Abstract

Primjena globalnih navigacijskih satelitskih sustava (GNSS) postala je nezaobilazna u današnjoj svakodnevnici te je proteklih godina došlo do modernizacije navedenih. U ovom radu dan je uvid trenutačnog statusa i planiranog razvoja dvaju globalnih navigacijskih sustava, GPS-a i GLONASS-a. Opisan je format RINEX bez kojega bi cijela funkcionalnost i rad sustava bili nemogući. Objašnjene su vrijednosti DOP-a kao mjerila za kvalitetu konfiguracije satelita. Opisan je rad CROPOS-a i njegovih servisa budući da čini temelj za geodetske i kartografske djelatnosti te u isto vrijeme pruža podatke za izmjeru, kartiranje, navigaciju i znanstvena istraživanja. U svrhu planiranja opažanja primijenjena je aplikacija Trimble Planning čiji su rezultati detaljno objašnjeni. Izmjera geodetske mikromreže obavljena je u obliku geodetskog četverokuta na području grada Zagreba metodom relativnoga statičkog pozicioniranja. Obrada mjerenja i izjednačenje mikromreže provedeni su pomoću dva neovisna pristupa. Prvi način obavljen je primjenom softvera MAGNET Tools koji je proizvod tvrtke Topcon. Drugi pristup obavljen je pomoću softvera WaSoft u kojem su izjednačene bazne linije i softvera JAG3D u kojem je izjednačena geodetska mikromreža.

Abstract (english)

The use of Global Navigation Satellite Systems (GNSS) has become indispensable in today's everyday life. In recent years, the systems have been modernized. This paper provides insight into the current state and planned development of two global navigation systems, GPS and GLONASS. The RINEX format is described, without which the entire cooperation and operation of the system would be impossible. The value of DOP as criterion for satellite configuration quality is explaned. The work of CROPOS and its services is described since it forms the basis for geodetic and cartographic activities and at the same time provides data for surveying, mapping, navigation and scientific research. For the purpose of planning observations, the Trimble Planning application was used, the results of which are explained in detail. The geodetic microgrid was measured in the form of a geodetic quadrangle in the area of the city of Zagreb using the method of relative static positioning. Measurement processing and network adjustment were using two independent approaches. The first method was performed using the software MAGNET Tools, which is a product of the company Topcon. The second approach was performed using the WaSoft software in which the baselines were adjusted and the JAG3D software in which the geodetic grid was adjusted.
