ANDE LICENSING: ANDE is Licensed for operations in the Amateur Satellite Service
LITHIUM PRIMARY BATTERY POWER SYSTEM: ANDE runs on 112 "D" cell Lithium thionylchloride cells
arranged in 4 packs of 7 strings of 4 cells in series. For higher resolution photos than these,
see batteries in box
and battery box on disk
Battery Box Preliminary design sketches:

Battery Board PCB layout
Battery Life Management
uses 2 battery systems separately to yield measurable life data.
Present design yields 1.5 year Power Budget. The
lithium discharge profile is very flat to end of life.

WIRING HARNESS AND CABLING: The cabling and wiring design is 98% complete. Only the
following issues remain to be resolved: Exact connector for GSE, and exact connector for
Laser harness. Also how to mount the two shell connectors and the cross-connect connectors
is still open.

The communications system consists of a Kantronics KPC-3+ TNC, a Hamtronics
transmitter and receiver and a custom interface board to hook it all together.
These are all mounted in a 1" tall box on top of the battery boxes.
