This 24-slot arrangement … Webb31 maj 2024 · To implement this idea of using the hydrogen maser network to estimate GPS satellite clock biases, we have developed an algorithm with two steps. The first step is to compute the time difference between each satellite clock and each receiver clock, using code and phase measurements, respectively.
Webb10 juli 2024 · The satellites operate in Medium Earth Orbit (MEO) and continuously transmit signals to GPS units on the ground. Each satellite orbits the Earth twice a day and is equipped with atomic clocks, which are essential for providing accurate timing and positioning information. http://acc.igs.org/UsingIGSProductsVer21.pdf
