+# Satellite Reference System
+
+**Implements** : [CzmlPrimaryObject](CZMLPrimaryObjects)
+
+**Extends** : [AbstractPrimaryObject](AbstractPrimaryObject)
+
+**Example** :
+
+```json
+{
+    "id":"REFERENCE SYSTEM/Keplerian parameters: {a: 7878000.0; e: 0.0; i: 20.0; pa: 0.0; raan: 0.0; v: 0.0;}",
+    "name":"Reference system of : Satellite",
+    "availability":"2024-03-15T00:00:00Z/2024-03-15T10:00:00Z",
+    "position":{
+      "reference":"Keplerian parameters: {a: 7878000.0; e: 0.0; i: 20.0; pa: 0.0; raan: 0.0; v: 0.0;}#position"
+    },
+    "orientation":{
+      "reference":"Keplerian parameters: {a: 7878000.0; e: 0.0; i: 20.0; pa: 0.0; raan: 0.0; v: 0.0;}#orientation"
+    },
+    "model":{
+      "gltf":"./referenceSystem.glb",
+      "scale":0.02,
+      "maximumScale":1000000,
+      "minimumPixelSize":200,
+      "incrementallyLoadTextures":true,
+      "show":true
+    }
+  }
+```
+
+# Properties
+
+**id** - String : Identification of the Satellite Reference System, _default_ : "REFERENCE SYSTEM/{id of the satellite}".
+
+**name** - String : Name of the Satellite Reference System, _default_ : "Reference system of : {name of the satellite}".
+
+**availability** - [TimeInterval](https://cesium.com/learn/cesiumjs/ref-doc/TimeInterval.html) : Time interval when the Satellite Reference System is displayed, _default_ : the time interval of definition of the satellite.
+
+## Intrinsinc arguments
+
+These arguments can be used to build the Satellite Reference System object :
+
+**satellite** - [Satellite](Satellite) : The satellite of the reference system.
+
+**scale** - double : The scale to which the model (if it exists) must be, _default_ : 0.02;
+
+**maximumScale** - double : The maximum scale up to which the scale can go, _default_ : 1000000.
+
+**minimumPixelSize** - double : The minimum of pixels displayed on screen, _default_ : 200.
+
+## Other parameters
+
+**referencePosition** - [Reference](https://github.com/AnalyticalGraphicsInc/czml-writer/wiki/ReferenceValue) : The reference in position of the satellite to lock the reference system in the center of the satellite.
+
+**referenceOrientation** - [Reference](https://github.com/AnalyticalGraphicsInc/czml-writer/wiki/ReferenceValue) : The reference in orientation of the satellite, to have the reference system with the same orientation as the satellite.
+
+**referenceSystemModel** - [CzmlModel](CzmlModel) : The 3D model that represents the reference system.
+
+# Build
+
+These arguments can be used to build the abstract point on body object :
+
+* A [satellite](Satellite) :
+
+```java
+SatelliteReferenceSystem system = new SatelliteReferenceSystem(satellite);
+```
+
+* A [satellite](Satellite), a scale, a maximumScale, a minimumPixelSize :
+
+```java
+SatelliteReferenceSystem system = new SatelliteReferenceSystem(satellite, scale, maximumScale, minimumPixelSize);
+```
