1. Establishing of detailed network and situational measurements and height elements using the technique GPS/GNSS and RTK/RTN. 1.1. GPS/GNSS network project and design (detailed networks). 1.2.
Assumption detailed geodetic base by the combined method: • assuming 4 points of the network using the measurement method static GPS/GNSS • checking the total station and rangefinder testing
(determination of the prisim constant) • establishing a traverse between GPS points (electronic total station) by precise polygonization- minimum two points • joint study (adjustment) of the results of
the GPS measurements and polygonization. 1.3. Situational and altitude measurements GPS-RTK method • transformation local (instantaneous) coordinate system to national system at the points of the
network • detailed development of measurement results - preparation of a fragment of the base map by RTK/RTN method. 2. Leveling and gravimetric measurements in the base vertical network 2.1.
Leveling measurements in basic height network on the line leveling line between GPS points • clasical precise leveling measurements , method of satellite leveling. 2.2. Gravimetric measurement
gravimetric benchmarks of leveling lines with relative method 2.3. Calculation of orthometric and normal corrections - calculation of orthometric and normal heights benchmarks on the leveling line. 2.4. Determination of the undulations of the geoid from the ellipsoid and height anomalies on selected line benchmarks level and comparison with obligatory geoid (quasi-geoid) model - satellite leveling. Accuracy analysis of the leveling line. Leveling precise
trigonometric. 3. Completion of the final reports
