Unfortunately, SkySat Data isn't a part of E&R Subscriptions. Therefore, if you wish to get access to SkySat Data- it would need to be purchased.
Tasking Dashboard (TaDa) is a new user interface that allows customers to request SkySat collections. We can not provision access to TaDa for E&R Users.
If you wish to get access to SkySat Data and TaDa, please contact us via: https://www.planet.com/contact-sales/
