Preliminary analysis for the joint autonomous orbit determination of the BDS-3 MEO satellites and lunar ELFO satellites based on inter-satellite links

Abstract A fundamental limitation of Autonomous Orbit Determination (AOD) for Global Navigation Satellite Systems (GNSS) constellations using Inter-Satellite Links (ISLs) is the inherent unobservability of the overall rotational bias, leading to continuous degradation of orbit de...

A TSV-packaged SP6T RF MEMS switch with ultra-thin profile and suppressed substrate loss for DC to Ku band application

The evolution of wireless communication imposes stringent requirements on RF front-end modules, specifically demanding switches with ultra-thin profiles and wideband coverage up to Ku band. However, conventional packaged MEMS switches often result in excessive device height, crea...
