Rocketry has experienced a revolution in technology now available to the common hobbyist.
There are a variety of vendors that now provide electronic payload packages to record flight characteristics, altitude, speed, acceleration, and more.
Altimeters can (and usually do) include capabilities to control apogee and main parachute deployment events with black powder charges.
In addition, GPS and Radio tracking systems are also available.
