Question [Q] GPS problem - strange missing GpsSocket

I've rooted & installed TitaniumBackup in the very first day, but somehow I've found missing gps-related(?) app.
also it seems that phone can't use GPS sats without a-gps. Many times I used GPS Test & GPS Status in the street -- it found some sats but used none.
Who know this app and how it affects gps function?
and where can I take apk to restore it?)

i use native ROW, just rooted
service test shows "GPS -- OK"
SNR - -15
