The OUTPOST library (Open modUlar sofTware PlatfOrm for SpacecrafT) is developed at the German Aerospace Center (DLR) and provides an execution platform targeted at embedded systems running mission critical software. The library set up to be modular, allowing the user to choose which modules to use and which modules to leave out.

OUTPOST is split into two repositories outpost-core contaning the base environment and outpost-satellite containing the satellite specific modules.

Modules

This repository contains the following software modules:

• utils

  A collection of useful bits and pieces. The reuseable unit test harness is located here.

• time

  Type safe time management functions. Provides classes to convert between time representations, e.g. Unix Time to GPS or TAI.

• rtos

  RTOS wrapper layer. Allows to build OUTPOST on different operating system. Supports RTEMS, FreeRTOS and all POSIX compatible OS.

• hal

  Hardware abstraction layer for communication interfaces.

• smpc

  Simple Message Passing Channel. Provides a very basic, but fast publish/subscribe based communication middleware for objects living in the same address space.

• l3test

  Lua based testing framework. Allows to run Lua scripts as part of the unit tests.
