There evidenly exist some Trimble data download software versions that swap the values into the wrong order. The public RINEX converters teqc (UNAVCO) and TRRINEXN (Bern University) have been modified to put the values into the correct order. All agencies creating RINEX from Trimble receivers using these converters should please upgrade to the most current version. teqc users may see http://www.unavco.ucar.edu/html_mail/teqc/msg00247.html or contact Lou Estey (lou@unavco.ucar.edu); TRRINEXN users may contact Werner Gurtner (werner.gurtner@aiub.unibe.ch) with any questions. With thanks to those who discovered the effect and those who provided the new converters, Angie ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Angelyn W.
