Experience and results of the 1991 MTLRS-1 USSR campaign

The year 1991 was a special year for the mobile laser ranging systems. Due to the scheduled upgrades of the Modular Transportable Laser Ranging Systems, MTLRS#1 and MTLRS#2, neither a WEGENER MEDLAS nor a Crustal Dynamics Project campaign was carried out in 1991. After the successful upgrade of MTLRS#1 in the first half of 1991 the system departed from Wettzell in August to make measurements at two sites in the USSR. In Riga/Latvia, we operated close to the fixed SLR system. In Simeiz/Ucrainea, the place for MTLRS#1 pad was choosen to collocate the two fixed SLR stations in Simeiz (300 m distance to MTLRS#1) and Kazivelli (about 3 km distance).
