NRTK, PPP or Static, That Is the Question. Testing Different Positioning Solutions for GNSS Survey
نویسندگان
چکیده
Worldwide, the determination of 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 those have carried out to compare Positioning (PPP), Kinematic (NRTK), modes’ solutions, usually, using latter as true most plausible solution. This approach is not always possible mode solution depends on parameters (baseline length, acquisition time, ionospheric, tropospheric models, etc.) that must be considered evaluate accuracy method. work aims show comparison among GNSS methods mentioned above, some benchmark points. The tests were by comparing pairs check their solutions congruence. NRTK refer local CORS network’s analysis. positioning obtained with different (VRS, FKP, NEA) PPP calculated two software (RTKLIB CSRS-PPP). A statistical performed if distribution frequencies coordinate’s residual belong normal distribution, for all analysed. results hypothesis confirmed and, specifically, Static vs. pair seems achieve best congruence, while involving approach, CSRS better congruence than RTKLIB software.

GNSS Network Real-Time-Kinematic (NRTK) has become a common service for many precise positioning applications over the last two decades. However, NRTK cannot service or support user applications if they are outside the Continuously Operating Reference Stations (CORS) network coverage area, such as in the case of offshore surveying. In addition, NRTK requires a fairly dense network of CORS (typi...

The modes of reproduction undoubtedly represent one of the most critical life-history traits because they profoundly affect fitness and survival. The parent-offspring conflict over the degree of parental investment may be the main selective factor in the evolution of reproduction. Although the modes of sexual reproduction are remarkably diversified in animals, the traditional typology spanning ...

Primary cardiac tumors are rare in all age groups, with a reported prevalence of 0.001--0.03% in autopsy series. We report the case of a 37-year-old man, with no relevant medical history, who was admitted to the emergency department with sudden-onset right hemiparesis. Diagnostic studies revealed a small hypodense area in the left putamen and he was admitted to the stroke unit with a diagnosis ...

Bioenergy currently draws worldwide attention, both positive and negative. Proponents argue that the large-scale development of bioenergy, more precisely of biofuels, could be part of the solution for diversifying energy sources, enhancing security of energy supply, and meeting environmental and rural development objectives. Opponents argue that it could drive up prices of agricultural products...
