What is the payload of a spacecraft?

What is the payload of a spacecraft?

‘Payload’ was originally a seafaring term for revenue-producing cargo on a ship. In space terms it refers to those elements of the spacecraft specifically dedicated to producing mission data and then relaying that data back to Earth.

What is payload in remote sensing?

Remote sensing payloads are sensors which are mounted on suitable platforms such as aircraft, balloon, rocket, satellite, or even a ground based sensor supporting stand to measure the reflected/emitted radiation from earth.

What is payload in CubeSat?

The payload is the part of the satellite that allows it to fulfil the mission for which it was designed. It’s the reason for the CubeSat’s existence.

What is bus and payload?

Spacecraft Bus and Payload Assemblies are the main infrastructure of a satellite. They support the attachment of all the satellite systems and are designed for the extreme launch and space environments.

Why is it called payload?

Payload (n.) also pay-load, 1917, from pay + load (n.). Originally the part of a truck’s (later an aircraft’s) load from which revenue is derived (passengers, cargo, mail); figurative sense of “bombs, etc. carried by a plane or missile” is from 1936.

What is payload in security?

In computer security, the payload is the part of the private user text which could also contain malware such as worms or viruses which performs the malicious action; deleting data, sending spam or encrypting data.

What’s a payload?

Definition of payload 1 : the load carried by a vehicle exclusive of what is necessary for its operation especially : the load carried by an aircraft or spacecraft consisting of things (such as passengers or instruments) necessary to the purpose of the flight.

What is a payload sensor?

The sensor payload “allows an optimal operating point for the major system parameters of performance, weight, power consumption and size, all at a competitive price,” says Adi Dar Executive Vice President and General Manager of Elbit Systems Intelligence and Electro-optics — Elop.

What are Smallsats and CubeSats?

Minisatellites are spacecraft with a mass of 100-500 kgs. CubeSats are the only class of smallsats with a more clearly defined standard. A CubeSat is made up of units – one unit is a 10x10x10 cm cube. The CubeSat is then defined by the numbers of units, such as 6U or six units.

What is CubeSat?

Cubesats are miniature satellites that have been used exclusively in low Earth orbit for 15 years, and are now being used for interplanetary missions as well. They were trying to help students gain engineering experience in satellites, which are traditionally expensive to build and launch.

What are the bus systems of a typical communication satellite?

As shown in Figure 3 below, a satellite bus typically consists of the following subsystems: command and data handling subsystem (C&DHS); communications subsystem (CS); electrical power subsystem (EPS); propulsion subsystem (PS); thermal control subsystem (TCS); attitude control subsystem (ACS) also known as guidance.

What is a transponder in satellite communication?

The term “satellite transponder” refers collectively to a transmitter-receiver subsystem on board the satellite that processes, amplifies and retransmits a range of frequencies (the transponder bandwidth) to another location/terminal/antenna on the earth.

What is the payload in a satellite?

The payload is what the satellite is for, namely the payload is what performs the functions desired of the satellite . In a nutshell, the payload is the communications antennas, receivers, and transmitters. The rest of the satellite , the bus, supports the payload by providing a structure, power, commanding, and telemetry,…

What does payload exactly mean in satellite electronics?

In satellite electronics it has been used to describe where the main electronic circuits are. A satellite comprises a support subsystem known as a bus and a subsystem responsible for providing the core functionality, known as the payload. The payload is the reason for the satellite being there .

What are payloads in term of spacecraft?

For a rocket, the payload can be a satellite, space probe , or spacecraft carrying humans, animals, or cargo. For a ballistic missile, the payload is one or more warheads and related systems; their total weight is referred to as the throw-weight .
