At the same time, the antenna cable will be replaced. The cable type remains the same as before: Andrew FSJ1-50A phase stabilized with very low temperature sensitivity. The cable is being replaced with one whose electrical length has been very accurately measured. The data download and RINEX translation procedures for USNO conform to the recommendations of IGS Mail 2320 (24 June 1999) for handling mixed receiver types. An updated site log will be sent to the IGS Central Bureau after the changes are completed. ========================================================================= Jim Ray e-mail: jimr@maia.usno.navy.mil U.S. Naval Observatory, EO Dept. phone : 202-762-1444 3450 Massachusetts Avenue, NW fax : 202-762-1563 Washington, DC 20392-5420 ========================================================================= [Mailed From: Jim Ray (USNO 202-762-1444) ]
