The Laser Interferometer Space Antenna (LISA) is a European Space Agency mission that aims to measure gravitational waves in the millihertz range. The three-spacecraft constellation form a nearly-equilateral triangle, which experiences flexing along its orbit around the Sun. These time-varying and unequal armlengths require to process measurements with Time-Delay Interferometry (TDI) to synthesize a virtual equal-arm interferometer, and reduce the otherwise-overwhelming laser frequency noise…

Experimental verification of intersatellite clock synchronization at LISA performance levels
The Laser Interferometer Space Antenna (LISA) aims to observe gravitational waves in the mHz regime over its 10-year mission time. LISA will operate laser interferometers between three spacecrafts.

Algorithm for time-delay interferometry numerical simulation and sensitivity investigation
In this work, we introduce a generic algorithm to numerically determine the time delays and spacecraft positions for a time-delay interferometry (TDI) channel in the dynamical case, and streamline
