Welcome to my homepage!
This page is under development and soon there should be added some GNSS and SDR related contents.
Over time I will also gradually transfer the information from our old GNSS SDR homepage to this homepage.
Adding Partial Support for SBAS to the SoftGNSS – Part1
In this set of articles I want to share my code which adds to the SoftGNSS GNSS SDR a partial support for SBAS signal processing – WAAS, EGNOS and SDCM. The support is only partial because this new code does only signal acquisition and tracking. The reason is that SBAS and GPS signals share the same family of … Continue reading Adding Partial Support for SBAS to the SoftGNSS – Part1
GPS, GNSS and Other Systems
Today the well-known GPS is just one of a few satellite based positioning systems. The American GPS (original name – Navstar) and the Russian GLONASS were the first systems of this kind. There were some satellite based systems before these, but they are obsolete and are not used today. Without a doubt the GPS became … Continue reading GPS, GNSS and Other Systems
GNSS Antennas
Depending on application (or price) a GNSS antenna may be a quite complicated device. The GNSS receiver performance may suffer significantly if the antenna is connected incorrectly or if the antenna is of a lower class than the receiver. In this brief article I will try to point to a few important points about GNSS antennas … Continue reading GNSS Antennas
A Small List of FPGA Boards
Here is my small list of not too expensive FPGA evaluation and other types of boards that can be used for SDR projects. I am mostly familiar with Xilinx products therefore the list consist mainly of boards based on Xilinx chips.
Pentek Software Defined Radio Handbook
This handbook is very much targeted at professional applications like mobile basestations equipment, military equipment and so on. But it also has some good overview of SDR basics which also apply for GNSS receivers, so I recommend to take a look at it.
