    • A miniaturized two axis sun sensor for attitude control of nano-satellites 

      Angulo, M.; Gras, Ana; Ortega Villasclaras, Pablo Rafael; López Rodríguez, Gema; Ricart Campos, Jordi; Domínguez Pumar, Manuel; Castañer Muñoz, Luis María; Quero, J.M.; Tarrida, C. L.; Reina, M. (2010-10-10)
      Article
      Open Access
      This paper describes the design, fabrication, characterization, and satellite integration of a miniaturized two axis sun sensor which has been used in the attitude control system of the Spanish nano-satellite NANOSAT-1B. ...

    • A persistent scatterer interferometry procedure to monitor urban subsidence 

      Crosetto, Michele; Monserrat, Oriol; Barra, Anna; Cuevas-González, Maria; Krishnakumar, Vrinda; Mróz, Marek; Crippa, Bruno (2019)
      Conference report
      Open Access
      This paper describes a Persistent Scatterer Interferometry procedure for deformation monitoring. Its more original part concerns an approach to estimate the atmospheric phase component. The procedure can be used to monitor ...

    • Airborne ionospheric gradient monitoring for dual-frequency GBAS 

      Gerbeth, Daniel; Caamaño Albuerne, María; Circiu, Mihaela-Simona; Felux, Michael (Curran Associates, Inc., 2022)
      Conference report
      Open Access
      Certified Ground Based Augmentation Systems (GBAS) as of today operate using only GPS signals in the L1 frequency band to enable precision approach guidance for landing aircraft. Ionospheric activity (i.e., scintillations ...

    • DVB-T based Passive Radar for Aerial surveillance 

      Cardona Reverter, Claudia (Universitat Politècnica de Catalunya, 2018-02)
      Bachelor thesis
      Restricted access - confidentiality agreement

    • Low altitude rocket tracker based on monopulse radar 

      Mitjans, Joan (Universitat Politècnica de Catalunya, 2018-07)
      Bachelor thesis
      Open Access
      Tracking is one of the most critical subsystems in a sounding rocket, as safety, security and recovery of the payload are directly related with an accurate positioning of the spacecraft. There are some different techniques ...

    • Receiving and Processing ADS-B Signals for Aircraft Tracking 

      Wang, Xin (Universitat Politècnica de Catalunya, 2019-07-15)
      Bachelor thesis
      Open Access
      Automatic Dependent Surveillance-Broadcast (ADS_B) system is one of the most important innovation of radar system which is used for direct state information exchange between aircraft. The project consists of the study of ...

    • Spherical wave near-field imaging and radar cross-section measurement 

      Broquetas Ibars, Antoni; Palau, Josep; Jofre Roca, Lluís; Cardama Aznar, Ángel (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1998-05-31)
      Article
      Open Access
      The paper presents a new inverse synthetic aperture radar (ISAR) algorithm intended for radar cross-section (RCS) imaging and measurement from scattered fields. The method, based on a spherical-wave near-field illumination ...
