SparkFun RTK Torch - Karamin, Mai Binciken Ruwa tare da Ayyukan RTK

Sparkfun RTK Torch, mai binciken GNSS

El SparkFun RTK Torch m, mai karɓar GNSS mai hana ruwa wanda ke ba da ayyukan RTK don ma'auni mai tsayi. Duk da girmansa mai ɗaukar nauyi, RTK Torch yana cike da fasaha na ci gaba. Yana da tsarin ESP32-WROOM wanda ke ba da Wi-Fi da Bluetooth, da kuma tsarin Unicore UM980 mai jituwa na RTK wanda ke karɓar siginar GNSS mai yawan mitoci tare da babban daidaito. Hakanan ya haɗa da STM32WLE5CCU6 microcontroller daga STMicroelectronics don samun gyare-gyare ta rediyon LoRa.

RTK Torch shine juyin halitta na RTK Facet na baya, amma tare da ingantaccen haɓaka. Yana bayar da faffadan liyafar, mafi girman daidaito da tsari mai ɗaukar hoto. Kamar Facet, RTK Torch ya zo tare da akwati, 3m USB C zuwa C caji na USB, 65W PD adaftar bango, da adaftar eriya 1/4 ″ zuwa 5/8 ″.

Har ila yau, ya dace da buƙatu daban-daban godiya ga nau'ikan aikinsa daban-daban:

  • Matsayin GNSS (daidaicin ~ 800 mm).
  • Matsayin GNSS tare da RTK (daidaicin 8mm), ta amfani da tashar tushe na gida.
  • Matsayin GNSS tare da PPP-RTK (daidaicin 14 zuwa 60 mm), ta amfani da gyare-gyaren PointPerfect.
  • Matsayin GNSS tare da ramuwa karkatarwa.
  • GNSS tashar tashar.
  • GNSS tushe tashar NTRIP uwar garken.

Wannan na'urar ta dace da ayyukan da ake buƙata Madaidaicin yanayin ƙasa da taswirar GIS (Tsarin bayanan yanki). Ana iya amfani da shi a aikace-aikace irin su safiyo, noma da gine-gine kamar binciken.

Ko da yake RTK Torch yana da gidaje Dust and water resistant (IP67 rating), Ba a ba da shawarar yin hawan waje na dindindin ba. Tabbas, na'urar tana gudanar da SparkFun's RTK Ko'ina firmware na duniya, wanda shine tushen buɗewa kuma an shirya shi akan GitHub. Hakanan ya haɗa da Zero-Touch RTK, fasalin da ke ba da damar yin gyare-gyare ta atomatik ta amfani da takaddun shaidar hanyar sadarwar Wi-Fi (akwai a cikin zaɓin yankuna kuma tare da biyan kuɗi na farko kyauta).

Hakanan zaka iya saita wayarka zuwa karbi bayanan NMEA daga Torch RTK ta Bluetooth. Na'urar tana aiki tare da aikace-aikacen GIS da yawa don Android da iOS, kamar Taswirar SW (shawarar), Survey Master Vespucci, QGIS da QField (waɗannan uku na ƙarshe buɗaɗɗe ne).
