  1. 11. Test setup for LDMX HCal readout

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Joshua Greaves; [2020]
    Keywords : Dark matter; LDMX; dark photon; hadronic calorimeter; photomultiplier tube; Physics and Astronomy;

    Abstract : It is evident from cosmological observations such as the Cosmic Microwave Background, and the motion of galaxies, that the universe consists of approximately 5 times more mass than visible matter can account for. The Light Dark Matter eXperiment (LDMX) will take a unique approach in its hunt for dark matter; it will look for missing momentum signals in electron collisions with a Tungsten target, and will be looking in the sub GeV energy range for evidence of dark matter interactions.

  3. 12. Time Synchronization of TDOA Sensors Using a Local Reference Signal

    University essay from Linköpings universitet/Kommunikationssystem

    Author : Alfred Hult; [2020]
    Keywords : TDOA; synchronization; sensor network; correlation; time-delay estimation; estimation; UAV; GPS; timing signal;

    Abstract : Synchronization of distributed time difference of arrival (TDOA) sensor networks can be performed using reference signals from GPS satellites. This method provides high accuracy, but is vulnerable to jamming, and is not reliable enough to be used in military applications. READ MORE

  4. 13. Verification of Third Party Components to The Road Telematics Communicator

    University essay from Blekinge Tekniska Högskola

    Author : Shanmukha Raju Mantena; [2020]
    Keywords : Telematics; Global positioning system; Vector signal generator; Signal analyzer; RF Communication; Signal processing; Quality assurance;

    Abstract : The Road Telematics Communicator (RTC) as it is called in Scania. It is the device responsible to keep the vehicle connected and send the vehicle data to the off-board system. It uses data from different sources such as GNSS signals, CAN signal, and wireless Telecom signals. READ MORE

  5. 14. Robot Localization with Radio Frequency Identification and Time Difference of Arrival

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Håkan Göransson; [2020]
    Keywords : ;

    Abstract : In today’s robot technology it is important to have a system that enables fora robot to find its own position. This can be achieved with different kinds ofsensors, such as LIDAR, GPS and cameras, and sensor fusion. READ MORE

  6. 15. Ground Based Attitude Determination Using a SWIR Star Tracker

    University essay from Linköpings universitet/Reglerteknik

    Author : Karl Gudmundson; [2019]
    Keywords : Star Tracking; Celestial Navigation; Navigation Systems; Attitude; Orientation; SWIR; MEKF;

    Abstract : This work investigates the possibility of obtaining attitude estimates by capturing images of stars using a SWIR camera. Today, many autonomous systems rely on the measurements from a GPS to obtain accurate position and attitude estimates. READ MORE
