From my recollection, Maestro, Compas and pFAST were all 'sequencing' tools, whereas NATS FAST was/is a 'spacing' tool. Subtle differences in their design and intentions of how to aid controllers (or not
).
Maestro developed by Sofreavia in France, sold to the French ATC and also Oz plus I think elesewhere as part of bundled packages...the French have a way of doing this....
Compas developed by DFS for themselves.
NATS FAST developed by NATS for NATS at Hurn.
I think all of these products have been displayed at various conferences ATCA / Maastricht etc...
Not a controller so I couldn't / wouldn't comment on any of their effectiveness....
