On April 21st 2021, the Commission Implementing Regulation (EU) 2021/666 was published, amending SERA.6005 by the sub-article (c):

Manned aircraft operating in airspace designated by the competent authority as a U-space airspace, and not provided with an air traffic control service by the ANSP, shall continuously make themselves electronically conspicuous to the U-space service providers.

On December 16, 2021, EASA further published NPA 2021-14: “Development of acceptable means of compliance and guidance material to support the U-space regulation” (“AMC/GM”). Section 3.3 introduced in more detail the AMC and GM for implementing above SERA.6005 (c) article.

AMC1 SERA.6005(c) in point (a)(3)(ii) specifies SRD-860 frequency band as one of the three means of transmission of electronic conspicuity information.

Appendix 1 to AMC1 SERA.6005(c) further specifies ADS-L MESSAGE GENERATION FUNCTION i.e. the minimum set of parameters that should be transmitted and a set of parameters that may be transmitted optionally, termed “ADS-L” thereafter.

Novamedia Technology has taken the initiative to develop a fully functional prototype of an ADS-L beacon while concurrently working on a low-cost ADS-L monitoring system.

Our first ADS-L Beacon prototype

Novamedia Technology has developed its first full working ADS-L beacon just five months after EASA published the first technical specification “Technical Specification for ADS-L transmissions using SRD-860 frequency band
(ADS-L 4 SRD-860)”
