No, runway 15/33 at KSYR is served by the following:
1) A traditional VOR approach (one either end)
2) A GPS/RNAV with LNAV minimums - this means that the GPS provides only lateral (runway centerline) guidance and therefore minimums are higher - these approaches can be flown by non WAAS-enabled, IFR certified GPS's.
3) A GPS/RNAV with LPV minimums - this means that the GPS provides both lateral and glideslope guidance and therefore lower minimums, much like an ILS. Those aircraft (including my Bonanza) equipped with a WAAS-enabled, IFR certified GPS can fly these approaches. However, these LPV approaches have been NOTAM'ed not authorized for several months now. I do not know exactly why.
Also, as you may know, runway 15/33 has been closed since September due to runway maintenance. It opens sometime early November.
