QuestUAV Survey Drone South Korea

AN INDESTRUCTIBLE QUESTUAV “SURVEYOR” THAT FLIES WEEKLY MISSIONS THROUGHOUT SOUTH KOREA AND ASIA

After 3,000 kilometers and 200 hours in the sky, Q-200 Surveyor “Mango Six” is still far away from retirement


 

MANGO SIX - AN AMAZING DRONE

Mango Six is a Flagship of the QuestUAV fleet and commercial drone world. It continues to perform faultlessly, under highly demanding survey conditions with its commercial owner in South Korea, in different countries, different weather conditions, managing rough environments and whatever life throws at it day after day. It goes on and on. So what makes the difference that creates another legend like Mango Six? Is it luck? Or Divine Intervention? Or are there other factors involved? Read on to discover some of its history and the reasons behind its success.


 

CHAPTER 1 – SOUTH KOREA WANTED A WORLD CLASS LEADER


 

A two year search by the major government-based South Korean land survey department to find a suitable fixed wing drone for their survey needs resulted in an invitation to UAV suppliers from all over the world. Their request was simple: Be the best and the most accurate at surveying a large test site in the heart of Korea, where engineers had prepared millimetre accuracy targets. The submitted result had to be a computer based map of similar accuracy but in a jaw dropping size - covering over 1 square kilometre. Inaccuracies of any note would not be costly to entrants.

The agency, LX, Korea Land and Geospacial InformatiX Corporation, (similar to Ordnance Survey in UK) wanted to find out how accurate each competitor was and how usable design was in order to roll out to each of its twenty six regions in South Korea. The QuestUAV partner in South Korea, HOJUNG Solutions Co. Ltd, were keen to display the capabilities of the QuestUAV 2m wingspan drone, with its gimballed camera.

Though QuestUAV were last to present from the global lineup of competitors, it soon became evident that QuestUAV held the winning design and what was then to become MANGO SIX was ordered. Training was conducted both in UK and in South Korea for a series of complex surveys.

Details of the performance demonstration for LX are here.

CHAPTER 2 – TRAINING, CREW AND MANGO SHAKES


 

After passing LX’s accuracy test, the QuestUAV trainer team spend two weeks in South Korea to prepare the new flight crew of Hojung Solutions for their upcoming surveys. The team, led by Munseok Lee (second from right) received special training on mobile operations and corridor surveys.

After long hard training days, QuestUAV trainer Nigel and the crew rewarded the daily progress in the famous coffee bar - Mango Six. Mango Six became the team's relaxing oasis, briefing room and training headquarters in one. Ten mango shakes later, the crew decided to title their Q-200 Surveyor “Mango Six”. Who would have thought at that time that Mango Six would become one of the most famous UAVs in Asia?

Nowadays, the highly motivated team of Hojung Solutions consists of 3 pilots and 2 commanders accepting the most challenging survey requests.

CHAPTER 3 – 300 KM ROAD CORRIDOR


 

As a result of the great performance during at the flight demonstration, QuestUAV and Hojung Solutions were awarded a contract for a 300 km road and corridor survey for LX. The project had already been given to an Australian contractor, but when it became apparent that Hojung/QuestUAV partnership could do a much better job with a Q-200 Surveyor, the contract was reassigned.

The survey was conducted in the Jeollabuk-do province, in the southwest of South Korea, in October 2015. The 300 km road corridor, including routes in mountains and through tunnels, was flown with Mango Six, equipped with a Sony A6000 camera, over a period of one month. While Mango Six was taking high-resolution imagery from 400ft, the flight crew followed the route on the roads being surveyed in their vehicles. In order to also cover the road-sides, Mango Six flew a few extra lags for a combined mission length of 1,280 km. One intended purpose of the collected data is to allow government departments to determine illegal land use along road-sides.


 

CHAPTER 4 – UAV STANDARD VERIFICATION

South Korean authorities are very strict in their UAV verification standards - much higher than the European CE standards. On average, it takes six months for equipment to pass the equivalent verification in South Korea. Once verified, products can be released for general use.

LX clearly required verification, and to the credit of Munseok Lee and QuestUAV collaboration, Hojung managed to pass South Korean verification in a record breaking one week. Prior certification to operate QuestUAV models in UK, Europe, America, Canada, and Australia helped speed up the process.

Since verification, the South Korean authorities were so impressed by our technology and safety standards that QuestUAV is now the reference standard for fixed wing drones in the country.


 

CHAPTER 5 – OUR RÉSUMÉ AFTER ONE YEAR


 

From maiden flight up until today, Mango Six has spent more than 200 hours in the sky and covered a distance of 2,929
kilometers.

The Q-200 Surveyor has been used for a vast variety of applications, ranging from cadastral surveys, to inspection missions, to archaeological site mapping through to flying over festivals (Muan-gun Lotus festival) and stadiums (Yeongam-gun F1 Formula Stadium).

The teams at Hojung Solutions are now busier than ever, currently conducting a large survey mission with a Q-100 DATAhawk in Tanzania. Mango Six, in the meantime, is joined by three other Q-200 Surveyor drones and two Q-100 DATAhawks, all producing great results for the clients of Hojung So.

CONCLUSIONS

So what do we think has elevated MANGO SIX into its Flagship category? There are a number of reasons, but the most important are:

DESIGN.

Mango Six is a standard QuestUAV Q-200 Surveyor that has been proven to be efficient, rugged and reliable on all continents of the world. Its design has been improved through thousands of tuning elements to become an incredibly efficient and capable survey tool.

TRAINING.

The team had proper training, with two distinct phases spread over three months. They learned to use the aircraft properly and with correct procedures in the first weeks, then moved on to advanced training with a QuestUAV instructor only after those basic skills had been proven.
