INTRODUCTION
INVOLI wishes to thank you for the purchase and use of INVOLI products.

INVOLI provides the necessary data for the safe and efficient integration of drones in the air traffic.
INVOLI.live platform allows users to visualize the position of INVOLI’s drone trackers, together with
the air traffic detected by the INVOLI’s receivers. The drone pilot uses the information provided by the
INVOLI.live system to improve the situational awareness of their drones and react appropriately when
an aircraft is approaching.
Flying a drone could create risks for people, air traffic and other assets. Before flying, the
drone operator has to make sure to know the local rules regarding drone flights and
obtain the necessary authorization to fly the drone(s).
Contact us if you have any feedback on the INVOLI system at [email protected]. If you need
assistance with one of the INVOLI products, contact us at [e-mail].

G-1090 RECEIVER USER MANUAL
INITIAL NOTICE
Thanks for purchasing the G-1090 air traffic signal receiver.
In itsbox, you will find the following items:
●AG-1090 air traffic signal receiver
●AADS-B 1090 MHz antenna
●Asilicon rubber tape
If you have purchased a G-1090For G-1090FA, the following items are also included:
●A FLARM Antenna
With your first purchase at INVOLI, the following software is included:
●An individual license for INVOLI.live BASIC
●An individual license for INVOLI API & Stream
What else do you need to know:
●The reception quality oftheG-1090 isstrongly dependent onthe quality ofthe
installation. Please follow carefully the instructions contained in this manual, in order to
maximize the coverage of your receiver(s)
●If you are going touse anLTEPoE router, check the coverage for your carrier inthe
area you want touse the G-1090 receiver
●Detection ofMode S and Mode A/C aircraft is only possible via Multilateration
●Multilateration is only possible when the signal emitted bythe aircraft is received by
multiple G-1090 receivers (ideally 4,but more isbetter). The configuration ofthe devices
and the position ofthe aircraft have an impact onMultilateration precision.
●Aircraft equipped with ADS-B and FLARM are broadcasting their position atregular
intervals. Onthe other side Mode Sand Mode A/C aircraft broadcast their signal only
when interrogated by aSecondary Radar. Forthis reason, the detection of such devices
is possible only when 1030 MHz radar interrogations are present.
●Aircraft not equipped with a transponder (non-cooperative air traffic) are not visible by
the receiver.
●The data acquired from the G-1090 receiver is visible only via INVOLI.live BASIC,
INVOLI.aero and INVOLI API and STREAM

WHAT ISTHE G-1090 RECEIVER
1. Receiver IP68 box
2. 1090MHz Antenna
3. GNSS Antenna
4. Waterproof RJ45 Ethernet socket (for PoEinput)
G-1090 is Swiss made air traffic signal receiver, developed for fixed exterior mounting, having a
rugged IP68 case that allows the receiver to resist any weather condition. Once the G-1090 is
configured and connected to the internet, it will start transmitting to INVOLI Server the air
traffic messages received. The data provided by the G-1090 is used to feed INVOLI
Multilateration, transforming simple aviation signals (like Mode A/C) into air traffic positions. To
visualise the air traffic, it is possible to use a display platform, namely INVOLI.live, or to integrate
its data stream in a third-party software - like an UTM or a drone ground control software - using
the INVOLI API and Stream.

MULTILATERATION
INVOLI MLAT (MULTILATERATION) is a server-based software that unleashes the true power
behind the G-1090 receivers. Connected to a network of receivers, it calculates and validates the
position of air traffic emitting signals on the 1090 MHz frequency. The algorithm calculates the
position of the aircraft by comparing the times of arrival to the same message to different
receivers. Thanks to Multilateration, it is possible to calculate the position of Mode S and Mode
A/C aircraft, and validate the position of ADS-B aircraft.
It is important to understand that Multilateration results are strongly dependent on the multiple
parameters such as:
1. The number ofG-1090 receivers that receive the same message (the more the better).
2. The position ofthe aircraft relative tothe G-1090 (the more the aircraft is located inthe center
of theG-1090, themore accurate theresult)
3. The initial configuration ofthe G-1090.The G-1090 receivers should be arranged in order to
create a “polygon”, and the area inside the polygon will be where the Multilateration converges
the best. A layout along a line will not give good results in terms.
For point 1., notice that the less powerful transponder will transmit their signal at maximum 10-20
km ofdistance, while the most powerful one can be received up to 400 km ofdistance. This has to
be kept inaccount when choosing the number ofG-1090 receivers and their location.
G-1090 RECEIVER USER MANUAL

INSTALLATION RECOMMENDATIONS
Aviation signals over the 1090 MHz (ADS-B, Mode S and Mode A/C) and FLARM are detectable on line
of sight. This means that your receiver will be able to detect air traffic in the areas which are visible
from the spot where you are going to install the device.
Any obstacle (mountains, buildings, trees and so on) will limit the reception along the obstacle
direction. Therefore, to optimize the coverage, we strongly recommend installing the device ontop of
hills ofmountains, over rooftops ofbuildings, or over light poles, or any tall and isolated structure.
The G-1090 receiver could be installed outdoor orindoor (especially if the building orconstruction
is in wood).
OVER A POLE
The antenna(s) should be placed on the pole, in such a way that the pole itself is not hiding the
antennas (1.). If not possible, it is strongly recommended to place the antennas at least 35 cm of
distance from the pole itself (2. and 3.), in order to avoid reflections of signals. Installing the receiver
behind another device or too close to an emitting device is strongly not recommended.
OVER A BUILDING
The antenna should be placed on the top of the structure (1.). If not possible the receiver should
be placed to optimise the line of sights (2.). Installation into a concrete building (3.) are not
recommended. There is no problem in installing the receiver into wooden structures.

INSTALLATION PROCEDURE
Instructions on mounting and securing the mounting kit to the enclosure and the bearing pole.
*If needed The G-1090 can be mounted on ahorizontal pole by not using the 90° angle converter
part.
1. Fix the included cross bracket onthe bottom ofthe enclosure with four M6*12 bolts.
2. Place two pieces of the clamp around the pole and tighten them with the included M6*110
bolts, washers, and nuts.

3. Connect the pole clamp and the cross bracket by securing the last piece of the mounting kit in
place using M6*30 bolts, washers, and nuts.

CONNECTION TO A NETWORK
All your Ethernet cables should be at least CAT6 and shielded.
DIRECT
If your network isequipped with Power over Ethernet (PoE), simply connect an ethernet cable the
G-1090 ethernet socket. Assoon asthe connection ismade, the device will turn on.
The G-1090 uses DHCP to find its own dynamic address over a private network. Please contact us if
you need information for firewall configuration.
PoE ROUTER
If your internet access is not equipped with PoE, you can purchase a PoE injector (available on INVOLI
catalog of spare parts and accessories). The injector has to be connected to the internet with
an ethernet cable and to the power. Then, simply connect the ethernet cable from the G-1090 and
the receiver should turn on.

G-1090 RECEIVER USER MANUAL
LTE PoE ROUTER
If you are installing a G-1090 where there is no access to internet you can purchase a PoE LTE router
(available on INVOLI catalog of spare parts and accessories). The installation is similar to the one of
the PoE router, with the difference that you have to install in the router one or two SIM cards (for
redundancy) and internet access will be provided over 4G LTE.
To better protect the Ethernet cable gland and the antenna connector from the weather, you can cover
them with PVC tape.
Clean the surface area of the connector that will be wrapped. Wrap a layer of PVC tape with a 50%
overlap according to the rotation direction of the connector. Continue wrapping the PVC tape to about
10 mm below the end of the connector.
