I use an EVO 2 pro v1 for mapping (with a Topodrone dual freq gps) and I can tell you that although the EVO is a wonderful drone for mapping (camera is awesome), its ability to fly against a headwind is dismal. I have almost lost my drone a few times when mapping big areas when getting a little...

This is an insane quirk that has driven me mad for a year and half. I use my EVO 2 Pro for mapping and I figure I lose about 5+ minutes of flight time for each flight as the drone twirls in place at the end of each flight line. I have given up that Autel will ever address this issue.

I want to know how PPK is implemented. What this means is that when a mission starts the drone will be set in a mode that collects raw gps data in a kinematic mode, that is collected to a file. What gps coordinates are embedded to the EXIF data when a photo is taken is of no importance. What is...

Hello, given that the EVO 2 RTK seems to be a mystery bird (NO documentation), I was wondering if someone could give me some information on how PPK is implemented? 1. Are shutter time-marks embedded in a RINEX file? 2. Can one select which satellites to use and the collection rate (Hz)? 3. Any...

Nice! How would one get information on the details of this? For example, can I configure what sats I want to collect? What are the different collection rates (Hz)? Can I do a multi-battery mapping mission and if so how do I regain lock? How is the raw data collected? Does the software export...

I'm wondering if Autel has or is going to add PPK support to the RTK platform? Having the ability to go PPK if RTK goes on the fritz is always nice (assuming one has a simple dual freq base station available). In my work I generally avoid RTK and go PPK for the simplicity and reliability.

Autel app and waypoints? Your funny! The amount of time I loose in the air with my drone stopping at every waypoint, in a mapping mission, continues to drive me mad. I have given up on Autel ever finding a solution to this. I think many others have also given up on Autel ever offering smooth...

I use my EVO II Pro for large mapping missions that sometimes require 4 or more flights. So I have 4 batteries. My rule of thumb is that I always try to have my bird back on the ground at 15-20% and I NEVER field recharge them until they cool, which takes 1-2 hours. When I recharge in the field...

I've used a simple 3d printed extender for over a year. Works fine. Simple solution is sometimes the best. You can find the stl file on Thingiverse.

Yup, software is just bad. It is weird because the EVO II is actually a very good drone mechanically, but I'm guessing software is outsourced and not in-house. My first commercial drone was the original 3dr Robotics Solo. Amazing how good that software was for it's time. Too bad the Chinese took...

Does anyone know whether the RTK / PPK gps is single or dual frequency? Hoping it is dual frequency (ZED F9P??) as that makes initialization (obtaining lock) before flight much faster than single. Cool. If you can keep poking Autel to get PPK support functional that would be great. For PPK they...

If they can get PPK working I buy one. For standard PPK the Rinex file will have logged all raw data (psuedo ranges) at whatever interval the GPS was set to collect at - typically 10 times a second (e.g. 10 Hz). Within the Rinex file there should be time stamps. These time stamps are very...

If the drone is working with ntrip then that means it has it has some type dgps going. I bet it is a Ublox gps. If so it is easy peasy to configure it to record raw gps data. What I find strange is that they could have released this drone PPK ready and say that it's RTK options will be coming in...

I've sent various messages to Autel and some other outfits about this RTK drone, but I am not getting any responses. Typical. What I find encouraging is that this RTK EVO 2 seems to be recording "something" to the SD card. Hopefully it is the raw gps data. If the gps being used is UBlox then...

How about just setting up your base as standalone (use an approximate position and no connection to any network) and see if you can get a good solution with your drone sitting on the ground? I would think that there should be some indication as to whether your RTK corrections are float or fixed...
