Hector Posted July 29, 2014 Report Posted July 29, 2014 Interesting new product (2015 release) from the folks that make the Stratus receivers. This is an all-in-one transponder with extended squitter and built in WAAS GPS. Intended to be a direct replacement for your existing transponder. It will need to be connected to a GPS antenna but it may be attached to an existing WAAS antenna if you already have one. Makes you fully ADS-B out compliant with one box. The stratus will also attach to this transponder via a cable. Your stratus will then utilize the better GPS signal from the transponder and it will also use the transponder antenna for ADS-B in for better signal reception. This should give you a lot more options on where to place your stratus box since it will no longer need a GPS signal nor will it need to receive the weather info via its internal antenna. Anyway, I think this is just an example of potentially various options for ADS-B solutions that we are likely to see in the next couple of years. Price is expected to be comparable to existing transponders but they did not quote a price. 5 Quote
N201MKTurbo Posted July 29, 2014 Report Posted July 29, 2014 2020 is starting to look better all the time! Quote
Hector Posted July 29, 2014 Author Report Posted July 29, 2014 Should have also mentioned that when the Stratus is connected to the transponder it will also receive power from the transponder so the battery in the Stratus will remain fully charged Quote
Hector Posted July 30, 2014 Author Report Posted July 30, 2014 I do not. I saw their prototype unit at their booth here in Oshkosh. Sorry, should have taken a picture to post here. I was too tired and brain dead by the time I got to their booth. Quote
PaulB Posted July 30, 2014 Report Posted July 30, 2014 Wonder what the cost is and if it interfaces with the 530. Those are my current hold ups Quote
carusoam Posted July 30, 2014 Report Posted July 30, 2014 Connecting a portable to another panel mounted device sounds a bit fuzzy on the approval scale??? Usually testing and stated capabilities are part of the approval process, no? Getting a non G device to connect with a G device sounds near impossible, until you buy it. Then it becomes impossible. Just thinking out loud, -a- Quote

Just thinking out loud, -a- I guess we will see, however, in this case the portable (stratus receiver) is only receiving information from the transponder. It is a one-way transfer of data only, I guess no different than some folks have a Garmin 496 connected to a Garmin panel mounted GPS Sent from my iPad using Tapatalk HD 1 Quote
carusoam Posted July 30, 2014 Report Posted July 30, 2014 My concern is more receiving power than anything else. Accidentally shorting something and letting the smoke out would be bad... Two devices designed to work together sounds interesting. A portable that receives power from a mounted device is still portable... (I hope) We used to not be able to mount portable equipment into the IP rules are so slow to change... Best regards, -a- Quote

Best regards, -a- All of the portables today can run off of ship power through the cigar lighter. Building in a power circuit to support a portable would be an easy add-on and considering that we are seeing approvals for uploading and downloading of flight plans into certified units from iPads through WiFi and Bluetooth, be considered minor.

Alan Fox Posted July 30, 2014 Report Posted July 30, 2014 Probably not going to get certified... Talked to the guys at trig , and the adsb out MUST have WAAS position from a TSOd GPS source , the only ones I know of are Garmin , Avidyne , and King..... Quote

Except for our experimental cousins flying in the same airspace as we do. Quote

Talked to the guys at trig , and the adsb out MUST have WAAS position from a TSOd GPS source , the only ones I know of are Garmin , Avidyne , and King..... I think the point is that their transponder has a built-in WAAS GPS that will get its signal from a permanently installed GPS antenna. Not sure how this is different than any other TSOd unit. If they are successful, and I don't see why they could not get it done, it becomes an all-in-one box. The stratus attachment is just to get your WIFI functionality and ADS-B in. Quote
Alan Fox Posted July 30, 2014 Report Posted July 30, 2014 Again the guys at Trig said that getting a TSO for a waas gps is next to impossible.... It took avidyne 5 years at least , and King over 7 years........ And it doesn't matter if its experimental , still need a tso for this... Quote

It took avidyne 5 years at least , and King over 7 years........ And it doesn't matter if its experimental , still need a tso for this... I know nexgen is going to used the broadcasted GPS for separation and hence the reason it is so difficult and important that the GPS position be correct. But, what happens if you lose satellite coverage, I wonder how long it will take for ATC or TAWS/TCAS systems to figure it out and how will they handle it? Quote
Piloto Posted July 31, 2014 Report Posted July 31, 2014 Unlike plain vanilla WAAS GPS a TSOd WAAS/GPS needs to have positional integrity check capability, specially during an IFR approach. But I do not see a problem getting the position info from a TSOd GPS navigator. After all it does not require adding another GPS antenna. TCAS does not rely on ADS-B for traffic detection. The ADS-B position updates are too slow for issuing accurate Resolution Advisory (RA) warnings, specially when converging at 800Kts. ADS-B position updates are at 1Hz while TCAS interrogation rates can be as high as 1000Hz. There is no RA capability between two ADS-B only converging planes. José Quote
Alan Fox Posted August 7, 2014 Report Posted August 7, 2014 The GDL88 is certified , but is it certified for 2020 without the TSOd waas navigator , Or is it the same receiver as the gns gtn series using the same tso..... Quote
carusoam Posted August 7, 2014 Report Posted August 7, 2014 Didn't we have a Garmin guy here? (from the company that is) It is getting complicated to decide on a pair of nav/coms... Best regards, -a- Quote

larryb Posted August 7, 2014 Report Posted August 7, 2014 The gdl88 comes in different favors. One without internal gps. That one needs a waas GPS in the panel. They have another with integrated waas that is a single box solution for 18,000 and below. You can also have both a gdl88 and an es transponder to give you capability above 18,000 feet. The gdl88 gives you "in" for your certified gear. Quote
Alan Fox Posted August 8, 2014 Report Posted August 8, 2014 I just read up on the gdl 88 , it will need a tso'd waas position source to meet the mandate.......In plain English , It will work in and out , but to be legal for the mandate it will need to be fed waas position info from a TSO'd waas gps...
