 # Build
 
 The CZML ground stration object can be build with :
 
-* A name, an id, an availability, a description, a position, a billboard :
+* A name, an id, an [availability](https://cesium.com/learn/cesiumjs/ref-doc/TimeInterval.html), a [position](Position), a [billboard](Billboard) :
 
 ```Java
 CZMLGroundStation groundStation = new CZMLGroundStation(name, id, availability, position, billboard);
