struktura signala sistema GPS v frekvenčnem pasu 1559-1610 MHz z žariščem pri 1575,42 MHz je binarna modulacija s faznim zamikom (Binary Phase Shift Key ali BPSK) s kodno hitrostjo 1,023 Mcps; modulacija BPSK s kodno hitrostjo 10,23 Mcps; in modulacija BOC z 10,23 MHz frekvenco podnosilca in kodno hitrostjo 5,115 Mcps in močjo signala, kot je opisano v spodaj navedenem dokumentu »Referenčne predpostavke za analizo združljivosti sistemov GPS/Galileo«; v prihodnosti se modulacija BOC (1, 1) z žariščem pri 1575,42 MHz doda tej strukturi signala.
The GPS signal structure in the 1559-1610 MHz band, centred at 1575.42 MHz, will be a Binary Phase Shift Key (BPSK) modulation with a code rate of 1.023 Mcps; a BPSK modulation with a code rate of 10.23 Mcps; and a BOC modulation with a 10.23 MHz sub-carrier frequency and a code rate of 5.115 Mcps, and a signal power as specified in the document, referred to below, entitled »Reference Assumptions for GPS/GALILEO Compatibility Analyses.« In the future, a BOC (1, 1) modulation centred at 1575.42 MHz will be added to this signal structure.
