   en.wikipedia.org/wiki/GNSS_applications

   Surveying — Survey-Grade GNSS receivers can be used to position survey markers, buildings, and road construction. [6] These units use the signal from both the L1 and L2 GPS frequencies. Even though the L2 code data are encrypted , the signal's carrier wave enables correction of some ionospheric errors .

4. Real-time kinematic positioning - Wikipedia
