Hello, everyone! It’s really nice to see you guys here. This is Keven/Anthony from South/Surveytech, and I am very happy to have some new information for our dear GEP friends. It’s A Story of UAV, let’s see how UAV helps us to do more with less, ok?
Well, here we go! These are the topics that we are going to cover today and I am sure all such contents are very good for your reference.
First of all, I would like to show you, why UAVs are so hot nowadays?
When you input UAV and search it in Google, there are so many web links that you may look into details. As UAV appears so frequently in our daily life, I don’t think I need to explain what it is. Right, unmanned aerial vehicle has already been known to us for quite some time.
As the rapidly evolving technologies of UAV are being exploded nowadays, this stuff have attracted lots of attention from the world stage. See, there are more than 40 events around the world this year, and most of the expos are held in USA, Europe and China, where drones are already so popular for commercial applications.
At the beginning, I would like categorize the UAVs into 2 groups. It was firstly used for military purposes 100 years ago and in recent decades, civilian-use UAV came up commercial applications.
As military-use UAVs are too far away from us, we just focus on civilian-use ones. They fall into 2 groups as well, consumer-grade and professional-grade. Namely, you may understand very easily that consumer-grade UAVs are made for everyone to enjoy UAV flight or pilot dream. However, professional-grade UAVs are particularly produced for industrial applications that bring us profit. This is a key point!
Let’s find the answers in this comparison table. Professional-grade UAVs can fly beyond line of sight. Because the flight control software at ground control station keeps communicating with it even out of visibility. And it can fly more than half an hour and even up to several hours, as sometimes we need a number of aerial images then it’s better to keep it flying longer in the sky. And for sure, with a stronger body, it takes out unwanted vibration against the wind. And it can carry much more and is equipped with high standard camera. Consumer-grade UAV uses mini integrated camera or small digital camera can not bring out high quality maps. Maybe just a few of you noticed this and were surprised, why camera needs to be calibrated. Come on, man! The camera equipped on the UAV is just like an imagery sensor, or say, lens for this measuring tool. Don’t you think optical instruments require regular calibration once in a while? So why did you bring your ET, auto level or total station to service workshop for calibration every 2-3 months? … so finally, it should be priced higher than consumer-grade.
Frankly, times have changed and we have to change our mind as well. Living in the ever-changing world, we need to keep updated with the ever-changing measuring tools, right? It’s always good to know, no matter you use it or not, am I right? Long long ago, our ancestors used EDM. And almost 30 years ago, total station was born. Then in 1990s, GPS RTK became our new partner to replace part of job of total station. After some time, CORS came up with constantly established infrastructure for fixed base station use. And now, we have we have a new friend, UAV. I guess some of you would be touched by such changes and in all those years, South kept telling you GEPs such marketing stories, like A Story of total station, A Story of RTK,,, and we today we come to A Story of UAV.
Ok, then let’s see how UAVs benefit surveying?
Usually, when we talk about UAV, the first brand and first product that occur to our mind would be DJI and Phantom series. It’s popular around the world due to its high cost performance and affordability, so it covers more than 70% of the consumer-grade UAV market in the global stage. Yes, DJI did a pretty good job and they stimulated the industrial supply chain of UAV productions in China. But unfortunately, DJI products just belong to consumer-grade because the camera it uses could not be calibrated, or else, some high-end DJI copters can just last 20 minutes. So, check our recommendations, please.

So, how should users do with SkySolutions?
As we know. CORS become more and more popular in the world, lots of countries and religions apply it into survey work to replace traditional survey way. So what is CORS? CORS can be defined as one permanently fixed Base to provide differential correction through internet, which is integrated with ......
The traditional 1+1 modes of RTK receivers (one base and one rover) has many inconvenience.
Then let's see the classification of CORS. CORS Can be divided into three types according to cover area and application type. Please see the table, single Base , Multiple Base and network CORS, their detailed datasheets are included in the table.
Let's see the next slide. Software can monitor user location and record trajectory real-time.
CORS is not a integrated product, the antenna is separated with receiver, let's see its antenna. What we provide is Choke ring antenna called CR3-UHG.
