Purpose: Orient team so far to science, study context, and pre-work plan for EDS
Attendees:
Chris Hostetler – founding member of Calipso, science lead for instrument
Chip Trepte – lead scientist
John Hair – instrument lead
Beth Brumbaugh – organizing information
Ron Verappen- I&T, operations manager for Calipso
Will Scott – electronics for Calipso; power
Jamie Wilson – orbit and ops
Marie Ivanco – SMAB, DSE for MESCAL
Kerry – SIE for EDS, did software for LITES, precursor to Calipso
Dave Winker – PI, working with CNES on pre-phase A study for MESCAL
Bob – Cost for EDS
Vip – senior SE, EDS Facilitator
Angela Welters – electronics
Jeff Brady – mechanical
Tony Notari – optics
Chris Thames – software
See slides for more detail, but some main orienting points:
HSRL gen1 flying on aircraft for 10 years, added seed laser and frequency locking in transmitter, and aft optics assembly that proved that long-term lidar would work: (2b, 1a, 2d)
HSRL gen2 flown for 5 deployments, added ACE capability, interferometric receiver and laser output at 355nm: (3b,2a,3d)
Approached by CNES to join next lidar, Langley added aerosols (from ACE mission; IDC 2007) and oceans (from 2011 proposal for EV mission to ISS; OPAL)
Have measurement requirements
Goal:
- Minimize cost, risk, Maximize science value to finish phase A study
- build corporate knowledge for lidar in space, design and development of spaceborne HSRL
- ready to respond to next Earth decadal survey (have info on 3 options), so ready to develop, build software and hardware
Objectives:
- Evaluate TRL
- Ready to make agreement about CNES part of instrument development, so close look at instrument subsystem interfaces
- Find major cost savings by discipline (knees in curve of design vs cost)
- use Kathy ‘s lidar simulator to evaluate, and give feedback to improve simulator
Deliverables:
- mass, power, volume
- cost inputs (dev and build labor and time)
- drawings
- input to run simulations in February
- first draft of powerpoint summary for subsystems and systems eval ?
- cost estimate Feb. 5
Schedule:
1 week full days for design in January 25-29th
Last 1.5 days to look at 2 other concept options?
Cost iteration the next week individually
March meeting with CNES
November EDS to refine full instrument concept (fuzzy timing and goals until post-Jan-EDS)
Team:
EDS team
Facilitator: Vip – main interface with Chris Hostetler, Dave Macdonnell, Paul Speth?
SIE: Kerry – maininterface with Tory and Marie
SEDoc: Matt? or Tammy/Kevin L./Hilary? – interface with Beth, Marie, Tory
Cost: Nani/Bob (last day plus week after session) – interface with Marie
Anyone below that branch heads don’t agree at the Integration Forum to staff as part of project effort (weekly meetings) – thermal and structures?
MESCAL team
Study Lead (interface with Vip and lead pre-work details) = ? Tory? Dave? Chris?
Mechanical: Jeff Brady
Opto-mechanisms: Charlie Boyer
