SEDAP-Express is an exceptionally fast path to integrate new applications, sensors, effectors or other similar things into the ecosystem of MESE. That's why it is intentionally kept simple and offers several technical ways of communication. Of course, this results in limitations, but in most cases where quick and easy integration is required, these are negligible. If increased demands arise later on, the “bigger” SEDAP API respective MESE interface can be used if necessary.

SEDAP-Express is licensed under the “Simplified BSD License” (BSD-2-Clause). Therefore, there should be no problems using SEDAP-Express in commercial or non-commercial projects or integrating parts of the SEDAP-Express framework.

Below you will find a brief overview and description of the sub-projects. If you have any questions or comments, please write to us here. And even better: If you find any errors, feel free to open a bug report!

In this project you will find all the necessary documents such as the SEDAP Express ICD and all other referenced standards and documents. Hopefully, tutorial videos and such stuff will be added in the coming weeks here to make it as easy as possible for everyone to get started.

Here you can find everything you need to implement SEDAP-Express into your Application and to understand the protocol. In future, we will also provide SDKs in programming languages other than Java. However, these will then be available via separate repositories.

The main function of that tool is to manually generate messages for test and debugging but also in operational use cases ("sneakernet").

For most cases, this sample client is the right way to get started with SEDAP Express development. TCP has some significant advantages over UDP, so if you are able to use it in your future use case, it is better to start with this one.

This is nearly the same project as the SampleTCPClient, except that in this case you are in the server role. Technically it shares the main sources with SampleTCPClient.

Almost the same client as the TCP variant, but for use cases in which only UDP can be used or is required for other reasons.

If you want to implement a REST API client for SEDAP Express, you can use this sample client as a basis. It already contains everything you need for a smooth start.

The protocol buffer standard is another method for exchanging SEDAP Express messages. You can see how it works in this example client. As always, the required libraries can already be found in the libs folder of the project.

This is another example client that can be used as a basic structure for your new client if you need to communicate via a serial line.

This mockup simulates the real SEDAP-Express connector of the MESE framework. It answers your acknowledge request or heartbeats. You can take it also for verifing and debugging your own SEDAP-Express client software. Also, it's intended to be a simple kind of Command&Control (C2) system simulator by providing a simple map with MIL-STD-2525C icons. The engine uses the standard NASA WorldWind framework without our own multithread and other modifications.
