A software-defined GPS and Galileo receiver a single-frequency approach by K Borre ( )
7 editions published in 2007 in English and held by 47 WorldCat member libraries worldwide
This book and companion DVD provide hands-on exploration of new technologies in the rapidly growing field of satellite navigation receivers. One of the unique features of the work is the interactive approach used, giving readers the ability to construct their own Global Navigation Systems (GNSS) receivers. A complete GPS software receiver implemented using MATLAB code as well as GPS and GIOVE-A signal recordsâ??available on the companion cross-platform DVDâ??allows readers to change various parameters and immediately see their effects
A software radio approach to global navigation satellite system receiver design by Dennis M Akos ( )
2 editions published in 1997 in English and held by 3 WorldCat member libraries worldwide
GPS Software Radio. Direct RF Sampling Research by Dennis M Akos ( Book )
2 editions published in 2002 in English and held by 2 WorldCat member libraries worldwide
The future satellite positioning navigation systems will provide civil signals on multiple frequencies, similar to that currently available only for the military pie. The multiple distinct frequencies will provide many advantages to users of the navigation systems. This report presents the development of a direct RF sampling front end design well suited for multiple frequency satellite navigation receiver design. No frequency down conversion is necessary, rather the particular frequency bands of interest are intentionally aliased using a wide band Maxim 104 analog-to-digital converter (ADC). The resulting samples are passed, via a buffering FPGA design, to the memory space of a host PC for storage as well as eventually processing of the multiple frequency transmission. This paper describes the design of the front-end, validates its concept with collected data. The system designed was demonstrated at Wright Labs and the developed hardware configuration/software was transferred was their use
A hybrid modulation for the VHF aeronautical channels by Dennis M Akos ( )
2 editions published in 1992 in English and held by 2 WorldCat member libraries worldwide
A comparison of direct radio frequency sampling and conventional GNSS receiver architectures by Mark Lockwood Psiaki ( )
1 edition published in 2005 in English and held by 1 WorldCat member library worldwide
A Comparison of "Direct RF Sampling" and "Down-Convert and Sampling" Global Positioning System (GPS) Front End Receiver Architectures ( )
1 edition published in 2004 in English and held by 1 WorldCat member library worldwide
This report presents the final results of an investigation into direct radio frequency (RF) sampling receiver front ends and compares their performance to the traditional digital receiver front end designs. The distinction between the two implementations is that a direct RF sampling front end uses no analog frequency down conversion, rather the information bandwidth is aliased through the sampling process. This type of design significantly simplifies multiple frequency receiver design, important for receivers used in the Global Positioning System. However, the consequences of such an architecture are not fully understood as the technology required for their implementation has only recent become available. Past work has shown the feasible of the approach. This effort and report document the impact on the resulting phase noise, an important element in receiver design, as a result of the direct RF sampling
