So Arisssat or suitsat 2 whatever it is called is now going to be ready at the end of 2010?

Just to give everyone a little update on how the AMSAT NextGen Program is doing @ Binghamton University . . .
(a) CONTROL & EXPERIMENT SYSTEMS
- The Systems Engineering students are doing well analyzing the ARISSat
documentation and will be scheduling meetings with the primary AMSAT engineering contact to discuss documentation questions.
- Identified Design Changes Needing to Occur for NextGen:
- The Control/Safety Timer needs to be adapted to conform with the
CubeSat deployment switch standard
- Consolidation of Camera functionality into a separate camera payload
board (functionality is currently spread across a number of boards in the stack)
(b) RF SYSTEMS
- The Systems Engineering students are doing well analyzing the ARISSat
documentation and will be scheduling meetings with the primary AMSAT engineering contact to discuss documentation questions.
- Identified Design Changes Needing to Occur for NextGen:
- Antenna design choice - single dual-band vs dual mono-band
- New RF container design needed
(c) POWER & STRUCTURE SYSTEMS
- The Systems Engineering students are doing well analyzing the ARISSat
documentation and will be scheduling meetings with the primary AMSAT engineering contact to discuss documentation questions.
- The Hardware Engineering students have been busy creating a
preliminary design for solar panel deployment and use of supercapacitors to replace the battery. A Preliminary Design Review is being scheduled in mid-November with the AMSAT Engineering Team.
- Identified Design Changes Needing to Occur for NextGen:
- Replace Battery with modular stacks of Supercapacitors in parallel to
the Solar Panels
- Shrink ICB (Interconnect Board) to fit within CubeSat frame
- Reduce PSU footprint by moving camera power function to a Camera
Payload Board (CPB)
- Slight PSU voltage supply design change
- Remove test/program load functionality from ICB to external test board
(XTB) via standard CubeSat & PPOD maintenance ports (per CubeSat spec.)
We are still on-target to have an engineering model ready for the AMSAT table at the 2010 Dayton Hamvention with readiness for launch later in 2010.
