The following labels for data contained in the Matlab struct 'iedata' in the
file 'interferenceEventData.mat', correspond to an interference event captured
in wideband raw samples during an interval lasting just over 2 seconds beginning
at approximately (GPS week: 2405, GPS second of week: 279407.9) on February 11,
2026.


TRO_ECEF ----- ECEF position of the TRO station antenna in meters.

NLR_ECEF ----- ECEF position of the NLR station antenna in meters.

noradIdVec --- Nsats-by-1 vector of NORAD identifiers for objects designated as
               either "payload" or "unknown" and having a TLE that was published
               within +/- 7 days of the interference event.

svVelVec ----- Nsats-by-1 vector of satellite velocities in meters/sec relative
               to ECEF and expressed in ECEF.  These velocity values can be
               considered approximately constant over the ~2-second capture
               interval.

tTGTVec ------ Nmeas-by-1 vector of true GPS timestamps for the corresponding
               the T/FDOA measurement pair, in GPS seconds of week for week
               2405.  This timestamp is the absolute time assumed for the TRO
               station in the TDOA measurement.

tdoaVec ------ Nmeas-by-1 TDOA measurement in seconds (t_TRO - t_NLR)
               corresponding to the measurement times in tTGTVec.

fdoaVec ------ Nmeas-by-1 FDOA measurement in Hz (f_TRO - f_NLR) corresponding
               to the measurement times in tTGTVec.

lambda ------- Approximate wavelength of the interference signal, in meters.

svPosCell ---- Cell array with Nmeas elements.  The kth element of the cell
               array is an Nsats-by-3 matrix of satellite positions in meters in
               the ECEF coordinate frame at the kth measurement epoch.

svPosElMaskCell ---- Like svPosCell but limited to the satellites in
                     satElMaskVec.

noradIdMaskVec - Nd-by-1 vector of NORAD IDs of the satellites that satisfied a
                 0-degree elevation mask with respect to all IGS stations that
                 detected interference during the event.
