Volume 16, Issue 64 , February 2008, , Pages 49-53

Abstract
  In this paper, different methods of determining submarine position including LBL, SBL, USBL, GIB and a combination of them are presented and their advantages, disadvantages and applications of each are separately presented. Next, the proper system is presented according to the environmental conditions ...  Read More

The Necessity of National Positioning Systems as Complementary to Foreign Satellite Positioning Systems during Peacetime and Substitute in Crisis

Alireza Azmoodeh Ardalan; Mohammad Edrisian

Volume 15, Issue 57 , May 2006, , Pages 34-41

Abstract
  Considering the importance of position determination the and ease of using satellite methods in determining position, today global positioning systems such as GPS have become widely used in everyday life and military applications. The point that is generally forgotten when using these satellite systems ...  Read More

Hydrographic Information System

Alireza Azmudeh Ardalan; Kamyar Shoja'ei

Volume 13, Issue 51 , November 2004, , Pages 32-35

Abstract
  The use of marine data and information and depth measurement are among the technical requirements of major and minor decision making by the government and private sectors of the country. To use this information, which is increasing day by day in great quantities, and to use different information layers, ...  Read More

Introduction to GPS

Alireza Azmudeh Ardalan

Volume 3, Issue 11 , November 1994, , Pages 4-11

Abstract
  GPS (or Global Positioning System) is a NAVATAR (or Navigation System Using Time and Distance). This system is being developed by the U.S. Department of Defense. The creation of this system has begun since 1973 by combining the U.S. Air and Navy Forces’ projects. The plan of these two projects ...  Read More

Revision of Coverage Maps and Advantages of Exploiting Satellite Images

Alireza Azmudeh Ardalaan

Volume 2, Issue 7 , August 1993, , Pages 35-41

Abstract
  Map is the basis of all decisions and plans of development, and the need for its availability and preparation is not questioned by anyone. One of the main problems of our country is the lack of access to new and up-to-date coverage maps from all over the country. Coverage maps are a set of overlapping ...  Read More

Designing Geographic Information System's Section of Contact With User

Alireza Azmudeh Ardalaan

Volume 2, Issue 8 , February 1993, , Pages 27-27

Abstract
  The Geographic Information System (GIS) includes a set of spatial and non-spatial data that is presented based on specific analyses. In designing the mutual communication of such systems with the user, it is necessary to observe various principles in the use of maps, tables and verbal logs. Due to the ...  Read More

A Few Points on Correct Utilization of the Least Squares Methods

Alireza Azmudeh Ardalaan

Volume 2, Issue 5 , August 1992, , Pages 20-29

Abstract
  Today, all surveyors know that it is not possible to measure a length or angle without error. To establish mathematical relations governing observations, it is necessary to perform adjustment. One of the available methods for distributing errors is the least squares method. Unfortunately, many colleagues ...  Read More

Satellite Images Serving the Extinguishment of Fire in Kuwait Oil Wells

Alireza Azmudeh Ardalaan

Volume 1, Issue 4 , May 1992, , Pages 4-5

Abstract
  Landsat's recent images from Kuwait suggest that firefighting teams are ahead of the determined schedule. At the beginning of firefighting operations on burning oil-wells, oil-fire experts estimated the time needed for full control of wells’ fire to be five years. According to recent Landsat imaging, ...  Read More

A Discussion on Automation of Levelling

Alireza Azmudeh Ardalaan

Volume 2, Issue 6 , February 1992, , Pages 41-43

Abstract
  The basis of this new semi-automatic levelling method is to replace active mires with a linear measuring system instead of ordinary mires. These mires have a movable target that is fitted along the axis of vision by levelling operator and with the help of a wireless control system. The target place can ...  Read More

Selection of GPS Receiver for Surveying Goals

Alireza Azmudeh Ardalan

Volume 1, Issue 3 , August 1991, , Pages 24-32

Abstract
  Just as avoiding modern technology seems wrong, hasty and unaware attitude toward purchase of all types of advanced goods is also to be taken as unwise. It is obvious that surveying must adapt to the latest advancements and equip itself with progressive methods and tools, but it might be better that ...  Read More

Estimation of the Costs of GPS-Based Surveying

Alireza Azmudeh Ardalaan

Volume 1, Issue 3 , August 1991, , Pages 40-43

Abstract
  The Global Positioning System (GPS) currently has seven active satellites of block 2 and six satellites left over from the block, and provides the possibility of good geodetic positioning for several hours every day (with more precision than what is possible with today's surveying tools.). Since GPS ...  Read More

Determination of Orthometric Height Using GPS

Alireza Azmudeh Ardalaan

Volume 1, Issue 1 , May 1990, , Pages 38-43

Abstract
  With GPS, the plane coordinates can be determined 10 to 20 times more accurate than traditional (classical) methods. This high level of accuracy can be achieved by one or two hours of observation and without any need for direct view between the stations. Because of this, GPS is becoming the only means ...  Read More

The Role of Satellite Images in Estimation of Losses Caused by Natural Incidents

Alireza Azmudeh Ardalaan

Volume 1, Issue 2 , February 1990, , Pages 30-31

Abstract
  TM sensor information is a peerless tool for ecologists, including in the estimation of the damage caused by fire. The two pictures that can be seen show the US Yellowstone National Park. These images result from the combination of data for band 7 (within the range of the red spectrum), 5 (within the ...  Read More
