ATC radar for Fans

The delivery of the article of GNS5890 ADS-B receiver was fast and reliable. The product fully meets my expectations in technical terms as well as in the application. The product is worth the money.
I liked the GNS 5890 particularly like small design of the USB Dongle, the high sensitivity of the ADS-B receiver and the optimized and tuned to the frequency range antenna. The data reception is much better than RTL USB dongle solutions to a similar extent. Unpacking the CD, GNS 5890 infected the USB port, driver and software in Windows adsbscope install 7/8 infect antenna, make some adjustments in adsbscope, press Start and off you go. An update of adsbscope software you can download on the web page of GNS also. The beiligend descriptive manual is neat, for initial Ok, more information on the settings of the software so you can read on the supplied CD in PDF. The software is intuitive. You can also go an extra USB GPS receiver to infect his computer / laptop and fix their own location as in adsbscope. The GNS 5890 is also compatible with the Planeplotter software and can be operated with this. Excellent.
Under normal viewing conditions, between the houses, so you have a catchment area of ​​aircraft within a radius of 50km. From my experience with this receiver and a clear view, aircraft in a radius up to 250km sure traceable and visible in adsbscope if they have an altitude of 10-12km. Are between the airport and the own location houses or other obstacles, then the approaching / launching aircraft can be tracked in / from the runway only to the height of the line of sight to the aircraft's location. But that is clearly at a frequency of 1090MHz and is not a defect of the product. The propagation of electromagnetic waves are at this frequency other than the VHF range. Want I recommend this GNS 5890 ADS-B Receiver people who enjoy the aeronautical radio navigation, consider this as an additional resource, know which planes land near the own airport and start flying over which aircraft in 10-12km height the houses of the city. You should be familiar with the concepts of air navigation, the essence of this terminology is described in Wikipedia anyway or in forums on the Internet for their own entry.
