Most GNSS survey failures aren’t equipment—they’re poor site selection.

I’m experimenting with using low-cost GNSS receivers (L76K vs u-blox MAX-M10S) to pre-qualify sites before running NOAA OPUS.

~30–90 min logs → PostgreSQL → HDOP, CN0, wander analysis.

Early results show tradeoffs between signal strength and positional stability.

Anyone exploring similar GNSS site validation?

Laser Ranging Makes GPS Satellites More Accurate

The oceanic tidal pulse extends significantly deeper into terrestrial waterways than previously recognized, serving as a highly dynamic force that continuously alters the physical and biological landscapes of coastal rivers.

Earth orientation parameters (Earth 🌍)

In geodesy and astrometry, earth orientation parameters describe irregularities in the rotation of planet Earth. EOP provide the rotational transform from the International Terrestrial Reference System to the International Celestial Reference System, or vice versa, as a function of time. Earth's rotational velocity is not constant over time.

Dear geodesists, astronomers, and astrophysicists: Does any of you know of some publication that explicitly reports the expression for the metric in a Geocentric Terrestrial Reference System (GTRS) or in the more specific International Terrestrial Reference System (ITRS)?

Various publications (eg https://doi.org/10.1086/378162) and textbooks (eg https://doi.org/10.1017/CBO9781139507486) report and discuss the metrics for the Geocentric Celestial Reference System (GCRS), but not for the GTRS. (Even though it seems to me that the expression should be formally identical, as the off-diagonal timelike components take care of rotation).

Cheers! (Sorry for spamming borderline hashtags.)
