SATELLITE TRANSPONDER LIST MANUAL
SATELLITE TRANSPONDER LIST SOFTWARE

For the spot beams on the Ku satellites on 101 and 119, all transponders on the same downlink frequency and polarity have the same TID and TPN (TPN=TID+1), and must use the same modulation, encoding and FEC for all transponders on that TPN number.ĭirecTV Band Plans, Frequencies, TIDs and TPNs All transponders with the same TPN number, on a given satellite, use the same downlink frequency and polarity. The two alternate uplinks, and three downlink beams are noted for each transponder.įor the Ka band and Reverse Ku band satellites at 99 and 103 West, each transponder has its own TID, and the individual digital streams can have different modulation, encoding and FEC parameters. Each of these groups of 6 represent only one transponder in the satellite that has two alternate input beams and 3 output beams. To satisfy FCC filing requirements, DirecTV documented 6 transponders for each uplink frequency. Each transponder processes one digital stream carrying multiple digitally modulated channels. There may be multiple amplifiers and filters on the input, it may be able to select alternate input beams, and it can feed multiple filters and TWTAs to feed the output beams. Note that in these tables, the concept of a “transponder” is the device that takes in one digital input stream, converts its frequency and transmits it on one or more output beams. Some of the data and beams for D10 and D11 are inferred from the detailed filings for D12. Those transponders, on the other hand, are used on D11. There are 13 spot beam transponders that share the same uplinks as another transponder, but are not used on D12. It does contain information on transponders that are only used on D11. It was built as a spare for both D10 and D11. The transponder map for satellites D12 and later are well documented in the FCC database. The data will be updated when there are any changes detected in the weekly data. On each sheet, the data is color coded to indicate its source, according to the key at the bottom of each sheet.

The FCC data is supplemented by the weekly data collected by our team, and manual entries created by analyzing the Beam Footprint Maps.Īll of the DirecTV satellites’ data are presented as an Excel workbook, with tabs for each satellite.

The TID and TPN used by the receiver software is shown and corresponds to the same values in Gary Toma’s TPN map, and the beam designations here are used to populate the beams identified in the weekly TPN map. They are based primarily on the Schedule S filings (or their earlier equivalents) that DirecTV filed with the FCC, documenting the frequency and uplink facilities for each satellite transponder, the output frequency of each transponder and the beam or beams that the transponder transmits on. Where Gary’s TPN Maps detail the data for each broadcast channel on DirecTV, these spreadsheets document the multichannel digital streams that carry those signals. The attached Satellite Transponder Tables are a complement to Gary Toma’s TPN maps. Domestic Satellite Transponders 220519.xlsx
