Abstract

V projekti nalogi sem najprej opisal različne globalne navigacijske satelitske sisteme. Kasneje sem povzel katere metode GNSS izmere vse poznamo, opisal sem tudi slovensko omrežje SIGNAL in pa globalno omrežje IGS. V nadaljevanju sem primerjal dva odprtokodna programa (Trimble GNSS Planning Online in Topcon Occupation Planning) za GNSS planiranje in prikazal kako poteka samo planiranje. Oba programa nam lahko rezultate planiranja podata grafično, točne vrednosti števila satelitov in pa DOP vrednosti pa nam lahko prikaže le program Topcon. V nadaljevanju sem se lotil še vrednostne analize programov, kjer sem v primerjavo vključil še en program, ki pa ni brezplačen in ugotovil, da je ravno ta program najboljši po lastnostih, po relativni vrednosti pa je najbolj optimalna izbira za planiranje GNSS izmere program Topcon. Za tem sem prikazal kako je potekala sama terenska izmera, kjer sem opravil tri meritve z GNSS sprejemnikom znamke Topcon Hiper V, nato podatke obdelal z programom Magnet Office Tools in jih primerjal z rezultati planiranja. Ugotovil sem, da so se DOP vrednosti v programu za planiranje izkazale za malenkost manjše kot pa v rezultatih s terena, kar pa je normalno, saj programi za planiranje predvidijo idealne razmere, ki pa se na terenu pojavijo redkeje. Pri dveh meritvah je prišlo do odstopanj v številu satelitov, s katerimi se je GNSS sprejemnik povezal, DOP faktorji pa so ostali skoraj enaki, kar pa nam pove, da DOP vrednosti niso odvisne samo od števila satelitov, ampak predvsem od razporeditve le teh na nebu.

Secondary abstract:	In the project work I first described the various global navigation satellite systems. I later summed up all the GNSS surveying methods we know, described the Slovenian network named SIGNAL and the global network named IGS. Afterwards I compared the two open source programs (Trimble GNSS Planning Online and Topcon Occupation Planning) for GNSS planning and showed how the planning is done. Both programs are capable of displaying graphical results, as well as giving us the exact number of satellites. The TOPCON program is the only one capable of giving us the DOP values. Furthermore I tackled the value analysis of the programs, where I have taken into account another program that is not free of use, and I realized that this program was the best in the compared characteristics, whereas for the relative value the most optimal choice for GNSS survey planning would be the program Topcon. After the comparison, I showed how the terrain surveying took place, where I have made three measurements with the Topcon Hiper V GNSS receiver and later processed the data itself with the software Magnet Office Tools and compared them with the results of planning. I concluded that the DOP values in the program for planning were slightly lower than the field results, which is normal, because the planning programs take into account the ideal conditions, which appear less frequently in the field. The two measurements resulted with discrepancies in the number of satellites to which the GNSS receiver was connected, but the DOP factors have remained almost the same, which tells us that the DOP values depend not only on the number of satellites, but primarily on their distribution in the sky.
