    All you need to get highest accuracy is to offset static and dynamic GPS error.

    To offset static error you need to approach, vertified, geolocated groundstation

    To offset dynamic, ionospheric error (live maps are available for Australia), you need to receive ionospheric error via 3G/4G

    But if none of the above are available, you can still triangulate geolocation, receiving geolocation offset from 2-3 other GPS enabled smartphones, operated nearby, reading offset from static GPS enabled smartphone/s, received by mobile GPS (installed on the drone), since ionospheric error should effect all GPS devices nearby alike.

  • @ d j, you said a $50 smartphone as an RTK GPS? Can you make that please to verify your statement is correct?

  • All you need to build 10cm accuracy RTK-like GPS is $50 smartphone and correction data received via 3G/4G/LTE on free/ non-free basis

  • Hi Harish, 

    Oscar is integrated with our own RTK boards, which is compatible with various flight controller including Pixhawk. 

    If you use for UAV, we recommend you choose our OEM boards kit for UAV, it is more small and light. Please check link as below, https://www.tersus-gnss.com/product/gnss-kits
