AWS::GroundStation::Config AntennaDownlinkDemodDecodeConfig

Provides information about how Amazon Ground Station should configure an antenna for downlink during a contact. Use an antenna downlink demod decode config in a mission profile to receive the downlink data that has been demodulated and decoded.

Syntax

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