This was [...] This report and several others over the past several weeks indicate that periodic problems occur at the antennae facilities. Is this a real problem? Is antenna performance degrading over time? Is it a matter of lack of maintainence or are these outages beyond reasonable control?

Have they tried commands to switch to the receiver it's already using? Or maybe rapid transitions between the two positions (analogous to the old trick of getting a car out of a pothole by alternately shifting into forward and reverse). There might even be some resonant frequency that's especially helpful. I suppose they have tried it, but it doesn't hurt to ask. :-) John Roberts roberts@cmr.ncsl.nist.gov ------------------------------ Date: 26 Jan 91 04:34:07 GMT From: zaphod.mps.ohio-state.edu!swrinde!elroy.jpl.nasa.gov!zardoz.cpd.com!dhw68k!ofa123!Wales.Larrison@tut.cis.ohio-state.edu (Wales Larrison) Subject: Re: Commercial Space news (3 of 4) replacements and spares, are needed for the constellation. The winning company was not announced, and according to a Motorola spokesperson, the winning company will "announce their own success" once final negotiations are complete. Other subcontractors, including those to provide launch-services, have not yet been selected. Selection is depends upon formation of an international consortium to operate the system, planned for spring of 1991. [The 77 satellite Iridium constellation is the "plum" of current satellite business. However, the Iridium system still needs to obtain operating approval and a frequency allocation on a global basis. This is a very interesting and sensitive political and technical issue, since other countries (France, Japan, Germany, England, China, etc.) don't want a U.S. firm to lock up this market or these frequencies. Intelsat also sees this as a direct competition for their global monopoly for international satellite telecommunications, and they have a signed charter from over 100 countries (including the U.S.). Motorola has reportedly gained key support from several 3rd-world countries who see the Iridium system as very appropriate for their needs. But, until the global frequency allocations are made, and operating approval is in the works Iridium is still very vulnerable.] AGREEMENT REACHED ON COMET PROGRAM Verbal agreement has been reached on the Commercial Experiment Transporter (COMET) program, funded by NASA as a commercial procurement for a recoverable orbital experiment carrier capable of carrying and returning 300 pounds of payload into orbit, sustaining it for up to a year, and returning it to a soft land landing. Agreement was reached for funding the program through the first launch, which may come as early as 18 months from now. COMET team members Westinghouse, Space Industries Inc, and Space Services Inc agreed to work within the available funding profile of no more than $30.5 M through FY 1992. The program is coordinated through the Center for Advanced Space Propulsion, a NASA Center for the Commercial Development of Space (CCDS), and is a purely commercial procurement. The participating CCDS will purchase only launch, on- orbit, and recovery services. The contractors retain title to their requirement, and absorb any costs over that covered by the $30.5 M. This verbal agreement was necessary before the contractors can be given the official contractual "authority to proceed" with the 18-month program to first usage. Westinghouse is responsible for overall systems engineering and will also build the on-orbit service module. Space Services Inc will launch the system on a four-stage version of its solid-fueled booster. Space Industries Inc is responsible for payload integration and orbital operations as well as the recovery capsule. [Commentary: This project now looks like a "go", although there are still some possible major stumbling blocks to be overcome. Teledyne Brown had been the primary choice over Westinghouse for systems engineering and payload integration, but they were dropped from negotiations last week as they felt they could not meet the available budget line. According to speculations in the trade press, TB was unable or unwilling to absorb enough of the cost over the budgeted amount for the first CCDS payload in the expectation it would eventually recover the losses through future commercial work. The CCDS responsible had also tried to increase the funding made available from NASA's Office of Commercial Programs with no success. Space Services Inc. has had this as a must-win.
