions Monitor (ASIM) that will be mounted on the Columbus module of the International Space Station. Sensitivity - 0.En fr de GNAT Pro Safety-Critical used by Terma A/S for Space Monitor Project.Sample - Cell Lysates, Tissue Extracts, TCM. Use - Measure 2',3'-cGAMP in tissues and cells.This cGAS-cGAMP-STING pathway has been shown to play a critical role in pathogen detection and physiological conditions such as metabolic dysregulation, autoimmunity, and cancer. Subsequently STING induces the TBK1-IRF3-dependent production of IFN-β. Produced in mammalian cells by cGAS (cGAMP synthase) in response to double-stranded DNA in the cytoplasm binding to cGAS, cGAMP binds to the stimulator of interferon genes (STING). 2’,3’-Cyclic GAMP is a novel second messenger in innate immunity that regulates type I interferon (IFN) production. 2’,3’-cGAMP is also referred to as “noncanonical“ cGAMP due to the presence of the atypical 2’-5’ phosphodiester linkage between the guanosine and the adenosine.
