Abstract

Abstract– GPS receivers provide very precise Pulse Per Second (PPS) signal. Designing a GPS receiver with low cost device to simulate a real time GPS scenario is a critical issue. Here, we use a simple low-cost method of time synchronization using RTL-SDR receivers to calculate the position. First, we show the data logged from RTL-SDR with both I and Q signal representation. Then, sky plot and both PLL and DLL data are represented and show the results after filtering. Finally, a precise location for the receiver is shown in UTM system.The Global Positioning System (GPS) is a Constellation of Earth orbiting satellites maintained by the US DOD for the purpose of defining geographic positions. The system transmits radio signals that can be used by GPS receivers to calculate position, velocity and time anywhere on earth, any time of day or night. The first Block I GPS satellite was launched in 1978 . The GNSS Galileo E1 and GPS L1 links are centred at 1575.42 MHz, and this band is covered by the E4000 tuner IC. The GNSS-SDR software receiver can be configured to use the RTL2832U as a real-time signal source, thus providing a low-cost option to build a real-time software-defined GPS L1 receiver .
