generate binary sequences has been proposed independently by V. M. Sidelnikov and A. Lempelet alia(see Additional Resources). The binary sequence derived from their methods will serve as a generative one for our new PRN code family. From here on, this column will refer to these asSLCE ...
that options for 2 Hz and 5 Hz have just been added] According to the datasheet, the F9P has a maximum RTK position output of 7 Hz when running with all four GNSS constellations but for this experiment I left it at 5 Hz which I find an adequate sample rate for most applications. ...
GNSS and Aviation The UniTaS IV Project investigates technologies and methods to improve the practical use of satellite navigation in aviation. Hence integrity, continuity, and availability of navigation aids are a major focus of the project.
