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 this process be carried out with full awareness of these developments and their various aspects, so that our country will not have to suffer the consequences of a hasty decision, including waste of financial resources.
GPS is not an exception from the above rule, and therefore several considerations must be taken into account before its purchase, including its fitness for the goals and the required precision. It is hoped that the present paper will provide the colleagues in the field with help in analysis of different receivers’ characteristics. On the whole, it is only through acting according to a reasonable rule that one can make the right decision.
