Opis:
In detailed silvicultural planning, good knowledge of the internal situation (e.q. placement of advanced regeneration) in stand survey units is necessary. Information gathered in the framework of regular forest survey is not sufficient, specifically when natural stand regeneration is planned. The application of GPS is a practical, inexpensive, quick to operate technology of collecting information required for silvicultural planning and positioning spatial elements of a cutting system. As silviculture needs do not require such a high accuracy as in the case of positioning of stand survey units, it seems that the application of tourist−class GPS receivers is an optimum solution. This class equipment is inexpensive and easy to operate. The knowledge about possibilities which GPS receiver provides on the one hand and the awareness of limitations that forest environment creates for GPS measurements helps make a reliable draft of a stand's internal situation.

Opis:
Satellite measurement techniques have been used for many years in different types of human activity, including work related to staking out and making use of rail infrastructure. First and foremost, satellite techniques are applied to determine the tramway track course and to analyse the changes of its position during its operation. This paper proposes using the least squares with conditional equations method, known in geodesy (LSce). When applied, this method will allow for improvement of the final determination accuracy. This paper presents a simplified solution to the LSce alignment problem. The simplification involves replacement of the parameter binding equations with equivalent observational equations with properly selected weights. The results obtained with such a solution were demonstrated with a randomly selected section of a tramway track in Gdańsk. The article presents the theoretical foundations of the test method, the experiment organisation and the results obtained with MathCad Prime 3.0 software. It also presents the outcome of a study associated with the execution of the project No POIR.04.01.01-00-0017/17 entitled “Developing an innovative method of precision determination of a rail vehicle trajectory” executed by a consortium of the Gdańsk University of Technology and Gdynia Maritime University.

Opis:
Modern technical ship systems very often use information and communication technologies. One of the basic requirements of these systems is ensuring time synchronization that aim is to coordinate clocks of all devices working in a computer network. This requirement results from, among others, the necessity to log events with a unified timestamp. To achieve this goal, most frequently expensive time servers are used. This article presents an easy method of time synchronization, which can serve as a reserve or alternative solution to the methods currently used. That is why a proprietary software has been developed, allowing to expand the functionality of a PC so that it can operate as a time server. A time reference in proposed solution would be provided by a GPS receiver. The developed application allows, with the use of the NMEA protocol, to synchronize the current time with the GPS receiver and then, with the help of the SNTP protocol, to distribute it to all network devices operating on the ship.

Currently (July 2014) an uninterrupted information about the ship’s position can be obtained from specialized electronic position-fixing systems, in particular, Satellite Navigation Systems (SNSs) as GSP and GLONASS and Satellite Based Augmentation Systems (SBASs) as EGNOS or WAAS. On each ship’s bridge one GPS stationary receiver is installed at least but on many ships there are two or even more GPS receivers. Nowadays, several hundred different end-user products and broad/chipset/modules are available on the world market, however for ship’s bridge several dozen models provided by a dozen or so manufacturers are designed only. In this paper 309 GPS receivers, 47 different models of 12 manufacturers installed on 188 ships of different types and with different lengths were taken into account. The relations between the type and the length of the ship, the number of the GPS receivers installed on one ship, the manufacturers and the models the most frequently used are presented.

Opis:
Signals from Global Navigation Satellite Systems are the primary source for Position, Navigation and Time (PNT) information onboard any vessel today. As these signals are prone to interference, a maritime backup system is needed to provide reliable PNT data, R(anging)-Mode is such a system. It utilizes existing maritime radio beacons or base stations of the Automatic Identification System (AIS) by adding ranging components to the legacy signals. The first modified radio beacons transmit medium frequency (MF) R-Mode signals in northern Germany. This paper has described the current state of the authors’ research and development activities at the receiver level for MF R-Mode signals. The receiver platform has been introduced, which was based on off-theshelf components and the implemented algorithms for distance estimation have been explained. Furthermore, the results of the first ranging measurements have been presented, which have shown the general suitability of the R-Mode technology as a source for maritime positioning and timing data.

Opis:
Nowadays on the ship’s bridge two or even more GPS receivers are installed. As in the major cases the coordinates of the position obtained from these receivers differ the following questions can be posed – what is the cause of this divergence, which receiver in the first must be taken into account etc. Based on information published in annual GPS and GNSS receiver survey it was estimated the percentage of GPS receivers designed for marine and/or navigation users. The measurements of GPS position based on the four different stationary GPS receivers were realized in the laboratory of Gdynia Maritime University in Poland in the summer 2012. The coordinates of the position of all these receivers were registered at the same time. The measurements in mode 3D were made for different input data, the same for all receivers. The distances between the individual unit’s antenna were considered also. Next measurements in mode 3D also were realized on two ships in different European ports. Additional measurements were made in mode 2D with three receivers for different their’s antenna heights. The results showed that the GPS position accuracy depends on the type of the receiver and its technical parameters particularly.

Opis:
New shipping routes are emerging as a result of iceberg melting in polar regions, allowing for more efficient transport of people and goods. Opening of the Northwest Passage, the maritime route connecting Pacific Ocean with Atlantic Ocean through Arctic region, is considered such a development. The increasing transport exploitation of the Northwest Passage requires the quality assessment of maritime navigation aids for compliance with the established requirements. Here we contribute to the subject with addressing the polar commercial-grade GPS positioning performance in the Northwest Passage in the extreme positioning environment conditions during the massive 2003 space weather storm, a space weather event similar to the Carrington Storm of 1859, the largest space weather event recorded. The GPS positioning environment in the Northwest Passage during the Carrington-like storm in 2003 was reconstructed through the GNSS SDR receiver-post processing of the experimental GPS observations. The raw GPS dual-frequency pseudoranges and navigation messages were collected at the International GNSS Service (IGS) reference station at Ulukhaktok, Victoria Island, Canada. Pseudorange processing and GPS position estimation were performed in three scenarios of pre-mitigation of the ionospheric effects, known as the single major contributor GPS positioning error: (i) no corrections applied, (ii) Klobuchar-based corrected GPS positioning, and (iii) dual-frequency corrected GPS positioning. Resulting GPS positioning error vectors were derived as positioning error residuals from the known reference station position. Statistical properties of the northing, easting, and vertical components of the GPS positioning error vector were analyzed with a software developed in the R environment for statistical computing to select suitable methods for the GPS positioning error prediction model development. The analysis also identified the most suitable theoretical fit for experimental statistical distributions to assist the model development. Finally, two competitive GPS positioning error prediction models were developed, based on the exponential smoothing (reference) and the generalized regression neural networks (GRNN) (alternative) methods. Their properties were assessed to recommend their use as mitigation methods for adverse massive space weather effects in polar regions.

Opis:
The general accessibility and high accuracy of GPS caused that for a dozen or so years it is applied commonly, not only in marine navigation. We can ascertain that in this regard there exists the monopoly. However, now it is apparently that this system can be easily disturbed, what testify numerous reports. The problem has been treated as troubles in land navigation, however nowadays became every-day reality on coastal waters as well, especially on the Mediterranean and Black Seas and Persian Gulf. Officers who survived this tell that the first impulse in such situation is to verify GPS receiver, regardless of the situation around the ship. The concentration of the officer’s attention on the GPS receiver, especially on coastal waters creates the threat for the ship, however in this situation appear other threats which many officers does not associate with GPS. Usually on the present ship GPS receiver is not only the source of positioning information. It is a source of information for many other devices, so inappropriate work of it generates problems with many other processes on the ship. Today question is who on the bridge can notice GPS problems and how? There are receivers which do not inform about the problem, or present not realistic data. Sometimes only ECDIS picture shows some abnormality, for example still the same position while ship is under the way. On the paper the analysis of possibly aspects of the problem is discussed. Presented analysis goes to the conclusion that should be prepared some procedure how to proceed in case of the lack of GPS signals, as well as the watch officer should be prepared to act in such situation. This is a task for marine academies.

Opis:
In the past it was usual to exert a huge effort in the design, simulation, and the real time implementation of the complicated electronic and communication systems, like GNSS receivers. The complexity of the system algorithms combined with the complexity of the available tools created a system that is difficult to track down for debugging or for redesign. So, the simulation and educational tools was different from the prototyping tools. In this paper the parallel search acquisition phase of a GPS receiver was simulated and implemented on FPGA using the same platform and through a graphical programming language. So this paper introduces the fruit of integrating the prototyping tools with the simulation tools as a single platform through which the complicated electronic systems can be simulated and prototyped.
