Since 2007 VLBI Space Debris ranging is one of on-going activities in Ventspils International Radioastronomy Centre (VIRAC). The bulk of observations happened in collaboration with so called LFVN (Low Frequency VLBI Network).
Work on upgrade and repair of receiving hardware of RT-32 is of high priority in VIRAC. During the last year the receiving station at second focus of the telescope was reconstructed and a new 5 GHz single-band receiver was installed.
At the moment data registration systems are Mark II and the original terminal TH-16 (developed in Nizhniy Novgorod Radiophysical Research Institute). Correlator for VLBI data processing and program complex for calculation of orbit elements and prediction of their coordinates are under active development.
During this effort the conclusion is made that simultaneous optical observations of the same objects could sufficiently increase the precision of determination of the trajectory of the observed space debris.
Results of last test session with renewed equipment and gained lessons are discussed.
