STRaND-1 is the first in a series of Surrey Satellite Technology Ltd. (SSTL)-Surrey Space Centre (SSC) collaborative satellites designed for the purpose of technology path finding for future commercial operations. It is the first time Surrey has entered the CubeSat field and differs from most CubeSats in that it will fly a modern Commercial Off The Shelf (COTS) Android smartphone as a payload, along with a suite of advanced technologies developed by the University of Surrey, and a payload from the University of Stellenbosch in South Africa. STRaND- 1 is also different in that anyone (not just from the space engineering or space science community) will be eligible to fly their “app" in space, for free. STRaND-1 is currently being manufactured and tested by volunteers in their own free time, and will be ready for an intended launch in the first quarter of 2012. This paper outlines the STRaND pathfinder programme philosophy which challenges some conventional space engineering practises, and describes the impact of those changes on the satellite development lifecycle. The paper then briefly describes the intent behind the design of STRaND-1, before presenting details on the design of the nanosatellite, focussing of the details of the innovative new technologies. These technologies include two different propulsion systems, an 802.11g WiFi experiment, a new VHF/UHF transceiver unit and a miniature 3-axis reaction wheel assembly. The novel processing setup (which includes the smartphone) is discussed in some detail, particularly the potential for outreach via the open source nature of Google's Android operating system. A stepthrough of the planned concept of operations is provided, which includes a possible rendezvous and inspection objective, demonstrating equal or improved capability compared to SNAP-1 with a reduced total system mass. Finally, data from the test campaign is presented and compared against other notable CubeSats known for their advanced capabilities. Rendered images of STRaND-1 are shown in Fig. I and are discussed later in the paper.
