“…When the station count increases, corrections are attained [15]. Many correction computing solutions are currently available, such as the VRS (virtual reference stations), MAC (Master Auxiliary Concept), PRS (pseudo reference stations), and FKP (Flächenkorrekturparameter) methods [14,16,17]. The VRS technique is currently the most popular and efficient method of transmitting corrections through a data link to the network users for RTK positioning.…”

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.

“…It has 158 control points all around Turkey and allows the GNSS receivers to obtain real-time coordinates of any point on the terrain which has open sky view for satellite transmissions [24]. The positioning accuracy of the real-time GNSS observations are below ±3 cm in horizontally and ±5 cm vertically while using this network [25][26].…”

P hotogrammetry has been widely used for acquiring field data, which has much more better spatial resolution than remote sensing. Also, close range aerial photogrammetry by using unmanned platforms is a new concept considering other techniques and methods. Using that technique is mainly based on the necessity for low-cost and less labor applications. Aim is to extract geo-referenced information of the interested objects and/or regions in a wide range of data diversity by automated processing with the help of stereo aerial imagery [1][2][3][4][5][6][7].Considering the aim and purpose, model from a UAV flight can procure accurate data in a wide range of small to large scaled projects (Fig. 1) [1,4]. In this concept, requirement and applications of UAV photogrammetry vary from agriculture to forestry, archeology, geology and even specific activities like measurement of the tree heights for monitoring the development of the forestland, soil displacement and such civil engineering applications [1][2][3][4][5][6]8].Nowadays, there are several types of those UAV platforms (fixed or rotary wings, etc.

“…Differential positioning technology can be divided into four types of algorithms according to the information used: position difference, pseudo-range difference, phase smooth pseudo-range difference or carrier phase difference [12][13][14]. The four differential positioning techniques work in a similar manner.…”

BeiDou navigation satellite system (BDS) is one of the four main types of global navigation satellite systems. The current system has been widely used by the military and by the aerospace, transportation, and marine fields, among others. However, challenges still remain in the BeiDou system, which requires rapid responses for delay-sensitive devices. A differential positioning algorithm called the data center-based differential positioning (DCDP) method is widely used to avoid the influence of errors. In this method, the positioning information of multiple base stations is uploaded to the data center, and the positioning errors are calculated uniformly by the data center based on the minimum variance or a weighted average algorithm. However, the DCDP method has high delay and overload risk. To solve these problems, this paper introduces edge computing to relieve pressure on the data center. Instead of transmitting the positioning information to the data center, a novel method called edge computing-based differential positioning (ECDP) chooses the nearest reference station to perform edge computing and transmits the difference value to the mobile receiver directly. Simulation results and experiments demonstrate that the performance of the ECDP outperforms that of the DCDP method. The delay of the ECDP method is about 500ms less than that of the DCDP method. Moreover, in the range of allowable burst error, the median of the positioning accuracy of the ECDP method is 0.7923m while that of the DCDP method is 0.8028m.
