Transformation of Observations, Part 3
Above: Typical and low-distortion map projections. Using a Project Factor In Part 1 of this series of articles (September 2014 issue), I explained how to transform surface observations into a geocentric coordinate system so that it could be compared to GNSS baseline vectors. In Part 2 (December 2014) I explained how the creation of a...

GNSS Next: A Control Center for Real-time GNSS Data
Editor’s Note: GNSS is a global amenity that all segments of society now rely on. While low-precision uses of GNSS can work with the default broadcast products alone, directly from the satellites, all high-precision GNSS uses rely to varying degrees on external “value added” data products. These products, such as enhanced clock and orbit data, are...
