Homework Solutions for SATCOM, Solar and Battery Power

Three more homework problems and solutions added to the Satellite Communication class dealing with satellite power issues, and a remaining orbit geometry problem I left out in an earlier post. Spacecraft battery power demands are examined, also a problem looking at the spinner satellite designs solar power efficiency has been provided. These items are located at:

HW 12 - Solar Power
HW 13 - Orbital Geometry
HW 14 - Battery Capacity

New Sitemap Added

This weekend I updated the site map for FreeClassNotesOnline. The site index was for 487 pages and I used the XML-Sitemap.com generator. Up to this point I’ve only used this generator to create my .xml sitemap file. But I’m now running into a slight issue; this generator only is free for sites under 500 pages and now that I’m starting to go beyond this page count I’ll need to find another page generator.

Site Redirecting is Working

Success! I’ve been knocking out some site maintenance on FreeClassNotesOnline.com, more specifically the transfer conversion from the old site. I’m now redirecting most if not all the site pages so I anticipate most if not all my traffic numbers will drop off for the old site and jump up in December for the new site. Yahoo! Let’s face it, I’m not the most savvy internet guru; I’m an electromagnetic geek so little “oh yea it freaking worked” happy moments I come across while banging away on the site are major achievements for me. And let’s face it, the more I can get the site operations seamless for my audience (aka all of you reading this), the more time I have to knock relevant content for the site. Well all, I’m going to keep a close eye on this traffic redirecting in the coming weeks. If you see any issues please let me know. Cheers. -Brian

Site Maintenance Work

I just ran this evening the Xenu link checker for broken links on the site. I had zero orphan files, a good thing; but out of 498 text URLs and 572 image URLs, and accounting for a total of 1287 URLs including external links to, I have 31 not found URLs I need to investigate.

Beyond this, I’m sort of on the fence about the old site. Part of me wants to just redirect the master index page but also part of me wants to create individual linking pages which will not only take time but take quality time away from building the real site, FreeClassNotesOnline. Any suggestions or comments? -Brian

Why It’s Been Quiet?

Hello all. It has been way too quiet on this blog so what’s going on. Over the last six weeks or so I wrapped up a consulting project which is my primary source of income at this stage and simply put, I needed mental break. I totally enjoy the science and engineering I do in my suit-n-tie professional career; but even as a consultant, the Dilbert moments which are often get annoying. Therefore, in early October I popped over to Rome Italy for a few days, and then hopped on the new Carnival Dream ship and did the sixteen day transatlantic cruise back to the United States. I’ll put up a few blog post about the new ship in coming days so stay tune for those posts.

For now, my head is clear and I’m back in force crunching away in finishing up the Free Class Notes Online transition which I’m happy to announce I’m days away from completing. As I make this shift please let me know of any errors you come across, or any feedback. I’m pulling in about 3000 visitors a month now and I enjoy hearing from all of you. Until my next post, Cheers all. -Brian

Site Migration Statistics

Today, I looked over the site transition data to evaluate how my traffic and page views are migrating to the new site, FreeClassNotesOnline.com Turns out, in just the last two months sense the acquisition was made the data looks great and I’m driving traffic to my new site. I plotted the Visitors and Page View numbers and anticipate the visitors data will converge sometime around November or December this year.
