If applying as a Special Analysis Center, describe the special type(s) of
analysis you will perform. If applying as a Global Analysis Center, describe

the global analysis you will perform. Indicate your specific analysis
interests and describe how you select the data you analyze.


  1. Atmospheric radio wave propagation delay, modelling the effect of water
     vapor and possibly other neutral gases, measurement of water vapor
     content with radiometer and GPS, augmenting procedures in e.g.
     CALC/SOLV.
  2. Earth and ocean loading tides; new formulations of loading model  and
     implementation into software. Parameter estimation, special attention
     on covariance with other parameters like ocean tide terms in UT1/PM.
  3. Atmospheric pressure loading. Modelling using global fields. Dynamic
     response of near-by oceanic basins. Parameter estimation, special
     attention on covariance with other parameters like station positions.
  4. Antenna deformation and other local effects.

Describe the computer hardware configuration and the software package(s) you
use for analysis.

HP 700 series, UNIX 10.2, network of three file servers and a number of
workstations. CD-jukebox archive, cassette tape stations.
CALC/SOLV (GSFC), Globk (MIT), procedures m.i.t.h.

Internet connection type or bit rate: 1 Mbit/s    Data storage capacity: 50Gb

Describe any planned facility upgrades.

Number of full-time-equivalent personnel assigned to analysis center
functions: 2

Indicate which data center(s) you use: GSFC; University Bonn; BKG Leipzig

Indicate which of the following IVS Analysis Center functions you will
perform and explain briefly how you will perform them:

     Provide timely feedback to stations
     Create high quality products and perform timely archiving and
distribution
     Place final results (TRF, CRF, EOP, and others) in IVS Data Centers
*>>> Perform software development and documentation <<<***
*>>> Compare products <<<***
*>>> Adhere to IERS Conventions <<<***  (and develop)

Attach a list of personnel (names and titles) whom you designate as IVS
Associate Members through their affiliation with your analysis center.

Ruediger Haas, Dr.
Jan M. Johansson, Dr.
Hans-Georg Scherneck, Dr.

Please provide any other information that you feel will be helpful in
demonstrating your analysis center's capabilities to participate in the IVS.

If you proposed to the IERS in 1995/6 as an analysis center and wish to have
that proposal carry over to the IVS, please make such a statement in this
proposal.

Your signature on this form indicates your agreement to participate in the IVS
as an Analysis Center and to work closely with the IVS Analysis Coordinator.

If this is a new proposal (i.e. not carried over from IERS) your signature
commits your organization to participate in the IVS.

Name of person signing: Roy S. Booth   Title: Prof. and head of department
