A PhoneSat-1.0 satellite, Graham was built to the single-unit (1U) CubeSat specification, and measures 10 centimetres (3.9 in) in each dimension.

The satellite is based on an off-the-shelf HTC Nexus One smartphone which serves in place of an onboard computer and avionics system.

The two other PhoneSat spacecraft launched aboard the same rocket were named Alexander and Bell.
