Types

type Kind

type Kind int

The kind of controll message that can be exchanged between satellites and the ground-station.

const (
	KindInvalid      Kind = iota
	KindOzoneLevel        // Messages of this kind contain an ozone reading for the current location.
	KindAdjustCourse      // Messages of this kind contain a new target location of a satellite.
)

type Location

type Location struct {
	Lat float64 `json:"lat"`
	Lng float64 `json:"lng"`
	Alt float64 `json:"alt"`
}

func (*Location) Distance

func (l *Location) Distance(loc Location) float64

Distance calculates the distance between two locations in km. Altitude is not taken into account.

type SpaceMessage

type SpaceMessage struct {
	Kind Kind `json:"kind"`

	SenderID int

	Location   Location `json:"loc"`
	OzoneLevel float64  `json:"ol"`
	Timestamp  time.Time
}

func (*SpaceMessage) MarshalSpaceMessage

func (m *SpaceMessage) MarshalSpaceMessage() ([]byte, error)

func (*SpaceMessage) UnmarshalSpaceMessage

func (m *SpaceMessage) UnmarshalSpaceMessage(data []byte) error

type SpaceMessageMarshaler

type SpaceMessageMarshaler interface {
	MarshalSpaceMessage() ([]byte, error)
}

Messages are really just marshalled into JSON when transmitted over the network.

type SpaceMessageUnmarshaler

type SpaceMessageUnmarshaler interface {
	UnmarshalSpaceMessage([]byte) error
}
