GPS M’-Code and P-Code Signal Simulation Using an Open Source Radio Platform
نویسنده
چکیده
Current generation military simulators are expensive, increasing costs for GPS test and evaluation for military GPS user equipment developers. Inexpensive commercial GPS simulators are available that use signal simulation, record and playback techniques to test receivers under representative environment, but these commercial record and playback GPS simulators do not have the bandwidth needed to collect or simulate military GPS signals. NAVSYS’ military version of the GNSS Signal Architect software, combined with their implementation of a full bandwidth record and playback capability with their GNSS Signal Generator provides an inexpensive test and evaluation tool for Y, M, P and C/A code (YMCA) receivers. The design of this product is presented in this paper with test results showing its performance with a GPS receiver.

Design and Implementation of GPS signal Generator using c/a code on FPGA: A Review
The aim of this project is to implement and develop a platform that allows developing a GPS software receiver using available signal processing techniques. This allows testing and implementing a new algorithm which also permits to upgrade the receiver easily to new signal structures or even other navigation systems. In this project we developed Coarse/Acquisition (C/A)) code generator of GPS re...
متن کاملDesign 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...
متن کاملGPS TOOLBOX An open source GPS multipath simulator in Matlab/Octave
Multipath is detrimental for both GPS positioning and timing applications. However, the benefits of GPS multipath for reflectometry have become increasingly clear for monitoring soil moisture, snow depth, and vegetation growth. In positioning applications, a simulator can support multipath mitigation efforts in terms of, e.g., site selection, antenna design, receiver performance assessment, and...
متن کاملDesign and Simulation of Photoneutron Source by MCNPX Monte Carlo Code for Boron Neutron Capture Therapy
Introduction Electron linear accelerator (LINAC) can be used for neutron production in Boron Neutron Capture Therapy (BNCT). BNCT is an external radiotherapeutic method for the treatment of some cancers. In this study, Varian 2300 C/D LINAC was simulated as an electron accelerator-based photoneutron source to provide a suitable neutron flux for BNCT. Materials and Methods Photoneutron sources w...
