Steve Carnes, 8:59 AM 12/23...,KidSat Status Report, Week ending 23 Dec 94 - 1 Received: by macvax.UCSD.EDU (5.57/UCSDGENERIC.4) id AA19240 to ride; Fri, 23 Dec 94 08:54:43 -0800 X-Sender: scarnes@128.54.128 Message-Id: <ab20b21804021004467e@[139.169.87.148]> Mime-version: 1.0 Content-Type: text/plain; charset="us-ascii" Date: Fri, 23 Dec 1994 08:59:40 -0800 To: john.f.muratorel@jsc.nasa.gov, mbaine@deimos.ucsd.edu, RIDE@macvax.ucsd.edu, rreed@bithound.jpl.nasa.gov (Randy Reed), scarnes@ucsd.edu, sgonzale%JSCDJ@JESNIC.JSC.NASA.GOV, Steve_Wall@radar-email.jpl.nasa.gov, way@lor.jpl.nasa.gov, wiskerchen@eureka.ucsd.edu From: scarnes@ucsd.edu (Steve Carnes) Subject: KidSat Status Report, Week ending 23 Dec 94 - Merry Xmas. SUMMARY: Met with COTS software vendor, hardware installers, COTS user, NASA Front-End. Raided training library. KidSat has Sharon Castle assigned as Payload Integration Manager (PIM), will meet with her first week in January. KCA is best approach for KidSat telemetry. Still have a lot of questions about the ESC. Link into KidSat gateway is a concern. Saw part of first simulation using DEC Alphas in new Mission Control Center. Culmination of one year of teamwork. Impressive. COTS Met with Tom Silva (programmer/entrepreneur) regarding Commercial Off The Shelf (COTS) telemetry. He writes DOS software that can read telemetry streams coming from JSC. Note that the Ku-Band Comm Adapter (KCA) eliminates need for COTS approach. Suggested minimal crew interaction - if KidSat crashes, box it up. Otherwise, lots of "in case of failure" procedures for Flight Operations. 9 month lead time on software to Flt Ops, plus crew and malfunction manuals. Hardware installers Met with contractors Barbara Robichaux (Rockwell) and Al Mays (Allied Signal) regarding POCCs. They install POCC computer hardware, software is done by users. Received POCC capabilities document, reviewed procedures. They are moving towards a generic POCC. Again, KCA would replace POCC approach, simplify KidSat paperwork. COTS User Met with Steve Jennings, NASA user of Tom Silva's COTS. Tabular telemetry data, not generally applicable to KidSat. NASA Front End Met with Brian Boland (NASA) on Front-End. KCA route would simplify KidSat paperwork load significantly. Of four main electronic communication paths to the orbiter, Text and Graphic Services (TAGS) has the lowest security requirements. Boland recommends using KCA through the TAGS route to the Network Output Multiplexer (NOM) rather than POCC through the Command (CMD) channel. Have been assigned a Payload Integration Manager (PIM), Sharon Castle. Will need PIM to approve security of KidSat gateway at CalSpace. Will contact her after she returns to JSC, first week of January. Electronic Still Camera (ESC) New information. Each ESC image is stored as 3 color RBG 6MB TIFF file (1.5Kx1K "virtual" pixels, 4 colors (R, G, G, B) per virtual pixel, 8 bits/color, 1 byte/8bits). may be compressed to approx. 3MB using Photoshop. After transmitting to ground, 3MB decompressed to 6MB, expanded ("interpolated") to 18 MBytes/image. Documentation Printed for sride@ucsd.edu (Sally K. Ride) 1
