With the release of DJI Mavic Pro, DJI introduced new wireless controlling technology called, “Ocusync” replacing the light bridge technology which was a hardware-based radio system. First Ocsync was known as the next level of light bridge technology, but after some time, it became clear that those things were different.<\/p>\n\n\n\n
Ocusync is a new transmission system DJI introduced, which is more of an SDR (Software Defined Radio) based system on generic off-the-shelf hardware that allows DJI to keep hardware costs down and use more compact packing as software can be updated.<\/strong><\/p>\n\n\n\n
As I mentioned above Ocusync is an SDR (Software Defined Radio) based system rather than a hardware-based radio system as Lightbridge was. All the DJI software can be run on top of Ocusync standard off-the-shelf hardware therefore rather than having a dedicated chipset for their Radio frequency system they were able to buy off-the-shelf chipsets designed to be used in smartphones and tablets and run the dedicated proprietary link on that hardware. <\/p>\n\n\n\n
As I mentioned above DJI Ocusync technology was first introduced to DJI Mavic Pro which was labeled as DJI Ocusync 1.0. <\/p>\n\n\n\n
Ocusync performance was overall much better than anything had before.<\/p>\n\n\n\n
After some time, DJI released another FPV goggles set named FPV Goggles RE (Racing Edition) alongside their Ocusync Air system and it was DJI’s first dedicated FPV system using Ocusync technology. This was not labeled as Ocusync 1.5 but this was a mid-stage between Ocusync 1.0 and 2.0.<\/p>\n\n\n\n
DJI Ocusync 1.5 didn’t have the same resolution as Ocusync 1.0 but it had lower latency. It was optimizing latency over video quality to allow you to get a better latency FPV link. Therefore this didn’t get much traction than FPV wing users.<\/p>\n\n\n\n
In 2018, DJI released the DJI Mavic 2 series, it came with Ocusync technology labeled DJI Ocusync 2.0. It offered so much better range than the DJI Mavic Pro’s Ocusync 1.0. This version of Ocusync 2.0 also was still based on the lead core chipset and the improved software algorithms on the SDR allowed it to get better performance than Ocusync 1.0.<\/p>\n\n\n\n
The transmission range varies up to 6.2 miles (10 km).<\/strong><\/p>\n\n\n\n
Sometimes after that, DJI released the DJI Digital FPV system which also had their Ocusync technology. It had a dramatically low latency (about 50 milliseconds) that FPV system could get down to. This difference was caused by the replacement of the lead core chipset with a custom silicon SoC labeled the p1 this chipset. It does all the encoding, decoding, and everything you need for the link outside of the multiplexer. <\/p>\n\n\n
DJI was doing was prioritizing latency over range on this system for FPV users.<\/strong><\/p>\n\n\n\n
The transmission distance varies up to 6.2 miles (10 km).<\/strong><\/p>\n\n\n\n
After that, DJI released the DJI Air 2 series with Ocusync 2.0 with a new version of this chipset called the S1 instead of the P1 chipset. The major difference between the S1 chipset and the P1 chipset was S1 doesn’t have the onboarding video processing and it has to be handled externally on the drone or remote controller while the P1 chipset handled everything. The first drone to have this S1 chipset was DJI Air 2 and labeled as DJI Ocusync 2.0. A little after that, DJI Mini 2 was released and had Ocusync 2.0 builtin and had the same setup as DJI Air 2. <\/p>\n\n\n
The transmission distance varies up to 6.2 miles (10 km).<\/strong><\/p>\n\n\n\n
The next DJI consumer drone was the DJI Air 2s which had the P1 Ocusync chipset and it was labeled as DJI Ocusync 3.0. The DJI Air 2s remote controller, which is the same DJI Mini 2’s remote controller (RCN1), with the S1 chipset can do Ocusync 2.0 or Ocusync 3.0 by simply switching software depending on which drone it’s paired with.<\/p>\n\n\n\n
Ocusync 3+ is the latest Ocusync update and was featured in DJI Mavic 3. The biggest difference from Ocusync 3 was really the higher frame rate of the live feed and higher bit rate. The interesting thing in this though is that this again is using that p1 chipset like Air 2s.<\/p>\n\n\n\n
DJI Ocusync 3+ offers a higher frame rate of the live feed and a higher bit rate. It can do 15 Mbps and 1080p@60fps on the live feed whereas the Air 2s can only do 1080p@30fps and has a much lower bitrate, even though they are using the same p1 chipset.<\/strong><\/p>\n\n\n\n
