Signal Strength satellite name?

    When I do a SS on my HR22, I see the satellites as:


    But I don't see this nomenclature anywhere else (here in the forums). In particular I was looking at the transponder map found here: http://www.dbstalk.com/showthread.php?t=172247 (pinned above in this forum)

    I can map the satellites in the TPN to the names found in the network list (same thread as above), but I don't know how to tell which 99 is directv11 and which is spaceway2. Same for 103 with spaceway1 and directv10.

    The 110 and 119 seem easy enough, but from the conus beam network numbers (in the network list) does this mean 101 has three satellites (D4S, D8, D9S)? I'm just curious as to why 3 names for 101WL.

    Thanks in advance,

    I believe the major difference is that one of the sats at each location is used for spot beams. For 99 and 103 I think the spaceways are spot beams.

    And since 101 is the oldest, they probably needed to activate one for backup TPs.

    99(c) is DIRECTV11. 103(c) is DIRECTV10.

    There are indeed 3 sats at 101.

    D4S is the oldest one and just provides spot beams for locals. D8 provides all the even tps if memory serves and d9s provides all the odds and some additional spots.

    D8 and D9 also provide spots for back hauling using the KA band at 101.

    The different screens on the signal strength don't necessarily correspond to a single sat. For example both 99s and 103s have Tps that are spot beams from both a spaceway sat and d10 or d11.

    (s) = spot beams
    (c) = conus beam

    It all make so much sense! :D

    Your answers for this set of questions are all on the "Network Decoder" document (available at the link you provided below.)

    Let me try to help explain:

    Let's take the 99 location:
    In column 3 (Location/Beam) at line 4, you have 99, conus beams, 99c or 99a. Depending on your receiver, these conus beams are labeled either 99c (newer models) or 99a. It indicates that your conus signals are provided by D11 (column 2). Off to the right, (column 4) your signals are provided on TPN's 1 through 14.

    Go up to column 3 line 3. Here you have 99, spot beams, 99s or 99b. Depending on your receiver, these spot beams are labeled either 99s (newer models) or 99b. It indicates (in column 4) that your LIL (spot) signals are provided by SW2 (for TPN's 1 through 6) and D11 (for TPN's 14 through 24). Pay attention to the colors: on this line, red is SW2, blue is D11 .

    For the 101 location:
    Go to line 5: column 2 tells you there are three sats at this location. Column 3 tells you the red TPN's are spot beams, the white TPN's are conus beams. For the 101 sats, we don't know (and really don't care) which sats provide which specific TPN's.
    Hopefully, the rest of the chart will make sense now. The information for D12 is tentative at this time, we'll be smarter when it goes into service.

    If you still have question, please ask!!

    Thank you very much for pointing out what I missed, and taking the time to explain it.

    I certainly do appreciate the time everyone took to bring me up to speed!

    It may not be in the guide data stream but we do know which sats provide which tps.

    It looks like my memory was backwards. D8 provides all the odd tps, D9S provides all the even conus tps and shares the spots with D4S. Or at least that was the intent based on the design specs.

    Here's an updated version of the "Network Decoder". No data has been changed from the previous formats. But ...

    ..the presentation has been changed to use more color keying to try to tie the relationships together.

    ..the evan_s comments about the 101 TPN assignments has been incorporated

    If I have taken the confusing and made it yet more confusing, please let me know.


    2/23/10 Update:
    Please see this link here for the most current Network_Decoder document.

    That's great and the color coding is very good too.

    Up until this point, based on how the info was displayed on the SS screens, I thought 99/103(s) and 99/103(c) were nomenclature for the satellites, now I understand it to be conus or spot for the satellites at that position, but it does seem that a satellite can provide either. Very cool!

    The color coding of the TPNs correlates nicely to my own SS chart.

    Again, many thanks.
