 Most surveyors today are aware that data acquisition, management, analysis, 
	presentation and controlling systems are becoming more elaborate and 
	automated. The International Federation of Surveyors (FIG) Commission 5 – 
	Positioning and Measurement, has been and remains an essential part of the 
	surveying community’s growth and development. During the past two decades, 
	Global Navigation Satellite Systems (GNSS) have and continue to play an 
	increasingly important role in positioning and navigation. FIG enhances this 
	development by facilitating GNSS sessions at their conferences, encouraging 
	GNSS research and education, and cooperating with sister organisations such 
	as the International Association of Geodesy (IAG) in the respective domain. 
	Additionally, FIG is also trying to integrate GNSS surveying as a base and 
	starting point for land administration as well as cadastral registration, 
	especially in developing countries regarding property evidence. This is one 
	of the major reasons why FIG is looking at cost-effective technologies and 
	techniques for enabling surveyors in developing countries to use the best 
	equipment at a reasonable price. This Technical Report is the 2nd edition of 
	Publication No. 49 and builds upon the original document released in 2010 
	with the help of Special Study Group “Cost-Effective GNSS” within the 
	Working Group 5.4 “GNSS”. In 2014 the Report was updated due to new 
	technical developments. As Chair of FIG Commission 5 – Positioning and 
	Measurement, I thank Dr. Neil Weston, National Geodetic Survey, USA and 
	Prof. Volker Schwieger, University of Stuttgart, Germany for their efforts 
	in compiling and updating this report.
