Content of presentation• Existing Albanian National Geodetic Network• Measurment Compaining by NIMA 1994• Measurment Compaining by Univ. Wisconsin 1998• Measument Process to link with EUREF• ALBPOS Project• Conclusions

INIMA Field MeasurmensIt was carry out incolloboration with AmericanCartographic Agency(todayINIMA) at october 1994.The Purpose of this activitywas transformation ofNational Geodetic Networkinto the World System ofWGS 84.During this Field Compaingwere measured alltogether 35points, where 24 wereselected from the NationalTriangolation Network(10 points from First range ofit; 14 from second range;and 11 points were takenfrom the First class ofNational Liveling System).

The standard deviations in the coordinates of thosestations were of the range by 1-2 cm.Second Measurment Campaign withGPS (February 1998)It was carry out in colloboration with GeodeticDepartment of Civil Engineering Faculty / WisconsinUniversity.The objective of this activity was the connection ofAlbanian National Geodetic Network with InternationalReference System (ITRF).During this measurment Process were measured: Pointnr.: 8814 (Kamza), Point nr.6339 (Shkodra),and point12602 (Korça).

Septembre 1998 anotherMeasurment Campaign wasrealised by using GPS.The objective: Connection of ourGeodetic Network with theEuropian reference SystemETRS-89.The measurments were carry outin 8 stations.5 points (or stations) were fromNational Geodetic Network and3 of them from the GeodinamicNetwork.Those are known now as theEUREF –Stations.The Standart Deviations instation’s coordinates were of therange ± 2mm in plan dhe ±6 mm in hight.

Till to 2007• Various Measurment Campaigns.• Various Purposes or Objectives.• To much measurments...• Conclusions ???What’s s the answer? What was next?

ALBPOS(Albanian Positioning Satellite Service)• The achivments and lesson to be learned led us:1. to argue that a Satellite Network and System is a neccesary y and unicsolution to solve all our problems. This idea was support from the tEU viaEURALIUS Office(an EU project to support the legal Sysytem in Cadaster) inTirana, which supported and helped Albanian Institutions to go head hwiththis idea. The ALBPOS was named this project.The first step: An Understanding Memorandum between Albanian NationalGeographic Institute, Department of Geodesy of CEF, The Central Office ofProperty Registraton and the Geoscience Institute, were signed.• A technical project were set up for this purpose.• As the first activity of the project was determining destribution n and locationof recever stations , during the year 2008. (see the map in next page).

The following pages in albanaian languages are described the criterions which were adestribution and locations of the permanent stations.

Conclusions• Albania has realised before 2007 manymeasurment campaigns and projects, butuncoordinated and pure results .• The projects before some time have beenrepeated each other, which has couse theunusefull cost.• This project based even in the good will of theall institutios and arranged by law andgovernment decision, is going head and seemsto be profitable for all users and the basicsupport for various projects in Albania.
