# What is space segment in satellite communication?

## What is space segment in satellite communication?

The space segment of an artificial satellite system is one of its three operational components (the others being the user and ground segments). It comprises the satellite or satellite constellation and the uplink and downlink satellite links.

A satellite link is defined as an Earth station – satellite – Earth station connection. The Earth station – satellite segment is called the uplink. The satellite – Earth station segment is called the downlink.

### What are the two main segments of satellite communication?

Satellite communication has two main components: the ground segment, which consists of fixed or mobile transmission, reception, and ancillary equipment, and the space segment, which primarily is the satellite itself.

Which parameter should be calculated for designing a satellite link?

The parameters needed to be calculated in the inter-satellite link budget include: The transmission power of the sending end, the link information rate and the antenna aperture of the receiving end (Huang et al., 2012). In making link budget, some sheets are created by using calculator or Excel.

#### What is space and ground segment?

A ground segment consists of all the ground-based elements of a spacecraft system used by operators and support personnel, as opposed to the space segment and user segment. The ground segment enables management of a spacecraft, and distribution of payload data and telemetry among interested parties on the ground.

What are the different segments in satellite architecture explain?

A satellite communication consists of mainly two segments. Those are space segment and earth segment. So, accordingly there will be two types of subsystems namely, space segment subsystems and earth segment subsystems.

## What is the need of satellite link design?

The design of satellite link is quite important as it The design of satellite link is quite important as it gives the estimate of power that the satellite would be able to receive from transmitting earth satellite & power received from satellite repeater by the receiving earth station.

How do you create a satellite link?

Satellite Communication Link Design Procedure: 1. Determine the frequency band in which system must operate. Comparative designs may be required to help make the selection. 2.

### What is space segment and ground segment?

How does space segment work?

The main functions of the Space Segment are to transmit radio-navigation signals, and to store and retransmit the navigation message sent by the Control Segment. These transmissions are controlled by highly stable atomic clocks on board the satellites.

#### On what factors design of satellite link depends?

It has been experienced that the factors, which influence system design in satellite communication are the choice of frequency band, atmospheric propagation effects and multiple access technique.

What are satellite ground systems?

Components of Space Ground Systems Space ground systems are made up of several primary components including Ground Stations, Mission Control Centers, Ground Networks, Remote Infrastructure, and Launch Facilities. These components work together to enable management of spacecraft, payload data, and telemetry.
