    You keep repeating this post -- you're not supposed to post the same thing over and over and over.
    .
    ESPECIALLY when it contains grammatical errors -- that is, unless you want to be known as a dunce.
    .
    NASA claim there are thousands of satellites orbiting the earth; it should be very easy for Neil Obstat to find a picture of a group of satellites in space.
    .
    As I explained before, NASA is a second person singular number proper noun (like he, she, it) but the verb you're using with it, "claim," is a second person plural number verb (like for they). Examples:  NASA claims; two or more organizations claim; I claim; you claim; he / she / it claims; we claim, they claim.
    .
    Since you seem to enjoy repeating yourself, and have resorted to not reading the thread which has already answered your unreasonable demand, perhaps it would be of some small interest to you to read the following post which you must have missed previously since you have not made any reply to it nor has anything you've posted since reflected some small clue that you understand what St Ignatius is saying here:
    .
    Watch out! Trick question... we ALL know satellites don't fly in groups...
    .
    Did you read that? Satellites don't fly in groups. Do you know what that means?
    .
    How do you expect to find a photograph of something that cannot be photographed?
    .
    Can you remain standing in the parking lot of a supermarket and from there take a photograph of a can of soup, a bottle of wine and a bushel of apples that are located at different places inside the store?
    .
    Can you photograph all the planets of our solar system in a group?
    .
    Can you take a picture of one person in Las Vegas, another in New York and a third in Paris, France, all at the same time? Most satellites in space are much further apart than that.

    Moving right along...........
    .
    .
    .
    2. Unit description and objectives

    In this unit you will learn how the signals transmitted by GNSS satellites are used to obtain an approximate distance (pseudorange) from a point on Earth to each satellite. After completing this unit you should be able to:


    • 1.  Explain how the receiver determines the identity and location of each satellite using the navigation message and signal-matching.

    • 2.  Explain the process for estimating pseudorange using PRN code synchronization.

    • 3.  Describe how estimated position is calculated using pseudoranges.

    .

    That is, you should have acquired the skill set = {1, 2, 3}, unless you are a flat-earther, in which case you'll no doubt post such non-sequiturs as thisthis, or this, which see.  You can't make this stuff up!!
    .
    Sometimes being uneducated evokes frustration, I know, but if you put forth a little effort and become informed you'll find the frustration abates in spades which can be a great feeling. 
    .
    It is my sincere hope that readers will experience this liberating relief of the frustration they may have felt when using GPS in the past and having NO IDEA what is going on in this "black box" gadget that ominously always seems to know more about the user than the user knows about himself.

    Really? Gee, how did you manage to derive that warped non-sequitur?

    Are non-sequiturs your specialty?

    I'm not complaining, actually, it's really nice to see you spell one sentence correctly.  ;)

    Are you saying that a can of soup, a bushel of apples and a bottle of wine don't exist in a supermarket?

    Maybe not in Puerto Rico today, but that's another problem.

    Truth is Transitory has shown he is able to read a few words, unfortunately, he only reads words out of context.
    .
    Here are some words IN CONTEXT that perhaps you can understand, but probably not.
    .
    The predicted orbital parameters for a given satellite are recorded in a docuмent called an “ephemeris” (plural, “ephemerides”).
    .
    Did that register this time?
    .
    What is an ephemeris? What is meant by ephemerides? How are these words pronounced? From which language are they derived? Why do you suppose the plural is appended with "des" and the singular with "s?"

    The only reason Neil Obstat believes satellites can't be photographed is, because, Neil Obstat knows satellites don't exist.

    My gosh, now you're making stuff up. Is that what I said, or is it what you said about me?
    .
    Here is what I actually said:
    .
    Can you remain standing in the parking lot of a supermarket and from there take a photograph of a can of soup, a bottle of wine and a bushel of apples that are located at different places inside the store?

    .
    By that you have extracted that I said a can of soup, a bottle of wine and a bushel of apples don't exist in a supermarket, and the planets of our solar system do not exist and there is no person in Las Vegas, another in New York and a third in Paris, France at the same time.
    .
    Is that the extent of your reading comprehension?

    A group of satellites all together in space would be a group of them malfunctioning and in great danger of crashing into each other. Is that what you're hoping to see?

    Where in this thread did you read the following, because there is where you would have seen several satellites in space all at the same time, called "a constellation" :

    If you really believe satellites exist, post a picture showing several satellites in the picture frame. They don't have to be in a close group.

  • WHAT A TOTAL LIE!
    The horizon controls transmission and the power of the signal.
    .
    .
    .
    THE. END.
    .
    Actually, it is true that "If the earth were 'flat' all these transmission problems would be non-existent."
    .
    You have no proof of your "horizon" controlling transmission and the power of the signal.
    .
    You're just making stuff up, as usual.
    .
    Any ham radio operator knows he can perpetuate his signal even all around the world, showing that the earth is spherical, by his radio waves directed to bounce off the ground and off the ionosphere repeatedly, under the right conditions. This would not be the case with a "flat" earth because the waves would go off the "edge" of the so-called flat earth and be lost.

    .
    I can do as you ask, but I can only do it if you promise not to accuse me of posting CGI.
    .
    In fact, you already made this offer. Are you a man of your word, or are you a liar and a cheat?
    .
    Will you post a picture of a group of satellites in space if I promise not to say it's CGI?
    .
    Like I have said several times and you have ignored it, I have already given you what you ask for but you have not read the posts I make so you haven't seen what I posted.
    .
    When I asked you how you expect me to find a photograph of something that cannot be photographed, I gave you three examples of things that exist but cannot be photographed. Do you understand? 

    Or are you immune from understanding anything?
