func SerializeRnxNav4 

func SerializeRnxNav4(w io.Writer, epochMap observation.EpochMap, gnssSet *observation.Set, outputSettings OutputSettings) (err error)

SerializeRnxNav4 writes a ephemeris.Ephemeris as RINEX 4 to the provided io.Writer interface.

func SerializeRnxObs2 

func SerializeRnxObs2(w io.Writer, epoch observation.Epoch) (err error)

func SerializeRnxObs3 

func SerializeRnxObs3(w io.Writer, epochMap observation.EpochMap, gnssSet *observation.Set, outputSettings OutputSettings) (err error)
