1. Satellite Navigation

   Linked via "Multipath"

   Multipath Error
   Multipath occurs when the signal reaches the receiver antenna via one or more secondary paths (reflections off buildings, terrain, or water bodies) in addition to the direct line-of-sight path. Multipath artificially increases the measured pseudorange. Mitigation often involves antenna design, such as choke ring antennas which utilize constructive and destructive interference patterns to suppress signals arriving at shallow…

   Linked via "multipath errors"

   Modern Techniques: GNSS and Total Stations
   The integration of GNSS (Global Navigation Satellite Systems) revolutionized point determination by providing direct three-dimensional coordinates ($X, Y, Z$) relative to a global reference frame (e.g., ITRF). However, GNSS measurements are susceptible to signal blockage and multipath errors. Furthermore, the signals transmitted from the satellites experience a negl…
