GPS in Surveying - Part II
Volume 2, Issue 5 , August 1992, , Pages 14-18
Abstract
Space-Based Positioning was begun and followed up since 1960 by the U.S. government and NASA. One of these early and highly successful systems of positioning was the Transit satellte. This satellite, since its launch in 1967 for commercial aims, has also gained applications in surveying and geodesy, ... Read MoreGPS in Surveying

Abstract
Positioning based on space started in early 1960 and followed up by the United States and NASA. One of these early and very successful systems of positioning was the TRANSIT Satellite. Since its launch in 1967 for commercial purposes, this satellite has gained many applications in surveying and geodesy, ... Read MoreRole of Electromagnetic Waves and Electronics in Surveying and Geodesy - Part IV
Volume 1, Issue 4 , May 1992, , Pages 52-55
Abstract
A) In measuring distance by new rangefinders the following methods are used: 1) Phase comparison method 2) Pulse method (measuring travel time of a pulse until it returns) 3) Interferometry method These methods all depend on the fact that the speed of travel of electromagnetic waves is in the order of ...

Volume 1, Issue 3 , August 1991, , Pages 36-39
Abstract
We have seen the definition of electromagnetic waves in previous papers. Parts of the spectrum of these waves used in new surveying and geodetic equipment include: 1) Infrared radiation 2) Visible light 3) Microwave All of these three are used in new tools to measure lengths and distances.

Volume 1, Issue 1 , May 1990, , Pages 4-15
Abstract
The history of maps and surveying in the world and in Iran is scattered and written in different perspectives, which should be gradually developed and completed by the efforts of the experts. The following two articles by Dr. Hasan Shamsii are efforts in this regard. Professor Shamsii is one of the veterans ... Read MoreHistory of Surveying in the World
Volume 1, Issue 1 , May 1990, , Pages 4-16
Abstract
Most likely, the surveying has had its roots in ancient Egypt. The Great Pyramid of Kofu the second Pharaoh from the fourth dynasty of Egypt in the old city of Giza, which was built around 2700 BC, is so precisely quadrangular and fully justified according to the four main directions of compass, that ...

Volume 1, Issue 1 , May 1990, , Pages 58-64
Abstract
During the Second World War, radar was used to detect objects or targets and to determine their distance and direction (or azimuth). The radar performs its task by sending extremely short waves (called microwaves) to a target and their return from the target to the sender. The total traveling time ...
