Tommy did a number of tests within the past week with immersion vtx.

In all cases it worked flawlessly.

said it before. ..  it depends on the vtx you use.   

Same could be said with the likes of skyzone.   They work with the irc system. ..  but range will not be as good.   But still quite acceptable.

Hi Jake,

As you might of seen the other day when we were at brinscall it was tracking all of the IRC transmitters you guys were using 100%. However we have found other units tested to be not so good hence we can not recommend 100% compatibility with all IRC at this time.

Thanks

Tommy

good for locating lost planes lol?

Hi Mark,

Thanks for your comments

As for lost model locator it has found my twinstar when the pan and tilt wanted to look at the left motor only  :o so it ended up in a tree at the Kirkham flying fields with Brod and Ady the tracker took me right to it lol so i can safely say it works.

Thanks

Tommy

From a technical point of view I am struggling to see how the IRC transmitter can be significantly different from Boscam or others? All the transmitters send a video carrier and two audio sidebands? I assume that the system listens to the 'noise' on the audio channel and then adjusts the antenna to minimise this?

Is it possible that the Boscam receivers are not as accurate in the frequency as IRC ..this might explain the problem?

Another question how is the video signal connected to the goggles /screen, cable or on 5.8.

Certainly very impressed with video demo ..If you could be 100% on compatibility with IRC then you would have another order!

Th diference is really an issue betwewn manufacturers have different standards.

Airwave vs SkyRF.

Frequency wise. ..   they use the same frequency.   And they can view each others video.   

From my understanding,  the difference affects end range.   If you mix manufacturers,  you dont get to fly as far.  So the question is.. how far do you want to go? 

In our tests we have only had one fatshark vtx out of many that the tracker did not work well with.   The rest where all fine. 

Plemty people on yhe net do mix boscam and irc with no issue.. so far from conclusive.  :)

Oh.. connection is with a cable.

just a niggling Q: what if your out a few miles, and someone puts a quad/plane up between your plane/quad using the same frequency?

What would happen if someone did the same without a tracker?

The risk is there every time we fly.  Regardless of the type of tracker you use.

It is minimised by using highly directional antennas,  but will never be 100% safe.

I guess this is why we have rth systems :)

so would the RSSI Pro Tracker, start to track the other plane/quad? as that would have the strongest signal?

The same as what happens at any meet where someone turns on their kit on the same channel as someone else flying. The person who is flying picks up the closer ground recording and renders any tracker or video system useless until they turn it off.
Education and schoolin is good, but FPV is gooder :)

The other craft would not need to have taken off to render the flying parties video feed useless so where the tracker points until the grounded party turn their kit off is irrelevant.

Correct.  This is an issue with the fact that we use analog video signals with fixed frequency assignments.

Just like it used to be back in the days pre 2.4ghz for for control systems.

How the tracker responds in the event is dependant on how strong the signal is, and where in relation to the tracker / plane the signal source is.

A week signal at 90 degrees to the side will have little impact.   The directionality of the antennas will cancel it out.  A strong signal close in.. well thats a feed wipe out event.

the tracker has a reset button it that instantly stops the tracking.  This is a partial help,   But this will noy help you if your video feed is swamped out by a stronger signal.

Just should say that that that is true for trackers that only use video feed to track but isnt the case for my DIY tracker  which can use both the Video Signal and FrSky RC telemetry to send tracking data back so if video is corrupted it will continue to track and with Frequency Hopping on FrSky its relatively hard to jam. You could also add 433 MHz telemetry ( As far as I know 433 MHz is actually legal as well for telemetry in UK), so you have potentially 3 paths to get telemetry.

The major selling point of the RSSI tracker is that you dont need anything in the plane. However, If your plane has RTH then at that point you will have a GPS on board, a FC  and the means to send telemetry.
