In this article, the authors use a vector tracking approach to convert a software receiver into a software transceiver, showing that this effort is both feasible and easily realized. The basic concept is presented with an accuracy assessment of the error sources and generated signal quality is compared to theoretical lower limits.

New legislation aiming to protect the privacy of internet and phone users could shield not just their browsing and buying habits but their location information as well.
The American Data Dissemination (ADD) Act, introduced by Sen. Marco Rubio on January 16, covers service providers that use the internet and “collect records” — a very broad definition. The Act will also be enforced against common carriers — that is telecommunications companies.

The navigation sensors for location-based services (LBS) are complex technical systems. Modern technical science can answer most questions about the optimality of particular position determination methods, signal processing algorithms, electronic circuits or similar well-defined problems, but the rigorous answer to the questions concerning the optimal LBS positioning sensor are still a big problem.
