Hello,
We'reTHIRDEYE ROBOTICS Team.
Today, as the first start, we will prepare the equipment to be used for aerial surveying and introduce the composition principle.
We will introduce a method of extracting cheap but high-quality data that can be used for air surveying by applying fixhawk to THIRDEYE JI-HOV2 (4+1) and introduce the process of applying equipment along with VTOL aircraft through posts.
Please show a lot of interest and support.
Since 2018, our team has used various equipment to verify performance to obtain high-precision aviation data, and we have found the method that is most used for high-quality aerial surveying worldwide.
It is a PPK-based post-processing drone mapping.
Due to the nature of the fixed wing, the real-time connection between the RTK-based base and the Rover is difficult to continue due to the limitations of communication equipment. As a result, the quality of the data coordinate values decreases.
The alternative is not the real-time communication between base and rover, but the same-time base RTK and rover RTK equipment store GNSS log data and post-process the two GNSS data based on each backed up data after the flight is completed. Post-processing is a method of reducing the precision error of coordinates based on two GNSS logs.
출처 : EMLID DOC(PPK WORK FLOW)
VTOL or fixed-wing aerial surveying is based on this method to date.
Now, let me introduce how to set up the equipment.
KEYPOINT 1.
We do not connect the RTK GNSS to VTOL (i.e. to PIXHAWK) for accurate aerial measurement. That is, you don't have to make redundant investments.
The method we propose is the concept of configuring the VTOL drone separately from the equipment that acquires aerial survey data.
VTOL's incoming GPS uses the basic GPS to select and utilize the device system at a reasonable price.
In other words, drones only need to complete a stable setting to fly on a planned Waypoint basis.
When planning a mission, overlapping pictures are important. This part will be conveyed through an introduction to the future mission plan.
Because of the nature of the flight, the fixed wing is very stable to fly in a straight line (refer to the problem in extreme conditions with high gusts in many directions)
Therefore, if you set the Waypoint and overlap well, you can fly stably on the desired flight path, and if you follow the instructions to get the data from the camera well
The VTOL setting is over.
KEYPOINT 2.
During the VTOL Waypoint mission, equipment that stores RTK GNSS coordinate values without latency (delay) should be utilized when giving commands from the camera.
The equipment we are going to introduce here is EMLID Mapping KIT.

China's drone FC and RTK GNSS manufacturers have no understanding of shutter-ring latency arising from drone mapping. (Recently developed solutions for the CUAV family)
In the shutter ring, if there is a delay in the picture and coordinate in the sink, that is, there is an error in the coordinate value.
To reduce this, EMLID Mapping KIT supports RTK Rover equipment with a camera-connected hot shoe.

The principle of reducing the latency of Hotshoe is as follows.
출처 : EMLID DOC
The camera's hotshoe is designed to work with the same pairing with the camera's shutter.
Based on this, if you give the camera's command from the drone, the camera's shutter works.
In EMLID products, coordinate log data is stored by passing the same command from Hotshoe to EMLID products at the same time that the camera's shutter operates.
his method acquires the optimal survey coordinate value for the aerial survey.
EMLID MAPPING KIT consists of REACH M2 and REACH RS2+ products.
출처 : EMLID DOC
The REACH RS2+ product is used for ground surveying, which is inexpensive, but has performance similar to that of other survey base equipment, making it extremely reasonable to approach.
Also, I think it is very easy to use because the related software is well organized and the documents are well organized in the studio that controls and processes through the app.
So the composition that we recommend is
THIRDEYE JI-HO V2 KIT, JI-HO V2 기자제, FC는 CUAV V5 NANO+NEO3 GPS, EMLID MAPPING KIT
RADIO MASTER JORRO (KC certified), SIYI HM30, SONY A7R4 (many used items) + Samyang 24mm single lens, Air Speed sensor, RC Shutter (MICRO USB), Batteries and Chargers, Laptop
If you prepare the equipment like this, the equipment is ready.
The press systems we recommended are accessible between $11,000 and $20,000 in terms of money.
WINGTRA GEN2 RGB61 and Quantum System Trinity F90+ products, I think you can approach them very reasonably.
The products we recommend are not required, and you can use replaceable products.
This is the end of "PPK aerial survey using VTOL (Pixhawk-based) is not difficult [1. Equipment preparation].
We'll be back soon with production-related content.
Also, please note that we will share the setting value for FC as well as the production of airframe.
This has been Third Eye Robotics.
Thank you.
