Affordable, easy-to-install solution without GPS

Stratus ES was built without GPS in order to provide affordable ADS-B Out to aircraft owners who have already invested in WAAS GPS. Stratus ES will make an aircraft rule-compliant when paired with any of the following navigators: Garmin GNS 430W/530W, GTN 650/750, Avidyne IFD440/540.

  • ADS-B Out transponder meets the 2020 FAA mandate
  • 1090ES technology – no altitude or geographic limitations
  • Connect to your existing WAAS GPS for an all-in-one solution
  • Replacement for your Mode C transponder – upgrade your old analog transponder


It’s not enough to have affordable hardware; the right ADS-B solution has to be affordable to install as well.

  • Fits in standard transponder slots – typically 50% less to install than remote mounted models
  • All-in-one unit - no remote boxes or control heads required
  • Complete kit includes all mounting hardware


Stratus ES can also connect to a portable ADS-B In receiver, including Stratus 3, Stratus 2, Stratus 1S/2S, Dual XGPS 170/190, and Garmin GDL 39/39 3D. This makes it a complete system, with subscription-free weather and traffic. Plus, you retain the valuable backup capability of a standalone ADS-B receiver.

  • Complete traffic picture in ForeFlight
  • Better ADS-B reception
  • Full-time power source
  • Works with Stratus 3, 2, 1S and 2S (choose install kit below)
  • Also works with Dual XGPS 170/190 and Garmin GDL 39/39 3D (requires separate kit)

If you don't have a portable, but would still like to receive ADS-B In data, there is another option. Stratus 3i is a remote-mount, non-certified ADS-B receiver that connects to Stratus ES. While it won't work on its own (there is no internal battery or GPS receiver), it is an affordable way to add ADS-B In to your airplane. You'll see weather, traffic, GPS position and backup attitude on your iPad, all send via WiFi. Simply select Stratus 3i above ($500).

Stratus ES is made in the USA and includes a 5-year warranty. 

Bezel Width6.38 inches (162 mm)
Bezel Height1.69 inches (43 mm)
Rack Width6.32 inches (160.4 mm)
Rack Height1.65 inches (42 mm)
Depth from back of bezel to end of strain relief on rack (not compensating for wire bend radius)10.75 inches (273 mm)

Stratus ES Unit Weight2.75 lbs. (1.25 kg)
Stratus ES Total Installed Weight (Transponder with rack and connectors)3.29 lbs. (1.49 kg)


Important Note

  • Stratus ES should be installed by an approved Appareo dealer - find a dealer here
  • Unit will be shipped to installer.

I was sold on your product until I realized it had to be installed by one of your approved installers. Every airplane owner has "their guy" they have used for years to maintain their individual aircraft. Someone that knows every detail of the aircraft. It is unfortunate that my mechanic will be unable to install this product. He installed my Garmin 430W, STEC 30 Autopilot, and JPI engine monitor. I'm sure after looking at the install manual, he is more than capable of installing the tray. antenna, and harness in 8 hours, not 20. Very unfortunate, I really felt like this product was my answer. will the product be offered to individual purchase before 2020?

Can the ADS-B out Transponder be shipped to my AI and installed by him and then test flown ?
cessnadad on Dec 10, 2018

Are you still requiring that it be installed by your dealers?
Scott W on Mar 11, 2020
BEST ANSWER: Certified Avionics are required to be installed by an avionics shop. The manufacturer required us to ship to a dealer/installer.
Does the Stratus 3i remote mount receiver work with FltPlan Go?
A shopper on Jan 11, 2020

I have an existing Garmin 327 trans.and a Garmin 430w solution??
richard d on Dec 28, 2019
BEST ANSWER: Yes, this is a replacement for the 327 and meets the requirements.
could I use my sentry vs the stratus?
Avery P on Jul 15, 2019
BEST ANSWER: Yes, you can use the Sentry instead of the Stratus. The Stratus will just integrate with the ESG.
Will this work with Stratus 3 as well?
Jackson on Mar 16, 2019
BEST ANSWER: Yes, it can be paired with the Stratus 3.
I have a 430 WAAS which can be used for the ES but is it better to get the ESG for the integrated WAAS just in case that the 430 WAAS becomes inop for different reasons. Also is the ES or ESG a replacement for a Narco 150 in a PA 34-200?
Hannery L on Feb 5, 2019
BEST ANSWER: You can purchase the ESG, it means that you will have an independent WAAS signal for the transponder. It will also mean more time to install. The ESG or ES is a replacement and can be placed in a PA 34-200.
I have a stratus 2s and foreflight. If i get the Stratus ES ADS-B Out Transponder (certified)...Do I need to get an antenna or harness or does everything come with it or can I use the existing cheapy transponder antenna?
A shopper on Jan 14, 2019
BEST ANSWER: You do not need to have a harness. You can choose to use a harness and have the Stratus unit powered by the ship's power and use the ship's antennas for GPS and ADS-B (uses the transponder antenna)

This requires the wiring harness, the 2s integration cable, and the ADS-B input cable.
will this work with a garmin 430W?
A shopper on Nov 23, 2018
BEST ANSWER: Yes, it will work with the Garmin 430W.
I have an apollo GX55 GPS will it work to interface with this unit? Would I need anything else? Otherwise what is the most cost effective way to get ADS B out? Currently I have an AT50A Narco.
Ronald on Nov 12, 2018
BEST ANSWER: The Stratus ESG will not interface with the GX55 GPS. This using includes a WAAS GPS antenna that is required for the 2020 mandate. I would recommend that you replace the older Narco with a new transponder.
my 496 is waas will this work with it?
ian m on Apr 29, 2018
BEST ANSWER: No, This unit will not use the GPS from the 495. The ESG transponder includes a WAAS GPS.
Why does it have to be shipped to an installer?
A shopper on Dec 29, 2017
BEST ANSWER: This is the manufacturer's policy.
