# AWS::GroundStation::Config DecodeConfig
<a name="aws-properties-groundstation-config-decodeconfig"></a>

 Defines decoding settings. 

## Syntax
<a name="aws-properties-groundstation-config-decodeconfig-syntax"></a>

To declare this entity in your Amazon CloudFormation template, use the following syntax:

### JSON
<a name="aws-properties-groundstation-config-decodeconfig-syntax.json"></a>

```
{
  "[UnvalidatedJSON](#cfn-groundstation-config-decodeconfig-unvalidatedjson)" : String
}
```

### YAML
<a name="aws-properties-groundstation-config-decodeconfig-syntax.yaml"></a>

```
  [UnvalidatedJSON](#cfn-groundstation-config-decodeconfig-unvalidatedjson): String
```

## Properties
<a name="aws-properties-groundstation-config-decodeconfig-properties"></a>

`UnvalidatedJSON`  <a name="cfn-groundstation-config-decodeconfig-unvalidatedjson"></a>
 The decoding settings are in JSON format and define a set of steps to perform to decode the data.   
*Required*: No  
*Type*: String  
*Pattern*: `^[{}\[\]:.,"0-9A-z\-_\s]{1,8192}$`  
*Update requires*: [No interruption](https://docs.amazonaws.cn/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

## Examples
<a name="aws-properties-groundstation-config-decodeconfig--examples"></a>

### Create a DecodeConfig
<a name="aws-properties-groundstation-config-decodeconfig--examples--Create_a_DecodeConfig"></a>

The following example creates a Ground Station `DecodeConfig`

#### JSON
<a name="aws-properties-groundstation-config-decodeconfig--examples--Create_a_DecodeConfig--json"></a>

```
