What is the analysis of ADS-B access configuration? in view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

Access ADS-B via multicast:

1. Because the network needs to be initialized when the trackasmla.linux process starts (the process needs to be started after the network is normal, otherwise the network initialization will fail when the trackasmla.linux process starts), so to configure multiple ip addresses for the network card bond0, you need to change bond0 to bond0:x (x is 0mur255, such as bond0:0 or bond0:1, etc.). Bond0:x is called virtual network interface, which is built on the network interface (bond0).

2. In the trackasmla.ini configuration file:

[recv0]

Ip=196.168.2.51

Port=56060

Multip=233.1.21.1

Mla=MLA0 MLA1

[recv1]

Ip=197.168.2.51

Port=56061

Multip=233.1.21.1

Mla=MLA2 MLA3

So configure IP of bond0:0 to 196.168.2.51, read ADS-B data from port 56060 to simulate MLA0/1 access system; configure IP of bond0:1 to 197.168.2.51, read ADS-B data from port 56061 to simulate MLA2/1 access system.

3. In the trackasmla.ini configuration file:

[MLA0]

Key=196.168.2.23

Mid=3

Cid=0

Mid=3 refers to the fourth MLA (MLASwitch=3) in the system, and the first three MLA (defined as MLA-A,MLA-B and MLA-C in radar.ini) are used to access 16-way radar:

* define the port of MLA-An in radar.ini as [PORT_001] to [PORT_016]; MLA device number MLASwitch=0

* the port of MLA-B is from [PORT_017] to [PORT_032]; MLA device number MLASwitch=1

* the port of MLA-C is from [PORT_033] to [PORT_048]; MLA device number MLASwitch=2

Cid=0 stands for MLAChannel=0, so:

* mid=3,cid=0 is defined in radar.ini [PORT_049]

* mid=3,cid=1 is defined in radar.ini [PORT_050]

ADS-B is defined as [RADARPORT_17] in radar.ini

RadarID=17

UsedFlag=1

IsFromAorB=1

PortNoA = 49 / / ADSB-A channel monitored by SMPC

PortNoB = 50 / / ADSB-B channel monitored by SMPC

PortNoC = 51

PortNoD = 52

IsAutoFromAorB=1

IsFusionFlag=1

CoastNum=3

4. Set [RADAR_17] for radar in radar.ini. Set [RADARPORT_17] for ADS-B channel corresponding to ADS-B,RadarID=17.

This is the answer to the question about the analysis of ADS-B access configuration. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more relevant knowledge.
