“…The latter information will be used to determine the correct time-shifts in post-processing. It is gained by a combination of 1. spacecraft position triangulation by the Deep Space Network, 2. ranging with delayed pseudo random noise codes modulated onto the laser beams [47,48], and 3. raw data pre-processing by Kalman filters to recover the ranging information and base all measurements on a common reference frequency [49].…”

The most promising concept for low frequency (millihertz to hertz) gravitational wave observatories are laser interferometric detectors in space. It is usually assumed that the noise floor for such a detector is dominated by optical shot noise in the signal readout. For this to be true, a careful balance of mission parameters is crucial to keep all other parasitic disturbances below shot noise. We developed a web application that uses over 30 input parameters and considers many important technical noise sources and noise suppression techniques to derive a realistic position noise budget. It optimizes free parameters automatically and generates a detailed report on all individual noise contributions. Thus one can easily explore the entire parameter space and design a realistic gravitational wave observatory. In this document we describe the different parameters, present all underlying calculations, and compare the final observatory's sensitivity with astrophysical sources of gravitational waves. We use as an example parameters currently assumed to be likely applied to a space mission proposed to be launched in 2034 by the European Space Agency.

“…The measurement of the inter-spacecraft distance is performed thanks to a low frequency modulation of the laser frequency, transmitting and correlating pseudorandom codes. Another modulation (at about 1 GHz) is also required to transfer the Progress towards an electro-optical simulator for space based, long arms interferometers 5 noise of the on-board clocks and compensate for their effect on the analog to digital converters (ADC) timestamping [7,8,10,13,17,24,26,27]. These beat notes (carrying the 'science' as well as the ranging and clock synchronization signal) need to be measured at the level of the µcycle/ √ Hz, while following the frequency drifts between 5 and 25 MHz, due to the relative motion of the S/C.…”

We report on the progress in the realization of an electronic / optical simulator for space based, long arm interferometry and its application to the eLISA mission. The goal of this work is to generate realistic optics and electronics signals, especially simulating realistic propagation delays. The first measurements to characterize the simulator are also presented. With the present configuration, noise reduction factors of 5×107 for optical beat notes and 109 for RF beat notes have been achieved using the Time Delay Interferometry algorithm. The principle of the experiment has been validated and further work is ongoing to identify the residual noise sources and optimize the apparatus.

“…Until now, it has been assumed that we know the required interferometer arm-lengths and rate of change in order to form the TDI combinations but in practice this is not the case. Two primary methods, pseudo-random noise (PRN) ranging [25,26] and TDI-ranging [14], have been proposed to measure these time-dependent arm-lengths. Extending the root mean squared (RMS) power minimization TDI-ranging methods outlined by Tinto in [14], this experiment will, instead, modulate the laser phase signals with ranging reference tones at frequencies outside of the LISA measurement band.…”

This hardware-based experimental simulation of the Laser Interferometer Space Antenna (LISA) implements a real-time electronic duplication of the time-changing inter-spacecraft (SC) laser phase delays while measuring heterodyned laser fields with µcycle phasemeters. The beatnote measurements are used to verify the capabilities of theorized post-processing time-delay interferometry (TDI) combinations in the proper time-scaled and time-shifted linear combinations. The experiments meet the 18 pm/ √ Hz LISA measurement sensitivity goal after demonstrating the cancellation of 100 Hz/ √ Hz laser phase noise by TDI-ranging the time-varying arm-length to an accuracy better than 2.0 m using a frequency modulated ranging tone.
