*IBYIGOJURU BIKORA GUTE?*

**<u>Amoko y’Ibikoresho Bikoreshwa Mu Byogajuru</u>**

**Ibikoresho bikoreshwa mu byogajuru** ni ibice by’ikoranabuhanga bishyirwa ku byogajuru (satellites) kugira ngo bifashe mu mirimo itandukanye harimo itumanaho, kugenzura isi, ubushakashatsi mu kirere, imiyoborere y’ubwirinzi n’ibindi. Ibyogajuru ubwabyo bikora nk’icyicaro cyangwa icyuma cy’ikoranabuhanga gishobora kugenda mu isanzure, kikohereza cyangwa kikakira amakuru.

Ibikoresho bikoreshwa kuri ibi byogajuru bigira amoko atandukanye, bitewe n’akazi byagenewe gukora. Uko ikoranabuhanga rigenda ritera imbere, ni ko n’ibi bikoresho bigenda bitera imbere mu bunini, ubushobozi no mu gukoresha ingufu nke.

## 1. Ibyogajuru by’Itumanaho (Communication Satellites)
Ibi ni byo byogajuru bikunze gukoreshwa cyane ku isi. Bifasha mu gutanga serivisi z’itumanaho nka televiziyo, telefoni, internet, n’itumanaho rya gisirikare. Bikoreshwa mu guhuza ibice bitandukanye by’isi hakoreshejwe sinyali za radiyo cyangwa microwave.

**Ibyo bikoresho bikubiyemo:**

* Antena zo kohereza no kwakira sinyali
* Amplifiers zongera imbaraga ya sinyali
* Transponders zohereza sinyali kuri point runaka

**Urugero**:

* *Intelsat*
* *Eutelsat*
* *Starlink* ya SpaceX
* *Inmarsat*

## 2. Ibyogajuru byo Kugenzura Isi (Earth Observation Satellites)
Ibi byogajuru bigamije gutanga amakuru ajyanye n’imiterere y’ubutaka, ibidukikije, n’imihindagurikire y’ikirere. Bikoreshwa mu buhinzi, igenamigambi ry’imijyi, kugenzura ibiza n’ibikorwa by’ubucukuzi.

**Ibikoresho bikubiyemo:**

* Kamera za multispectral na hyperspectral
* Radar (SAR – Synthetic Aperture Radar)
* Sensori za infrared na thermal

**Urugero**:

* *Landsat* (ya NASA n’Ikigo cy’Igihugu gishinzwe ibidukikije – USGS)
* *Sentinel* (Copernicus program y’Ubumwe bw’u Burayi)
* *Terra* na *Aqua* za NASA

## 3. Ibyogajuru bya Gisirikare (Military Satellites)
Ibi ni ibyogajuru bikoreshwa n’ingabo mu rwego rwo kwicungira umutekano, gutahura ibikorwa by’abanzi, cyangwa gutanga amakuru ku bijyanye n’ikirere n’aho ibikoresho bya gisirikare biri. Bimwe bikora akazi k’ubutasi, gufata amajwi n’amashusho, n’ibindi.

**Ibikoresho bikubiyemo:**

* Kamera zifata amashusho meza cyane
* Sensori z’ubushyuhe
* Radar zishobora gutahura ibintu bitagaragara ku maso

**Urugero**:

* *Lacrosse satellites*
* *NROL series* za National Reconnaissance Office (USA)
* *Kosmos* satellites z’u Burusiya

## 4. Ibyogajuru by’Imyidagaduro n’Itumanaho rusange
Ibi byogajuru bitanga serivisi zijyanye n’imyidagaduro, harimo gukwirakwiza amajwi n’amashusho, radio, GPS, n’ibindi. Bikoreshwa n’abantu ku giti cyabo cyangwa ibigo bikora ubucuruzi.

**Ibikoresho bikubiyemo:**

* Transponders z’amashusho n’amajwi
* GPS receivers
* Modulators zifasha kohereza amashusho meza

**Urugero**:

* *DirecTV*
* *Sirius XM Radio*
* *GPS satellites* (ku bufatanye bwa gisirikare n’abasivile)

## 5. Ibyogajuru bito: CubeSats, NanoSats, na MicroSats
Ni ibyogajuru bifite ubunini buto cyane, bikaba bikoreshwa cyane mu bushakashatsi mu mashuri makuru, mu bucuruzi buto, no mu kwiga ikoranabuhanga rishya. Kubera igiciro gito cyo kubitunganya no kubohereza mu isanzure, byatumye bihinduka ibikoresho by’ingenzi mu iterambere ry’itumanaho ryihariye n’ubumenyi.

**Urugero:**

* *Rwanda’s RWASAT-1* (CubeSat yohererejwe mu isanzure mu 2019)
* *Planet Labs Doves* (imikoreshereze y’ubutaka)
* *Mars Cube One* (ya NASA)

----

## 6. Ibyogajuru by’Ubushakashatsi bw’Isanzure (Space Science Satellites)
Bikoreshwa mu bushakashatsi mu by’ikirere n’isanzure, nko kugenzura inyenyeri, inyuguti z’ikirere (galaxies), umwimerere w’umwuka, n’ubushakashatsi ku mibumbe nka Mars cyangwa Venus.

**Urugero:**

* *Hubble Space Telescope*
* *James Webb Space Telescope*
* *Gaia* (ya ESA)

## Umwanzuro
Ibikoresho bikoreshwa mu byogajuru bigira uruhare rukomeye mu buzima bwa buri munsi. Bifasha mu itumanaho, mu kurengera ibidukikije, mu kwita ku buzima bw’abantu, no mu kurinda umutekano w’ibihugu. Iterambere ry’ikoranabuhanga rizakomeza kwagura ubushobozi bw’ibi bikoresho no gutuma byorohera ibihugu n’abantu ku giti cyabo kubikoresha.
