NEXT GENERATION DIRECTION FINDING AOA 100

Cross Section AoA / Heatmap AoA Multi-Spot Geolocation

The Angle of Arrival 100 antenna system is the inno-vation on the sector of direction finding. Working over an ultra wide frequency range of 8 kHz up to 12 GHz (dependent on the configuration), this antenna forms the most compact full band solution for monitoring and direction finding in one module. Using multiple high pre-cision antennas, the system can not only analyze the situation at one frequency but supports together with the unique DF Time Travel® a full band, all time direction finding, a feature which is uncontested in the market.

The AOA 100 has the unique capability to perform direction finding for both horizontally and vertical-ly polarized signals. In addition the integrated om-nidirectional antenna set enables monitoring from 8 kHz to 12 GHz. The AOA 100 consists of a ro-bust design able to cope with extreme weather and shock conditions, suitable for 24/7 operation at fixed sites or mobile applications when mounted on a vehicle.

Heatmap and Multi-Spot AoA

Are there more signal sources around on one channel? Hard to say with a standard DF cross section result. You are always only presented with the most likely result, while all other information is discarded. Multi-spot AoA,

based on a heatmap, allows the user to visualize the full picture. Identifying easily whether the most likely result may still be a reflection or if there is more than one sour-ce transmitting.

DF Time Travel® AOA

LS telcom introduces with the AOA 100 a brand new DF technology, called DF Time Travel® that allows custo-mers to perform DF not only live as usual but also in the past based on recorded DF / spectrum measurements, in order to track signals in the past, even when they are not currently transmitting.

Looking only once a day at the situation picture will tell you a quite different story from having a permanent tra-cking of all movements. It also allows you to identify signal source locations after interference cases have already disappeared. This is extremely useful as comp-laints usually appear some time after the incident!

Full Band AoA

Do you know which band segment may be of interest later-on? No problem with our innovative full-band AoA! The user selects only the band of interest, which may be one channel, 1 MHz or everything from 8 kHz to 12 GHz. The system will record and store the informa-tion for up to 30 days even for the full band*. It allows to look at what did happen in the past, not only at one channel or in the real-time bandwidth, but also in the complete DF band. The system allows, based on the stored data to carry out all of the analysis like DF Time Travel® AoA, heatmaps and multi-spot direction finding.
