Option to Auto record video on take off with a 1 s "before" buffer.
Same camera sensor as
P4P. Perhaps w/o the mechanical shutter.
Record video from obstacle sensors (1 camera of each pair) when obstacle detected. 480i at 20 fps would be enough.
Fix gimbal level issue (Phantom too). This should be retro fittable s/w.
Integrated ND filters. (0, 2, 4, 6 stops).
Or at least a better means to mount filters.
Round arms.
Rear camera obstacle sensors.
Side sensors (maybe)
Top side ultrasonic sensors.
Power bird by cable during f/w updates or other ground maintenance tasks.
Better GPS receiver
- For a drone in flight in uncluttered conditions, there is no reason at all for a GPS to lose track other than a very intense solar event or deliberate (illegal or military) jamming. The current GPS' are for mobile applications (phones and so on) and are over-sensitive. This results in the GPS jamming on all sorts of spurious interference.
- Or DJI just have poor communication integration with the GPS and that needs to be fixed.
Better navigation system integration.
- Use the baro to x-check the ultrasonic
- Use GPS as alternate heading source (needs movement to determine track) when the compasses are wonky or failing.
- Use same to attempt in flight calibration of the compass if needed
- Use IMU as short term INS positioning system when GPS loses lock (this would be effective for about 1-2 minutes with these cheap IMU's but could prevent fly-aways in strong wind conditions). Automatically enter RTH for this mode and maintain IMU heading after the INS mode times out (2 minutes). This could get the bird back into visual range for an ATTI mode landing or dedreckon pretty close to the home point. Needs wind-speed estimator (before the GPS fails) to improve DR track and distance.
- Resets the GPS during this mode.
- Airspeed and wind estimator. For a stock bird there is a power to airspeed correlation. So for a given power setting and ground speed, airspeed and wind are trivially calculated.
- Supports the INS mode too by giving an estimate of wind speed before a GPS failure.
Pre-flight Lat/Long/Height based waypoint mission planning.
Power consumption in Si units. (ie Watts meter) in DJI app.
Heading/Speed hold. (hands off stick).
Accessory attachments near CofG and an integrated cargo hook and release. Move the VPS cameras out onto the arms and the ultrasonics fore and aft.
Proper Red/Green/White navigation lights with a very bright day "strobe".
Inverted flight mode. Could make cloud videos when the weather is interesting. (in the app hit "invert" or "revert") - automatically rolls inverted or upright. Controls are automatically crossed over to make this easy to fly while inverted.
