After 121 days of successful operation, the Trimble SSE stopped tracking on May 16 (day 136) due to damage to the antenna as a result of rain water leakage. 2. The repair of the antenna was used as an opportunity to upgrade the receiver with an external frequency input option. When the receiver was returned, the new option did not function, necessitating new repairs and causing more delays. 3. After repair, in June, the antenna was mounted at a new position, (DOMES nr. 12309M002) a few meters away from the old point (DOMES nr 12309M001). Both points are on the roof of the 6 story office building of IMVP, but the old point was judged not stable enough. The new point is at the edge of the roof, anchored to the east wall of the building. The relative positions of the 2 points have been surveyed with GPS. The results will be distributed as soon as they have been verified. 4. Tracking and data distribution to IGS resumed on July 5 (day 186). Since that time the receiver has been connected to an H-maser!!! Due to various reasons the distribution of this message has been delayed considerably, which is regretable. However, it is felt that MDVO is an excellent station, especially after the repair of the antenna and in particular since the addition of the H-maser external frequency standard. Therefore, all Analysis Centers are encouraged to include this station in their analyses as well as its new sister station in Irkutsk (IGS message nr. 1085). Both stations represent a significant expansion of the IGS global network, and together with the stations in Kitab and Zvenigorod, they also signal the start of a densification of IGS in the CIS, which is expected to continue in the future. An updated site description form will be sent to the IGS Central Bureau soon. Boudewijn Ambrosius [Mailed From: Boudewijn Ambrosius ]
