N2 - Many spatially distributed radio frequency (RF) measurement setups require coherence, i.e., synchronization of their local oscillators (LOs). In static setups, this can be achieved by distributing a common reference clock signal over a wired cable infrastructure. In mobile setups without wired infrastructure, synchronization can be achieved using global positioning system (GPS)-disciplined oscillators (GPSDOs). However, those typically incorporate rather bulky crystal oscillators, which are inherently sensitive to mechanical stress, i.e., vibration and temperature fluctuation. In contrast, micro-electromechanical system (MEMS) oscillators are less sensitive to environmental influences, while maintaining a small footprint. This paper presents a compact MEMS-based GPSDO concept with real-time kinematic (RTK) support for mobile applications. Measurements for short-and long-term frequency stability of the fabricated design are shown.
