The Most Significant Bit is the first bit on the left of the binary word and will decide the sign of the varia-
ble. Below is a formula that you can apply to obtain the decimal value of the Roll using the above binary
word:
Where the binary word is:
Using this formula in this example, we obtain:
Scale Factor (see Table 48) = 0.01 degree
Thus,
The same method can be used for all PDx binary formats.
If you simply need to decode parts or all the data from each ensemble of your deployment PD0
data file into an ASCII file for post-processing, use
Decimal Roll = [(-1)x X x 2^ ) + (decimal(YYY YYYY YYYY YYYY)) ] x Scale factor
15
XYYY YYYY YYYY YYYY
Y.....Y = 111 1111 1110 1010
Decimal Roll = [(-1) x 1 x 2^ + (decimal (111 1111 1110 1010))] x 0.01deg
15
Decimal Roll = [-32768 + 32746] x 0.01deg
Decimal Roll = -0.22 degrees
