<br />CONTROL NETWORK USING GPS TECHNIQUES WITH ELLIPSOID
<br />HEIGHTS IN THE CCS 83 EPOCH 2017.50 SYSTEM ZONE III
<br />(2 -CM LOCAL AND NETWORK ACCURACY STANDARD) AND
<br />ORTHOMETRIC HEIGHTS IN THE NAVD 88 SYSTEM
<br />(GNSS-DERIVED, 2 CM LOCAL STANDARD) USING THE
<br />NATIONAL GEODETIC SURVEY GEOID 18 (CONUS) MODEL TO
<br />SUPPORT TRANSPORTATION PROJECTS ON CALIFORNIA STATE
