DBBC3: AntArr Project
Full text linkLow frequency bands in a traditional VLBI networks suffer not only from RFI but also from the
low efficiency of the radio telescopes. Dedicated arrays have to be used which have to maintain
all the constraints of a VLBI station, e.g., phase stability. With this aim a project with an
alternative application of the DBBC3 was set up and is presented, where a set of antennas
operating at frequencies lower than 1 GHz are combined into an array. The individual antennas
cover the broadband frequency range from 10 MHz to 1000 MHz
PMD Analysis Center 2013 Annual Report
Full text linkThis report summarizes the activities of the
Politecnico diMilano (PMD) IVS Analysis Center during
the year 2013 and outlines the planned aspects
of work for 2014. The main focuses in 2013 were in
the framework of the IAG WG 1.4.2 on Co-location
on Earth and in Space for the determination of the
Celestial Reference Frame. Studies carried out concern
e.g. simulations for some European VLBI antennas
performed to investigate if the VLBI phase referencing
technique can be used for precise determination
of GNSS state vectors. Furthermore, investigations
into possible deformations introduced by the change to
ICRF2 [1] were also made for the processing of 24-
hour observational session
