Abstrak Penggunaan receiver GPS RTK (Real Time Kinematic) pada metode ekstraterestrial untuk penentuan posisi titik saat ini sudah banyak diterapkan. Penelitian ini bertujuan mengkaji sampai sejauh mana ketelitian posisi titik yang diperoleh dari hasil pengukuran secara ekstraterestrial menggunakan GPS RTK untuk pemetaan bidang-bidang tanah berikut kekurangan dan kelebihannya. Dari hasil pengukuran didapat ketelitian rata-rata hasil pengukuran posisi titik menggunakan GPS RTK dibandingkan dengan menggunakan alat ETS (Electronic Total Station) adalah sebesar 0,214 m sehingga dapat diterapkan untuk pembuatan peta skala 1 : 500. Untuk daerah yang terbuka, pengukuran bidang tanah menggunakan GPS RTK memerlukan waktu dua kali lebih cepat dibandingkan dengan ETS. Walaupun GPS RTK mempunyai keunggulan dalam hal efisiensi proses pengukuran di lapangan sehingga dapat mempersingkat waktu pengukuran, akan tetapi memiliki kekurangan dalam hal ketelitian data terutama pada area pengukuran yang tertutup. Kata kunci: GPS RTK, ETS, posisi titik, ekstraterestrial.   Abstract The use of RTK GPS receiver (Real Time Kinematic) on extraterrestrial method for point positioning h widely applied. The purpose of this study is to examine the point position accuracy obtained from the measurements using GPS RTK for extraterrestrial mapping plots, including its advantages and disadvantages. Measurement accuracy of the results obtained from the average measurement point positioning using GPS RTK compared using the ETS tool is equal to 0.214 m, so that it can be applied for map making of scale 1: 500. For open areas, field measurements using GPS RTK can be performed by two times faster than using ETS. Although GPS RTK has advantages in terms of measurements process efficiency in the field so as to shorten the time of measurement, but has shortcomings in terms of accuracy of the data, especially in an enclosed area measuring. Keywords: GPS RTK , ETS, point position, extraterrestrial.

Real-time kinematic (RTK) technique is important for mapping applications requiring short measure time, the distance between rover and base station, and high accuracy. There are several RTK methods used today such as the traditional RTK, long base RTK (LBRTK), network RTK (NRTK), and precise point positioning RTK (PPP-RTK). NRTK and LBRTK are popular with the advantage of the distance, the time, and accuracy. In the present study, the NRTK and LBRTK measurements were compared in terms of accuracy and distance in a test network with 6 sites that was established between 5 and 60 km. Repetitive NRTK and LBRTK measurements were performed on 6 different days in 2015-2017-2018 and additionally 4 campaigns of repetitive static measurements were carried out in this test network. The results of NRTK and LBRTK methods were examined and compared with all relevant aspects by considering the results of the static measurements as real coordinates. The study results showed that the LBRTK and NRTK methods yielded similar results at base lengths up to 40 km with the differences less than 3 cm horizontally and 4 cm vertically.

A real-time kinematic (RTK) global positioning system (GPS) has been identified for potentially being used as a ground-truth sensor for testing robotic rovers for planetary exploration. A series of environmental tests needs to be performed in order to validate the performance of the sensor at hand before being used as a ground-truth system. This paper focuses on the performance evaluation of the RTK GPS at Axel Heiberg Island Canadian Space Agency’s Analogue Research Network (CARN) site. This is one of the officially recognized terrestrial analogues, that is places on Earth that approximate the geological, environmental and putative biological conditions on Mars and other planetary bodies (Hipkin et al.). The challenge lies in the use of the equipment at Arctic latitudes. The results show that the system performed according to specifications even in this challenging environment.

Accuracy and total design and implementation cost of the GPS framework determine the viability of GPS based projects. As the greater part of the advanced framework including telemetry, IoT, Cloud, and AUTOSAR frameworks use GPS to get exact outcomes, finding a software-controlled error correction becomes important. With the execution of open source library such as RTKLIB will help in controlling and revising GPS blunders. The project utilizes the RTKLIB along with two stations for better accuracy. The RTK-GPS framework works under Linux environment, which is embedded in the Beagleboard. The communication between the GPS system is set up utilizing both serial communication protocol and TCP/IP suite. To get high precision inside the network, two GPS modules are utilized. One of them will be mounted on the rover and another GPS is the base station of the setup. Both the GPS will have a double radio wire setup to increase the reception level to reduce the noise and get centimeter-level precision. For long-range communication, Rover utilizes Wi-Fi with TCP/IP stack protocol. In this research paper, setup is intended to accomplish the centimeter level precision through libraries in a Linux environment. The design will be set up and tried on a college campus under various conditions with different error parameters to acquire a low cost and centimeter level GPS accuracy.

Worldwide, the determination of the coordinates from a Global Navigation Satellite System (GNSS) survey (in Network Real Time Kinematic, Precise Point Positioning, or static mode) has been analysed in several scientific and technical applications. Many of those have been carried out to compare Precise Point Positioning (PPP), Network Real Time Kinematic (NRTK), and static modes’ solutions, usually, using the latter as the true or the most plausible solution. This approach is not always possible as the static mode solution depends on several parameters (baseline length, acquisition time, ionospheric, and tropospheric models, etc.) that must be considered to evaluate the accuracy of the method. This work aims to show the comparison among the GNSS survey methods mentioned above, using some benchmark points. The tests were carried out by comparing the survey methods in pairs to check their solutions congruence. The NRTK and the static solutions refer to a local GNSS CORS network’s analysis. The NRTK positioning has been obtained with different methods (VRS, FKP, NEA) and the PPP solution has been calculated with two different software (RTKLIB and CSRS-PPP). A statistical approach has been performed to check if the distribution frequencies of the coordinate’s residual belong to the normal distribution, for all pairs analysed. The results show that the hypothesis of a normal distribution is confirmed in most of the pairs and, specifically, the Static vs. NRTK pair seems to achieve the best congruence, while involving the PPP approach, pairs obtained with CSRS software achieve better congruence than those involving RTKLIB software.
