Alpha Numeric Waypoints

Can anyone tell me what a waypoint with 3 alphas and 6 numbers represents? Such as ACY176027.

This is a position relative to a VOR navaid. For your example, the waypoint would be 27nm from the ACY VOR, on the 176° radial

See VHF omnidirectional range - Wikipedia for more info on VORs.

Thank you! I tried to insert that waypoint into my flight Sim FMS but it did not recognize it. I probably need to create that point within the FMS.
