7. Pulse-per-second (PPS) Signal Interfacing
Some radio clocks and related timekeeping gear have a pulse-per- second (PPS) signal that can be used to discipline the local clock oscillator to a high degree of precision, typically to the order less than 50 us in time and 0.1 PPM in frequency. ... Either way requires conversion of the PPS signal, usually at TTL levels, to RS232 levels, which can be done using a circuit such as described in the Gadget Box PPS Level Converter and CHU Modem page. ...

8. More on Kepler's Second Law
... Kepler's Laws . ... Second Law . 12a. More on 2nd Law . ... Kepler's 2nd law prescribes the way the velocity V of an object orbiting a single center varies around its orbit: . The rate at which the line to the center ("radius vector") covers area does not change around the orbit." As noted in section #12 , this means that the object's velocity V increases when its distance r decreases, and vice versa. ... Because by Kepler's 2nd law, the Earth moves in its orbit a little faster in winter. ...

9. Source Selection
... The stars examined here were primarily culled from two lists of X--ray sources in Orion. ... The second region is two degrees in extent east--west and ten degrees north--south with Orionis being near the northern edge. ... In the end, two main regions were chosen for monitoring: stars near Orionis and stars northwest of the belt of Orion. ... The PSPC identified 22 sources within 15 of Orionis in addition to the sources listed in Table 1 , giving a total of 85 X--ray sources in the Orionis region. ...

12. The International Space Station becomes the second brightest object in the
... Armagh Observatory, 24th March 2009: The International Space Station ( ISS ) has recently become the second brightest object in the night sky тАФ even brighter than the planet Venus, and second only to the Moon. Evenings will provide the chance of a spectacular view, if the sky is clear, as for the next few days the orbit of the ISS around the Earth repeatedly takes it over Ireland. ... At its best, it is now the second brightest object in the night sky. ...

... The first time you acquire an object you must include the overhead for the guide star acquisition. ... If it is larger, then the observer can choose to maintain pointing through the gyros (drop-to-gyro) or re-acquire the guide stars (3 minute overhead per re-acquisition-note that this is not the 6-minute orbit re-acquisition) every time the telescope goes back to the target; with the first option the pointing uncertainty is about 1 milliarcsec/second due to telescope drift. ... Exposure overheads: ....
