21 Aug 2020 | Abstract: | The TianQin-1 satellite (TQ-1), which is the first technology demonstration
satellite for the TianQin project, was launched on 20 December 2019. The first
round of experiment had been carried out from 21 December 2019 until 1 April
2020. The residual acceleration of the satellite is found to be about
$1 imes10^{-10}~{
m m}/{
m s}^{2}/{
m Hz}^{1/2}$ at $0.1~{
m Hz},$ and
about $5 imes10^{-11}~{
m m}/{
m s}^{2}/{
m Hz}^{1/2}$ at $0.05~{
m
Hz},$, measured by an inertial sensor with a sensitivity of
$5 imes10^{-12}~{
m m}/{
m s}^{2}/{
m Hz}^{1/2}$ at $0.1~{
m Hz},$. The
micro-Newton thrusters has demonstrated a thrust resolution of $0.1~mu{
m N}$
and a thrust noise of $0.3~mu{
m N}/{
m Hz}^{1/2}$ at $0.1~{
m Hz}$. The
residual noise of the satellite with drag-free control is $3 imes10^{-9}~{
m
m}/{
m s}^{2}/{
m Hz}^{1/2}$ at $0.1~{
m Hz},$. The noise level of the
optical readout system is about $30~{
m pm}/{
m Hz}^{1/2}$ at $0.1~{
m
Hz},$. The temperature stability at temperature monitoring position is
controlled to be about $pm3~{
m mK}$ per orbit, and the mismatch between the
center-of-mass of the satellite and that of the test mass is measured with a
precision of better than $0.1~{
m mm}$. | Source: | arXiv, 2008.09534 | Services: | Forum | Review | PDF | Favorites |
