WATCH MARKET OEM 2 Photo Septentrio nals to complex wideband and pulsed jammers the company said In addition the integrated spectrum analyzer allows the RF environment around any Mosaic module to be viewed in real time in both time and frequency domains Effective interference countermeasures against threats to GNSS signals also require constant knowledge of the changing RF environment The Mosaic module helps analyze these threats by continuously and automatically monitoring the GNSS frequency spectrum to detect characterize log and mitigate interference events when needed vector commands and testing user equipment for leapsecond and GPS week rollover event compatibility to identify weaknesses in user equipment The unit does not require a PC to be connected to it to function This makes embedded operation as easy as applying power and connecting the units RF output to the antenna input of any GPS receiver Legacy Upgrades By generating a legacy RF GPS signal from any secure PNT source the Micro Transcoder allows users to maintain their investment in fielded legacy GPS equipment Example applications include retrofitting financial transaction time servers with CSAC or rubidium atomic clock holdover capability and adding GPS RF output capability to concurrent GNSS receivers to allow reception of L1 L2 L3 L5 GPS GLONASS Galileo BeiDou QZSS Iridium STL or any other satellite based navigation signal to legacy GPS receivers It can also be used to add inertial navigation system INS capability to vehicles and aircraft TRANSCODER continued from previous page MOSAIC continued from previous page JANUARY 2019 WWW GPSWORLD COM GPS WORLD 37
