SX3 GPS/GALILEO/GLONASS/BEIDOU/QZSS/IRNSS SOFTWARE RECEIVER
– Real-time capable on COTS PC hardware when simultaneously tracking all current civil SIS signals of GPS, Galileo, GLONASS, BeiDou, QZSS, SBAS and IRNSS systems (using 8 IF input streams at a sample rate of 20 MHz each)
– Adaptable configurations enabling real-time full featured reference station mode on COTS PC hardware
– Recorder functionality to store data files for later post-processing
– Entire configurability provided within the graphical user interface (including online configuration parameter description within GUI)
– Live configurability for dedicated parameters as DLL, FLL and PLL bandwidths
– Dedicated widgets for PVT solution, RF-spectrum, multi-correlator output, GNSS channel output, acquisition output, …

REAL-TIME MULTI-CORRELATOR
– Continuous real-time visualization of the correlation function within Doppler and code domain or time and code domain for all tracked GNSS (BPSK, BOC, AltBOC) signals
– User definable correlator spacing and integration times
– Long multi-correlator integration times possible due to navigation-bit removal
– Multipath and spoofing detection possible via analysis of correlation values
– Data logging for post analysis provided
POST-PROCESSING DATA ANALYSIS
– Data logging for intermediate data of various signal processing steps, e.g. acquisition data logs, channel dump logs (including NCO data, discriminator values and IQ data), decoded navigation data bits and much more
– Additional MATLAB tools for further data analysis come along with the SX3 delivery
– Standard outputs as RINEX 2.11 and RINEX 3
APPLICATION PROGRAMMING INTERFACE
– C -language based SX3 API framework provided to implement user defined algorithms
– User is free to add, replace or expand capabilities of the SX3 software receiver due to the access to receiver’s internal data
– Seamless loading of user generated DLL files at receiver runtime (in real-time and post processing mode)
– Full debug capabilities for users within their self defined source code
– Due to DLL concept different partners can contribute to dedicated developments without any need to disclose the source code to each other
SIGNAL QUALITY MONITORING
– Signal Quality Monitor to verify the shape of the correlation function
– Signal Power Monitor to detect anomalous signals
– Code Carrier Divergence Monitor to check code/carrier divergency
– Measurement Quality Monitor performing pseudo-range measurement tests
DUAL RF-INPUT
– Dual RF-input operation mode provided by IFEN’s SX3 hardware frontend including full integration within the SX3 software receiver
– Attitude determination systems and reflectometry systems are available as options
– User defined algorithm development for dual RF-input systems possible in conjunction with the API functionality
