RF recordings of GPS SVN49 broadcasting non-standard codes
Creators
Description
This dataset consists of several recordings of the L1 signal broadcasted by GPS
SVN49 between 2019-06-26 and 2019-06-28. This satellite broadcasts a
non-standard code as its L1 C/A signal, where the usual spread-spectrum PRN is
replaced by a PRN which consists of alternating zeros and ones (akin to a square
wave subcarrier). This produces strong spectral lines at +/-511.5kHz from the L1
centre frequency.
The signal is modulated with a navigation message in the usual way using 50baud
BPSK.
The recordings have been made with a LimeSDR using an external 10MHz GPSDO and a
small and inexpensive GPS patch antenna.
Included files
The .bin files contain waterfall data generated with STRF. This
data can be used to identify the satellite producing the signal using Doppler
measurements.
The mjd58660.dat file contains Doppler measurements extracted with STRF.
The .c64 files are IQ recordings of the upper sideband of
the modulation (centred at L1 + 511.5kHz). One of them is done at 5ksps and
another at 10ksps. The timestamp of the start of each recording is indicated in
the filename. The format is complex IQ data as 32-bit floats.
