Methods

CalculateAngle(Antenna, Antenna)

Calculates the angle between this antenna and another antenna specified by the target.

protected double CalculateAngle(Antenna main, Antenna target)

Parameters

main Antenna

The main antenna

target Antenna

The targeted antenna

Returns

double

[deg] The pointing angle in degrees

CalculateBaudRate()

Calculates the baud rate of the signal for the transmitter

protected virtual double CalculateBaudRate()

Returns

double

[bytes ps] The transmitter baudrate

CanAccess(Vector3)

Returns whether the spacecraft is able to access another spacecraft. This will calcualte the line of sight value and determine if a line can intersect the other craft. This may be overriden by a base class with some values. http://paulbourke.net/geometry/circlesphere/index.html#linesphere

protected virtual bool CanAccess(Vector3 p2)

Parameters

p2 Vector3

Position of the link target

Returns

bool

A line of sight access to the other craft.

GetConnectionLength()

Gets the length of the connection between the transmitter and receiver

public double GetConnectionLength()

Returns

double

[m] The length of the connection

GetRecentMessage(bool)

Returns the current output message from the system. Once read, it will be removed from the link block.

public TelemetryPacket? GetRecentMessage(bool pop = true)

Parameters

pop bool

A flag whether to pop the message off the list

Returns

TelemetryPacket

The most recent message (if it exists)

GetTransmissionAccess()

Overriden function that returns whether a specific transmission type is able to access the connection between receiver and transmitter.

protected virtual bool GetTransmissionAccess()

Returns

bool

An access flag
