Due to ITAR, unfortunatly AMSAT-NA had to\nstop all it's official support (including money, which hurts) for P3-E\nseveral years ago, as you wrote.. For example, we had to re-build and\ncontinue the IHU hardware and software development on our own resources.\nThe same for the original SDX development, etc. The S/C is still\nsitting in our clean room in Marburg and waiting to be finalized. Having\nno firm launch date yet, activities slowed down in some areas, while\nother activities and groups are highly active and well alive. The\nbiggest problem is indeed having no firm launch date yet.. this is\nfrustration for everyone involved. We all put so much volunteer work and\ntime into it...\n\nWhen I read \"Forget P3-E, build an MEO\" (that's how I read it first) I\nwas indeed very concerned.. should we really forget all the hard work,\ntime and money which already went into the project and scrap it??? And\nwhat than? No - I'm not giving up...\n\nOK, reading the second time I understood that Dave meant we should put\nP3-E on VEGA and use it's propulsion to go to MEO...\n\nUnfortunately things are not so easy.. P3-E was designed to go from GTO\ninto HEO. For example, all the magnetic attitude control won't work in\nMEO anymore, etc.. Thus we were looking for GTO, but would it fit on\nVEGA? Indeed, we could try an elliptical orbit with a much lower\napogee, but than we have to carefully study the effects of orbit\nresonances which caused AO-13 to burn-up too soon. However, I do\nsympathize with the idea and we thought about it in the past, but\ndiscarded the idea for reasons I have almost forgotten now. So,\nperhaps we should look again at it.. do some orbit and fuel\ncalculation, study orbit perturbations and orbit stability again and see\nwhat the impact will be on the S/C design. Any volunteers for that?\n\nAs Nitin wrote, we contacted AMSAT-India to help with contacts to\nISRO, we are in contact with SpaceX and I recently had a personal\nletter exchange with the CEO of Arianespace. If a launch possibility\narises, we will be on it. It is not always a matter of money, but also\na matter of compatibility to slip in. Ariane-5 for example is a real\nworkhorse now with standard launch configurations. Any change on that\ncosts them a lot of money. If there is an \"unusual\" configuration were\nthey have to ask industry for a configuration change, than it might also\nbe easier for us to slip in..\nThat simply means we have to wait for the right moment or finding new\nqualification flight.. Ariane 5ME is such opportunity we are actively\nworking on, but this will not be before 2018.\n\nIn the last several month our work and priority was mostly focused\nregarding our funding situation and to improve it. Although most people\nstill did not understand it, but the P5-A project is one these\nopportunity we need. It is well alive and currently heavily discussed\nwithin the highest ranks inside of our government organizations. Apart\nfrom this, we are currently working on another project to fly an hosted\npayload on a GEO satellite... A decision is not made yet, but if we get\nthe opportunity it will provide some neat communication capabilities.\nOur previous heritage and P5 will help here too..\n\n\nI'm currently having some serious family matters to take care off, so\nplease be patient if I do not reply quickly..\n\n73s Peter DB2OS\n\n_______________________________________________\nSent via [email protected].
