Impact of tropospheric turbulence on non-Geostationary communication systems

The Geostationary Fourier Imaging Spectrometer (GeoFIS) as part of the Geostationary Tropospheric Pollution Explorer (GeoTroPE) mission: objectives and capabilities

The Geostationary Fourier Imaging Spectrometer (GeoFIS) is proposed as part of the European Geostationary Tropospheric Pollution Explorer (GeoTroPE) mission. For this mission, two instruments are considered: one covering the thermal infrared region (GeoFIS) and one covering the ultraviolet–visible and near-infrared regions (GeoSCIA). The geostationary orbit (GEO) provides indeed a unique opport...

Analytical method for determining the statistics of interference between non-geostationary-satellite orbit fixed-satellite service systems and other non-geostationary-satellite orbit fixed-satellite service systems or geostationary-satellite orbit fixed-satellite service networks

Monitoring tropospheric pollution using infrared spectroscopy from geostationary orbit

This paper presents the Geostationary Fourier Imaging Spectrometer (GeoFIS), a new satellite instrument that has been proposed to monitor tropospheric key pollutants (O3, CO) in order to improve the predictive capability of tropospheric chemistry models. The horizontal resolution of GeoFIS is about 15× 15 km2 and the temporal resolution is about 60 minutes. It is shown that the current instrume...

The Impact of Business Intelligence on Marketing Performance with Moderating Role of Environmental Turbulence

In today's complex, dynamic and constantly changing environment, companies need to design and take systems and methods that can help them adapt themselves to the changeable and dynamic situation of competitive markets, and therefore improving marketing performance and generally the company’s performance. In this regard, business intelligence systems as a new method and tool can be considered as...

Application of Single-Mode Fiber-Coupled Receivers in Optical Satellite to High-Altitude Platform Communications

In a free-space optical communication system employing fiber-optic components, the phasefront distortions induced by atmospheric turbulence limit the efficiency with which the laser beam is coupled into a single-mode fiber. We analyze different link scenarios including a geostationary (GEO) satellite, a high-altitude platform (HAP), and an optical ground station (OGS). Singlemode coupled optica...
