Portable ADS-B In/Out Solution

Order SkyEcho


SkyEcho is the world’s first approved, portable, battery powered ADS-B transceiver.  Offering ADS-B-In and Out on 1090ES, it exceeds the minimum capability required for use in the UK as a CAP 1391 Intermediate ECD.  SkyEcho features a precision SBAS GPS receiver and integrated barometer for position and pressure altitude reporting.  The integrated Wi-Fi allows an Electronic Flight Bag to display received traffic information and the onboard battery keeps the cockpit free of cables and clutter.  Increase safety in the air using SkyEcho for enhanced situational awareness today.  See our FAQ for more information.

Looking for the original SkyEcho ATT-20B?  You can find it here.


Weighing just 200 grams SkyEcho receives surrounding traffic information including aircraft type, position, altitude, course and speed in real-time.  Traffic data is sent via Wi-Fi to an EFB (Electronic Flight Bag) such as Skydemon or a GDL90 compatible EFIS for display.


  • 1090ES reception (1090 MHz) from aircraft equipped with 1090 MHz Extended Squitter transmitters
  • High integrity SBAS and RAIM enabled GPS provides position data for ADS-B Out transmissions

  • Traffic information from 1090ES are correlated to provide a coherent view of nearby aircraft
  • ADS-B receiver broadcasts traffic information over Wi-Fi to compatible flight applications and EFIS displays

  • Integrated rechargeable battery provides hours of flight time

Frequently Asked Questions

Can I use SkyEcho in the U.S. 2017-03-27T22:38:04+00:00

No.  The SkyEcho is currently approved for use as an ADS-B out device in the U.K. under the innovative CAP 1391 program.  Use of SkyEcho in the United States is prohibited by the FCC and FAA.

What is Electronic Conspicuity? 2017-03-26T00:08:18+00:00

Electronic Conspicuity (EC) is an umbrella term for a range of technologies that, in their most basic form, transmit the position of the host aircraft to other airspace users operating compatible equipment. More advanced devices can also transmit and receive, displaying and alerting pilots to other/conflicting traffic who have compatible EC devices. EC devices turn the traditional ‘see and avoid’ concept into ‘see, BE SEEN, and avoid’.  You can learn more about the program on the UK CAA’s Electronic Conspicuity page.

EC devices are intended for voluntary carriage on registered and non-registered UK Annex II  aircraft, non-complex EASA aircraft of <5700kg MTOM and for gliders and balloons (including those covered under ELA 1 and ELA 2) within uncontrolled UK airspace.

An EC device cannot be used at the same time as a transponder and it doesn’t replace the need for a transponder when required by airspace/flight rules. If your aircraft is fitted with a working transponder, you must switch off the transmitter function of your EC device.  SkyEcho provides this functionality.

What does “portable” mean with regards to the SkyEcho? 2017-03-26T00:12:34+00:00

The SkyEcho is a portable device that you can take with you from aircraft to aircraft and does not require physical or electrical installation into the airframe.  EC devices use a 24-bit address in the same way as a transponder.  This usually forms part of an aircraft’s Certificate of Registration.  However, as an EC device is designed to be portable and to also be used by unregistered aircraft, the 24-bit address will be programmable by the user.   The device is small enough to sit on your glare shield and fit easily in your flight bag.

Refer to the guidelines under the section titled “How to use 24-bit addresses with Electronic Conspicuity Devices” section available on the Electronic Conspicuity page.

What kind of range does SkyEcho have? 2017-05-04T09:09:11+00:00

The SkyEcho is both an ADS-B IN (receive) and ADS-B OUT device.  Range is a function of transmit power. Depending on the output power of other aircraft, you will be able to SEE other aircraft over 270km (~150 NM) away.  SkyEcho has a transmit power of 20W on 1090MHz (1090ES).

What frequency does it use? 2017-03-26T00:18:25+00:00

The ADS-B standard frequency for most of the world (all but the U.S.) is 1090Mhz.  In the U.S. 1090Mhz as well as 978Mhz is used.  SkyEcho transmits and receives on 1090Mhz.

Can I see other aircraft with SkyEcho? 2017-03-26T00:19:56+00:00

Yes!  SkyEcho has built-in Wi-Fi hotspot that allows you to connect and display nearby traffic on a compatible app.  SkyEcho uses a common interface format called GDL 90.  As of now (Nov 2016), SkyDemon, Foreflight, Avare, Naviator, iFly 740 and FltPlan Go are a few of the compatible applications.  If you are a developer and would like to confirm compatibility please contact us.

Can other aircraft see me? 2017-05-04T08:05:23+00:00

Yes.  Any aircraft equipped with ADS-B IN capability can see you.  This includes other EC devices as well as installed avionics, and other third party systems such as the Garmin GDL39, PilotAware and Flarm.

Can ATC see me? 2017-03-26T00:28:29+00:00

Yes ATC can see you if you are transmitting within range of an ATC ADS-B ground station radio.

What are the limitations? 2017-03-26T00:27:20+00:00

EC systems are designed for aircraft to aircraft visibility. An EC device will not meet standards to allow you to enter controlled airspace. Additionally, if you have an installed Mode S transponder in your aircraft, you will have to turn off the transmit function of the SkyEcho or the Mode S transponder. This is standard for all EC devices and is designed to keep you from presenting a “double target” on ATC displays. The SkyEcho configuration app allows you to turn off the transmit function while still being able to receive traffic for display on the compatible app.

Does it have an app? How do I view nearby air traffic in my cockpit? 2017-03-26T00:27:43+00:00

The echo iOS app is a configuration app that allows you to configure device settings, including setting the ICAO address and enabling/disabling the transmit function. The echo iOS app is not a moving map or traffic display app. For this functionality, you will need to pair with a compatible application such as SkyDemon or your preferred EFB.

Do I have to reconfigure it if I move to a different aircraft? How? 2017-03-26T00:27:58+00:00

If you are moving from one aircraft to another of similar size and type, you should not have to change anything.  However other configuration fields exist for type of aircraft (light, glider, rotorcraft, etc.) as well as aircraft size, etc.  EC devices are intended for voluntary carriage on registered and non-registered UK Annex II  aircraft, non-complex EASA aircraft of <5700kg MTOM and for gliders and balloons (including those covered under ELA 1 and ELA 2).

Where is this going? 2017-03-26T00:28:00+00:00

We hope worldwide!  Regulatory agencies are viewing EC devices as an affordable solution to increase the safety of national airspace systems by providing pilots with greater situational awareness.  The UK is the first, EASA soon to follow – from there – who knows?  As far as the product goes, we will plan our roadmap based on feedback from our customers and hope to deliver a more integrated product in the future.
