asterix 016 "Independent Non-Cooperative Surveillance System Configuration Reports" edition 1.0 date 2019-07-15 preamble Surveillance data exchange. items 000 "Message Type" definition This data item conveys the message type. element 8 table 1: System Configuration 2: Transmitter / Receiver Configuration 010 "Data Source Identifier" definition Identification of the Ground System from which the data is received. group SAC "System Area Code" element 8 raw SIC "System Identification Code" element 8 raw remark NOTE - The up-to-date list of SACs is published on the EUROCONTROL Web Site (http://www.eurocontrol.int/asterix). NOTE - The SICs are allocated by the national authority responsible for the surveillance infrastructure. 015 "Service Identification" definition Identifies the service being reported. element 8 raw remark NOTE - The service identification is allocated by the system. 140 "Time of Day" definition Absolute time stamping expressed as UTC time. element 24 unsigned quantity 1/2^7 "s" remark NOTE - The time of day value is reset to zero each day at midnight. 200 "System Configuration Reporting Period" definition Data item to indicate the reporting period of the system configuration messages. element 8 unsigned quantity 1 "s" > 1 remark NOTE - The item will be sent periodically (every SCRP) and each time a value change occurs. 300 "Pair Identification" definition The use of a pair identifier in this data item, that is common with its counterpart in ASTERIX Category I015/400, enables direct mapping from the INCS Target Report to the Transmitter/Receiver Pair that contributed to the target report. This is an identifier pointing to a measurement that was created from a specific contributing pair where the Pair Identifier refers to the index that details both the transmitter characteristics (DVB-T, DAB, FM, dedicated etc) and the receiver characteristics. repetitive 8 group PID "Pair Identification" element 16 raw TID "Transmitter Identification" element 16 raw RID "Receiver Identification" element 16 raw 400 "Position of the System Reference Point" definition Position of the system reference point in WGS-84 coordinates. group LAT "Latitude" element 32 signed quantity 180/2^31 "°" >= -90 <= 90 LON "Longitude" element 32 signed quantity 180/2^31 "°" >= -180 < 180 remark NOTE - Positive longitude indicates East. Positive latitude indicates North. NOTE - I016/400 shall only be sent together with item I016/405 “Height of the System Reference Point”. 405 "Height of System Reference Point" definition Height of the system reference point in Two’s Complement form. The height shall use mean sea level as the zero reference level. element 16 signed quantity 1/2^2 "m" > -8192 < 8192 remark NOTE - I016/405 shall only be sent together with item I016/400 “Position of the System Reference Point”. 410 "Transmitter Properties" definition This item provides properties of a transmitter component. repetitive 8 group TID "Transmitter ID" element 16 raw LAT "Latitude" element 32 signed quantity 180/2^31 "°" >= -90 <= 90 LON "Longitude" element 32 signed quantity 180/2^31 "°" >= -180 < 180 ALT "Altitude" element 16 signed quantity 1/2^2 "m" > -8192 < 8192 TTO "Transmission Time Offset" element 32 signed quantity 2 "ns" spare 4 ATO "Accuracy of Transmission Time Offset" element 20 unsigned quantity 1 "ns" PCI "Parallel Transmitter Index" element 16 unsigned integer remark NOTE - Regarding Transmitter Identification: a. Individual channels of a transmitter are considered as separate collocated transmitters. b. A Transmitter ID may be assigned to individual channels of a compound transmitter. i.e. a single multi-channel transmitter may be assigned several Tx ID. c. The Tx ID shall be used in a unique way for a specific SAC/SIC. NOTE - Regarding Transmitter Latitude and Longitude and Altitude: a. The Tx Location and Altitude is the position of the component in WGS-84 coordinates. The vertical distance between the component and the projection of its position on the earth’s ellipsoid, as defined by WGS-84, in two’s complement form. NOTE - Regarding Transmission Time Offset a. Time offset of transmitter compared to the reference transmitter within the single frequency network (SFN). NOTE - Regarding Accuracy of Transmission Time Offset a. The Accuracy of the Transmission Time Offset is the Standard Deviation of the measurement of the transmission time offset between the transmitter channel compared to the reference transmitter within the single frequency network (SFN). NOTE - Regarding Parallel Transmitter Index a. The Parallel Transmitter Index is the identification of the transmitter via index, which is sent in parallel. b. For referring to a one-octet index bits-16/9 shall be set to zero. c. This index shall be used in a unique way for a specific SAC/SIC. d. In a Single Frequency Network the parallel transmitter index is the index of the reference transmitter. 420 "Receiver Properties" definition This item provides properties of the receiver component. repetitive 8 group RID "Receiver Component ID" element 16 raw LAT "Latitude" element 32 signed quantity 180/2^31 "°" >= -90 <= 90 LON "Longitude" element 32 signed quantity 180/2^31 "°" >= -180 < 180 ALT "Altitude" element 16 signed quantity 1/2^2 "m" > -8192 < 8192 remark NOTE - Regarding the Receiver Identification a. The Rx ID shall be used in a unique way for a specific SAC/SIC. NOTE - Regarding the Receiver Location and Altitude (WGS-84) a. The Rx Location and Altitude is the of the component in WGS-84 coordinates. The vertical distance between the component and the projection of its position on the earth’s ellipsoid, as defined by WGS-84, in two’s complement form.
