This repository holds the source code to start a basic Yamcs application that monitors a simulated spacecraft in low earth orbit.
You may find it useful as a starting point for your own project.
- Java 8 or 11
- Maven
- Linux x64 or macOS
Here are some commands to get things started:
Compile this project:
mvn compile
Start Yamcs on localhost:
mvn yamcs:run
Same as yamcs:run, but allows a debugger to attach at port 7896:
mvn yamcs:debug
Delete all generated outputs and start over:
mvn clean
This will also delete Yamcs data. Change the dataDir property in yamcs.yaml to another location on your file system if you don't want that.
To start pushing CCSDS packets into Yamcs, run the included Python script:
python simulator.py
This script will send packets at 1 Hz over UDP to Yamcs. There is enough test data to run for a full calendar day.
The packets are a bit artificial and include a mixture of HK and accessory data.
(not yet included in this example)
Running through Maven is useful during development, but it is not recommended for production environments. Instead bundle up your Yamcs application in a tar.gz file:
mvn package
