    Design and development of SiGe HBT based high gain amplifier for GPS application
    (2008) Soni, B.; Ramasubramanian, R.; Sancheti, S.
    A two stage high gain small signal amplifier for GPS based receiver application is designed and realised using SiGe Hetrojunction Bipolar transistor (HBT). The measured gain and noise figure is 33.5 dB and 2.9dB respectively at Vce of 2 V, and total current of 10mA. The circuit is fabricated on microstrip configuration using RT duroid substrate of dielectric constant 10.5 and height 50 mils. This circuit is being used in satellite based GPS receiver. © 2008 IEEE.

    An android GPS-based navigation application for blind
    (Association for Computing Machinery, 2014) Nisha, K.K.; Pruthvi, H.R.; Hadimani, S.N.; Guddeti, G.R.M.; Ashwin, T.S.; Domanal, S.G.
    Visual Impairment makes the person depend on another person for all his works and daily chores. Through the application proposed in this paper, we aim to eliminate this dependency of a visually impaired person when travelling from one place to another. The main goal is to provide information regarding the current location, how much distance and time is required to reach the destination as well as provide the user with the directions and turns to be taken while travelling by providing continuous audio feedback in his understandable language. © is held by the author/owner(s).

    Empowering Women's Safety with smart IoT Technology: A Robust Protection System
    (Institute of Electrical and Electronics Engineers Inc., 2023) Ramesh, N.V.K.; Alaparthi, A.; Sai Charan, G.; Settipalli, R.; Velga, P.; Vani, B.V.
    Nowadays, women's safety has emerged as one of the world's most pressing issues, and crime against women has significantly increased nationwide. The frequency of auto theft and accidents has increased significantly as compared to the previous decade. The value of a human life exceeds all other values, and it is more crucial to seek assistance when you do so than to provide a helping hand. Every day, women from all walks of life struggle to maintain their safety and defend themselves. In the presence of insensitive guys who regularly harass, assault, and violate the dignity of women, and in front of their wandering eyes. Public transport, especially public places, has become hunter territory. For these atrocities that women undergo current scenario A clever wearable safety tool for girls primarily based totally at the Internet of Things is being implemented. It consists of a Arduino, Camera and a buzzer, and a button to activate the service. This unit is very remote and with the click of a button, it is activated by the victim when attacked, retrieves their current location and captures images of the victim Attacker via Esp32 Cam Module. A predetermined contact number will receive both the taken image and the location link. It monitors through the victim's smartphone and avoids the usage of additional hardware or modules, keeping the device compact. Live video streaming is via webcam and live Position is obtained by GPS module. This paper makes a collision avoidance and detection systems. There are numerous initiatives being taken with the goal of saving lives. The proposed study intends to develop an IoT-based security system that prioritises protecting women. © 2023 IEEE.

    On Cryptographic Approaches for Detecting GNSS Spoofing Attacks
    (Institute of Electrical and Electronics Engineers Inc., 2024) Ramalingam, J.; Maned, V.R.
    The increasing adoption of technologies dependent on Global Navigation Satellite Systems (GNSS) services has prompted many countries to develop their own navigation, positioning, and timing (PNT) systems. Spoofing GNSS signals is a significant security issue as it can undermine the reliability of GNSS positioning and timing services. In this paper, we analyze the efficacy of the Navigation Message Authentication (NMA) schemes proposed for GPS (USA) and Galileo (Europe). We demonstrate the ineffectiveness of the Chameleon hash key-chain proposed for GPS signal authentication and establish that standard digital signatures offer better performance than Chameleon hash key-chain in this context. © 2024 IEEE.
