Category Required (was Re: Orphaned and uncategorized files and articles in EaglePedia)

Hi Stephen, Part of the upgrade was to install an Extension to the core MediaWiki software that does not allow you to save an orphan pages. Whenever you edit a page this extension checks to make sure that there is at least one [[Category:something]] reference. The NOTICE is pretty much the instruction - simply add in the category as shown in the NOTICE and substitute the appropriate Eagle category for "something". You can then save it. I have discovered one problem with the "Category Required" Extension. If you are editing a section (the edit link to the right of a section header) it still checks for a category. I think this is punitive, so I have contacted the "category required" extension author. The work around is to either edit an entire page or duplicate the category reference in the main article. 73, Emily At 08:29 PM 11/27/2006, you wrote: >Emily, > > Going slightly nuts am I? > > Every time I edit an existing page (attempting to correct missing > file links, etc.) I get a: > > "NOTICE: There must be at least one [[Category:something]] link." > And no save!

Orphaned and uncategorized files and articles in EaglePedia
by Emily Clarke 27 Nov '06

27 Nov '06

Since the upgrade, I made a big effort to improve the navigation in EaglePedia and now that the coding changes are completed spent some time going through EaglePedia to see how well things have improved. The answer is that it is still difficult to locate articles and files in EaglePedia - mostly because things are unused or uncategorized. It would be very helpful if the uploaders/article authors could review the list of unused and uncategorized files and add categories and link them into an article (even if that article is just a short summary.) An unused file is a file that has been uploaded and hasn't been linked into an article. For true images (JPEG, GIF or PNG) this means there is no article that contains the embedding reference (for example) [[Image:MyImage.jpg]] to display it. For non-image files (PDF or DOC) this means there is no article that references it using (for example) [[Media:MySpecification.pdf]] You can find a list of unused files (and the name of the user who uploaded it) here: http://www.amsat.org/amsat-new/eagle/EaglePedia/index.php/Special:Unusedima… Files should also be categorized when uploaded. This means that when the file is uploaded you should add the category it falls into. This which should normally be the same category as the article that will reference or embed it. Before you upload a file you should probably browse the project categories (now shown on the front page of EaglePedia) and locate the appropriate category. When you are at the file upload screen add the category into the summary by typing in [[Category:This Category]] To see a list of uncategorized files go to: http://www.amsat.org/amsat-new/eagle/EaglePedia/index.php/Special:Uncategor… To categorize a file that is already uploaded without uploading another copy click on the "Edit" tab at the top of the description page, and then add the category information as shown above. Thanks in advance! 73, Emily --------------------------------- N1DID formerly W0EEC - CM87tm Support Project OSCAR - http://www.projectoscar.net

EaglePedia Upgrades
by Emily Clarke 16 Nov '06

16 Nov '06

EaglePedia is online and most everything is working. The exception to this is that the WYSIWYM editor doesn't work. One of the dependencies (a perl routine) has not been installed. It should be shortly, but if you try to use that functionality you will receive an error that basically says a required module is not installed. Everything else is working - I encourage everyone to read the online release notes: http://www.amsat.org/amsat-new/eagle/EaglePedia/index.php/EaglePedia_1.1_re… This should explain the upgrade. 73, Emily --------------------------------- N1DID formerly W0EEC - CM87tm Support Project OSCAR - http://www.projectoscar.net

Re: Solar Power Systems -- White Paper FYI

Tom, We've been watching this subject for some time in ITU-R Study Group 1 (spectrum management). As I'll be traveling this week, I've asked Jon Siverling to review the relevant ITU documents and advise. Paul At 01:59 AM 11/11/2006 -0500, Tom Clark, K3IO wrote: >>>> I am a member of URSI (International Scientific Radio Union) Commission J (Radio Astronomy). The US National Committee of URSI has asked its members to review the attached document on Orbiting Solar Power Stations. I send it along to you for information. You will see that the concepts might involve Microwave Power transmission at S-Band (2.45 GHz) and/or C-band (5.8 GHz). In the main footprint of the beam, the power flux density might reach (near fatal!) levels of ~300W/m. The orbiting antenna will certainly have sidelobes likely would wipe out many services. You will note comments indicating that that this worries many radio astronomers who routinely make measurements as sources with flux densities of 1 mJy (1 Jansky =s a power flux density of 1x10e-26 w/(mHz) . In the event of a failure of just one active element, the beam-forming properties of the orbiting antenna would certainly degrade. Inside the report you will note a statement that even with a MTBF of ~30 years for magnetrons, this implies a failure of one element/day for the array! It is interesting to note that the report indicates current launch costs of ~$10,000/kg (this is about the going rate for a Dnepr launch to LEO), decreasing significantly by 2025 (good news for us, if true). It is also interesting to note that the report still indicates the use of (relatively) low efficiency solar cells and doesn't even note the ~28% cells that we have been using. I have no idea of the reality of these systems. I presume that AMSAT/ARRL/IARU could make comments to URSI. The following is the "charge" given to URSI members which calls for responses a scan 1 weeks hence: <fontfamily><param>Helvetica,</param>Dear USNC-URSI Colleagues: The past president of URSI, Professor Kristian Schlegel, has asked me for the USNC opinion on the proposed URSI white paper on solar power, copy of which is attached. Even though it appears that the conclusion is foregone because a majority of URSI member countries are in favor of the proposal, it is important that the US opinion be registered and our objections, if any, be forwarded to URSI and remain a matter of record. I am therefore asking that you let me have your reactions by e-mail on or before Monday, November 20. I will collate them into a memorandum that I will send to Prof. Schlegel by his deadline of November 22. It is especially important that I hear from the Commission Chairs, and crucial that I receive the opinion of Commission J. I apologize for the short notice. I was hoping that we could discuss this matter at the USNC business meeting in Ottawa next summer, but it now appears that URSI is in a hurry to decide the issue soon, and is not willing to wait. Best regards, George Uslenghi Chair of USNC-URSI. _________________________________________ Piergiorgio L. E.

Many of the issues with this project are beyond the technical scope of the URSI commissions and hence it is inappropriate for URSI to take a strong position on this project. Individual commission J members expressed strong reservations about this project and do not want to be associated with a white paper supporting solar satellites for beam power to earth.

New integration lab, new relationships
by Robert McGwier 09 Nov '06

09 Nov '06

This note is informational and not for publication. The official announcement will come from Rick Hambly on behalf of AMSAT and be made in the form of a press release. Let me say that I consider these happenings to be a serious beginning of the activities towards a real spacecraft. I want to apologize for my being a wee bit quiet in the last few weeks but there have been nice things brewing. A few weeks ago, Bob Davis, KF4KSS, and I had a conversation about his future in business and his future with us. Bob was an AMSAT employee in the labs in Orlando during the integration of AO-40. Many credit Bob with doing some of the best work done in the mechanical area during that program. Bob was a aerospace engineering student and AMSAT made a great move hiring him. Dick Jansson, Lou McFadin, Jan King, Karl Meinzer, and more were/ are universally supportive of Bob and his abilities as a spacecraft mechanical engineer. After the AO-40 program "went to bed" and into orbit, the Orlando activity wound down. Bob wound up at SpaceDev and was an important part of the Chipsat program. He eventually left SpaceDev as their fortunes changed (which had nothing to do with the spectacularly successful Chipsat) and became an employee of Swales, a well known aerospace firm in the D.C., Maryland,Va. area. Bob and his peers became successful and landed a good support contract with Wallops-NASA. Eventually, they decided to leave Swales and join the University and the Maryland Hawk corportation and to become an important partner to the university, Wallops, and now AMSAT. When it became clear to me the scope of their ambition, and many other factors, but most importantly, having Bob Davis involved, I recommended to Rick that we consider this as our new facility. Rick Hambly, Tom Clark, Jim Sanford, Bob Davis and I have been working with the University of Maryland on the eastern shore and this spin off of the university called Maryland Hawk Corporation with the goal being to enter into a working relationship that we hope will last for years. Maryland Hawk operates the Hawk Institute for Space Sciences in Pocomoke, Maryland. HISS has access to the spacecraft engineering facilities at Hawk and at Wallops (including machine shop, thermal vacuum chamber, and shake/shock test apparatus). The University of Maryland branch affiliated with HISS is in Princess Anne. Md. They are both within 1/2 hour of NASA's Wallops facility. We have decided that this is a spectacular opportunity for AMSAT to do a win-win-win deal. The deal is done on AMSAT's side. The AMSAT board of directors unanimously approved a memorandum of understanding with the University of Maryland and another with Maryland Hawk. Maryland Hawk will be our integration and testing facility. We will have 6000 square feet of machine shop and integration facility. The clean room from AO-40 will become the first clean room in the new facility. The employees of HISS will be on our satellite building, testing, and integration team along with lots of help from volunteers but we will definitely have a superb core unit on site at all times. This will also allow us to maintain the controlled access which will be required (legally) for our operations. Hawk is very ambitious and AMSAT is going to get ambitious with them. HISS is a not for profit, 501c3 organization (like AMSAT), affiliated with UMES through the Hawk corporation. UMES is attempting to grow their involvement in providing excellent technical jobs in the area and to increase the content of their curriculum. AMSAT will assist HISS in working with Cubesat, small sat, etc. of all types. The members of AMSAT that choose to work with HISS on their programs will be encouraged to do exactly that and with AMSAT's blessing. AMSAT types would be adjunct faculty at UMES and UMES will support us with local facilities and student involvement in our projects. HISS wants to become a player in all sorts of small satellite activities and AMSAT, in concert with these two groups, wants to seriously enhance its educational profile. I am very excited about this opportunity for AMSAT. So is the board of directors and the Eagle Project manager all of whom have been terrifically supportive and actively involved. The board asked lots of tough questions, and were quite careful with AMSAT's interests here. On a personal note, I REALLY like these people at UMES and Hawk. They are "our kinds of folks". They are aggressive, ambitious, and have a vision of where they want to go. I want us to go with them and they want to go with us along the path we want to take our programs. We (unanimously) believe this is the right thing for us to do at this juncture. The launch environment has been undergoing major shifts in the last few years and major U.S. policy is about to be sprung on us. We believe this will impact us very positively. We believe we are poised to take advantage of this changing environment. With this new facility and the new environment, expect us to move out aggressively in several areas and keep your fingers crossed for results. We are working on a technical assistance agreement (a term of art in the ITAR/Import/Export regime) that we will submit to AMSAT-DL, AMSAT-UK, etc. so we can again enter into working relationships with them as well and to do it with the blessing of the U.S. government (which is now required). I thank each and every one of you for your spectacularly generous contributions to AMSAT and we hope we are now poised to take maximum advantage of these contributions. I have attached google earth map pointers to the University, the HISS facility, and finally to the "visitor center, launch viewing area" at Wallops. Please remember, you are not authorized to release this. We have an agreement with the university and Hawk about press releases and this is not one of them! Thank you all for your patience.
