This was demonstrated autonomously with the Mantas during experiments at McMillan Airfield (see section 4), and is anticipated as a semiautonomous operation for the ScanEagles in future experiments.
High-quality pyranometers and pyrgeometers with faster responses (<1 s) are now commercially available, and will be incorporated into future versions of the payloads and discussed in future manuscripts.
