Gravimetry and geodesy division Gravimetry and geodesy division

 

Introduction:

The gravimetry section was established at the beginning of the work of the Geophysical Institute in the year 1336 AH and gradually expandedThis section has been created to provide a framework for applied research in the form of estimation and communication with organizations and other centersIn addition, it provides training for undergraduate students and prospecting in underground mines and reservoirs and exploring the geological structures of engineering projects site .

 

Goals and capabilities of the sector

The main objectives of this research are :

  • Development of first-degree and second-rate national networks
  • Measurement of Absolute Price across the country
  • Determine the base station of the country
  • Study of regional anomalies (isostatic)
  • Examine the delicate movements of the shell and faults
  • Determine the Earth's crust (geoid) of Iran
  • Micro-gravity studies and its engineering applications

The main objectives of this training are :

  • Providing background to students' theoretical learning
  • Assistance in field operations related to student research

The main goals of the activities of this department in relation to other organizations and centers are :

  • Consultation in the design of geometrical studies of geophysical projects of the country's scientific and industrial centers
  • Collaborating on the implementation of cost-effective applied research projects (described below)

The following are the main fields of activity :

  • The study of expensive anomalies
  • Study of underground caverns and location of salt domes
  • Participation in the search for underground reservoirs
  • Identification of zones, cavities, caves and karstic subsidence

Equipment (laboratory and field) of the granit section

  • CG5 Gravity Meter for measuring gravity with a precision of less than 0.005 milligrams
  • Gauge CG3M for measuring the accuracy of 0.005 milligrams
  • Gauge CG3 for measuring the accuracy of 0.100 milligrams
  •  Scania Gravity Meter  (GS 12) to measure gauge
  • Gauge Lacoste Ramberg Model G for measuring the accuracy of 0.01 milligrams
  • Lacoste Ramberg Model D for measuring accuracy of 0.001 milligrams
  • Computer facilities and advanced software for computing and modeling

 

Mapping devices available to measure the exact coordinates of stations :

  • GPS   dual-frequency Trimble model R7R8  

Three, including one R7 as Base and two R8 for the rover to the team Gravimetric isolated with relative accuracy ppm 1 + mm 5 and two keyboards ACU method Static Radio 35 watts with a range of up to harvest by RTK to measure Coordinate points

  • The Total Station Trimble Camera of Sweden, Model 5601 with the following specifications :
  • Secure reader with a precision of 1 second (0.3 milliseconds)
  • Equipped with two-axis electronic capacitor with a precision of 1.5 seconds
  • It has a motorized system
  • Carefully measure the distance in less than two seconds ppm 1 + mm 1
  • The ability to use ACU keyboards (by switching the keyboard from GPS to Total Station and vice versa can be easily done)
  • 1-watt radio for robotic or singleOne Man System )
  • With automatic target recognition systems that target search device (charter) has been activated and is then locked to any moving target, Total station will also move .

This camera can be used for surveying topographic data in near zones for any distance-intensive gravimetric station (stacking with static GPS over long distances.
