    I used a Matrice 400 to act as an aerial relay to fly my Matrice 4T extremely low and far !! You won't believe what an aerial relay is capable of.

    Great information!! We have a dedicated drone training day coming up. We will test the relay function with a 4E and 4T.

    I used a Matrice 400 to act as an aerial relay to fly my Matrice 4T extremely low and far !! You won't believe what an aerial relay is capable of.

    For a waiver, there is none. This would be an FCC issue, not FAA. The FCC did not explicitly ban the DJI 4G dongles, DJI just did not introduce them to the US, most likely due to the controversy that DJI has at this time. You used to be able to add the DJI Dongle to the controller for the M30...

    First flights with the AVSS PRS system making a Matrice 4E a Category 2 sUAS.

    I finally received my AVSS PRS (Parachute Recovery System). This PRS makes a Matrice 4 series drone a Category 2 sUAS allowing for legal flights over people and moving vehicles. It does have a Category 2 maximum wind and also a minimum height you must fly. The most important item is that in...

    I used a Matrice 400 to act as an aerial relay to fly my Matrice 4T extremely low and far !! You won't believe what an aerial relay is capable of.

    Thank you for the feedback! This could be a huge improvement for situational awareness for many industries. In Public Safety, the newest COAs that allow for BVLOS could definitely use this to their own advantage and enhance safety. I am very unfamiliar with using this relay function though. I...

    Matrice 4T: thermal sensor sensitivity...

    It seems like it is turned on, but go into the setting and make sure. On a Mavic 2 Enterprise Advanced the sun damaged the shutter on the camera since this older model does not have Sun Burn protection.

    Matrice 4T: thermal sensor sensitivity...

    You can turn on the Sun Burn Protection. It is located in the Camera Options, accessed from the far right side. With this on, the thermal sensor will keep the shutter closed when it senses a strong infrared source such as the sun. On our Matrice 300 RTK, it closes on propane fires at times with...

    The new L3 will work with the M300, M350 and M400!

    The new L3 will work with the Matrice 300 RTK, 350 and 400 series! It is DJI's first long range LiDAR system and also sports two 100 MP Micro 4/3 RGB cameras. You will be able to gather both colorized LiDAR data and create ortho maps with photogrammetry! Pricing was around $18,000 which is...

    Variable contrast of thermal image

    Great advice above. You can also try the white hot with red tint color palette to highlight the highest temperatures in red. Unfortunately, if the birds are the same temperature as other items in your field of view, you will have a harder time picking them out. We run into this same problem in...

    Matrice 4E - camera settings in mission for photogrammetry

    My preference is 20 mph maximum for any height. Again, your results may vary.

    Map Flown...."Report" - Choose C1 or C2 (Review Now)

    This thread and your answer were perfectly timed. I had just asked this question to myself on how to view the after route report at a later time. Thank you!

    Matrice 4E - camera settings in mission for photogrammetry

    It sets the focus to manual by itself on a photogrammetry mission. When it gets to the start point, watch it. It will look down at the ground, auto focus and then switch to manual infinity. I have found better accuracy at checkpoints with a maximum of 20mph, but your results could be different...

    Change photo storage to SD card or find better way to get photos/videos off the drone.

    I just take out the SD card, place it in an adapter and put into my PC. You can also use a high quality, data capable USB A to USB C, with the C to the drone and the A to a PC. Make sure the drone is turned on.

    Terrain following

    I am not sure of the speed when using terrain following, but I would only use a high resolution DEM. The DEMs from DJI are of lower resolution and dated, at least that's what's been reported from some users.

    M4T Incorrect altitude in photo properties

    Terrain data is a downloaded DEM (Digital Elevation Model) to allow you to use Terrain Following when mapping. The DEM's from DJI can be old and of low resolution. This has nothing to do with images reporting in ellipsoid for altitude. The drone uses either the barometer, VPS or GNSS module for...
