    Successful EGOA demo and workshop (Published by Roger Li, 2005-10-26)

    The EGOA project wishes to thank all the participants who helped to make the joint EGOA/CASCADE demo/trial/workshop a success. More than 60 partcipants from all over Europe attended the workshop and 16 ADS-B equipped GA aircraft participated in the demo flights. The presentations will be uploaded to the egoa website no later than Thursday October 27.




    Welcome to Demo October 26 (Published by Roger Li, 2005-09-28)

    The LFV ANS Group and EUROCONTROL are delighted to invite you to our joint live trial and workshop on the 26th of October, at Norrköping Airport in Sweden.

    The trial addresses Operational Improvements from better Situational Awareness for ATC and Air Crew using ADS-B (Automatic Dependant Surveillance Broadcast), feeding both LFV implementation plans and EUROCONTROL CASCADE ADS-B Package I application validation. The event is a possibility for you to participate in the trial activity “hands-on” and witness it both from ATC and pilot (on-board) view. Above all, the aim is to bring you into the trial and the discussions at the workshop.

    We believe the event will be of interest for a wide audience, ranging from operational air traffic controllers and pilots to those involved in ADS-B applications (such as ATSA-AIRB and ADS-B-RAD) development and implementation. Over 10 ADS-B aircraft will be airborne (weather permitting). There is a possibility to fly along in some of them (limited number of seats).

    The enclosed invitation gives you further information and practical details about the event, to which you need to register on a “first come, first served” basis, no later than 12th October.

    We extend a warm welcome to all of you and hope to see you there.

    You can download ALL the info in a zip-file if you click here.

    You can download the invitation in a pdf-file if you click here.

    FFK takes part in the EGOA trials (Published by Lars Holmström, 2005-09-07)


    FFK (Volontary Flying Corps) is a Swedish voluntary government controlled organization which utilizes civil general aviation aircraft to perform various surveillance and environmental tasks. The pilots are recruited among members of flying clubs and aircraft owners. On a voluntary basis aircrew fly missions including maritime patrol and sea search. Also border patrols are made.

    Recently FFK has got a new way to supervise the flights of the small general aviation aircraft used. Flight safety can also be increased. In the headquarters at Skavsta airport it is possible to follow the flights in real-time on a PC. The aircraft used by FFK are often equipped with ADS-B/VDL mode 4* transponders being part of the ongoing EGOA trials conducted by the Swedish CAA.

    Each participating aircraft has a transponder which every few seconds automatically transmits a GPS derived position report. The transmitted position reports are received by the CAA ground receivers and are distributed on a ground data network. FFK at Skavsta is connected to the network and can follow the progress of FFK flights on a PC screen. The trials are at the moment planned to go on for more than a year.

    * ADS-B/VDL mode 4= Automatic self reporting of position etc. using a VHF datalink





    FIS-B up and running at Norrköping airport (Published by Roger Li, 2005-05-12)

    Since a couple of weeks the FIS-B service is now up and running at Norrköping airport. From the Norrköping ground station MET REPORTS are being broadcasted, available for the pilots in text format on their CDTI:s.

    Next step is to implement the service at all four airports in Östgöta TMA that participates in the EGOA project.




    Successful Multimode Radio Installations & Test (Published by Roger Li, 2005-04-08)


    RTX6040 Multimode Radio installation in SE-XMF

    During this week the RTX6040 Multimode Radios combining 8.33/25 kHz Voice COM and ADS-B via VDL mode 4 have been installed.

    On Friday the 8th of April six aircraft and three vehicles participated in a test and demonstration in Östgöta TMA. Both Multimode Radios and "ADS-B only" transponder equipped aircraft participated.

    The demo flights was presented live via internet at the EUROCONTROL Briefing day for Business and General Aviation (report found here) as well as on a joint Swedish-Russian event at Malmö-Sturup airport in southern Sweden.




    EGOA project experiences so far (Published by Lars Holmström, 2005-04-07)

    ADS-B transponders and in most cases with a cockpit display (CDTI) have been and are currently being installed in aircraft operating in Östgöta TMA i Sweden. Some of the transponders are ADS-B only transponders while some are Multimode Radios with combined 8.33/25 kHz Voice COM and ADS-B via VDL Mode 4, all in one small box. So far the system has performed well to all expectations. The air controllers are not yet fully trained to use ADS-B but as more transponders are “on the air” more and more data is recorded and experience collected. Monthly reporting is made by all participants and this is of great value. A number of demonstrations of the system have been made and more are planned. Next upcoming demo is on April 8, live in Östgöta TMA and via Internet connection at EUROCONTROL in Brussels.




    Presentation software available for participants (Published by Roger Li, 2004-12-17)

    The ADS-B presentation software Multi Mode CATS is now available for those participating in the EGOA-project. This far Linköping Flying Club has had the presentation software installed, enabling the people on the ground to follow the flights of the ADS-B equipped aircraft via an internet connected PC.

    Now the Multi Mode CATS software is available for everyone participating with an ADS-B equipped aircraft in the EGOA project.

    To get your copy of the software please contact roger.li@lfv.se.

    Successful flights! (Published by Roger Li, 2004-08-12)


    Four ADS-B equipped aircraft.


    The first major flight test involving several aircraft was conducted successfully at Malmen airport on monday evening the 9th of August


    In Malmen TWR the air traffic controller could follow all aircraft on the air traffic display showing both SSR equipped aircraft as well as ADS-B equipped aircraft.

    After the test everyone involved was very satisfied with the result.

    ADS-B displays now in towers (Published by Roger Li, 2004-06-17)


    Air traffic controller Anders Carlsson in Skavsta TWR

    On the 15th and 16th of June the towers at Stockholm-Skavsta, SAAB and Malmen airports got their ADS-B presentation units installed. The system is the i-acs system from AerotechTelub which is already used at many Swedish airports. The difference with the displays installed as a part of the EGOA project is that these units also support ADS-B, of course alongside with SSR and PSR which was also supported in previous versions of i-acs.

    EGOA at Briefing Day for General Aviation (Published by Roger Li, 2004-03-05)

    The annual “Briefing Day for General Aviation” was held at Eurocontrol ,Brussels, on the 27:th of Februari. A small exibition was held outside the conference room by the operational responsible of the EGOA project, Per Wilhelmsson. Besides the information about the EGOA-project a large diplay showing ADS-B traffic at Arlanda airport was demonstrated. The recording showed ADS-B transponder equipped busses at Arlanda airport and also data from the ground movement radar at Arlanda.

    Among the people that visited the EGOA exibition was Phil Boyer, President of AOPA, who showed a great interest in the ADS-B technique.

    At the Briefing Day 2005, the EGOA project hopes to be able to show a live picture of ADS-B equipped aircraft flying in Östgöta TMA in Sweden.

    The EGOA project has had ongoing lobbying activities since march 2003. These activities have now resulted in that more than 40 aircraft has been proposed to participate in the project by their different owners.

    Even though there will not be much more than 40 installed aircraft in the project we still encourage flying clubs and aircraft owners to flag their interest, it is not yet decided which 40 aircraft that will be selected.

    The owners of the first ten aircraft to be installed will be notified in december.
