Communication Systems - ephemerista.comms.systems

The systems.py module.

This module provides the CommunicationSystem class.

pydantic model ephemerista.comms.systems.CommunicationSystem

The CommunicationSystem class.

This class composes the Antenna, Receiver, and Transmitter classes to form a model of full communication system. To instances of compatible communication systems are required to compute the properties of a link between the two systems.

Fields:

• antenna (AntennaType)

• channels (list[uuid.UUID])

• receiver (ReceiverType | None)

• system_id (uuid.UUID)

• transmitter (ephemerista.comms.transmitter.Transmitter | None)

field antenna: TypeAliasType [Required]

field channels: list[Annotated[UUID]] [Required]

field receiver: TypeAliasType | None = None

field system_id: Annotated[UUID] [Optional] (alias 'id')

Constraints:

• uuid_version = 4

field transmitter: Transmitter | None = None

carrier_power(rx, losses, rng, tx_angle, rx_angle)

Return type:

float

carrier_to_noise_density(rx, losses, rng, tx_angle, rx_angle)

Calculate carrier-to-noise density in dBHz.

Return type:

float

carrier_to_noise_interference_density(rx, losses, rng, tx_angle, rx_angle, bandwidth, interference_power_w)

Calculate carrier-to-noise interference density in dBHz.

Return type:

float
