It is published every week and is made available for unlimited distribution. * DOVE NEWS * ============= The following message from N4HY was recently carried on DOVE-1/OSCAR-17: DOVE-1>BRAMST : The new file system will be loaded to PACSAT and BBS operations will commence in the next couple of days. Upon testing file system there, DOVE will be reloaded. This will occur next week. 73 de BM Oct. 18 * PACSAT NEWS * =============== The MicroSAT BBS has been tested on the ground engineering unit, and is now ready for uploading to AO-16. The satellite BBS software was written by Jeff Ward, G0/K8KA, at UoSAT and was ported to the microsats by NK6K. The porting was easily achieved, as there are only 10 lines of code that are different between the UoSAT version and the Microsat version. A lot of effort went into the design of the BBS, operating system, and other support code to make that possible. Once complete, the following elements will be available: 256k file system: This is just half of one of the four available banks of bank switched memory. The more complete file system using all four banks and the 6MB mass memory will be uploaded after more testing. FTL0 file server: This implements the protocol described in the FTL0 document, available on CIS, the 9th ARRL Networking Conference proceedings, and elsewhere. It allows file uploading, downloading, and a simple directory display. It requires the use of software at the groundstation: a simple version, called "PG" has been written by Jeff and will be on CIS soon. Broadcast server: This implements the broadcast protocol as described along with FTL0 and has been running for several weeks on UO-14, and a few people have rolled their own receive program, at least one written in BASIC. A simple version, called "KISSUI" has been written by Jeff and will be on CIS soon. After this is loaded, the following separate programs will be running on AO-16: Kernel - Operating system - NK6K/Quadron AX25 - AX25 driver - NK6K/WB6YMH/Quadron, pd on a KA9Q AX25 implementation. PHT - Spacecraft control, power management & program loader - N4HY/NK6K AARTD - AART driver - NK6K/WB6YMH MFILE - File system - G0/K8KA/UoSAT FTL0 - File upload/download - G0/K8KA/UoSAT PBP - File broadcaster - G0/K8KA/UoSAT [Story via OSCAR-11] * OSCAR-13 NEWS * ================= Command Stations performed magnetorquing procedures near perigee of orbits on October 15-17.

It used to be that you could write your congressdroid and get a US flag that had flown over the capitol (or was it the white house? or both?). These got to be quite collectors items if they were in use on a notable day (trivia note... Nov 22, 1963? July 20, 1969...). However, demand got so great that eventually 3 flagpoles were installed adjacent to each other, and 3 people were employed to run flags up and down the poles (I think they let them fly for 30 seconds or some such time) in 8 hour shifts... -bw - Bob Wier -------------- insert favorite standard disclaimers here ---------- College of Engineering Northern Arizona University / Flagstaff, Arizona Internet: rrw@naucse.cse.nau.edu | BITNET: WIER@NAUVAX | WB5KXH or uucp: ...arizona!naucse!rrw ------------------------------ Date: 26 Oct 90 16:44:37 GMT From: mnetor!utzoo!henry@uunet.uu.net (Henry Spencer) Subject: Re: HST summary 10/22/90 In article <9010260035.AA25382@cmr.ncsl.nist.gov> roberts@CMR.NCSL.NIST.GOV (John Roberts) writes: > - The other major problem is the jitter in the solar arrays.

The reflector surfaces are painted white, and normally do not reflect enough sunlight to do damage. However, with our 27 meter diameter dishes at Caltech's Owens Valley Radio Observatory, we found out the hard way what happens when the dishes are shiny. We burned up four feeds in about a half hour one cold morning when the dishes were frosty. The sunshine melted the frost and made for pretty good specular reflection, costing us $8000 in repair bills. We have a brightness sensor now, that automatically scrams the dishes when over-bright. I suppose the problem is more acute with 70 meter diameter dishes. Dale Gary ------------------------------ End of SPACE Digest V12 #504 *******************
