The miniaturized satellite is a device orbiting earth having smaller physical measurements and lower mass than the regular satellite like the geostationary satellite. The miniaturized satellites have turned out to be progressively normal recently. They are appropriate for use in restrictive wireless communication systems, and additionally for information gathering, scientific observation and the Global Positioning System (GPS).
These satellites are frequently placed in lower orbits of earth and are propelled in groups known as "swarms." In this kind of system, every satellite works in a way same as a repeater in a system of cellular communications. Some of these satellites are placed in elongated (elliptical) earth orbit.
Miniaturized satellites can be categorized on the basis of weight in pounds (lb) or mass in kilograms (kg). The mass of a microsatellite (or microsat) is in between 10 kg and 500 kg, the weight is in the range of 22 pounds (lb) to 1100 lb. The mass of nanosatellite (or nanosat) is in between 1 kg and 10 kg (2.2 lb and 22 lb). While the mass of picosatellite (or picosat) is under 1 kg (2.2 lb).
The miniaturized satellites have numbers of advantages over the traditional satellites, some of them are;
- Manufacturing cost is lower
- Simplicity of large scale manufacturing
- Launching cost is lower
- Capability to be propelled in groups or "piggyback" alongside bigger satellites
- Minimum financial losses in case of failure
Traditional Satellite Challenges
Cost is the greatest challenge with the traditional satellites that weigh a couple of thousand pounds and have added up to the cost of launch in the range of $100-200 million, with deployment and launch costs being very significant. The expense per pound of the payload for a normal propel system ranges from $3200 per lb for a Low Earth Orbit (LEO) deployment, or near about $5500 per lb for a Geostationary Transfer Orbit (GTO). A deployment GTO is ordinarily used to change satellites into a high Geostationary Orbit that positions the satellite in a fixed position as for a ground station. The traditional satellites are additionally costly to construct, which results in an auxiliary cost. A simple satellite costs in the range of $50-400 million relying upon functionality.
Limited number of launch facilities is also a challenge for this industry.
Due to the high prices and restricted facilities, the technology of traditional satellite has solely seen borderline developments in potency over the previous few decades. The possible solution to the current downside involves the miniaturization and commoditization of technology of satellite to create them has above mentioned advantages.
The miniaturized satellites might create satellites more cost-effective by reducing the price of deployment per pound, and also by decreasing the dimensions of the particular satellites, number of satellites may be deployed with one launch. Miniaturized satellites provide economies of scale in terms of the manufacturing of the device and in its deployment it the orbit.
