FISICA (Far Infrared Space Interferometer Critical Assessment) is an FP7 program of the European community that aims to bring together the leading international experts on FIR (Far InfraRed) space instrumentation, in the effort to identify the scientific questions connected to high spatial resolution observations in the FIR and to translate these questions(More)
We propose a dedicated mission in low Earth orbit to test the gravitational interaction and place improved limits on the atmospheric density at the altitudes of interest. A very simple spacecraft would be placed in a dawn-dusk eccentric orbit between 500 and 1200 km. It should be tracked with high precision, and an on-board accelerometer would measure the(More)
A cryogenic differential accelerometer has been developed to test the weak equivalence principle to a few parts in 10(15) within the framework of the general relativity accuracy test in an Einstein elevator experiment. The prototype sensor was designed to identify, address, and solve the major issues associated with various aspects of the experiment. This(More)
The models developed so far to account for the Non-Gravitational Perturbations (NGP) acting on the satellites of the Global Navigation Satellite Systems (GNSS) constitute the present limit for further improvements in the Precise Orbit Determination (POD) of these satellites. These models are mainly based on the estimate of empirical parameters (with the(More)
The Italian Spring Accelerometer (ISA) is an high-sensitivity instrument designed to measure very small accelerations. As such, it is suitable for a number of applications, notably the measurement of non-gravitational accelerations acting on the surface of a spacecraft. ISA has been selected to fly on board the forthcoming BepiColombo mission for the(More)
We present here the concept for a new experimental test of the Weak Equivalence Principle (WEP) carried out in the gravity field of the Sun. In this experiment, two test masses of different materials are the central elements of a differential accelerometer with zero baseline. The differential accelerometer is placed on a pendulum, in such a way as to make(More)
In the last ten years many proposals and studies have been advanced for a far-IR kilometer baseline interferometer. This paper shows the results of FISICA (Far Infrared Space Interferometer Critical Assessment), an FP7 program of the European Community. In particular, we focus on an innovative strategy to cover the plane of observation with a minimal(More)
The European project “Wind, Ports, and Sea” (VPM), funded by the European Cross-border Programme “Italy-France Maritime 2007-2013”, aims to improve the safety conditions and to reduce the hazards by the development of a coupled monitoring and forecast system of the sea-state outside the main harbors of the Northern Tyrrhenian and(More)
