[BA-Rockets] altitude tracking at DeAnza

[Gregory Wong]

Occasionally at the BayNAR launches at DeAnza College, I've noticed some
kids measuring the altitude of their rockets using those devices used to
measure angles.  (Sorry, can't think of the technical term.)  I also
noticed some kids are just too close to get an accurate reading.
Ideally, you should have 2 tracking stations to account for non-vertical
flight.  Of course, you need an accurate distance between the tracking
stations and the launch pad.

I'd like propose something and see what other BayNAR members think
of this idea.  One of these days, I'll measure some distances out
from the launch pad area.  I'll then place a barely perceptable mark
on the ground or make a note of a nearby landmark.  We're pretty
consistent with where the pad is set up.  When the kids come to track
the altitude, we can point out the spot(s) where they should set up their
tracking station(s) and tell them how far away it is.

What do you all think of this idea?  Has someone already done this?
