Angle Averaging

Last Updated 06/14/00

For users who wish to quickly compute the results of a direct/reverse set of angles we have written the following user program. This will work with Student Cogo, SiteStake, or Party Chief. It can easily be loaded as a user program (only Student Cogo 1.0 does not support user programs - check updates for information on updating to 1.1).

This program takes 4 angles on the stack as input:

Backsite Direct
Foresite Direct
Foresite Reverse
Backsite Reverse

From this data it returns:

Angle 1 (Direct)
Angle 2 (Reverse)
Difference
Average

All input and output is in DMS.

Follow the procedure in your manual for downloading user programs to the HP48. The program name is AVGANGLE.

Notes: This program will not compute the average properly in a case such as Angle1=359.5955 and Angle2=0.0005. In this case the mathematical average is 180 but intuitively we know the answer should be 0. This correction becomes too complex for such a simple program.
