... pattern and a 30 kHz frequency offset to minimize periods of worst-case in- terference with satellite signals. Another paper [14] proposed yet another pulse pattern and an extended-length pseudorandom ... Although this offset was expected to virtually eliminate interference with the satellite signals, Gary McGraw at Rockwell later showed that the reduction in worst-case cross-correlation is...
