Introduction

UAV Wing­traOne PPK* the world-famous Swiss UAV man­u­fac­tur­er, Wing­tra, has set a new lev­el in the large-scale geo­det­ic and car­to­graph­ic fields of activ­i­ty. Sup­port­ed by indus­try part­ners, pho­togram­me­try soft­ware provider Pix4D and GNSS boards from Septen­trio, the Wing­traOne PPK is capa­ble of trans­mit­ting ortho­mo­saics and 3D mod­els with 1cm pre­ci­sion.

*PPK — Post-Processed Kine­mat­ics — “kine­mat­ics in post pro­cess­ing.”

Wing­tra designs, man­u­fac­tures and mar­kets high-pre­ci­sion VTOL unmanned aer­i­al vehi­cles for data col­lec­tion through aer­i­al pho­tog­ra­phy. Wing­tra entered the glob­al mar­ket in ear­ly 2017 and has since been sold world­wide. The com­pa­ny recent­ly part­nered with RDO Inte­grat­ed Con­trols (a lead­ing sur­vey­ing equip­ment deal­er) to raise an addi­tion­al $5.8M to meet demand in 2018.

“With the lat­est update, the Wing­traOne PPK drone can offer some­thing that has not been seen in drone pho­togram­me­try until now — wide cov­er­age and high res­o­lu­tion of pre­ci­sion accu­ra­cy. For exam­ple, in one hour of flight, Wing­traOne will be able to cov­er 130 hectares, which is 240 foot­ball fields, by pre­sent­ing maps at the out­put with GSD* less than 1cm/pixel with absolute pre­ci­sion down to 1cm,” explained Wing­tra’s CTO Armin Ambühl.

*In Eng­lish lit­er­a­ture GSD — ground sam­ple dis­tance or “pix­el size on the ground”

These results are new to the indus­try — until now, no exist­ing pro­fes­sion­al UAV could offer such accu­ra­cy. Pre­vi­ous­ly, the world of car­tog­ra­phy was dom­i­nat­ed by only two types of drones: fixed wings and mul­ti-engine or mul­ti-rotor air­craft. Fixed wing drones can cov­er large areas but can­not trans­mit high­ly accu­rate data. Mul­ti-rotors can pro­vide pre­ci­sion accu­ra­cy, but they can only cov­er small areas.

“The VTOL (ver­ti­cal take­off and land­ing) fixed wing drone com­bined the two types of drones, result­ing in improved con­trol qual­i­ty and extend­ed flight times,” added Armin Ambühl.

PPK

RTK (real-time kine­mat­ics) or PPK (post-processed kine­mat­ics). RTK requires a real-time con­nec­tion to the base sta­tion and cor­rects the GPS sig­nals dur­ing the flight, while PPK cor­rects them after the flight and there­fore pro­vides more reli­a­bil­i­ty and con­sis­ten­cy. In addi­tion, PPK does not depend on base sta­tions or base sta­tion net­works, and has high reli­a­bil­i­ty, accu­ra­cy, con­ve­nience and time sav­ing. To obtain accu­rate aer­i­al pho­tographs up to 1 cm, spe­cial flight prepa­ra­tion and inten­sive post-pro­cess­ing steps are not required.

PPK (Post-Processed Kine­mat­ics) tech­nol­o­gy allows Wing­traOne to reach a new lev­el of accu­ra­cy. PPK cal­cu­lates high­ly accu­rate geolo­ca­tions for each image by com­bin­ing GNSS data with cor­rec­tion data from the near­est ref­er­ence receiv­er.

Pix4D

After aer­i­al data col­lec­tion, Pix4D post-pro­cess­ing soft­ware works as a pow­er­ful tool for cre­at­ing orthopho­tos and 3D mod­els from geo­t­agged images. Armin Ambühl notes that “after pro­cess­ing the data, the results become visu­al — ortho­mo­sa­ic and 3D mod­els are impres­sive­ly detailed and allow for accu­rate cal­cu­la­tions”

load capacity

The high pay­load capac­i­ty of Wing­traOne allows the inte­gra­tion of the high­est lev­el pay­load on board the drone: the Sony RX1RII and the mod­ern Septen­trio PPK sys­tem. “An RMS error of 1.3cm hor­i­zon­tal­ly and 2.3cm ver­ti­cal­ly with­out any ground con­trol points is a sig­nif­i­cant leap for­ward in effi­cient aer­i­al pho­tog­ra­phy, sav­ing time spent in the field,” says Ambühl. “We are thrilled to offer such a high res­o­lu­tion, high accu­ra­cy Wing­traOne sys­tem to the demand­ing sur­vey­ing indus­try.”

Future

The Wing­tra team expects the Wing­traOne PPK to become the most sought after drone for sur­vey­ing and map­ping appli­ca­tions. Max­i­m­il­ian Boos­feld, Chief Oper­at­ing Offi­cer of Wing­tra, added: “Our unique VTOL tech­nol­o­gy has already proven itself in the field: cadas­tral sur­vey of the largest ura­ni­um mine in Africa and dig­i­tal mod­el­ing of the Alpine Heights have helped us estab­lish a sol­id mar­ket foot­ing in this area. By com­bin­ing the capa­bil­i­ties of VTOL and PPK, we have gained an advan­tage over exist­ing solu­tions in aer­i­al pho­tog­ra­phy. I believe Wing­traOne will com­plete­ly replace fixed wing drones in large scale map­ping mis­sions in the near future as we have just set a new indus­try stan­dard in drone pho­togram­me­try.”
