The ESA's Mars Express solar corona experiments were performed at two solar conjunctions in the years 2015 and 2017 by a number of radio telescopes in the European VLBI Network. This paper presents the methods to measure the frequency and phase fluct

Very long baseline interferometry (VLBI) is a radio astronomy tool with very high spatial resolution. It uses two or more radio telescopes to track the faraway object and gets its visibility. The intensity distribution image of radio source can be ob

The Mars Express (MEX) passed through superior solar conjunction in June, 2015. The X-band telemetry signal of MEX with solar offset R in the range of 11 R⊙~160 R⊙ were recorded by Sheshan VLBI station. Phase scintillation and its power spectral
We introduce the cross spectrum based FRB (Fast Radio Burst) search method for VLBI observation. This method optimizes the fringe fitting scheme in geodetic VLBI data post processing, which fully utilizes the cross spectrum fringe phase information a

Real-time high-accuracy VLBI techniques played an important role in the Chinese lunar exploration mission in executing the soft landing of the ChangE-3 probe on the lunar surface. To make this possible, in-beam phase referencing was used to obtain ac

By observing deep space probes and adjacent extragalactic radio sources alternatively, VLBI array acquire data which can be used for phase referencing radio imaging of deep space probes. The offset of the target source to the image center corresponds
