As president-elect of the American Association for Geodetic Surveying (AAGS), I participated in a joint quarterly meeting with the National Geodetic Survey (NGS), the National Society of Professional ...

The signals will be observed by all geodetic VLBI antennas, including the new VLBI Global Observing System (VGOS) fast slewing stations, in their standard geodetic receiver setups. The transmitter ...

Geodetic leveling, as the process was called, was painstaking and expensive. ... But there was a big catch. “GPS doesn’t know much about gravity,” said James L. Davis, ...

Geodnet CEO Mike Horton tells TheStreet how a token-incentivized GPS network is delivering centimeter-level accuracy across farms, highways, and beyond.

The World Geodetic System 1984 (WGS 84) is a three-dimensional coordinate reference frame for establishing latitude, longitude and heights for navigation and positioning.

Observations were made using Trimble 4000 SSE and 4000 SSI, dual-frequency, dual P-Code GPS receivers and L1/L2 geodetic ground plane antennas. SECO fixed-height antennas, ...
