}

Antenna is a GNSS antenna.

func (Antenna) Equal

func (ant Antenna) Equal(ant2 *Antenna) bool

Equal reports whether two antennas have the same values for the significant parameters.

type ByPRN

type ByPRN []PRN

ByPRN implements sort.Interface based on the PRN.

func (ByPRN) Len

func (p ByPRN) Len() int

func (ByPRN) Less

func (p ByPRN) Less(i, j int) bool

func (ByPRN) Swap

func (p ByPRN) Swap(i, j int)

type PRN

type PRN struct {
	Sys System // The satellite system.
	Num int8   // The satellite number.

}

PRN specifies a GNSS satellite.

func NewPRN

func NewPRN(prn string) (PRN, error)

NewPRN returns a new PRN for the string prn that is e.g. G12.

func (PRN) String

}

Receiver is a GNSS receiver.

func (Receiver) Equal

func (recv Receiver) Equal(recv2 *Receiver) bool

Equal reports whether two receivers have the same values for the significant parameters. Note for STATION INFOTMATION files: Some generators do not consider the receiver firmware for this comparision, e.g. EUREF.STA.
