Fifteen years of millimeter accuracy lunar laser ranging with APOLLO: data reduction and calibration
Nicholas R. Colmenares, James B. R. Battat, Daniel P. Gonzales +2
The Apache Point Lunar Laser-ranging Operation (APOLLO) has been collecting lunar range measurements for 15 years at millimeter accuracy. The median nightly range uncertainty since…
Fifteen years of millimeter accuracy lunar laser ranging with APOLLO: dataset characterization
James B. R. Battat, Eric Adelberger, Nicholas R. Colmenares +7
We present data from the Apache Point Observatory Lunar Laser-ranging Operation (APOLLO) covering the 15-year span from April 2006 through the end of 2020. APOLLO measures the eart…
The Planetary Ephemeris Program: Capability, Comparison, and Open Source Availability
John F. Chandler, James B. R. Battat, Thomas W. Murphy +3
We describe for the first time in the scientific literature the Planetary Ephemeris Program (PEP), an open-source general-purpose astrometric data analysis program. We discuss, in…
Timing calibration of the APOLLO experiment
J. B. R. Battat, L. R. Huang, E. Schlerman +3
The Apache Point Observatory Lunar Laser-ranging Operation (APOLLO) began millimeter-precision ranging to the Moon in 2006. Until now, a comprehensive validation of APOLLO system r…
A Radio System for Avoiding Illuminating Aircraft with a Laser Beam
W. A. Coles, T. W. Murphy, J. F. Melser +5
When scientific experiments require transmission of powerful laser or radio beams through the atmosphere the Federal Aviation Administration (FAA) requires that precautions be take…
Opportunities for Probing Fundamental Gravity with Solar System Experiments
Slava G. Turyshev, Thomas W. Murphy, Eric G. Adelberger +13
The recent discovery of "dark energy" has challenged Einstein's general theory of relativity as a complete model for our macroscopic universe. From a theoretical view, the challeng…
