The lower frequency allows deeper penetration into the sea floor than high frequency signals, but with poorer resolution. It is very difficult to detect underwater pipeline by conventional method, such as echo sounding and sidescan sonar method. NORMAL RESISTIVITY Apparent resistivity of material.
This leads to 13 equations more than is Section or 12 if the station is not part of ULR4 solution. Our surveys can assist in the design and execution stages prior to Geophysical techniques for precision navigation at sea moves and the emplacement of offshore infrastructure such as hydrocarbon production facilities, pipeline routes, offshore wind farms and other civil engineering projects.
That is, the ITRF parameter should not exhibit any discontinuity over the entire time span of the geodetic observations. As a result, the ITRF quality will suffer from any network degradation over time because it is heavily dependent on the network configuration.

Geodetic markers are unambiguous reference points for which geodetic coordinates can be determined.
