Space - GNAT Pro for Safety-Critical

GNAT Pro Safety-Critical is ideal for developing software applications deployed in space vehicles or satellites, which require the creation of high-reliability, mission-critical software.

GNAT Pro Safety-Critical is an enhanced version of GNAT Pro, designed for building high-reliability software. It has many features that help to reduce the cost of developing systems that have to conform to Space standards such as ECSS-E-ST-40C (Space Engineering, Software) and ECSS-Q-ST-80C (Space Product Assurance, Software) and other Mission critical standards. Key to achieving this goal is the product’s fully configurable and customizable run-time library. You can select units in an a la carte fashion, thus limiting the run-time library to just those units that are required for the Ada features used in the application, and you can adapt their implementation if desired.

Space Industry Standards


ECSS-E-ST-40C and ECSS-Q-ST-80C are the software-related standards for use in all European space projects and applications. The Ada language and several AdaCore products and technologies are designed to help in the qualification process, such as SPARK Pro, CodePeer, GNATcoverage, GNATcheck, GNATmetric, GNATstack, qualification data packages, specific run-time libraries, etc.


Featured Project

Argos Satellite Project by Thales

Knowledge Center


  • The InSight webinar series continues with a webinar demonstrating how to write unit tests in a cost-effective way using the AdaCore toolset. More precisely it will show how to generate the unit testing framework using GNATtest, how to run the tests on an emulator such as GNATemulator and how to extract coverage results using GNATcoverage. This is primary aimed at developers and projects managers that already have unit testing infrastructure in place and are looking to reduce maintenance costs, as well as teams that are looking at implementing such techniques with minimal effort.
  • Wind River, Ada Core and Verocel will show the webcast audience how use of COTS technology and best practices in software certification can improve time to market and reduce risk for safety-critical software developers.

    AdaCore will introduce tools and techniques for easing the development and certification costs for applications to be deployed within an IMA architecture. Options for certification approaches will be discussed along with methods for automating these approaches. Full software development environments will be discussed with tight integration of tools and toolsets when they are applicable to the development or safety certification effort for a particular safety standard.

Developer Gems    

  • Gem #63: The Effect of Pragma Suppress

    Ada Gem #63 — The features of Ada have generally been designed to prevent violating the properties of data types, enforced either by compile-time rules or, in the case of dynamic properties, by using run-time checks. Ada allows run-time checks to be suppressed, but not with the intent of allowing programmers to subvert the type system.
