In the case of memory failure, the78IS-GPS-200F21 Sep 2011SV will transmit alternating ones and zeros in word 3-10 as specified in the above paragraph. The EAROMretentivity for Block IIA SVs is designed and guaranteed for at least 60 days.The memory retentivity is guaranteed for at least 60 days for SVs subsequent to Block IIA.Although the data content of the SVs will be temporarily reduced during the upload process, the transmission ofvalid NAV data will be continuous. The data capacity of specific operational SVs may be reduced to accommodatepartial memory failures.DIRECTION OF DATA FLOW FROM SV150 BITSWORD 1MSB FIRST3 SECONDSWORD 2WORD 3WORD 4WORD 571SUBFRAMENO.PAGENO.1N/A131TLM22 BITS61HOWC P73 77 8391121WNt22 BITSP23 BITS***P10BITSC/A OR P ON L2 - 2 BITSURA INDEX - 4 BITSSV HEALTH - 6 BITSP2 MSBs150 BITSIODC - 10 BITS TOTAL1N/A18124 BITS***P16BITS***WORD 8197WORD 9211 219T GDMSB FIRST3 SECONDSWORD 7151PL2 P DATA FLAG - 1 BITDIRECTION OF DATA FLOW FROM SVWORD 624 BITS***P8 BITSWORD 10241t oc16 BITSPa f28BITS8 LSBs271af116 BITSa f0PtP22 BITSIODC - 10 BITS TOTAL*** RESERVEDP = 6 PARITY BITSt = 2 NONINFORMATION BEARING BITS USED FOR PARITY COMPUTATION (SEE PARAGRAPH 20.3.5)C = TLM BITS 23 AND 24.
