4 Introduction The Military Geographical Institute (IGM), the Ecuadorian institution in charge of cartography, has as a main objective to establish a modern Geodetic Reference Frame compatible with modern measurement techniques such as Global Navigation Satellite Systems (GPS, GLONASS and Galileo).

5 With this objective in mind, IGM of Ecuador, in coordination with SIRGAS, has implemented REGME, according to IGS standards.

6 REGME is currently composed of 8 stations: QUI1 (Quito) GPS (IGS station) RIOP (Riobamba) GPS (IGS station) GLPS (Pto. Ayora) GPS (IGS station) GPS+GLONASS PTEC (Portoviejo) GPS+GLONASS GYEC (Guayaquil)GPS+GLONASS CUEC (Cuenca) GPS+GLONASS GPS+GLONASS LJEC (Loja) ESMR (Esmeraldas) GPS

7 Future stations in 2009 and 2010 IGM, in collaboration with Geophysical Institute of Ecuador, has planned to install 6 station more.

8 REGME and SIRGAS-CON REGME stations are also part of the continental network SIRGAS-CON and are officially processed by the German Geodetic Research Institute (DGFI) and the Brazilian Institute of Geography and Statistics (IBGE).

9 Site selection Consideration: Safety Access to Internet Stability Free of obstructions

10 Site selection Additionally, a key feature of each site was to comply with a zero frequency external interference that could degrade the GPS signal quality, verified by a spectrum analyzer.

17 GNSS DATA PROCESSING CENTRE OF ECUADOR (CEPGE).

18 Introduction GNSS Data Processing Centre of Ecuador was created in CEPGE is equipped with the scientific Bernese software version 5.0, thanks to a cooperation agreement between the DGFI, the University of Bern, and the IGM.

19 CEPGE and SIRGAS At present, the CEPGE acts as a SIRGAS experimental processing centre since GPS week 1513 (January 4, 2009), within a year of training and strictly observance of the SIRGAS guidelines for processing, CEPGE is expected to become an official SIRGAS Analysis Center.

20 This centre processes 34 SIRGAS-CON stations and generates loosely constrained weekly solutions (sinex format) that are sent to SIRGAS for evaluation.
