# Build
These arguments can be used to build a visibility cone object :
* An id, a name, a cylinder, an availability : (**this visibility cone will have a fix height of a terrestrial radius**)
```Java
new VisibilityCone visibilityCone = new VisibilityCone(id, name, cylinder, avalability);
```
* An id, a name, a cylinder, an availability, a [Satellite](Satellite) : (**This constructor allows the visibility cone to reach only the given satellite, so the height is fixed to the altitude of the satellite**)
* An id, a name, a cylinder, an availability, a [satellite](Satellite) : (**This constructor allows the visibility cone to reach only the given satellite, so the height is fixed to the altitude of the satellite**)
```Java
new VisibilityCone visibilityCone = new VisibilityCone(id, name, cylinder, avalabilityn satellite);
new VisibilityCone visibilityCone = new VisibilityCone(id, name, cylinder, avalability, satellite);
```
* A [CZMLGroundStation](CZMLGroundStation), a [Header](Header) :
* A [CZMLGroundStation](CZMLGroundStation) :
```Java
new VisibilityCone visibilityCone = new VisibilityCone(groundStation, header);
new VisibilityCone visibilityCone = new VisibilityCone(groundStation);
```
* A [CZMLGroundStation](CZMLGroundStation), a [Header](Header), a [Satellite](Satellite) :
