'OLD TYPE' Orbit No : 0 Eqx date : Mar 1st 1984 Eqx time : 18:59:25 GMT Eqx long : 320.38 deg.w Mean hgt : 687 km Period : 98.5045 mins P-drag : 8.3E-6 *N-ref Long inc : 24.6251 degs L-drag : 2.1E-6 *N-ref Inclination : 98.26 degs 'KEPLERIAN TYPE' Afiliation Set : UOS-G3RUH/1(pre launch) Epoch time : 61.7990741 19:10:40 GMT March 1st 1984 Inclination : 98.25967 deg RA of node : 124.24 deg Eccentricity : 0.0004139783 Arg of perigee : 174.17 deg Mean anomaly : 227.01 deg Mean motion : 14.61862 rev/day Decay rate : 1.8E-5 rev/day^2 Epoch rev : 0 Semi Major Axis : 7065.31 km If launch time changes. For 'OLD TYPE' : add/subtract correction to Eqx time. For 'Keplerian' : add/subtract correction to epoch time AND add/subtract 4.178E-3 deg/sec to RAAN These, by the way, are similar to PKARN's numbers (but not exactly the same !)

Anyone interested : Uosat-1 is now on, and will stay on for most of the w/e. It is sending telemetry. Mac Posted: Thu Feb 23, 1984 11:27 AM PST Msg: HGIE-1724-4487 From: LKAYSER To: AMSAT Subj: STATUS UOS-B THUR PM AUTOLINK OTTAWA TO EVERYONE GANG, 1.5 man months were expended yesterday during the premate (32 people * 12 hours). The problems were too numerous to go into here, I've got several minutes of video tape you can all look at some time. There where no problems attributable to uosat-B. We called it quits at 4:00am and got it again at 10:00 this morning. We should be ready to go to the pad shortly after noon today, if nothing came up. Larry, pls forward to TM, thanks. END, REGARDS LARRY Posted: Thu Feb 23, 1984 9:01 PM PST Msg: CGIE-1724-8162 From: HPRICE To: amsat CC: msweeting Subj: Uosat-B status, thursday evening. Gang, Just got back from the mate. The 1 hour procedure lasted from 14:00 to 20:00 and still isn't done. Some of the things that were done last nite got disaproved overnite and had to be redone. Some new problems cropped up at the pad. The caps on the pyros still need to be put on, and one of them looks like it will hit the 1.2 Ghz antenna support which may require milling of something somewhere. Two 2m/70cm antennas need to be put on and the array covers removed. We had to clear the pad for the Landsat guys so Martin will finish up tomorrow. Although all the over time business seems dire, there should be no problem getting launched. The NASA and MDAC crews have been great, as has everyone else. It was a real experience, hopfully the hour + of video will give you some of the feel of the goings on. Most of the Surrey crew leaves for LA tomorrow morning, Martin stays till the weekend and Ian stays for the launch. The Surrey crew going to LA leaves for the UK at 20:00 Friday. Collin is staying with me thru launch. That's it from here, back to packing. (Colin points out that there is only one L in Collin, but what can you expect from a bloke who spells color wrong?)

Status as of 4PM EST today is all mounted with only a plastic bag to remove and some minor taping to do. Farings are next, main crew leaving Sat for UK unable to leave today due to strike action on airline. things are looking good regards to all, Larry Posted: Sat Feb 25, 1984 2:00 AM PST Msg: TGIE-1725-8627 From: HPRICE To: amsat CC: msweeting Subj: Uosat-B status, friday nite We (Colin, Roger, Dave, Mike, and Nevil) arrived in LA around 19:00 this evening. Part of british airways is on strick, so they won't be going out today. This has also made shipping the bits of the ground station to Surrey in time for launch somewhat of a trickey proposition as well. Perhaps more trouble on the ground means less trouble on orbit. Martin just called after getting back from the (22:00 local) to say that the fairing had been installed and there was 1/8" to spare. After final positioning, we have one inch clearance, even more than called for. All is well, we got past the two last hurdles, the fairing installation and the F-3 review. The F-3 review is the last major planned time when UOSAT-B could have been disapproved and de- mated. We passed. The only open item before launch can be approved is checking for correlation between the solids on the delta and the failed solids on the PAMs on the last shuttle mission. The has to be looked at but is not viewed as a highly probable item. Anything can happen between now and 17:59 utc Mar 1, but all is go at this time. The 1.5 hour of video tape came out well. Many pics were taken. Details on availability when available. Harold. The only thing left is removal of the safe plugs and installation of the arm plugs, shortly before launch.
