SAPPHIRE (Stanford AudioPhonic PHotographic IR Experiment, also called Navy-OSCAR 45) was a satellite built by the Stanford University students in Palo Alto, California.^[1]

The satellite was launched on September 30, 2001 together with Starshine 3, PICOSat and PCSat on an Athena 1 rocket at the Kodiak Launch Complex, Alaska, United States.

Its purpose was the training of students, the operation of an infrared sensor, a digital camera, a speech synthesizer and from 2002 the operation of an APRS digipeater.^[2] He also served to train midshipmen of the US Naval Academy in the field of satellite control.

The satellite's mission ended in early 2005.
