FIELD: radio engineering, communication.SUBSTANCE: to identify frequency, an optional or conditional parameter is linked with a satellite identification parameter, wherein frequency identification indicates the frequency value for frequency division multiple access (FDMA). Such an optional parameter is needed for satellites of the modern GLONASS system and/or near-future GLONASS system (e.g. GLONASS-M), but is not included/linked when considering next-generation GLONASS satellites, e.g. GLONASS-K satellites. In addition, signals supported by specific GPS system satellites can be indicated using general satellite identification.EFFECT: enabling use of the same parameters for any GNSS system in the context of an A-GNSS system without the need to introduce specific parameters for each GNSS system, optimisation of a satellite receiving signals for improving operating characteristics when minimising power consumption and ensuring future compatibility for modernisation of GLONASS.15 cl, 4 dwg, 2 tbl |
