One of many key advantages of WingtraOne GEN II’s VTOL design is that it may well fly with heavier payloads. Particularly, by eradicating the chance of shock and harm by way of stomach touchdown, engineers had been free to pick out increased high quality cameras. They aimed for the perfect outcomes when it comes to flight time, decision and accuracy. Wingtra’s two Sony RGB nadir payload choices—the entry-level a6100 24 MP APS-C, and the higher-resolution RX1R II 42 MP full-frame—reveal these outcomes.
So what’s the distinction between these two payloads, and the way do you select between them given your drone wants proper now? We’ve run take a look at flights and can now share these in addition to key insights that will help you select the best choice.
Sony a6100: good protection, lighter on the information, excessive accuracy and versatile
For a number of causes, the a6100 is taken into account an entry-level possibility. Amongst these are its lower cost tag and lighter knowledge seize load for a given space. These components alone make it a reliable payload to begin working with on a variety of tasks. In truth, flying it at 120 m (394 ft) above floor degree (AGL), your common accuracy will likely be about 2.4 cm (0.9 in), a decision that satisfies functions the place a superb quantity of element is required. Just a few examples embrace: web site planning, mine restoration, oil spill monitoring, landfill tasks, pure catastrophe harm evaluation and extra.*
Moreover, its 20 mm lens supplies a large angle for picture seize that ends in the broadest protection doable at a restricted altitude—240 ha (600 ac) at 120 m AGL. The info is wealthy sufficient to look at key options in an space, but nonetheless light-weight for processing.
*The a6100 is a step ahead when it comes to decision (as much as 24 MP from 20 MP) from Wingtra’s earlier entry-level RGB resolution, the QX1 payload, which has already demonstrated success on mission use circumstances (linked and catalogued by sort and payload on our use case web page).

Sony RX1R II: highest decision and accuracy, and exacting particulars for exact evaluation
Though a bit costlier, the Sony RX1R II is a finest vendor for a number of key causes. You possibly can fly at a GSD all the way down to 0.7 cm (0.3 in), and at a typical mapping peak of 120 m (394 ft) AGL, you may seize at a median GSD of 1.6 cm (0.6 in). The decision distinction is most noticeable when zooming out and in of orthomosaics. You possibly can discover this within the orthomosaic module above. Protection with the full-frame 35 mm lens setup remains to be sturdy at this flight altitude—210 ha (520 ac).
As for what functions it serves finest, it helps to contemplate that the accuracy out there with the RX1R II will make a marked distinction in quantity measurements, since cubed cms/ins add up quick. This will likely be particularly essential when measuring belongings on a mine, earthworks, and customarily evaluating contractor particulars with mapped proof. Past this, any utility benefiting from the flexibility to view advantageous particulars on demand will certainly profit.
An in depth-up view of a building web site presents a glimpse of the decision distinction between the Sony RX1R II and a6100.
At a look: variations between the RX1R II and a6100
| Sony a6100 | Sony RX1R II |
|---|---|
| 20 mm wide-angle lens means bigger protection for flight time at 120 m | 35 mm lens plus full body, means solely barely much less protection than the a6100 at 120m (393 ft) and the best protection and effectivity for this decision* |
| Economical | Greatest vendor, barely increased value |
| Good decision | Exacting decision |
| Much less knowledge | Extra knowledge |
| Functions Photo voltaic area building Landfill tasks Oil spill monitoring Mine restoration | Functions Actual volumes (i.e., mining, contract reconciliation) Nice particulars Street surveys |
*With the RX1R II, you may fly at 180 m (590 ft) AGL to get the identical decision because the a6100 and canopy a bigger space, 330 ha (815 ac) particularly.
So which one must you go for?
Each the a6100 and the RX1R II present main high quality on your photogrammetry wants. Nevertheless, if you’re on a price range and nonetheless ramping up your program to course of huge datasets, beginning out with the a6100 will nonetheless get your jobs finished proper. As you get expert with this payload—when it comes to knowledge seize, processing and analytics—an improve to the RX1R II will deliver you extra subtle outcomes and a extra sturdy foundation for calculations, comparisons and monitoring of advantageous particulars.
