Correlator design and implementation for GNSS receivers
2013 NORCHIP, 2013This paper shows how the correlator block for GNSS receivers can be analyzed and optimized. The received signal characteristics are reviewed and used in the optimization process. The correlator is a key element in the GNSS receivers and it takes a considerable amount of the chip area and power. It is shown that a gate-count reduction of 30% or more can

Acquisition strategies of GNSS receiver
International Conference on Computer Networks and Information Technology, 2011GNSS receiver performs many important operations out of which acquisition has the great importance. The performance of GNSS receiver is strongly influenced by the acquisition time. Acquisition provides rough estimate of code delay and Doppler frequency values of the received signal which plays very important role to synchronize local code with the ...

Method for Assessing the Interference Impact on GNSS Receivers
IEEE Transactions on Aerospace and Electronic Systems, 2011The definition of new families of curves named interference error envelope (IEE) and interference running average (IRA) is presented. Such tools are able to assess the impact of RF interference on different GNSS receivers, taking into account the features of the in-band interference source. In fact the actual impact on the final performance is strictly

Snapshot technology in GNSS receivers
2018 25th Saint Petersburg International Conference on Integrated Navigation Systems (ICINS), 2018Snapshot technology allows to make a short data record and process it to find the location rather than continuously tracking the signal. This is especially useful when data cannot be collected in a continuous manner. Receiver using snapshot technology makes short data records from a RF front-end, digitizes it and stores.

GNSS Receiver Reference Design
2008 4th Advanced Satellite Mobile Systems, 2008Satellite based navigation is a rapidly growing application of satellite systems. The research of the topic is lacking "open source" hardware receivers. Our group's purpose is to provide one. In this paper we outline the background to the topic, motivate the need for hardware receiver research and present the functional blocks for a generic GNSS ...
