• The CB and NESC developed and documented normal point data submission procedures including backup modes.
• Site Logs were completed by the most of the ILRS network stations by the end of 2000.
• Ulrich Schreiber published the results from the first SLR Calibration Colloquium held in Florence, Italy (September 1999).

1999

• The first Networks and Engineering Standing Committee (NESC) meeting was held in September 1999, in Florence, Italy. During this meeting, the members of the SC were finalized. The following 6 major activities were defined based on the NESC Charter. In order to distribute the work load, each committee member was assigned one or more fields of activities.
• The CB developed the ILRS Bibliography, an online collection of papers, reports, descriptions, manuals, etc.
• The CB generated a list of catalogue of quality checks performed by the various analysis centers.
• HTSI developed an automated format and data integrity program for ILRS normal point (ref: data integrity and format algorithm)
• The NESC email exploder was created (ilrs-newg @ lists.nasa.gov).
• The Data Centers developed a satellites prediction flow chart.
• W. Gurtner developed an ILRS site log form based on the IGS site log form.
• EUROLAS developed a real-time system status exchange, including recently tracked satellites and their time biases. The ILRS CB established a weekly network status report.
• Stefan Reipl develop a program to compute satellite link budgets, normalized for LAGEOS (ref: http://www.wettzell.ifag.de/publ-cgi-bin/linkbudget.py).
• Ulrich Schreiber organized and conducted the first SLR Calibration Colloquium held in Florence, Italy (September 1999).
