A Satellite Platform and Integrated Wireless Sensor Systems

How Satellite Platforms Make Use of Integrated Wireless Sensor Systems

WSNs are Abstract Wireless Sensor Networks with multi-hop self-organizing networks that include many node numbers with environmental measuring. They have wireless communications for a satellite platform and data processing that collect and apprehend the process of information when it comes to achieving the defined tasks. Using WSNs gets to adapt to Space and Solar-system missions, outlining how SB-WSNs (Space-Based Wireless Sensor Networks) are working. There are distributed spacecraft missions and different platforms used for the purposes mentioned above, as well as for communication between space-based networks and ground infrastructure. Because of the large distances between inter-spacecraft, there’s a transceiver with a single half-duplex. This technique presents derivation between activation of the link schedule and the routes that are used for the most efficient traffic relay that takes place throughout a network.

What’s Satellite Platform & How Is It Used?

A satellite platform is a bus hosting any electronic equipment, such as radars, sensors, infrared imagers, and onboard computers. Depending on platform type, it can have multiple purposes, from weather monitoring and sending alerts about natural disasters to ensuring communication, i.e., broadband Internet or radio broadcasts. Sensors installed on these platforms can be used either for emergency analysis or for ensuring the satellite’s safe operation in orbit. 

What Are WSNs Used For?

WSNs have been used so far in many fields for building satellite platforms and sensors. A satellite platform definition is vast because these platforms can be used for monitoring, geographical routing, and commercial agriculture. Most platforms have wireless sensor networks with nodes that share effective information with one another, so all information is transmitted to ground stations that analyze data from space platforms. 

Today, many satellite communication systems are based on radar sensor systems. There are broadband applications and all sorts of multimedia services that are continuously developing and improving. If you want the spectrum energy to be improved, there’s the cognitive (CR) that’s exploiting how a spectrum is shared in terrestrial networks for over 10 years as the main approach. This shows promise for SatCo. In a network like SatCom, the CR can have used in satellite networks and in integrated satellite-terrestrial networks.

Explaining the Wireless Sensor System

So, what is a wireless sensor system, and how is it used in spacecraft platforms? The basic logic is that the higher the transmitting capacity of satellite networks, the vaster the cognitive network for an efficient resource. It’s important to understand the sensing-based spectrum that makes the integrated wireless sensor more dynamic. It’s important to maximize how a satellite user’s ergodic capacity functions when there’s interference with primary users terrestrially located at an average, acceptable level. First, it’s important to understand how any user of cognitive satellites is monitoring the user who is terrestrially located and uses the wireless sensor network. After, the power that arrives via sensing results is adjusted. If a user located terrestrially happens to be busy, then the user of the satellite is accessing the channel with the power that arrives.

The sensing-based cognitive terrestrial satellite network and the integrated wireless sensor act in a sink node when the wireless sensor network is gathering information to transmit the data through the satellite network. In the meantime, there’s the satellite user that uses a cognitive SU with the satellite network that’s located terrestrially. After, the power that comes through the sensing-based system of the cognitive satellite located terrestrially makes it easier for the sensing scenario to access the cognitive satellite via the intelligent schemes of the channel. The satellite user’s ergodic capacity is used for the evaluation of how the scheme is performing. And now, the average power of interference is constraining the satellite user to constrain the power that interferes with the user located terrestrially.

Should the Satellite Platform Be Used for the Integrated Wireless Sensor Systems?

So, how to use a satellite platform? This article has tried to explain how the integrated wireless sensor systems can be connected to a satellite platform, but the actual applications can be far more diverse. However, any platform integration must be made progressively. Integrated wireless sensor systems need a satellite platform to communicate with the terrestrial user so that communication is established. Power needs to be constrained so that the systems don’t break, and they must be in place. Putting up any system is not possible in chaotic conditions. 

Most importantly, any satellite platform must be assembled with space mission goals in mind. Depending on what satellite platforms are expected to — monitor weather, take pictures of agricultural lands, watch out for changing sea levels — the onboard equipment of a given spacecraft platform will differ.
