Development Status of BepiColombo ISA Accelerometer |
|
Abstract |
To be launched in 2017, ESA mission BepiColombo will perform a thorough study of the planet Mercury and its environment. Among the wide range of its scientific objectives, an important set is constituted by the so-called Radio Science Experiments (RSE), which will study the gravitational field and rotation of the planet, and will perform very precise tests of general relativity theory. In order to reach the required level of accuracy in recovering the relevant parameters, the data coming from the high-sensitivity ISA (Italian Spring Accelerometer) instrument onboard the Mercury Planetary Orbiter (MPO) will be used - the first time for a deep-space probe - in the orbit determination and parameter estimation procedure. Following a brief description of the RSE in the context of the mission, the instrument and its wide capabilities will be reviewed. In particular the ongoing on-ground calibration activities (concerning both the calibration of actuators and that of sensing axes directions) will be described. |
