WebGPS receivers are made to receive 10.23 MHz code. But GPS satellites must broadcast this code on the frequency 10.22999999543 MHz to cancel relativistic effects. The effect (a time difference about 38 μs/day) is apparently insignificant, but it must be taken into account or there would be a 11.5 km/day position measurement error. WebNov 8, 2013 · The effect basically means that the onboard GPS clock runs fast or slow relative to a clock on the geoid (Earth's equipotential surface). A stationary GPS receiver located on the equator will...
WebThe weakness of gravity makes the clocks in the satellites appear to run faster than the clocks on earth by about 45 microseconds a day. Therefore, on balance, the clocks in the GPS satellites in space appear to run faster … WebFeb 1, 2024 · That effect adds microseconds to each day on a GPS atomic clock, so in the end engineers subtract 7 microseconds and add 45 more back on. GPS clocks don't tick over to the next day until they...
Webother external clock errors. Consequently, time determined by satellite clocks vary by from GPS time (by up to 1 millisecond). Simply adjusting satellite clocks to reflect GPS time would greatly diminish the life-span of the atomic clock. We will touch upon alternative solutions to this time adjustment later. 5.1.1 Relativistic Effects WebIf the calculation was done at the equator where the surface moves at 465 m/s and GPS satellites cross at 55 degrees, the SR time dilation works out to 6300 ns. That’s a 900 ns difference between pole and equator which presumably would yield an increasingly inaccurate position determination of 270 meters per day.
