      Invisible shield found thousands of miles above Earth blocks 'killer electrons'
      A team led by the University of Colorado Boulder has discovered an invisible shield some 7,200 miles above Earth that blocks so-called "killer electrons," which whip around the planet at near-light speed and have been known to threaten astronauts, fry satellites and degrade space systems during intense solar storms.
      The barrier to the particle motion was discovered in the Van Allen radiation belts, two doughnut-shaped rings above Earth that are filled with high-energy electrons and protons, said Distinguished Professor Daniel Baker, director of CU-Boulder's Laboratory for Atmospheric and Space Physics (LASP). Held in place by Earth's magnetic field, the Van Allen radiation belts periodically swell and shrink in response to incoming energy disturbances from the sun.
      As the first significant discovery of the space age, the Van Allen radiation belts were detected in 1958 by Professor James Van Allen and his team at the University of Iowa and were found to be composed of an inner and outer belt extending up to 25,000 miles above Earth's surface. In 2013, Baker -- who received his doctorate under Van Allen -- led a team that used the twin Van Allen Probes launched by NASA in 2012 to discover a third, transient "storage ring" between the inner and outer Van Allen radiation belts that seems to come and go with the intensity of space weather.

    This explanation is the clearest and most thorough about the GPS system on youtube, thank you for making it. The information I'm trying to track down is 'the maximum theoretical limit of GPS refresh rate'. I initially assumed that the satellites sent pulses, but actually they seem to send a continuous bitstream. This makes me wonder why the fastest commercial GPS units calculate your position at 100Hz. I understand that there may be no point calculating at 1000Hz (because there aren't many things you need to track that frequently, and in that time the object won't have moved out of the 30cm circle position that is the max accuracy the system can give you), but I'd still love a further explanation of what the limits of GPS would be (with current broadcast frequencies) especially when it comes to how often you could obtain a meaningful new position update for a receiver.

    Very good and understandable presentation. I have been researching how the signals are generated by the GPS satellites for use in the reciever. I had no idea how much external input is required for error correction via ground control. It appears as though the system would become worthless in a few days if not constantly corrected. Very enlightening. Thank you.

  • @jaxontaylor9670
    @jaxontaylor9670 3 роки тому +3

    Excellent explanations. I learned a lot.
    The only bit that is unclear to me is how does the GPS receiver generate its own GPS signal to compare to the received signal? Does it just guess when it should create it? Does it get this timing info from the satellite?
    I understand the errors and how they are calculated, but for determining the initial pseudorange, I don't get how the receiver makes the signal "exactly" when the satellite does

    • @jayw.8626
      @jayw.8626 Рік тому

      "The GPS receiver uses a process called differential GPS, which compares the time from the GPS receiver’s clock to the time from a ground-based GPS reference station. By comparing the two times, the GPS receiver can calculate and correct any time errors."

    You mean it can t move without placing it on a very powerful airplane placed at its orbital with space rocket .wow I think your theory is interesting , you mean every satellite works on standard parameters that somewhere there is a communication between your four satellites placed on 22k kilometers or that each one of them provides a different signal intensity . That position is calculated through analysing some parameters and combining them .
