Functions

func GetRinexSignalIDFromCode added in v0.22.0 

func GetRinexSignalIDFromCode(sys System, code string) (id int, err error)

GetRinexSignalIDFromCode returns the Signal ID for a given GNSS system and signal code. This function uses RINEX 4.02 signal IDs for availability computation.

func GetSignalIDFromCode added in v0.21.6 

func GetSignalIDFromCode(sys System, code string) (id int, err error)

GetSignalIDFromCode returns the Signal ID for a given GNSS system and signal code. This function uses RTCM3 DF395 signal IDs.

Types

type Signal added in v0.21.6 

type Signal struct {
	// Code (e.g. "1C")
	Code string
	// Freq [MHz]
	Freq float64
}

Signal represents a GNSS signal

func (Signal) Wavelength added in v0.21.6 

func (signal Signal) Wavelength() (wl float64)

Return the wavelength [m]

type SignalMap added in v0.21.6
