Pre-Deployment and Usage Guidelines

Important Information: Pre-Deployment and Usage Guidelines

Key Considerations:

Installation Quality and Reception Performance:
The performance of the G-1090 air traffic receiver is highly dependent on the quality of the installation. To ensure optimal coverage and signal reception, please carefully adhere to our installation recommendations, which are available here.
Multilateration Requirements:
A minimum network of five properly installed receivers is required for the G-1090 receiver to support multilateration (MLAT). INVOLI can assist in planning the ideal placement of these receivers to maximize effectiveness. Please note that determining the location of Mode S and Mode A/C aircraft is only possible through multilateration, and the relative positioning of aircraft to the receiver network directly impacts the accuracy of the multilateration process. For further information on multilateration, please click here.
Accessing Air Traffic Data:
To visualize air traffic, access to the INVOLI.live web platform is required. Alternatively, you can use INVOLI APIs to receive data directly from our server and integrate it into any preferred interface. For additional details, please refer to this source.
Internet Connectivity:
If you plan to use a cellular LTE PoE router for internet connectivity, ensure that you select a mobile network operator (MNO) that provides adequate data coverage at the location of the G-1090 receiver.

WARNING:

Aircraft equipped with ADS-B and FLARM systems broadcast their positions at regular intervals, typically once every second. In contrast, Mode S and Mode A/C aircraft only transmit signals when interrogated by a Secondary Surveillance Radar (SSR) operating at 1030 MHz or by a Traffic Collision Avoidance System (TCAS). As a result, the detection of these aircraft is limited to areas where 1030 MHz radar interrogations are present. If necessary, INVOLI can provide a 1030 MHz interrogation transmitter to meet specific customer requirements.

Please note that aircraft without an active transponder (non-cooperative air traffic), with transponders switched off, or those using military transponder modes will not be detected by the G-1090 air traffic receiver.
