The Navigation Systems Laboratory in Moscow has a team of 11 people who specialize in global navigation satellite systems. They have been operating since 2004 and have a large budget for research and development projects. Some of their projects include designing new CDMA signals for GLONASS, developing an FPGA-based GNSS receiver/transmitter called CoreZh, creating precise GNSS receivers for laser control stations, and implementing spatial-time adaptive processing using multiple antennas. They have also developed integrated GNSS/INS systems and designed GNSS simulators and spoofers. Their newest hardware platform is called Clonicus, which uses a Zynq chip and can be expanded with additional boards like one containing a wideband transce
