Sharaxaad

Calaamadda GPS waa mid aad u daciif ah oo ka hooseysa buuqyada asalka ah ee dhulka u dhow. Isticmaalka antennaska aan la isticmaalin ee caadiga ah 3-6dB korodh meelaha furan, heerka guud ee qaabaynta wuxuu gaari karaa ilaa qiyaastii -120dBm. Calaamadda GPS ee rayidka ah waa calaamad kala duwan oo leh inta jeer ee 1575MHz iyo xawaaraha 2.046MHz. Faa'iidada kala-goynta ayaa ah 43dB, Cb/N0 waxaa loo tixgeliyaa 6dB. Inkastoo nooc kasta oo faragalin ah ay waxtar u yeelan karto ilaa ay tahay mid awood sare , waxtarka faragelinta ee qaar ka mid ah qaybaha soo noqnoqoshada waa mid liita sababtoo ah faa'iidada ballaaran ee kala-goysyada. Hababka si fudud loo hirgaliyo, faragelinta buuqyada buuxa waxay leedahay faa'iido, iyadoo heerka qaladka bit uu ka sarreeyo 10% marka la buuxiyo shuruudaha soo socda:

(1) Bandwidth-ka calaamadda faragelinta waa u dhigma ama ka weyn 2.046MHz, oo daboolaya dhammaan band-ka soo noqnoqoshada ee calaamadda GPS. (2) Kadib markii calaamadda faragelinta la helo iyadoo la adeegsanayo antennada GPS, heerka awoodda guud waa inuu ka sarreeyaa -83dBm.

Jidhka farcanka GPS aan ku soo gudbin kartaa dhalinyarada samada, oo ka mid ah waxaad ugu yaraan in la sameyn doontaan qeybta carruurta dhulka. Seexda qeybta wuxuu isku sameyn karaa ku xaalad badbaadiyaha farcanka, tijaabada instaallashinka, iyo xirfadda iyo macluumaadka droneka ee ku jira. Haddii farcanka uu istiqaal shaqo leh ku sameeyo marka ay ugu yimid marka midka si gaar ah ee carbon fiber mesh board ku jiro oo ay uga soo baxdo carruurta, waxay ku yihiin 30-40 dB qeyb. Haddii marka farcanka lagu sameyn doonaa directionality loo baahdeed iyo installation aan sidoo kale ugu sii loogu yeelo, qeybka ayaa loo baabbiyaan. Kuwaas oo aan uga jirto gainka farcanka GPS ee droneka haddii awooda (maxkamadda carruurta) ayaa -40dB, iyo gainka haddii samada ayaa sheegsanaa doorshiidka GPS farcanka, oo ah intaas oo la sameyn doonaa, yaani maxkamadda lacagta ah ayaa ugu yimid -120dBm. Droneka ayaa 100 metertu u daacad oo carruurta ayaa lacagta ah 0. Waxaa laga heli karaa formula free space loss, lacagta transmission ayaa: Pt= Pr+32.45+ 20logd+ 20logf-G= -83+32.45- 20+ 64+ 40= 33.45dBm .

Xisaabtan kor ku xusan waxay ka dhigan tahay in haddii bandwidth-ka faragelinta uu dhexdhexaad yahay, kaliya 2W oo awood ah ayaa loo baahan yahay si loo dilo GPS-ka diyaaradaha aan duuliyaha lahayn ee ku jira masaafo dhan 100 mitir. Haddii antenna faragelinta ay leedahay 6dB korodh, markaas kaliya 0.5W awood ah ayaa loo baahan yahay. Waxaa la ogaaday iyadoo la tijaabinayo in 0.01W awoodda buuqa amplitude modulation (1) nooca diyaaradaha aan duuliyaha lahayn ay si ballaaran u isticmaalaan caag khafiif ah, taasoo keentay in go'doominta antenna GPS ay aad uga yar tahay 40dB.

Heerka guud ee la helay ma gaari karo -120dBm (taasoo u dhow qiimaha ugu fiican ee aragtida ah waxaana badanaa loo arkaa -130dBm injineernimada).
