Open Source Software Defined Radio Platform for GNSS Recording and Simulation

چکیده
The Software Defined Radio (SDR) platform continues to shape the Global Navigation Satellite System (GNSS) testing and development environment. Open source SDR platforms are now being developed and offer GNSS development capability to a variety of users that have not previously had sufficient resources to be engaged. An open source platform also offers many advantages in terms of customization and system development. NAVSYS has integrated GNSS waveforms into SDRs such as the Ettus ResearchTM USRPTM N210 and the Racelogic LabSat devices for use as inexpensive GNSS signal simulators. In this paper we show how an open source SDR platform can be used with GNU Radio open source architecture for building a GNSS signal simulator. We will also show how this can be integrated with NAVSYS GNSS Signal Architect® Simulator Software for a turnkey system to carry out multi-frequency/multicode generation with the option for users to update and modify the signal generation software.

A Novel Sampling Approach in GNSS-RO Receivers with Open Loop Tracking Method
Propagation of radio occultation (RO) signals through the lower troposphere results in high phase acceleration and low signal to noise ratio signal. The excess Doppler estimation accuracy in lower troposphere is very important in receiving RO signals which can be estimated by sliding window spectral analysis. To do this, various frequency estimation methods such as MUSIC and ESPRIT can be adopt...
