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 MIL-461E, FCC and CISPR EMI/ EMC Standards for Conducted Emission. 

“…The different EMI/EMC, environmental and dynamic test shall be conducted on the system. HE-30 Enclosures were also designed for Model 2 with GPS VTS Transmitter / Receiver Boards and Radiated Emission test results conducted at national EMI test laboratory had been published in papers at reference [9,13] Similarly Aluminum (Alloy 6063) HE-09 Enclosure was designed for GPS VTS Model 1 and 2. The results for Radiated Emission measured with EMI Probes on Spectrum Analyser had been published in the paper at reference [14].…”

The EMI/electromagnetic compatibility (EMC) analysis is becoming very important in today's world of dense EMI environment. As we go toward accuracy and stability of any electronic product in dense EMI field, it is necessary to test it at printed circuit board (PCB) level. This paper describes the measurement technique of scanning of PCB using EMC Precision Scan Tool. The result of near-field measurement indicates the intensity of radiation of each component on PCB. This study is proposed to estimate the radiation field at component level. The near-field based techniques have been widely used in EMC studies because of the high accuracy and reliability. With appropriate model extraction and simulation tools, near-field scanning can be used to predict electromagnetic emissions. With proper shielding, the near-field radiations can be reduced. The near-field radiations can be used to predict far-field radiations from the system, before practically testing in EMI/EMC Laboratory or getting installed at end-user applications. Two models for global positioning system (GPS)-based vehicle tracking system used in research work have been proposed in this article. One is GPRS based and the other is SMS based, intended to be used in stringent environment and ground-based army vehicle. The near-field radiations have been taken at PCB level in dB µV for a range of 100 kHz-2.5 GHz frequency band. Maximum radiations of around 90-130 dB µV were found. The paper proposes Mu-metal and HE-30 shielding materials for mitigating low-and high-frequency radiations. The GPS VTS GPRS based board and GPS VTS SMS Tx board with HE-30 enclosures had been tested in national EMI Test Laboratory, Automotive Research Association of India (ARAI), for the frequency bands 100 KHz-2.5 GHz. The results had been compared with MIL-461E EMI/EMC standard, and had been found to be satisfactory. The low-frequency radiation level was found to be just within the acceptable limits as per the standard.
