In the past few years is increasing the necessity of realizing high accuracy positioning. In this sense, the spatial technologies have being widely used. The GNSS (Global Navigation Satellite System) has revolutionized the geodetic positioning activities. Among the existent methods one can emphasize the network-based positioning. Applying this method is possible to obtain centimetric accu…
Radio occultation (RO) has been used with stars and space probes for the investigation of other planets' atmospheres over the last six decades. The development of GNSS (Global Navigation Satellite Systems) and LEO (Low Earth Orbit) satellites enabled the used of RO for exploration and investigation of the Earth's atmosphere. RO considers that the signals transmitted by GNSS satellites car…
Occultation is the phenomenon in which a celestial body ceases to be visible due to the superposition of another. The radio occultation (RO) technique has been widely applied with the use of stars and probes in order to investigate the atmosphere of other planets. The development of GNSS (Global Navigation Satellite System) and LEO (Low Earth Orbiting) satellites missions enabled the use …
GNSS (Global Navigation Satellite Systems) Radio Occultation (RO) enables investigations of the Earth's atmosphere. The signals propagated from GNSS satellites to the receivers onboard LEO (Low Earth Orbiting) satellites are influenced by the atmosphere in different ways. From the collected signal it is possible to calculate the refractive index and, with that, retrieve profiles of temper…
Global Navigation Satellite Systems (GNSS) have been increasingly employed in activities that require position estimates. In addition to the North American GPS (Global Positioning System), GLONASS, developed by the former Soviet Union and which is in full constellation, the European Galileo and the Chinese BDS also orbit the Earth, both being implemented, achieving full constellation by 2…
Integer ambiguity resolution is the process of determining the unknown number of double differences (DDs) integer cycles of the carrier phase and is essential for obtaining high accuracy in GNSS applications. As the process of ambiguity resolution is not trivial, it is necessary to use success indicators. For this purpose the Ambiguity Dilution Of Precision (ADOP) measurement was introduc…

Global Navigation Satellite System (GNSS) radio occultation (RO) enables investigations of the Earth's atmosphere. From GNSS satellites to the receivers onboard Low Earth Orbiting (LEO) satellites, the propagated signals are influenced by the atmosphere in different ways. This makes it possible to calculate the refractivity, which provides information on the composition of the atmosphere,…
The radio occultation (RO) technique allows the retrieval of atmospheric profiles, which can contribute to investigations of the Earth's atmosphere, including the detection of climate variations, monitoring of extreme events and numerical weather prediction. Initially RO was used for the exploration of the atmosphere of other planets. The development of GNSS (Global Navigation Satellite S…
With the passing of the years the need to perform positioning with high accuracy has grown. In this sense, space technologies have been widely used. Global Navigation Satellite Systems (GNSS) have revolutionized activities involving geodetic positioning. In order to achieve the desired accuracy, it is essential to model the atmosphere (ionosphere and troposphere) in an appropriate way. Co…
Global Navigation Satellite System (GNSS) based positioning was initiated in the 1970's, when GPS (Global Positioning System) was launched. In the late 1990's/early 2000's the European Union started the development of its own system, Galileo, which already has 15 operational satellites in orbit. The integration of these systems for positioning activities is advantageous due to the large n…
