A CZML file is a subset of [JSON files](https://en.wikipedia.org/wiki/JSON). Hence, a CZML file contains only one array of a JSON file. Objects inside the CZML are nammed **[packet]()**, all the objects we will use are in fact packets.
### The [Header](Header)
### The Header
[Doc here](Header)
The header describes the entire scene and the time the simulation will lasts. It is absolutly mandatory that the header is the first object created while writing in the CZML file.
### Objects that can be added :
#### [Satellite](Satellite)
#### Satellite
[Doc here](Satellite)
The satellite object will create a satellite and its path. The path will be computed with a propagation for the duration of the scene. (**A propagator can create the header in order to setup the propagation parameters before**).
#### [Ground Station](CZMLGroundStation)
#### Ground Station
[Doc here](CZMLGroundStation)
The ground station object will create and display a ground station at the surface of the earth.
#### [Visibility Cone](VisibilityCone)
#### Visibility Cone
[Doc here](VisibilityCone)
The visibility cone is an object that can be build in order to create a [Line Of Visibility](LineOfVisibility) of to display what the station sees. It can be created only with a station then it will not be bounded to a specific satellite. Or it can be created with a satellite and the visiblity cone will have the height of the satellite.
#### [Line Of Visibility](LineOfVisibility)
#### Line of visibility
[Doc here](LineOfVisibility)
The line of visibility is a line that will be displayed only when a satellite is visible in the local sky of a ground station.
#### [Constellation](Constellation)
#### Constellation
[Doc here](Constellation)
The constellation object creates several [Satellites](Satellite) at the same time in order to build a constellation with the number of satellites given and orbital planes given.
