Charge:
Is the project as presented capable of achieving its goals with the resources provided and in the time frame available?
Please provide written comments and recommendations, separately or as a group.

4. Project Motivation
Keep Blanco operating as a state-of-the art facility
DECam, imposes some specifications, DES and the community.
NEWFIRM, another potentially very efficient observing facility
Existing instruments
Retire & replace obsolete components
The existing system incorporates many obsolete and obsolescent components and technology.
Some components are home built with off-the-shelf options now available.
The power amplifiers are originals.
The mode-switching control model significantly constrains performance and was driven by the limited technology available at the time.
Modernize software
Modern servo technology, both and sense and drive ends, has advanced significantly since the last upgrade (20 years ago!).
Can improve delivered image quality

5. Project Motivation Modernize software Modularize
Interfaces are dated
Capabilities are limited by today’s standards
Much useful telemetry is dropped on the floor
Modularize
Existing system is highly centralized
Control and servo functions are blended
Improve maintainability
Maintenance and modification get harder each year
LSST prototyping
An opportunity to capitalize on SOAR experience and develop essential experience for LSST
Consolidated TCS support for 3 major telescopes.

6. Goals Maximize telescope efficiency for DECam/DES/NEWFIRM operations
Replace obsolete & obsolescent components
Replace wire-wrap & bread-boarded components with off-the-shelf and PCB components
Use technology with an estimated >5 year market life

7. Goals Decouple mount, dome, rotator/guider from TCS
Use SOAR/LSST model & components
Set point / Status model
Labview, Ethernet, Linux, new PMAC, Wallace kernel, comms middleware (DDS)
(In the longer term, plan to retrofit SOAR with Blanco innovations.)
(In the even longer term, plan to retrofit SOAR and Blanco with LSST innovations.)
Introduce independent local and/or remote intelligence where appropriate

8. Goals Use new encoders Integrate all existing instruments
higher resolution, greater reliability, precision
Integrate all existing instruments
Mosaic II, SISPI, Hydra, RC Spec, (NEWFIRM)
Record and make available all telemetry from telescope to weather
The upgrade is to be performed with existing TCS in place

9. Specifications Slew requirement: 2 degrees in 17 sec
To match DECam readout time
Slew, project goal: 3 degrees in 20 seconds, track-to-track
Tracking: <0.5” drift in 60 sec everywhere within the DES area
Jitter: 100 mas r.m.s.
Guide error signal delivery rate: 1 Hz
Operational deadline: Sept 2010.
