Macroinvertebrates are one of the key components of lake ecosystems and are required to be monitored alongside other biological groups to define ecological status according to European Union legislation. Macroinvertebrate communities are highly variable and complex and respond to a diverse series of environmental conditions. The purpose of this study was to(More)
Recommended by Abbas Mohammed Results from a measurement campaign emulating the high altitude platform (HAP)-to-indoor communication channel at S-band are presented in this paper. A link was established between a transmitter carried by a helicopter, representing the HAP, and a receiver placed at several locations in different building types including an(More)
— Reliable propagation models are required for the design of satellite broadcast to mobile or satellite navigation systems at S-band in the indoor environment. In particular, these models will support the development of hybrid satellite systems including complementary ground components. Apart from the effects of shadowing and multipath encountered in LMS(More)
SUMMARY This paper presents a hybrid empirical-statistical model for the satellite-to-indoor propagation channel at S-band derived from measurements using a helicopter to simulate the satellite. The measurements have been carried out by means of a wideband, circularly polarized channel sounder in a SIMO (Single Input Multiple Output) configuration, allowing(More)
The paper describes an automated data processing system of propagation measurements from satellite beacon in the microwave spectral range. The software has been developed in the framework of the ESA contract "Data Collection and Processing System for the Alphasat TDP5 Ka/Q Band Propagation Experiment" with the purpose to offer a common data processing(More)
