Hey, don't say craps. I'm from the same country of Leonardo da Vinci, the father of airplane, helicopter and mechanical machines.
SECOND STATEMENT: NASA's buffoons say the probe passes near Venus and Venus increases its velocity. COMPLETELY FALSE.
Venus is not magic, it has no capacity to increase spacecraft's velocity.
Venus hasn't hands to give a push to the probe.

I ran the Bigpain part of this message through Babel fish, English to Italian and then back again.
Everything came bach exactly the same except Leonardo Da Vinci's name.
It came back: Leonardo YOU WIN (upper case included).
If this is a game, then I won, apparently.
But who is Leonardo? |

It's no use, folks. We'd have to teach bigbrain how to triangulate, and also that the same techniques apply whether using radio or visible light.
We don't even have to triangulate...
First we use radio-telescope to locate declination and rectacention, just as bigbrain suggested. But finding the distance between Earth and the probe is even simpler:
We send a radio signal with a control-message to the probe. The probe has been programmed to recognise the control-message and immediately send a response. Since the engineers building the probe knows exactly how many microseconds it takes for the probe to respond we can subtract that time from the response: we can measure the delay from when we sent the control message to when the answer is received. take off the probes internal delay, divide the time by 2 and use light speed to calculate the distance.
With a 3MHz clock resolution in the distance-transceiver equipment, and a 30ns accuracy of the probe-delay we can measure the distance to the probe with a margin of only 100 meters!
At the risk of being murdered by my own government (or US government) for revealing military secrets, this principal has been used in military aircrafts since the late 60s.

This is a very interesting phenomanon, and one worth exploring in another seperate thread, but it does appear on casual observation that the most frequented threads are the ones heavily involving charecters like Bigpain.
There's a lot of rubber-neckers around here. |

Seriously, the views-to-replies ratio is usually about 10:1. The difference with this thread is that bigbrain posts a lot of nonsense, and so it takes lots of replies to try to correct it. Plus, it's an easy dogpile. That's why the reply count got so high so fast (but views-to-replies is still about normal). |

And I find that even with my simulated Cassini going nearly 2,000 m/s faster than it should at the 50-minute mark, it only gets out to about 4.66x108 km (asteroid belt?) before turning back around towards the Sun (that's what I should have said in that other post, sts60: falling towards the Sun, not into). It gets that far after traveling for over 535 days, and nearly 180° around the Sun.
(Let's get a math check: at 3,317,000.0 m above the ground - which is itself 6,378.14 m from the center of my point mass of 5.976x1024 kg representing Earth - my model Cassini of 5,655 kg experiences a force due to Earth's gravity of 71,088.785 newtons. Everyone else get that number?) |

I find threads like this one to be cathartic. I work in the support dept. of a software company and have to deal with both dim and arrogant people, sometimes both, every single day. I enjoy witnessing one such get his comeuppance. It helps keep me sane.

Apollo used a similar method for ranging. From http://www.honeysucklecreek.net/station/technical.html
quote:
Ranging was a code transmitted to the spacecraft and returned for time comparison with the original code. The pseudo random noise range code, generated by a dedicated ranging system, was a combination of 5 codes to form a 5.4 second period code of 5,456,682 bits, which gave a maximum unambiguous range of 804,650 km, or twice the distance to the moon.
Ranging was initiated manually by the Ranging Technician after the station was locked onto the signal from the spacecraft, and once acquired by the code, was updated by doppler only. Resolution within the Ranging System was +/ 1 metre, but system jitter and ground instabilities gave an overall accuracy of +/ 15.2 metres.
The range code was summed with the other uplink signals and phase modulated onto the carrier.
There's a more detailed explanation on the 'net somewhere, but I can't seem to find it right now...

| Oh, yeah, I forgot to answer Mab! Yeah, ranging may be "simpler" for you and I to understand, but it depends on computer timing and whatnot, and I've got a feeling that the Internet is about all the computer-related stuff that bigbrain can handle. Triangulation can be done with a paper and pencil. |

Funny, Dave, because when I do the math, all I get is "blue three tesseract" which, in my estimation, just can't be right. But I'm no good at math... |

| Cune, stop trying to do the math in Sumerian. "Blue three tesseract" only needs to be translated back into English, et voila! 71,088.785 newtons. |

I've just had another thought.
What if Braindead is really a front for an al-Qaeda rocket building cell pumping for information?
All this information might just be helping them establish a new base of operation.
