The pings are picked up by sensors that are laid along the pipe, and are linked to
a GPS time clock and an accelerometer that captures each rotation the ball makes.
Not exact matches
The higher frequencies mean that optical
clocks «tick» faster than microwave atomic
clocks and could thus provide
time - stamps that are 100 to 1,000
times more accurate, greatly improving the precision of
GPS.
By checking in constantly with whatever
GPS satellite is in view at a given
time, a pair of gravity satellites can use its single
clock rather than trying to synchronize their own.
Along with Mars 2020, STMD is hard at work, advancing promising technology for potential infusion into these Mars missions including: Heat - shield for Extreme Entry Environment, a tailorable, woven thermal protection system that would reduce entry loads and greatly reduce heat - shield mass; Deep Space Optical Communications, which will improve the data - return capacity from space to Earth by more than 10
times the current state - of - the - art; and the Deep Space Atomic
Clock project which will revolutionize deep space travel by improving the precision of space navigation and enabling more efficient use of tracking networks like
GPS.
A test last year in Washington, D.C., by the U.S. Naval Observatory, the division responsible for maintaining the
GPS master
clock, found that Locata's web of signals synced up within 200 trillionths of a second, more than 50
times faster than
GPS.
Chip - scale atomic
clocks keep
time well enough for many applications requiring
timing synchronization over short periods, such as
GPS receivers.
Anyway, your watch is fine for getting to work about on
time, but if you want your
GPS to work fine, you need these atomic
clocks on Earth and on satellites.

Adjust your paces, interval
times, and length of rests to efforts that feel right — or, better yet, scrap the
GPS and practice tuning into your body by running by effort rather than by the constraints of a
clock.
The heater control panel integrates the digital
clock and outside air temperature displays, with the
time automatically corrected by
GPS in navigation - equipped models.
The vehicle
clock is independently controlled by
GPS data, so when
time zones are crossed while driving, the
clock will automatically set itself to the current
time.
External

GPS, RTC and IRIG - B used for
clock drift management.
