Propagating PZ 90 to WGS 84 Transformation Parameters

The 29th Research Institute recently published its latest transformation parameters for WGS and PZ 90. Because these tranformation parameter estimates were derived from stations located within Russia, variance-covariance propagation was carried out to study the benefits of a better global distribution of stations. An example that includes two stations in North America is presented. The transformation improves significantly. © 1999 John Wiley & Sons, Inc.
