DFMC GBAS Ionosphere Monitor Validation by Flight Data
This paper introduces results of DFMC GBAS ionosphere monitor validation by using flight data obtained with the DFMC GBAS testbed.
A DFMC GBAS testbed has been installed in Ishigaki, Japan and is being operated continuously. Data obtained in two flight data collection campaigns were analyzed to evaluate the ionosphere monitor metric. Divergence-free smoothing (600 seconds) outperforms single-frequency smoothing (100 seconds), but carrier-phase-based monitoring was even better and promising. Flight data under strong ionospheric conditions were obtained in the flight data collection campaign in October 2023 and are being analyzed. Next flight campaign is being planned in March 2024.

SBAS RANGING SOURCE IN GBAS
This working paper discusses the use of SBAS ranging source in GBAS. For DFMC GBAS, use of SBAS ranging sources are proposed to be excluded. This paper identifies descriptions related to the SBAS ranging source in existing GBAS SARPs, ICD, and MOPS for GAST C and D. Although there is no known implementation of GBAS with an activated SBAS ranging source function, it is not recommended to remove SBAS ranging source entirely from GBAS, because a lot of work would be required if they were removed.

Not supporting SBAS ranging in DFMC GBAS should not have backward compatibility issues, because it is an optional in existing GBAS (GAST C and D).

Analysis of the 1030-1090 Signal Environment in Japan
It is necessary to monitor the usage of the 1030/1090 RF network to regulate its use properly. But monitoring of the 1030/1090 MHz frequency band is complex. Therefore, TSG had developed the RF Measurement Guidance Material to support RF measurements. This working paper provides measurement result examples of 1030/1090 MHz signal environment in Japan conducted by airborne measurements.

Doc 9924 Change Proposal for a New Common Clock Architecture
Electronic Navigation Research Institute (ENRI) has been investigating a Multilateration (MLAT) system employing a Radio-over-Fiber (RoF) technology for airport surface surveillance. RoF enables transmission of RF signals from a remote receiver station to a central site. This architecture using RoF would have several advantages over existing airport surface MLAT systems. This paper presents a draft of change proposal of Doc 9924 regarding a new common clock architecture.

Doppler shift of QZS-7 satellite
At EUOCAE EG 62 (50th), discussion was made about Doppler Shift of QZS-7 satellite for MSAS inside the Service Area of Japan taking initial acquisition of L1 GPS signal into consideration. Then it was also pointed out that there seems to be inconsistency between the texts of existing SARPs and MOPS in this regard. This paper summarizes extending analysis on this issue of MSAS and associated change proposal of SARPs Annex 10.

Additional-Time in Terminal Airspace (KPI08)
The joint work on operational air navigation service performance of the Civil Aviation Authority Singapore (CAAS), Federal Aviation Administration (FAA), AEROTHAI, JCAB and EUROCONTROL is being conducted. The joint work provides a demonstrated implementation for the key performance indicators. In order to capture tactical arrival control measures (sequencing, flow integration, speed control, spacing, stretching, etc.), an Arrival Sequencing and Metering Area (ASMA) is defined; the “additional” time is used as the indicator for the level of inefficiency in the area. In this study, the computation method of the additional time based on the entry angle bins in the ASMA is studied and compared with other method.
