supports Working Group 4 of RTCA SC-186.
ASA MASPS
Materials: To download any available materials from the
development efforts of the ASA MASPS (RTCA/DO-289),
follow this link to a table of
all WG-4 ASA MASPS meetings.
Working Group 4
of RTCA SC-186
was realigned into two groups with two different tasks in November,
2004. WG-4A supported the development of the ASA MASPS document.
WG-4B supports the development of the ASAS MOPS document. Working Group 4 is
co-chaired by Jonathan Hammer, of The MITRE Corporation/CAASD and
Steve Koczo, of Rockwell Collins. For questions or information about
WG4 activities, please contact Jonathan at <jhammer@mitre.org>.
Working Group 4A is responsible for
the development of requirements
of end-to-end systems that can support and perform aircraft-based
surveillance applications enabled by ADS-B. This work
includes safety and performance analyses to determine the requirements
for safe and efficacious use of these applications. WG-4A
completed the initial version of the Aircraft Surveillance
Applications (ASA) MASPS in December, 2003 which was published as RTCA
DO-289.
An international
harmonization effort is underway for some ASA application descriptions
and requirements currently included in the ASA MASPS. This work is
being done through the RTCA and Eurocae Requirements Focus Group (RFG). WG-4 members are supporting this effort,
which is expected to result in a modified, jointly published ASA MASPS. WG-4A
will be modified at this time. For more
information on the RFG and its activities visit the
RFG page on this web site.
Working Group 4B
of RTCA SC-186 is responsible for requirements development for the
avionics equipment necessary to support ASA applications as defined
in the ASA MASPS (RTCA/DO-289).
Working Group 4B
is co-chaired by Jonathan Hammer, of The MITRE Corporation/CAASD and
Sethu Rathinam, of Rockwell Collins. For questions or information
about WG-4 activities, please contact Jonathan at <jhammer@mitre.org>.
Currently, WG-4B is developing requirements for the
Airborne Separation Assurance Systems (ASAS) Minimum Operational
Performance Specifications (MOPS). WG-4B sub-groups are
developing requirements for the three major sub-systems of ASAS.
The Surveillance Transmit Processing (STP) sub-group developed and
published
requirements for the STP, which processes own-ship data as
necessary prior to transmitting it within ADS-B broadcasts.
The Airborne Surveillance and Separation Assurance Processing (ASSAP) sub-group is
currently developing requirements for ASSAP, which will process received
surveillance data and other information as necessary to perform ASA
applications. The Cockpit Display of Traffic Information (CDTI)
subgroup is currently defining requirements for the CDTI, which serves as the flight crew
interface for all ASA applications and equipment.
These three ASAS
sub-systems will define the specifications for the aircraft-based
equipment required to support the ADS-B applications. The ASAS MOPS
will be a lower level document of the Minimum Aviation System
Performance Standards (MASPS) for Airborne Surveillance Applications
(ASA), which was completed by Working Groups 1 and 4(A) in late
2003. The ASAS MOPS will specifically support those applications
included in the ASA MASPS.
The WG-4B sub-groups generally meet concurrently and share some joint
sessions. As such, the meeting minutes and schedules are
intermingled, and can be found above.
