Design of LNA assembly for GSP repeaters

Abstract

Global Positioning System (GPS) is a space-based radio navigation system, consisting of 24 satellites and ground support. GPS provides users with accurate information about their position and velocity, as well as the time, anywhere in the world. There is a little problem with GPS system that it has a poor reception inside the buildings and other covered structures. As GPS is becoming a part of daily life there is a requirement that user should access GPS inside the buildings and covered structures. The main purpose of a GPS repeater is to pickup signal from the satellite and after amplification the signal is retransmitted inside the building. Our design will be in L2 band of GPS(1.5 GHz) consisting of a receiving antenna, low noise amplifier, power amplifier and a reradiating indoor antenna to make the feeble signals strong for reception by any GPS receiver.
