Hi,
SD pseudo ILS  works with the runway threshold coordinates,giving a 50ft too low 3° vertical trajectory.
As we pass over runway threshold at 50ft,the touch-down point is 300 meters ahead,at the approximative
place we see tire marks on concrete runways.Abeam the glide path antenna.
Is-it not conceivable to make guidance towards the touch-down point coordinates in place of threshold ones?

Given that Pseudo ILS disables the glideslope at 500’ agl, why does it matter? What about offset ILS, does it cope with that?

It is not a substitute for a proper instrument procedure with the proper equipment, be it ILS or GNSS, and trying to use it like one is folly. SD is a VFR tool. 

IMHO of course.
