atomic clock radio Can anyone guarantee two atomic clocks are perfectly synchronized when measuring light & radio sygnal delays?
In relativistic physics, radio signals and light bend due to interactions with plasma (for example, when they cross the vicinity of the Sun). But how can anyone guarantee that two atomic clocks, placed in distant locations, used for measuring time delays caused by geometrical differences between the extremities of bent trayectories, are synchronized with each other accurately enough?
They're not bent dues to interaction with plasma, they are bent due to the gravitational effect of SO MUCH plasma.
The only way to assure it is to know exactly how long it takes a signal to get to the other clock and back, then when you query it as to it's exact time, you can subtract that time from any difference that shows up.

The new Casio G-Shock RISEMAN, released by Casio America is the world’s first watch to feature the Multi-Band 6 Atomic Timekeeping Technology. Along with solar-powered technology, the Multi-Band 6 Atomic Timekeeping feature enables the watch to receive time calibration radio signals from six transmitters worldwide — one in the US, two in Japan, and one each in China, Germany and the UK. For superior display accuracy, the signals are received up to six times a day. Inspired by those who challenge high altitudes, the RISEMAN features twin sensors for both pressure and temperature in a shock-resistant case. This new G-SHOCK watch is equipped to measure altitude, barometric pressure as well as air temperature. Also, the RISEMAN features a full range of measurement functions, and boasts a unique three-layer protection structure to protect and enclose the pressure sensor. “The RISEMAN is a perfect example of Casio G-SHOCK’s commitment to both function and technology,”. “Casio G-Shock has been and always will be consummate innovators. We are pleased to be the first to introduce the Multi-Band 6 Atomic Timekeeping technology to the marketplace.” Always on the cutting edge, Casio has improved the sensor-based measurement system. The RISEMAN’s altimeter can record measurements using both the stopwatch and the altimeter simultaneously. This versatile feature can capture recorded time along with changes in altitude, elapsed time, total ascent and descent altitude, and highest and lowest altitude. Capable of measuring altitude at five-second intervals, the watch is able to handle altitude changes over very short intervals of time, a useful function for sports enthusiasts involved in rock climbing, mountain biking, and back country skiing. With the mountain-based athletes in mind, the RISEMAN possesses a smooth back to reduce the gap between the watch and the wrist for a comfortable fit, while the band configuration prevents sweat from gathering. Additionally, the dragon has been chosen as the RISEMAN’s back emblem for its mythical ability to fly by manipulating the weather. Construction: Shock resistance Water resistance: 200 meters Radio frequencies: WWVB (USA): 60 kHz, JJY (Japan): 40 kHz (Fukushima) / 60 kHz (Kyushu), MSF (UK): 60 kHz, DCF77 (Germany): 77.5kHz, BPC (China): 68.5kHz Radio wave reception: Automatic reception (maximum 6 times per day) and manual reception options Barometer: Display range: 260hPa - 1,100hPa (7.65 to 32.45 inHg), atmospheric pressure tendency graph (past 24 hours graph display), atmospheric pressure differential graphic (arrows displaying the latest trends in atmospheric pressure) Altimeter: Display range: -700m – 10,000m (-2,300 to 32,800 ft.), cumulative altitude memory (memory works together with the stopwatch to record elapsed time, cumulative ascent and descent altitudes, highest and lowest altitude recorded); manual altitude memory (up to a maximum of 20 memory sets, with each set recording the altitud

Nice job, but wouldn’t it have been cheaper, easier, and more practical/accurate to sync up with an atomic clock? I seem to recall HaD running a simple project that used one of the atomic clock radios; the module only cost something like $10 and was exceptionally easy to interface with.Bonus points for style using GPS, but certainly a downside to this build is that it won’t work unless near a window with a clear view of the sky.
Indeed, Al. That’s why I said how not to do tech support. The point I made in the article is that a lot of technology is simply too obtusely constructed for ordinary people to grasp, and looking down on ordinary people for not being able to do things they consider “easy” is a common geek failing.

Hi, JT here. I recently received a Projection Alarm Clock as a gift and thought that it was just the coolest thing ever. I've started giving them to friends and thought I'd do a little research and put a site together about Projection Clocks and Atomic Clocks. I hope you enjoy!
