Geoscan and Topcon Team Up for Performance and Accuracy

Geoscan and Topcon Team Up for Performance and Accuracy

The greatest spatial information firm in Russia, Geoscan, integrates Topcon’s ultra-compact B111 GNSS receiver inside its high-performance UAV programs. The firm is now wanting into the potential of bringing Topcon’s Topnet Live correction service to its prospects in Russia and past.

“We are offering the entire know-how stack for aerial surveys and spatial digital twins,” mentioned Kirill Konev, chief enterprise growth officer for Geoscan. “We do sensors, microelectronics and UAV manufacturing. We supply survey companies, and we do autopilot, photogrammetry, visualization and analytics software program.”

Among of the corporate’s high performers are the multi-rotor Geoscan 401 and Geoscan Gemini UAV programs. These programs ship aerial images with high-precision spatial information. Outputs embrace 3D level clouds, digital floor and terrain modeling (DSM, DTM), orthomosaic mapping and 3D textured polygonal modeling of surveyed objects.

“We cowl most aerial survey software fields,” mentioned Konev. “That consists of rural and concrete, roads and energy strains, oil and gasoline, mining, agriculture and ecology, cultural objects and lots of extra. We additionally do industry-best academic merchandise and drone exhibits. At the second, we’re energetic in additional than 140 nations all around the world.”

The Geoscan GNSS receiver of alternative is the Topcon B111. This ultra- compact GNSS board is able to offering scalable positioning from sub-meter DGPS to sub-centimeter RTK positioning. The light-weight B111 affords 226 common channels for dependable, ‘all-in-view’ monitoring of GPS, GLONASS, BeiDou, Galileo, QZSS and SBAS indicators.

The benefits of the Topcon B111 are a number of and various, mentioned Konev: “One of the primary benefits for us was the convenience of set up and set-up. Topcon was additionally the primary firm to supply the OEM boards. In our expertise, in comparison with its rivals, the B111 has extra channels, it’s extra delicate and steady, and it’s extra reasonably priced.”

The B111’s versatile design, together with its low energy consumption, complete communication interfaces and peripheral assist, do make it very simple to combine into any exact positioning software.

Beating Magnetic Anomalies

Geoscan can level to a variety of latest tasks the place the Topcon B111 has supplied essential accuracy for its UAV operations. Take the case of Karelsky Okatysh OJSC, a number one iron ore mining and processing firm in Russia, with operations at 5 open pits, from 55 to 345 meters deep. Karelsky Okatysh carries out a number of kinds of surveys usually, together with tacheometric surveys, floor scanning and aerial images. The firm has used each Geoscan 401 and Geoscan Gemini UAV programs for high-resolution aerial surveying inside their iron ore pits.

A key functionality that units Geoscan multi-rotor programs aside from their rivals is their capability to function underneath anomalous magnetic circumstances. Such circumstances are sometimes noticed in areas the place iron ores and different iron- containing rocks happen.

Most rotor-based UAVs use a magnetic compass sensor for azimuth navigation, which may malfunction underneath electromagnetic interference. Geoscan engineers developed an algorithm that makes it attainable to fly with no magnetic compass, utilizing as an alternative information obtained from the GNSS receiver, on this case the Topcon B111.

Large-scale testing of this progressive answer was carried out at one pit on the Karelsky Okatysh mines throughout the summer season of 2020. Operators surveyed on the pit floor the place small magnetic anomalies had been noticed, contained in the pit at medium depth and on the backside of the pit the place the biggest magnetic anomalies had been noticed. The most measured magnetic discipline worth was nearly 3 times regular background.

The compact Geoscan Gemini with Topcon B111 working rather than the usual magnetic compass sensor supplied the required output high quality in all the checks, delivering a spatial decision of 1.8 cm/pix, aircraft accuracy down to five cm, and peak accuracy all the way down to 10 cm.

World Heritage, and High Altitude

Another challenge that benefited from the Geoscan/Topcon partnership concerned the creation of an entire 3D mannequin of the Citadel of Damascus , carried out underneath the auspices of the Institute of History of Material Culture of the Russian Academy of Sciences.

The Сitadel was photographed in November 2020 utilizing Geoscan 401 and Geoscan Gemini UAV programs, geared up with the Topcon B111 GNSS receiver. Images had been processed and transformed right into a 3D mannequin utilizing Agisoft Metashape software program. The outcomes have been transferred to the Directorate General of Antiquities and Museums of Syria and can serve in assist of restoration works on the location. The 3D mannequin can also be accessible to view on-line.

Geoscan, with Topcon onboard, reached new heights when specialists scaled Mount Elbrus, the best peak in Russia, so as to take a look at Geoscan UAV efficiency underneath powerful highland circumstances. Geoscan Gemini carried out admirably at an altitude of 3800 meters. All UAV inside parts, together with the Topcon B111 board, survived the take a look at. The Geoscan 401 UAV, additionally geared up with the Topcon B111, flew at even increased elevations, taking off from a base station at an altitude of 3850 meters and taking 10 minutes to succeed in Elbrus’ summit at over 5600 meters. During this take a look at, the Geoscan 401 operated efficiently at temperatures all the way down to -10°С.

Assessing Interest in TopNet Live

Konev mentioned Geoscan groups first got here into contact with Topcon on the 2018 InterGeo occasion in Frankfurt, the place they mentioned two matters: “We talked about Topcon branding with Geoscan UAVs, which resulted in our utilizing the phrase ‘powered by Topcon’, with the Topcon emblem, in our Geoscan advertising and marketing materials. And they had been additionally enthusiastic about reselling our Geoscan Gemini. Topcon was positively enthusiastic about investigating this feature and wished to know if they might get a pre-production unit for testing within the Netherlands.”

The outcomes of those early discussions had been constructive and mutually useful, and the 2 sides have since maintained and expanded their relationship. “We are actually in touch with Topcon each week,” mentioned Konev, “primarily discussing the potential of Geoscan reselling Topnet Live to our purchasers in Russia and different nations. We are actually updating our web site with Topnet Live info, and together with Topnet Live in our advanced product proposal, which is able to permit us to estimate the attainable demand for that product.” Konev mentioned Geoscan can also be actively testing Topnet Live in varied survey tasks.

Here to Stay

Meanwhile, Konev mentioned, the outlook for Geoscan is constructive: “The greatest alternative remains to be in aerial logistics, which goes to have a serious influence when there’s a stable enterprise mannequin for operations in cities and their close to neighborhood. However, there are additionally a number of main challenges which might gradual drone implementation, primarily being the growing strictness of laws, but in addition the issue of creating and deploying UTM [unmanned aircraft system traffic management] and D&A [detect and avoid], that are clearly required to construct up the extent of drone implementation.

“We take into consideration the drone {industry} as some of the disruptive, and but it’s prepared for implementation,” Konev mentioned. “The hype curve for drones is flattening out and we’re one of many corporations keen to remain round and consolidate the market. We imagine we will present important price and time reductions in comparison with conventional surveys in most industries.”
