| Zusammenfassung |
| The ESA BepiColombo mission, for the exploration of planet Mercury, has been
rescheduled for launch in 2014 with a redesigned two–satellite configuration. Among
the main scientific objectives of this mission are the gravimetry and rotation of
Mercury and tests of Einstein’s theory of general relativity, to which the ISA (Italian
Spring Accelerometer) instrument on–board the MPO (Mercury Planetary Orbiter)
spacecraft will give a fundamental contribution by providing a continuous measurement
of the non–gravitational accelerations acting on the spacecraft itself. Following
a recent redefinition of the Radio Science procedure, in which the equations of
motion are formulated with respect to the accelerometer reference point, the error
budget for the instrument has been updated. This will be discussed, together with the
calibration strategies which are being developed for the various mission phases. |
