BLOCK-HF: CRT gains new ground

The detrimental effects of chronic right ventricular (RV) pacing were first demonstrated 10 years ago when the DAVID trial clearly demonstrated the hazards of unnecessary RV pacing including worsening left ventricular (LV) function, increased heart failure hospitalization and increased mortality. This finding was confirmed in other studies, prompting the development of various device algorithms...

Galileo Sensor Station Ground Reference Receiver Performance Characteristics

The Galileo Ground Segment design includes a global network of Galileo Sensor Stations (GSS) to be used for orbit determination, time synchronization, and integrity determination. NovAtel, under contract to ESA, is developing the requirements for the high quality Ground Reference Receivers to be used in the GSS. During the design process NovAtel is leveraging their experience as the world’s lea...

Final Report for Florida Middle Ground Project

We planed to conduct a “mowing the lawn” type of multibeam bathymetry and backscatter survey of the Florida Middle Ground HAPC (Habitat Area of Particular Concern; Figure 1) and to collect some ground truth data. The survey was to augment the existing coverage in the area from a previous USF cruise and will entail for the most part very long lines compared to the number of turns (Figure 1). The...

Io after Galileo

Io, the volcanically active innermost large moon of Jupiter, was a target of intense study during the recently completed NASA Galileo mission to Jupiter (1989–2003). Galileo’s suite of instruments obtained unprecedented observations of Io, including high spatial resolution imaging in the visible and infrared. This paper reviews the insights gained about Io’s surface, atmosphere and space enviro...

Economic Galileo E5 Receiver

The Galileo system introduces an extremely wideband civil E5 signal for high precision navigation. The structure of the receiver for the E5 signal is complicated due to the signal complexity and the large bandwidth. It is possible to process the whole E5 signal or process separately E5a and E5b parts combining obtained results afterwards (we call here such method as piece-wise processing). The ...
