Benefits of Software GPS Receivers for Enhanced Signal Processing

نویسنده

  • Alison Brown
چکیده

In this paper the architecture of a software GPS receiver is described and an analysis is included of the performance of a software GPS receiver when tracking the GPS signals in challenging environments. Results are included which demonstrate the advantage of the software GPS receiver in tracking the GPS signals in low signal-to-noise or jamming scenarios. Various current and previous applications of the software GPS receiver are also described.

Software Rake Receiver Enhanced Gps System

Acceleration of semiconductor technologies has enabled incorporation of GPS receivers in small inexpensive hand held battery operated devices. As the size of chipsets for different communication protocols diminishes in size, building multi-protocol communication systems including GPS receivers has become not only attractive but also possible. A limitation of current approaches requires the Base...

A Novel Interference Rejection Method for GPS Receivers

This paper proposes a new method for rejecting the Continuous Wave Interferences (CWI) in the Global Positioning System (GPS) receivers. The proposed filter is made by cascading an adaptive Finite Impulse Response (FIR) filter and a Wavelet Packet Transform (WPT) based filter. Although adaptive FIR filters are easy to implement and have a linear phase, they create self-noise in the rejection of...

GPS Jamming Detection in UAV Navigation Using Visual Odometry and HOD Trajectory Descriptor

Auto-navigating of unmanned aerial vehicles (UAV) in the outdoor environment is performed by using the Global positioning system (GPS) receiver. The power of the GPS signal on the earth surface is very low. This can affect the performance of GPS receivers in the environments contaminated with the other source of radio frequency interference (RFI). GPS jamming and spoofing are the most serious a...

Design and Implementation of GPS signal Generator using C/A code on FPGA

The Global Navigation Satellite System (GNSS) plays an important role in positioning and navigation applications. The Global Positioning Service (GPS) augmentation is to achieve more reliable and accurate navigation solutions. The presently available traditional GNSS receivers are hardware based receivers which are not flexible and cannot be easily upgraded to acquire the signals from other GNS...

A Python Software Platform for Cooperatively Tracking Multiple GPS Receivers

Existing software platforms are not well suited to the task of processing data from a network of GNSS receivers. Because data are expected to be shared amongst networked receivers, not only must new algorithms be designed, but new software platforms upon which these algorithms can be tested must also be built. In this work a software platform for simultaneously processing data from many GNSS re...
