    Opis:
    In the paper experimental investigations related with analysis of navigational precision of three chosen GNSS receivers are shown. Used receivers allow for measurement of navigational signals in following modes of operations: receiving signals from singlefrequency GPS system, dual-frequency GPS/GLONASS system, and receiving signals from GPS constellation with use of differential measurements. In the last mode the base station and mobile receiver were configured for transmitting/receiving differential corrections by pair of industry-grade radio modems. The most important features and configuration of navigational receivers for conducted experiment are presented. Afterward the features of computer program designed especially for simultaneous acquisition, analysis of quality parameters and archiving of navigational signals are shown. The results of conducted investigations are also shown. For each of the receivers quantity and quality parameters such as maximum and minimum numbers of visible satellites and DOP (dilution of precision) parameters achieved during the experiment are given.

    Opis:
    In recent years, the Global Navigation Satellite System (GNSS) has been widely applied in surveying and mapping. Currently, in Vietnam, dual-frequency GNSS receivers are quite extensively applied with the real-time kinematic (RTK) measurement technique using a continuously operating reference station network. However, high-accuracy GNSS receivers are often expensive, sometimes not meeting the needs of users for specific applications. This research develops two types of low-cost highprecision GNSS receivers for RTK positioning for different purposes. First, the millimeter precision GNSS receiver used in real-time displacement monitoring is based on Trimble's BD970 mainboard technology and some other modules. These components are interconnected according to a standard design scheme and assembled in an enclosure to form a GNSS receiver. In addition, a GNSS data transmission in the National Marine Electronics Association standard format by Networked Transport of Radio Technical Commission for Maritime Services via Internet Protocol (NTRIP) has been designed and developed. The GNSS receiver after development is loaded with program code written in the C# programming language, using the Arduino programming tool. Second, the GNSS receivers have the centimeter accuracy for RTK positioning used in surveying and mapping based on U-blox's mainboard technology and some other modules. These modules are also connected together according to a standard design scheme and assembled in an enclosure to form a complete GNSS receiver. The evaluation results show that the designed and developed GNSS receivers completely meet the requirements of surveying and mapping in coal mines in Vietnam, such as real-time monitoring of landslides, surveying and topographical mapping and other surveying works to serve the mining process.

    Opis:
    With Galileo, the European GNSS (Global Navigation Satellite System) starting early services in 2015, open-area-testing of applications which use the new positioning system gets more and more important. This contribution gives an overview on existing test sites like railGATE, automotiveGATE and seaGATE, it highlights the latest addition for dynamic calibration with geodetic precision and finally describes the testing regime of the BONUS project ANCHOR, where multiple test sites are used for maximum benefit in a maritime application.
    Wraz z systemem Galileo, europejskim systemem nawigacji satelitarnej GNSS, którego pierwsze usługi przewiduje się udostępnić w 2015 roku, coraz bardzie istotne staje się stworzenie warunków dla testowania aplikacji systemu w otwartym terenie. Te możliwości dają poligony railGATE, automotiveGATE oraz seaGATE, które opisano w artykule, zwracając szczególną uwagę na dynamiczne kalibrowanie urządzeń z geodezyjną dokładnością. Zwrócono również uwagę na specyfikę testów przewidzianych w projekcie ANCHOR realizowanym w ramach europejskiego programu BONUS. Przewiduje się w nich różne warunki pod kątem maksymalizacji zastosowań morskich.

    Opis:
    Currently (April 2016) uninterrupted information about a ship’s position can be obtained from specialized electronic position-fixing systems, in particular, Satellite Navigation Systems (SNSs) such as GPS and GLONASS and Satellite Based Augmentation Systems (SBASs) such as EGNOS or WAAS. The generic name given to all the above mentioned systems is Global Navigation Satellite Systems (GNSS). Many models, designed for the ship’s bridge and provided by about a dozen manufacturers, are available on the world market. In Europe, one of the most comprehensive sources of knowledge on the global GNSS market is a report published, on average, every 15 months by the European GNSS Agency GSA. Another receiver survey is published each year in the January number of the magazine “GPS World”. The detailed analysis of market report and receiver survey, possible use of EGNOS and Galileo in the maritime market, and different maritime applications of GNSS equipment are described in this paper.
