•
Do a string manipulation and extract array s[i], a set of 3 positions coordinates from
each string 1
•
Convert the array of position strings s to array of position integers f and Assign
n1, n2, n3 to each of the position integer values f
for (i=0 → i=3)
string s[i]
→
f[i]
n1=f[1], n2=f[2] & n3=f [3]
Figure 6.13 (a) Output results from Sapphire HUB, (b) pseudo code to extract UWB position
coordinates
position information and elevation to the receiver. With the addition of a second
transmitter of known location and orientation, users can calculate the position of
the receiver in the base coordinate system. By adding two more transmitters,
the system can have four laser transmitters, so having its accuracy maximized.
