SNAP-1: Launched 2000

SNAP-1 mission objectives: 

• To provide a test-bed for novel micro-electronic technologies - in particular a new GPS navigation system, APS camera technologies and RISC processors.
• To provide experimental data and imagery to the radio-amateur/amateur scientific communities.
• To provide a vehicle for the education and training of students in spacecraft engineering at undergraduate and post-graduate level.  
• To demonstrate the feasibility of using clusters of low-cost satellites that can fly in formation and conduct multipoint remote sensing.

SNAP-1 mission achievements:

• The first fully 3-axis attitude stablised nanosatellite.                    
• The first nanosatellite with on-board propulsion demonstrating orbit control.
• The first in-orbit images of another spacecraft from a nanosatellite.
• The first successful use of GPS on-board a nanosatellite - used for orbit manoeuvring
• First use of propulsion on a nanosatellite and first use of butane as a space propellant

SNAP-1 imaging capabilities:

Three wide-angle CMOS cameras, each with a 350 x 288 pixel detector, and each with a 90 degree field of view to cover an arc of 270 degrees.

A single narrow-angle camera (350 x 288 pixels) co-aligned with the centre wide-angle camera providing the capability of finer feature inspection.
