# Set up and configure Amazon S3
<a name="dataflows.s3-configuration"></a>

 You can utilize a Amazon S3 bucket to receive your downlink signals using AWS Ground Station. To create the destination *s3-recording-config*, you must be able to specify a Amazon S3 bucket and an IAM role which authorizes AWS Ground Station to write files to the bucket. 

 See [Amazon S3 Recording Config](how-it-works.config.md#how-it-works.config-s3-recording) for restrictions on the Amazon S3 bucket, IAM role, or AWS Ground Station config creation.
