  • Galileo Satellite Metadata | European GNSS Service Centre
    The Galileo satellites metadata are information about the satellite properties which need to be known in order to properly implement advanced processing algorithms for precise orbit determination or Precise Point Positioning (PPP). These include physical characteristics such as mass, area or reflectivity, the attitude law and antenna parameters such as phase center offsets and variations. More information about PPP and GNSS data processing can be found in [3], [4] or [2]. For Galileo SIS details, please refer to [1].

  • LEA-6T GPS breakout board with Precision Timing - CSG Shop
    The uBlox LEA-6T supports precision GPS timing for demanding positioning applications such as basestations. It features a time mode function whereby the GPS receiver assumes a stationary 3D position, whether programmed manually or determined by an initial self-survey. Stationary operation enables GPS timing with only one visible satellite and eliminates timing errors which otherwise result in positioning errors. An accuracy of up to 15 ns is achievable by using the quantization error information to compensate the granularity of the time pulse. A built-in time mark and counter unit provide precise time measurement of external event inputs
