CHAMP (satellite)

Ihe ịma aka Minisatellite Payload (CHAMP) bụ satellite German nkè e wepụtara n'ubochi irí na ise n'onwa Julaị afọ 2000 site na Plesetsk, Russia ma jiri ya mee ihe màkà nyocha ikuku na ionospheric, ya na ngwa ndị ọzọ nke geoscientific, dị ka GPS radio occultation, mkpebi nke ike ndọda, na ịmụ banyéré ala magnetik nke ụwa.

Ọ bụ GeoForschungsZentrum (GFZ) Potsdam na-elekọta CHAMP.

Ụgbọ mbara igwe bụ ngwa izizi nke ikpo okwu "Flexbus" nke Astrium; GRACE bụ nké abụọ.  Ụdị a gbanwere nke ukwuu na-efe efe dị ka ọrụ GOCE.

 Ngwá ọrụ ụgbọ mbara igwe 
Otu onboard BlackJack Global Positioning System (GPS) Flight Receiver, nke JPL nyèrè, na-enyere aka iji satellite na-esote satellite màkà ọnọdụ ụgbọ ala.  Iji wepụ mmetụta nke ike mpụga, nke na-abụghị ike ndọda (dịka, ịdọrọ ikuku, nrụgide radieshon anyanwụ) satellite nwere ihe dị n'ime 3-axis STAR accelerometer.  A na-eme ka nkwenye onwé onyé nke ọnọdụ orbital site na passive Laser Retro Reflector (LRR), nke na-enyekwa ohere ịhazi ọnọdụ isi site na laser ranging.  A na-atụle àgwà ụgbọ mbara igwe site na iji Advanced Stellar Compass (ASC) nke Mahadum Nkà na ụzụ nke Denmark nyere.

N'ịbụ nkè a kwụnyere na boom, satellite ahụ nwèrè Magnetometer Instrument Assembly System (MIAS) maka ịtụle ala magnetik.  Ụgbọala ahụ nwèrè ike ịlele oghere eletrik nke ụwa n'akụkụ oghere magnetik na Digital Ion Drift Meter (DIDM).

 Njedebe nke ozi 
CHAMP rụzuru ọrụ ya wee banyeghachi na ikuku ụwa n'ubochi irí na itoolu n'ọnwa Septemba afọ 2010 mgbè afọ 10 gasịrị (ndụ imepụta: afọ ise).

Ndị ọkà mmụta sayensị metụtara ya kpebiri na ọrụ ahụ na-aga nke ọma, ọkachasị dịka afọ ise mbụ nke imepụta ndụ gbatịrị nke ukwuu.
