Abstract: Communication satellite downlink transmitting and reception techniques includes circuitry which groups a predetermined number of data cells with a predetermined error correction code to generate frame bodies. The circuitry also groups the frame bodies with header symbols and trailer symbols to generate data frames. One or more modulators enable the placement of the modulated data frames into a plurality of frequency bands having a predetermined frequency range and a predetermined transmission rate. One or more antennas transmit the modulated data frames over one or more beams with different forms of polarization to other antennas. A demodulator is connected to demodulate the radio carrier signals and the beams into data frames from a plurality of frequency bands. Decoders are connected to decode the frame bodies with header symbols and with trailer symbols from the data frames and to decode four data cells as a group by using a predetermined error correction code.

Abstract: Uplink transmission and reception techniques for a processing satellite including one or more earth terminals 400 connected to receive ATM data cells. One or more encoders 418 are connected to coordinate four data cells with an error correction code to generate data bursts and to coordinate the data bursts with synchronizing bursts to generate data frames. One or more modulators 420 are connected to modulate the data frames by frequency division multiple access modulation to enable placement of the modulated data frames into a plurality of channels. One or more antennas 406 transmit the modulated data frames to a satellite 100 over 48 beams with various forms of polarization. In satellite 100, a receiving multibeam antenna and feed 106 responds to one or more beams of radiocarrier signals having one or more forms of polarization. One or more demodulators 138 demodulate the radio carrier signals into data frames from various channels including a plurality of channel types. One or more decoders 146 decode data bursts and synchronizing bursts from the data frames and decode four data cells from the bursts using error correction code.

Abstract: Information is transmitted in an uplink to a satellite by applying an outer code to an information block to form an outer coded block. The outer coded block is then inner coded when a short block code is applied, thereby producing a concatenated coded block.

Abstract translation: 通过将外部代码应用于信息块来将信息在上行链路中发送到卫星以形成外部编码块。 然后，当应用短块码时，外部编码块被内部编码，从而产生级联的编码块。

Abstract: Measuring apparatus for determining the position of a point in a measuring volume relative to a datum point at which three mutually perpendicular axes intersect, includes a probe member supported for movement within that volume. Errors due to rotations about the various axes are corrected by providing additional transducers on each axis, there being (n+1) transducers where n is the number of rotations for which correction is required. The embodiments described have three X-axis transducers X.sub.1, X.sub.2 and X.sub.3 and three Y-axis transducers Y.sub.1, Y.sub.2 and Y.sub.3 which, with the appropriate circuitry correct for pitch and yaw errors about the two axes. For the Z-axis only two transducers, Z.sub.1 and Z.sub.2, are required. The circuit means combines the various transducer outputs to derive corrected values of the three co-ordinates.
