Glonass Gps Frequency Bands. 117645 MHz with a bandwidth of 125 MHz. All GLONASS satellites transmit the same code as their standard-precision signal. The multiple access technique used by GPS is CDMA whereas GLONASS uses FDMA. Ein Beispiel ist der Broadcom BCM47755 Chip der GPS GLONASS BeiDou das chinesische GNSS QZSS das japanische GNSS und GALILEO sowie zwei Frequenzen L1 L5 verwenden kann.
The first is L1 1602 MHz in which the separation between individual carriers is 05625 MHz. These bands were allocated to Radio. With the full GLONASS constellation the band. 12429375 MHz to 1248625 MHz. The GLONASS GNSS solution operates in the following frequency bands. The GLONASS transmissions in the band 16106 - 16138 MHz degraded radio astronomical observations dramatically in the years since the launch of the first GLONASS satellites.
GPS Technology operates in the following frequency bands.
The second is L2 1246 MHz in which the separation between individual carriers is 04375 MHz. GLONASS uses carriers in three areas. Each GLONASS system SVs Glonass and Glonass-M transmits navigational radiosignals on fundamental frequencies in two frequency sub-bands L1 16 GHz L2 125 GHz. On the L2 band between 1240 MHz and 1260 MHz the center frequency is determined by the equation 1246 MHz n 04375 MHz. The three GLONASS L bands have a range of frequencies to assign to satellites. Eine deutliche Steigerung der Genauigkeit ist erst dann zu erwarten wenn in Zukunft Chips zum Einsatz kommen die mehrere GNSS und mehrere Frequenzen unterstützen.
