Ground deformation in the Central
Andean plateau was monitored by processing Sentinel-1 (S-1) images
from 2014 to 2018, using Interferometric Synthetic Aperture
Radar(InSAR)with the millimeters accuracy. S-1 images are processed
and interferograms are generated and unwrapped to perform time series
analysis of deformation using Small Baseline Subsets (SBAS) as a
multi-temporal InSAR methodology. Additionally, the effects of water
vapor and atmospheric waves on the interferograms are investigated.

The study focuses on providing a climatology of
equatorial scintillation phenomenon, so called plasma bubbles,
occurring at low latitude region of the ionosphere. For this thesis
work, a decade long GPS radio occultation measurements obtained from
the constellation of FormoSat-3/COSMIC (2007-2016) is taken into
account. The six FormoSat-3/COSMIC satellites provide in total about
2,000 radio occultation profiles per day on an average. About 5
million profiles were processed for this study, of which 0.2%
contained strong disturbances in the ionospheric F-region.

A U-Blox M8T Global Navigation Satellite System (GNSS)
receiver and a Raspberry Pi 3 board computer were used in order to
construct a low-cost GNSS data recorder. The goal of this procedure is
to show that the construction of this device is straightforward and it
does not require extended knowledge about electronics and programming.
All materials used for the construction are simple and cheap. The
control of the data recorder can be done by any smartphone.

Soil moisture is a key parameter in hydrological cycle. It is also an
important component from a socio-economical perspective. Knowledge
about soil moisture is beneficial for many applications such as
agricultural, health, and water management programs as well as water
related disasters management. Several techniques are in use, including
in-situ and remote sensing to measure this parameter, soil moisture.
However, the desiredaccuracy in the appropriate spatial and temporal
resolutions remains a major challenge.

The adapted GNSS receiver, GORS, set up near the village
of Ny-Ålesund in the island of Spitsbergen, Svalbard, was used to
monitor GNSS reflections on the adjacent Kongsfjorden. Two antennas,
one up-looking Right-Hand Circular Polarized (RHCP) and one
horizon-tilted Left-Hand Circular Polarized (LHCP), installed at the
Zeppelin mountain, have been recording almost continuously since 2013.
The field of view from this location allows to capture reflections as
far as 14 km from the receiver's position, over the complete fjord and
nearby surrounding land areas, using an elevation view mask from 2°
to 10° above the horizon.

GEROS-ISS stands for GNSS REflectometry, Radio
Occultation and Scatterometry onboard the International Space Station.
It is a scientific experiment, proposed to the European Space Agency
(ESA) in 2011 to be installed aboard the International Space Station
ISS. GEROS-ISS is currently in phase A of realisation, the launch is
foreseen for 2019.
