When DJI released the Mavic Pro they decided to change the
transmission system that communicates between the remote control and the drone. The new system is called OcuSync and it has some impressive
capabilities worth looking at.
OcuSync Specs:
Let's go a little deeper and have a look at what the specs
are of the Ocusync system.
Video Resolution
Ocusync can transmit video at either 720p or 1080p. It depends on the situation, but in general OcuSync will use
1080p for close range transmission and 720p for long-range transmission. Which
makes sense, as it is harder to transmit so much data at longer distances.
Video Download Speed
When things are running well, at a shorter distance and low
interference, you can get photo and video downloads at 40Mb/s.
Transmission Modes
THE DJI Mavic Pro using OcuSync starts by scanning for any
local interference and then makes a decision between three transmission
channels: 20MHz mode, the 10MHz mode, and the lowest priority 1.4MHz mode. During flight it will then automatically switch between
channels (within the chosen mode) if it notices any interference. So, the system is very robust.
Latency
A big issue with any transmission system is the latency.
Which is the amount of delay you experience. The DJI team have done a great job with the new OcuSync and
achieved these values:
5ms for remote controller transmission commands
10ms for video data
130ms for videos
Note: 160ms-170ms from the Mavic’s camera to your device
screen under ideal conditions.
Transmission Distance
OcuSync has a great transmission distance and I have seen a
lot of videos on Youtube where people have flown these distances.
OcuSync has a range of up to 4.3 miles (7 km).
