MEMORIU DETERMINARE PUNCTE GPS


Cuprins:



1.    Scopul lucrarii

2.    Control WGS '84

3.    Echipamente, metode de masurare, software



4.    Transformari de coordonate

5.    Conditii de efectuare a observatiilor 

6.    Inventar coordonate compensate puncte noi

7.    Schita vectorilor

8.    Raport procesare vectori

9.    Raport compensare retea

1.     Prezenta lucrare a fost executata in vederea determinarii coordonatelor in sistemul WGS-84 si in Proiectie  Stereografica 1970 pentru 6 puncte (codificate COLI0-COLI4,20000).


2.     Controlul WGS-84 a fost realizat prin legarea GPS a punctului de interes COLI0 cu punctul de ordinul 1 BUESTI din reteaua geodezica nationala.


3.     Echipamente, metode de masurare, software

Masuratorile GPS au fost efectuate cu receptoare Trimble R3, cu operare in frecventa  L1. La procesarea datelor au fost utilizate efemeride transmise (broadcast);

Observatiile efectuate s-au facut utilizand metoda statica;

Pentru procesarea observatiilor GPS si determinarea coordonatelor punctelor noi in sistemul WGS-84 a fost folosita aplicatia Trimble Business Center.


4.     Transformarile de coordonate din sistemul WGS-84 in planul Proiectiei Stereografice 1970 au fost efectuate prin intermediul unei transformari polinomiale (regresie), de gradul 7, cu 28 de parametrii.
