Student Rocket Program
Each year, NAROM arranges student rocket programs, where students get a first hand experience of how to build and launch a rocket reaching an altitude of approximately 9 km. The program is held at Andøya rocket range (ARS), which is a facility used by rocket scientists studying atmospheric events such as northern lights, noctilucent clouds and polar stratospheric clouds. Side by side with NAROM- and ARS-personnel, the students will build the payload with different types of sensors, do trajectory calculations, operate antennas and do necessary testing of the rocket. On launch day, the students will operate the different stations, such as the telemetry stations with the antennas, launch area and control tower.

Meaurements
The
payload contains sensors, an encoder, a transmitter and antennas. The
students have to manufacture eight different sensors measuring
acceleration, pressure, temperature, battery voltage, magnetic field
and light intensity, and integrate them into the payload. These
sensors must be made small and robust so that they can withstand the
extreme g-forces the rocket engine introduce them for.
The
encoder makes the analog values from the sensors into a digital
stream of bits, and passes it on to the transmitter. The transmitter
sends the measurements as a frequency modulated (FM) radio signal on
2279.5 MHz, which is downloaded through antennas located at the
rocket range.
Technical information
The rocket used in the student rocket
program is an old air-to-ground
missile, where the warhead is, off course, replaced by a payload
doing measurements. The rocket engine gives a maximum thrust of 6900
N, which gives the student rocket an acceleration of over 70 G.
