The “B” Code: Bearing or Azimuth<br />
Chapter 5 Preparing Input Data<br />
B From-To Bearing (or Azimuth) [Standard Error]<br />
Example 1:<br />
B tower-flagpole N34-23-45.7E !<br />
The bearing from “tower” to “flagpole” is N34-23-45.7E. The bearing will be fixed in<br />
the adjustment because of the “!” symbol. Bearings are distinguished from azimuths by<br />
the presence of an “N” or “S” at the beginning and “E” or “W” at the end.<br />
Example 2:<br />
B 5660-5661 243-43-46 20<br />
The azimuth from station “5660” to “5661” is 243-43-46 and it has an entered standard<br />
error of 20 seconds. This might, for example, represent data entered for an observed<br />
solar azimuth.<br />
Example 3:<br />
B 1022-1023 111-23-14.0<br />
The azimuth from “1022” to “1023” is 111-23-14.0. The standard error defaults to the<br />
standard error for bearings and azimuths as set in the Project Options.<br />
Example 4:<br />
B 51-52 150-33-44 *<br />
The azimuth from “51” to “52” is 150-33-44 but is set free using the “*” symbol. A<br />
“free” observation will not influence the results of an adjustment, however its residual<br />
(the difference between the entered and the adjusted observation) will be shown in the<br />
listing file.<br />
Setting a specific observation free is a technique often used when trying to isolate<br />
suspected blunders in a network adjustment.<br />
