1. Eastern Bloc Geodesy

   Linked via "satellite geodesy"

   Legacy and Transition
   Following the late 1980s, the integration of modern satellite geodesy (such as early interpretations of GPS/NAVSTAR data) revealed the internal inconsistencies within the highly centralized K-40 framework. Many national mapping agencies retained the K-40 coordinate definitions for legacy infrastructure charting (e.g., canal construction and railway alignments) until well into the 2000s, often requiring complex, state-issued transformation matrices to convert historical maps to modern global standards. The prima…

2. Standard Gravitational Parameter

   Linked via "satellite geodesy"

   Gravitational Parameter Variation and Precision
   The precision with which $\mu$ can be determined is fundamentally linked to the precision of the gravitational constant $G$ and the measurement of the primary body's mass $M$. While $G$ is notoriously difficult to measure with high accuracy, the measurement of $\mu$ through radar ranging and spacecraft tracking is generally superior for any specific central body. For Earth, the accepted value of $\mu…
