Not be an omnidirectional antenna anymore. But if they are placed side by side, then the antenna would To improve the antennas sensitivity multiple electric dipoles can beĬombined. Such an antenna is an electric dipole and receives Wire or metal stick of 13 cm length, this is the half wavelength of A vertical polarized antenna tuned to 1090 MHz is This is used to draw the radar picture.įor all 4 functional blocks different solutions are available in the

The PC receives the ADS-B-data and extracts all interesting This data is forwarded to the PC via USB (or RS232). The decoder converts the analog video signal into a digital signals andĭetects inside the received signal-chaos the replies fromĪDS-B-transponders. The receiver selects, amplifies and demodulates the signal. The antenna received the electromagnetic wave, converts it into anĮlectric signals and feeds this through the coaxial cable into the

The receive antenna should be mounted at a high There is no disturbing object in the line of view between aircraft and Linear through the atmosphere and are not reflected by the upperĪtmospheric layers (ionosphere). Receive this transmissions one needs a receiver for this frequency - anġ090 MHz is a frequency inside the L-band. (Automatic Dependent Surveillance–Broadcast)Īll aircraft transponders transmit data at the frequency 1090 MHz. Why should somebody do this? Because it's fun. Thus the virtual radar gives you a good idea about the air

If the ground station employs a directional antenna and measures the In the aircraft answers by sending a replay back to the ground station. Interrogation to a special receiver inside the aircraft, a transmitter A ground station (interrogator) transmits an Large areas of the US-airspace are not covered by radar. Transponders of threes aircraft had been switched off. The book has 224 pages and includes over 150 illustrations and diagrams.Software with PIC18F2550 back to my projects, PIC-Microcontrollers, Electronic, Homepageĭo you remember the 11st September 2001 ? In the USA some aircraftĭisappeared from the screens of the air traffic controllers (ATC). PlanePlotter plots aircraft positions, altitudes and times decoded from the message traffic that it receives including embedded position reports, AMDAR reports and ADS reports contained in ACARS messages and ADS-B position reports received by a variety of virtual radar boxes including the Kinetic-Avionic's SBS1(tm), AirNav System's RadarBox(tm) and the PlaneGadget Radar Mode-S receivers. PlanePlotter provides a radar-like display of not only local aircraft but aircraft around the world that are transmitting the digital messages in the ACARS, ADS-B and HFDL formats.
