Enhanced Web Interface for Lunar Laser Ranging Observations

This project presents a user-friendly web interface designed for the preparation and validation of Lunar Laser Ranging (LLR) observations. Distant LLR observers can compute predictions for geocentric and topocentric coordinates of lunar targets, and estimate round-trip times of laser pulses between Earth stations and lunar retro-reflectors. The platform allows users to compare their observations with computed lunar solutions and reduction models through real-time access. Built in PHP with core processing in Fortran, it simplifies the user experience compared to traditional Fortran programs.

  1. Web Interface for Lunar Laser Ranging Observations Authors In alpha. Order : ChristopheBarache, SebastienBouquillon, T.Carlucci, F. Deleflie, D. Feraudy, G. Francou, H. Manche, E. Samin, J-M. Torre

  2. Objectives - Construct a web interface for the preparation and the validation of Lunar Laser Ranging (LLR) observations. =>Distant LLR Observers will be able to compute : - predictions of geocentric and topocentric coordinates of lunar targets - predictions of round-trip times of laser-pulses between terrestrial stations and lunar retro-reflectors =>Distant LLR Observers will be able to compare their own LLR observations with computation of lunar solutions and reduction models with a real-time access

  3. Web Interface Available at http://polac.obspm.fr/PaV/

  4. Web Interface - Predictions Results Area : (previewpredictionrequested and CPF format) Submission Area: (Lunar solutions and reductionmodels)

  5. Web Interface – Validations (1) Submission Area : (Available formats data and user’s data capture area) Results Area : (Validation process for each LLR observation and statisticresults)

  6. Web Interface - Validations (2) Results Area : (Graphs of residuals)

  7. Conclusion - Web Interface is more “friendly” and easier to use than with the orignalfortran programs - Web Interface is built in PHP and the main processing is kept in Fortran language (better than rewriting all the programs) TO DO LIST : - Add a Votable data file possibility to provide our data to other OV Tools (like TopCat) or other scientific tools - Wait for the users viewpoint to improve this Web Interface
