Recommended configuration: ADS-B receiver, iPad, software?

[[email protected]]

Christmas is coming. Any suggested combinations?

I currently have a ClearNav II (in a tunnel). Will probably be upgrading the transponder to a Trig 22 in the not too distant future.

I am concerned about iPad legibility in sunlight. Is that an issue? Is there another tablet with markedly better visibility in sunlight?

[[email protected]]

I fly with an iPad mini 4. Visibility is sunlight is fine

[[email protected]]

I should clarify why I am not simply going PowerFLARM to the ClearNav...

1. I spend a lot of time with the ClearNav zoomed in, especially while thermalling early in the flight (which is near the airport and higher density power traffic).

2. When thunderstorms pop up, it would be nice to have the ADS-B weather function to help me find the best route home.

3. A portable receiver and iPad would allow me to use the equipment when flying another airplane.

I'm not set on this direction. Just trying to see what the best option would look like if I chose this route.

[Dan Marotta]

I have both an iPad mini 4 and a Nexus 7 Android.Â* The iPad has better
visibility in the sunlight, but the operating system continually ****es
me off with demands to plug it in and lock it so that it can be backed
up.Â* It also quits if it sits in the sun. Between the brighter screen on
the iPad and the friendlier operating system and wealth of applications,
I like the Android much better.

I have a Trig 22 and ADS-B out in my glider and I also have a portable
WAAS GPS which will receive all of the ADS-B in targets, weather, TFRs,
etc.Â* I haven't used that in the glider yet, but it's coming.

You need to think about what display/flight book software you want. That will likely drive decisions. e.g. lots of folks want Foreflight (I do)... that means an iPad.

Remember to plan to add a TN-70 or TN-72 GPS to the Trig TT-22 to get ADS-B Out for full ADS-B traffic services and/or if you need full post 2020 ADS-B Out compliance. And when that ADS-B Out is configured make sure the ADS-B In links are correctly described so you get those TIS-B traffic services (it's easy for folks doing that configuration to miss portable ADS-B receivers).

Thanks Darryl.Â* I only use the iPad with Garmin Pilot in the 180,
nothing else, so I don't care about any of the Apple stuff.Â* It was the

I have an iPad mini 4 and a Stratus for adsb in. Works great and I can easily move it between aircraft. I do not have adsb out, so I miss some of the traffic. If I’m flying low on the ridges, the adsb signal is poor and intermittent so I’m missing traffic anyway......

[Dan Marotta]

I got the XGPS-170d for ADS-B in capability in the glider long before
considering installing ADS-B in the glider and, I think before we
installed it in the Cessna 180.Â* Unfortunately, it won't work with the
iPad (thanks Apple), and the Android version of Garmin Pilot crashes all
the time and doesn't have all the functionality of the Apple version
(thanks Garmin), so I'm stuck with both now.Â* Had I to do it over, I'd
get the stratus and use the iPad in both aircraft.Â* Oh wait...Â* Avare
won't work on the iPad so I'd have to buy ForeFlight to use in both
aircraft (thanks Apple and/or Google and/or Garmin) so I...Â* Oh never
mind.Â* I'm stuck with both now.

Build yourself a Stratux (http://stratux.me/). Works the same as Stratus. A buddy and I have tested both and there is little or no difference. You can buy a Stratux prebuild or build it yourself. Build it yourself, I think I spent about $150(thru Amazon) with every option and assembled it in about 1/2 hour taking my time and double checking everything. The next one would take about 15 minutes. Works!!

I've built 4 of the Stratux devices. I use it with an iPad Mini, but only in an airplane. I have no problem with the screen, but I'm sure that would change with the unshaded glider cockpit.

[RR]

So here is a question (perhaps several). I have a lx-9000 and power flarm, and adsb out as well. With the flarm, I can see 1090es adsb targets. it is my understanding that I am blind to UAT targets. It looks like there was work being done to output Stratux in flarm format that would allow (with some kind of Mux) to add UAT to my LX-9000 display. Does anyone know if this is currently posable? It seems like it would be a nice addition...

You are blind to UAT direct, UAT via ADS-R and TIS-B (transponder only via SSR.. but you can get some warning of those targets via PCAS).

There have been multiple different people playing around with stuff, be careful what you are lookin at, why not provide a link to what you are asking about? e.g. folks outputting FLARM targets on Stratus via GDL90 protocol won't help you one bit getting to a display that needs FLARM serial data (and a FLARM serial mux won't help there).

Today if you want UAT In traffic get a Stratux or any similar dual-link ADS-B receiver and display that on a separate display, like an iPad/iPhone running Foreflight, or another GA oriented portable ADS-B traffic display system. You will also get the benefit of UAT based FIS-B weather and TFR data, if that's of interest to you. There is no way to display FIS-B data on any glider flight computer/traffic display.... for many pilots I suspect that's more compelling reason to get a separate system like Foreflight than the UAT traffic (well I'm being asked about that a little more than UAT traffic).

Future FLARM receivers like the PowerMouse should at least decode ADS-R and TIS-B data over 1090ES link layer and make that available on displays like your LX-9000.

"I have ADS-B Out" is not very helpful to state... remember "ADS-B" is a fluffy marketing term. Do you have 2020 Complaint/SIL=3 1090ES Out? TABS/SIL=1? Something you rolled yourself/SIL=0???

[RR]

What I was looking at was found here, but seems to be abandoned for now. https://github.com/cyoung/stratux/issues/489

It describes outputting the adsb traffic found on the stratux as Power flarm nema strings. If that can pump those into the 9000, then I can get an audio warning of traffic. Also, all traffic can show up in one place. I was considering another display for weather, but that is an occasional need, not persistent. I think I could do that painlessly on my phone over wifi when I wanted to see if I could get around a T-cell.

and yes, my adsb out is 2020 compliant.

Andy Blackburn was in involved in that one (against my better advice/pessimism). He is in that thread you linked to. You could ask him where this is at, and details about USA ADS-B interoperability etc., if he does not pop up here to reply.

But I'd not get too excited. Getting an ADS-B traffic target at all and then having actual FLARM like warning behaviors from it consistent with how FLARM would actually handle that same ADS-B target, let alone a FLARM target, are two different things. And then how do targets get deduplicated? (well OK you start by using a UAT only receiver.. but what about TIS-B over UAT.. Do you just drop them or do you want that instead of PCAS, etc.). Engineering a proper integrated systems is non-trivial.

So back to Foreflight etc... as your real option today (and you'll turn off the traffic audio warnings on that pretty darn quickly if flying near other gliders).

Or since you have 2020 Complaint ADS-B Out (would also work with TABS, but not SIL=0/non-complaint ADS-B Out) then upgrading PowerFLARM to the LXNav PowerMouse (when it's available in the USA) will at least get you visibility of UAT targets via ADS-R. But that will only work within ADS-B ground station coverage. In that case make sure that the ADS-B Out system setup specifies your glider has ADS-B In on 1090ES.... and check that when you pull a FAA ADS-B flight report it shows that correctly configured.

For folks who really want integrated traffic, I suspect the PowerMouse will be a best option. Maybe with a separate display like Foreflight for WX/TFR and to maybe see if there is UAT stuff being missed.

Rick, I have it working with my own version of the code or I should have said I tested it a year ago, but it never became operational in my glider. I have too many other things going on right now to finish it, but maybe if we get more freezing temps I will get it done this winter. I will talk to you at the airport. I just pulled the PowerFlam out of the glider to get it sent for fixing. Less than 2 years and the radio produces only 200 micro Watts/m2 right at the antenna.

[RR]

Thanks. All I was looking for was a single place to look for Traffic. In that stratux is unlikely/unable to pick up power flarm, adding the "hidden" targets to my primary display seemed like the best option. I don't expect flarm like collision estimation, only all targets in one place. As for duplication, I don't know how much of an issue that will be, if the targets are stacked/overlayed, it may not visually matter.

I use it with both FlyQ on an Ipad mini 4 and with Avare on an android tablet and phone. I've also used it on a trial with Foreflight. Works on a lot of apps and platforms.

Time goes fast. I think you played with it a few years ago. The new hardware/software works very well with ForeFlight as an example.

Thanks Darryl.

This thread already captures the high points of the NMEA Stratux project. Here is some additional color commentary:

I launched the project a couple of years ago and got some initial traction, but then had some issues with pinouts and left it for about a year. At that time I started getting queries from other glider pilots who had found the project on GitHub, so four of us (Andrzej Kobus, John Carlyle, Charlie Gillespie and I) went back at it. By then the fork in the Stratux code was dormant and the person who kindly did the initial coding had lost interest. He did one final round of edits and bowed out.

We did end up with code that successfully modified Stratux to output NMEA sentences more or less in line with the Flarm Dataport Spec. I don't know if this mod works with the current version of Stratux so beware. When I say 'more or less' I mean that the collision warnings don't use the Flarm collision algorithms at all, they are simple proximity warnings that (IIRC) go to the higher alarm values as the target gets closer. It also doesn't de-dupe targets so anyone carrying UAT Out and Flarm (probably no one) or 1090ES Out and Flarm (probably a lot over time - something like 40% of US contest pilots in the latest poll either have 1090ES Out or plan to get it in two years) will generate duplicate targets. As Darryl said, the best plan for that would be to use Stratux for UAT only or have a dedicated display for all ADS-B targets.

There are outer issues when you get down to actual implementation. Some people used a K6 MUX to combine Stratux NMEA with Flarm NMEA so it can be routed to a single display, which seemed to work. The problem with that is that the Flarm Dataport Spec does not contemplate having two traffic sources on the same serial connection, so all the status sentences, such as whether you have good GPS, will either be merged, which will generate unexpected results (e.g. alternating good/bad GPS indications - but no indication which one is which), or you can use the filter function in the K6 MUX to pass status for only one source and never know if the other source is working or not (unless you see a target, which is less than ideal).

There was some other funkiness in the traffic I saw (traffic changing between ADS-R, TIS-B and between 1090-ES and UAT. I suspect this was because they were going in and out of range of my receiver and/or different ground stations, SSR coverage or the service volumes of aircraft receiving ADS-R and TIS-B). We pre-pended two letter codes to each target to identify which band (u for UAT, e for 1090eS) and which service (direct, tIS-B, ADS-r) we were receiving, which was super useful for debugging. These only showed up in ForeFlight. Seems to me that knowing if a target is TIS-B in particular is helpful because the display ought to reflect a much higher position uncertainty.

Andrzej has the source code and, as he said, may take it up. Here is a link to some photos of output on my Oudie and Foreflight.

https://drive.google.com/open?id=0Bw1ChKkWEYLNNEg5ME8zZmNJWGs

As for me, I'm waiting for the new Flarm-licensed devices (e.g. LXNav PowerMouse) that apparently will recognize ADS-R and TIS-B traffic. This will cover the vast majority of my use cases and I think is superior to having to keep PCAS turned on, since it'll give me a rough GPS location for transponder-only and/or Mode C traffic so long as they have radar coverage (or ground station coverage for ADS-R - assuming you have ADS-B Out) along with the proper collision warning and de-duplication that can only be done inside an integrated receiver. Darryl - please correct anything that's incorrect in the above. I just pounded this out and may have been sloppy about some details.

The FAA should've just mandated Mode-S for the US and avoided all this foolishness, but that's spilled milk.

And at times that might be a problem for some traffic displays, not sure, but that easy to test/simulate.

All great stuff if you are technical and hacking on a fun project, I just don't want folks thinking they are getting anything that will just work or that they should rely on to work like a commercial product. /* insert jokes about early PowerFLARM issues here */

If Andrzej is willing to help hand-hold folks that's fantastic.

Seemed to work fine in a busy terminal area (SFO) on my Oudie. I can't speak for the smaller, dedicated displays, which I presume have less processing power.

The other thing I'd point out is running Stratux on a Raspberry Pi draws about 5-6 times as much power as an integrated Flarm device, plus you still have to run Flarm if you are being serious about glider traffic, plus a K6 MUX to combine the traffic (or a separate display, which draws power). That adds up to nearly an amp of current drain, which can be a lot depending on how much battery capacity you are carrying. Andrej was able to turn down the WiFi output power since we weren't connecting to an iPAD for our operations, but that helps only a bit.

Fun project, but it ultimately it will be overwhelmed by more robust, less complicated and less power-hungry solutions. It convinced me that TIS-B and ADS-R service capability is the best path to fill out the current holes in traffic visibility.
