The autonomous navigation technology of INS has always attracted the attention many scholars. In satellite-denied environment, making full use auxiliary sensors with characteristics can suppress dynamic error generated by in effectively. However, like an odometer (OD) and laser doppler velocimeter (LDV) will cause instability to system. To solve above problems, we propose improved inerital-base...

Flow mapping around bridge piers is crucial in estimating scour development potential under different flow conditions. The reliable measurement of turbulence and the estimation Reynolds stress can be achieved on scaled models controlled laboratory experiments using high-frequency Acoustic Doppler Velocimeter Profilers (ADVP) for measurement. aim this paper was to obtain operation parameters an ...

We present the discovery of an $18.5\pm0.5$M$_{\rm Jup}$ brown dwarf (BD) companion to M0V star TOI-1278. The system was first identified through a percent-deep transit in TESS photometry; further analysis showed it be grazing Jupiter-sized object. Radial velocity (RV) follow-up with SPIRou near-infrared high-resolution velocimeter and spectropolarimeter framework 300-night Legacy Survey (SLS) ...
