Popis:	The Main objective of the research proposal is to investigate Conducted Emission from power supply cable of Global Positioning System (GPS) based Vehicle Tracking System (VTS) and to make the system compatible with MIL-461E EMI/EMC standard. The Conducted Emission from GPS VTS Transmitter Board (SMS Based), GPS VTS Receiver Board (SMS Based) and GPS VTS Board (GPRS Based) had been measured with HAMEG make Line Impedance Stabilization Network (LISN) and Agilent Spectrum analyzer E-4411B. Conducted Emission levels were measured with and without RFI filter used in power supply section of the system. The Conducted Emission level was found to be around 50 dBV. With addition of RFI Filter, the Conducted Emission level found to be reduced by around 15 dB to 20 dB. These levels are compared with MIL-461E, FCC and CISPR Standards for Conducted Emission. GPS VTS Boards (GPRS/SMS Based) with RFI Filter could meet compatibility requirements with MIL461E, FCC and CISPR EMI/ EMC Standards for Conducted Emission. 
