Space-based ADS-B Performance
Requirements and Mandate
An aviation industry milestone was reached in
March 2019 with the launch of space-based
Automatic Dependent Surveillance-Broadcast (space-based ADS-B), ground-breaking
technology that provides 100 percent world-wide surveillance coverage.
In Canada, space-based ADS-B is expanding surveillance
to remote areas previously not covered by surveillance and provides greater
situational awareness for air traffic controllers and safety and efficiency
benefits for pilots. Benefits include:
Space-based ADS-B system
Space-based ADS-B will be
used for surveillance in Class A and B airspace according to the dates
identified in the Canadian space-based ADS-B Performance Requirements Mandate
Aeronautical Study recommendations.
Aircraft equipped to meet ADS-B Out
performance requirements will be offered a reduced separation standard within
the designated airspace.
Non-ADS-B Out equipped aircraft
will be accommodated within the airspace until a performance requirements mandate is
CANADA and Transport Canada continue to work together on regulatory changes and
equipment certification. For more information, read the
Update to the ADS-B Performance Requirements Mandate.
Minimum space-based ADS-B
The ADS-B Out avionics
performance standards required to take advantage of space-based ADS-B
separation standards are DO 260, 260A, or 260B or equivalent including antennae
able to broadcast out toward space-based ADS-B receivers.
This type of equipage - an antenna that emits
the signal toward the satellites - is required for space-based ADS-B receivers
to acquire a reliable signal. ADS-B Out transponder solutions that meet NAV CANADA's performance requirements currently available
on the market include antenna diversity.
