GPS L2 (1227.60 MHz)

GPS L2C civilian signal · Carrier-phase GNSS for RTK surveying · Ionospheric correction (dual-frequency)

Frequency Range1227.60 MHz
Wavelength24.4 cm
ITU / Standard—

Applications

  • →GPS L2C civilian signal
  • →Carrier-phase GNSS for RTK surveying
  • →Ionospheric correction (dual-frequency)

Propagation Characteristics

Same orbital altitude as L1. Dual-frequency L1+L2 receivers can correct for ionospheric delay, enabling centimeter-level accuracy.

Regulatory Notes

RNSS protected band. L2C signal added on Block IIR-M satellites (2005+). Older Block II/IIA satellites transmit military P(Y) code only on L2.

Wavelength / Frequency

Convert between frequency, wavelength, and wave number in free space or medium. Calculate half-wave and quarter-wave lengths for antenna and transmission line design.

Link Budget

Calculate RF link budget: transmit power, free space path loss, antenna gains, and received signal level. Determine link margin and maximum range.

Patch Antenna

Calculate rectangular microstrip patch antenna dimensions (width, length) using the Transmission Line Model. Outputs effective dielectric constant, edge-feed impedance, and nominal gain for common substrates like FR4 and Rogers.
