A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which is small CubeSats. Similar satellites can work together as a group, forming constellations. Because of the high launch cost to space, satellites are designed to be as lightweight and robust as possible.
Satellites are placed from the surface to orbit by launch vehicles, high enough to avoid orbital decay by the atmosphere. Satellites can then change or maintain the orbit by propulsion, usually by chemical or ion thrusters. In 2018, about 90% of satellites orbiting Earth are in low Earth orbit or geostationary orbit; geostationary means the satellites stay still at the sky. Some imaging satellites chose a Sun-synchronous orbit because they can scan the entire globe with similar lighting. As the number of satellites and space debris around Earth increases, the collision threat are becoming more severe. A small number of satellites orbit other bodies (such as the Moon, Mars, and the Sun) or many bodies at once (two for a halo orbit, three for a Lissajous orbit).
Earth observation satellites gather information for reconnaissance, mapping, monitoring the weather, ocean, forest, etc. Space telescopes take advantage of outer space's near perfect vacuum to observe objects with the entire electromagnetic spectrum. Because satellites can see a large portion of the Earth at once, communications satellites can relay information to remote places. The signal delay from satellites and their orbit's predictability are used in satellite navigation systems, such as GPS. Space probes are satellites designed for robotic space exploration outside of Earth, and space stations are in essence crewed satellites.
The first artificial satellite to be launched into the Earth's orbit was the Soviet Union's Sputnik 1, on 4 October 1957.
Hello po. May research po kami ulit ngayon. And medyo bago po sakin yung Research Paradigm, sa Conceptual Framework lang po ako medyo familliar.
Ano po ba yung Research Paradigm? Anong pinagkaiba nila? Quantitative (Corrrelational) po yung ginagawa kong research.
Nag try na po ako manood ng...
Agila: The First Satellite Dedicated to the Philippines
The Philippines is a country that consists of more than 7,000 islands, making it challenging to provide internet connectivity and other telecommunication services to its people. To address this problem, the Philippines has launched and...
Ask lang po sa mga expert dito, paano po makikita mga compatible ram/ssd/cpu para sa laptop na to? Gusto ko po sanang i upgrade para sa school work naman kasi bsit course po sana kukunin ko, ang specs po nya ngayon is motherboard pt10f, cpu intel core i3 3110m, 4gb ddr3 1600mzh, win10 balak ko...
Diba mga lods, pagdating sa mga modem na nka unluck ung admin ay pwede natin ma set kung anung band gusto natin gamitin ..
White mamba modem user ako
Pwede mkapagsabay ng dalawang band ung mamba para lumakas ung speed nito .. na try kona lahat i pares2x at the best partner is band 1 and band 3...
Ask ko lang sana if may idea kayo kung paano ko ma babypass yung Satellite internet connection sa barko namin, and since need pa mag log in sa account at limited lang kasi sa 1GB per Month, eh baka may nakaka alam. Patulong naman.
Metro Manila (CNN Philippines, May 27) — Elon Musk’s Starlink satellite internet service company has successfully registered in the Philippines.
In a statement Friday, the National Telecommunications Commission (NTC) said it has approved the registration of Starlink Internet Services...
tanong ko lng guys ano po ba purpose ng satellite dish ung nilalagay sa bubungan ?
kase dati naka connect ako sa kabilang net shop tapos medyo malayo d nako maka connect tinry namin ung satellite dish na luma naka konek naman kht malayo
gusto ko lng malinawan kung ano mga purpose nya
Totoo po ba yang PH Alliance Na po yan?
Na merong Free Trial 2 weeks daw ?
Parang Pishing Site kasi ng Bank Account ?
Thru satellite daw yung Internet Nila With IPTV40 ?
Baka natratrace na tayo ng globe dahil dyan sa nakalagay, baka si triangle ang way nila para malaman kung sino mga naka freenet na komukonek sa kanya, mga sir/maam , ano sa tingin nyo? Baka may bagong pakulo na naman si globobo
Last April 2017 pato nirelease but sa mga di pa nakakaalam at mahilig sa space, ito yung link ng mga pictures. Nice pang wallpaper sa desktop mo o kaya kung may projects ka sa science about earth, etc... :)
