"Earthbound labs occupy a periodically jerked frame — one with a rich derivative structure that free-fall frames lack entirely." The 4th Dialog #1: Cell Life & Wobbly Earthbound Reference Frames thecopernicanproject.org/4th-dialog/ #Physics #ReferenceFrames #Biophysics #TheCopernicanProject

Since #ReferenceFrames are germane to any measurement problem, have to nail down: 1) Special relativity - inertial reference frames 2) General relativity - any reference frame, including accelerating

📢 The Community of Interest on Geodetic Reference Frames – Europe is organizing the webinar “Quo Vadis Geodesy?” on Tuesday August 20th 2024 #Geodesy #ReferenceFrames un-ggim-europe.org/events/un-ggim…

Annual Report 2023 of @DgfiTum is now available. It highlights our last year's research activities on #SpaceGeodesy, #ReferenceFrames, Satellite #Altimetry and Atmosphere/#SpaceWeather: mediatum.ub.tum.de/doc/1751072/17…

#Geodesy: The Importance of Geodetic Reference Frames bit.ly/490ri16 by @IAG_GGOS #ITRF #referenceframes #geospatial #positioning

New film by @IAG_GGOS on "Terrestrial Reference Frames - Connecting the World through Geodesy" with contributions by @DgfiTum highlights the fundamental importance of highly precise #ReferenceFrames for a wide range of scientific and societal applications: bit.ly/trf-film

New article in J. #Geodesy discusses the effect of reducing non-tidal loading in the computation of secular terrestrial #ReferenceFrames from Very Long Baseline Interferometry (#VLBI) along with the impact on jointly estimated Earth Orientation Parameters: doi.org/10.1007/s00190…

The latest Annual Report of @DgfiTum has been published. Read the review of our research activities in 2022 on #SpaceGeodesy, #ReferenceFrames, Satellite #Altimetry and Atmosphere/#SpaceWeather here: mediatum.ub.tum.de/doc/1716115/17…

@TU_Muenchen's #DiesAcademicus gives the floor to fellows in the TUM program for #Ukraine scientists: youtu.be/-k0zgXmKKn8?t=…. "The collaborative research has opened up new opportunities and horizons to us" says Dr Yuliia Semenova, working with us at @DgfiTum on #ReferenceFrames.

@MikeHeights3 @0liviajulianna Facts: This country has been far right for centuries. #referenceframes How else can I help you?

Alexander Kehm from @DgfiTum completed his doctorate with a dissertation on Strategies for the Realisation of Geocentric Regional Epoch #ReferenceFrames at the example of #SIRGAS. Congratulations! @SirgasAmericas

Direct Geocentric Realization of Regional Epoch #ReferenceFrames: Combining global #GNSS, SLR & #VLBI networks densified by a regional GNSS network delivers displacement series that are geocentric at any epoch and directly relate to geophysical processes: doi.org/10.1029/2021JB…

*RoboDK Tips & Tricks*: The reference frame of an object can be aligned with respect to its own geometry. This allows moving the reference frame of an object to a location that can be identified in a real setup. Learn more ow.ly/45fu50IwZUp #robodk #referenceframes
