En este artículo se presenta una revisión bibliográfica y un análisis comparativo de implementaciones en hardware de técnicas de Radiogoniometría, también conocidas como Radio Direction Finding (RDF), que permiten identificar la mejor opción para implementar estas funcionalidad en actividades de gestión del espectro en países en vía de desarrollo. Dentro de las implementaciones tratadas se incluyen técnicas clásicas como Pseudo-Doppler y técnicas avanzadas de alta resolución como MUSIC. Se presentan diferentes alternativas de hardware para realizar las implementaciones las cuales incluyen SDR (Software Defined Radio), FPGA (Field Programmable Gate Array) y DSP (Digital Signal Processor); a la vez que se incluyen algunas configuraciones híbridas dónde se mezcla el software y el hardware con el fin de optimizar recursos de tiempo y dinero. Adicionalmente se muestran algunas aplicaciones comerciales que emplean técnicas de geolocalización basadas en información de ángulos de llegada, tiempos de llegada u otros parámetros que permiten realizar el proceso de triangulación o trilateración según sea el caso.

Abstract— Flight Control System is an integrated avionics system equipped with the minimum required components for an autonomous flight. This paper focuses on the Hardware Design of the Flight Control System and presents specific details of the components and its interface. The system architecture is based on Field Programmable Gate Array and Digital Signal Processor. Employing these two processors in the flight control system would improve the Flight Control System performance in terms of fast sequential processing of high-level control algorithms. In addition to Field Programmable Gate Array and Digital Signal Processor, the flight control computer system will also make use of Global Positioning System and Micro Electro Mechanical System sensors. The project will be implemented using Altera’s System On Programmable Chip builder, currently known as Qsys – Platform Designer implemented in Quartus-II. The system employs Nios-II processor which is 32-bit soft-core embedded-processor architecture designed especially for the Altera’s family of Field Programmable Gate Array. From conceptualization to final design, this paper presents the functionality of the different modulus and complex interfaces employed in this Flight Control System.
