Downlink Demod/Decode Template

The AWS CloudFormation template named DownlinkDemodDecodeCustomerTemplate.yml is based on the Downlink Only Template from the previous section. It provides all the resources necessary for a single downlink stream that is demodulated and decoded by the AWS Ground Station service based on the settings you provide. You can download the template using the following AWS CLI command:

aws s3 cp s3://groundstation-customer-cf/DownlinkDemodDecodeCustomerTemplate.yml

The template can be viewed and downloaded in the console by navigating to the following URL in your browser:

https://s3.console.aws.amazon.com/s3/object/groundstation-customer-cf/DownlinkDemodDecodeCustomerTemplate.yml

The template can be specified directly in AWS CloudFormation by using the following link:

https://groundstation-customer-cf.s3-us-west-2.amazonaws.com/DownlinkDemodDecodeCustomerTemplate.yml

What resources does the template define?

The downlink demod/decode template does not define any new resources on top of those defined in the downlink only template. However, it does add a new property called antennaDownlinkDemodDecodeConfig in the antenna downlink config properties.

What changes should I make to the AWS CloudFormation template?

In addition to the changes mentioned in the downlink only template section, the demodulation and decoding settings in the template need to be modified to work with the modulation and encoding scheme of the satellite you want to downlink from. These settings are defined in the antennaDownlinkDemodDecodeConfig section of the antenna downlink config. For more information, see Antenna Downlink Demod Decode Config.
