The University Navstar Consortium facility announces that an investigator's manual and a number of technical reports are available. The Investigator's Manual is intended primarily for UNAVCO members interested in using the UNAVCO facilities for GPS field projects, but it may also be of interest to others planning GPS fieldwork. For users with Internet access, the manual is available via anonymous ftp as a postscript file. A hard copy may be requested from Barbara Perin at UNAVCO (address below).
