E-MAIL: Michael J. Kinkelaar, Michael.J.Kinkelaar@lerc.nasa.gov. This notice is a combined synopsis/solicitation for commercial items prepared in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; offers are being requested and a written solicitation will not be issued. This notice is being issued as a Request For Offer (RFO) for: Delivery of 1 Complete Satellite Antenna System including antenna, feed system, positioning/pointing system,automatic de-icing system, lightning protection, aircraft lighting, cables and documentation in accordance with the following Specifications: ANTENNA SPECIFICATIONS The antenna system shall include the following subsystems and meet or exceed the following minimum specifications: 1.0 Antenna 1.1 The Antenna shall meet or exceed all Intelsat Standard E-3 performance specifications for Ku-band ground stations. Specifications are contained in Intelsat Earth Station Standards Document IESS-208. These specifications shall be met for elevation angles of 10 degrees and higher for the configuration described in this document. 1.2 The antenna shall be of a high quality rugged design suitable for use in commercial environments. 1.3 The antenna and mounting system shall be able to operate with wind speeds of up to 90 MPH and survive with wind speeds of up to 125 MPH for any antenna position. 1.4 The antenna performance shall meet or exceed Federal Communication Commission (FCC) regulation Part 25.209 for 2 degree satellite spacing. 1.5 The antenna transmit standing wave ratio (SWR) shall be 1.3:1 or better. 2.0 Feed System 2.1 The antenna system shall include a 4-port, Ku-band feed system incorporating linear polarization. The feed system shall include two ports for transmit (one horizontal, the other vertical) and two ports receive (one horizontal, the other vertical). 2.2 The feed system shall be broadband with a transmit bandwidth (3 dB) from 14.0 GHz to 14.5 GHz, and a minimum power handling capability of 500 Watts. 2.3 The feedsystem shall be broadband and cover the receive frequency band to 12.75 GHz with no more than 3 dB variation (3 dB bandwidth). 3.0 Positioning / Pointing System 3.1 The positioning system shall be of a motorized dual-axis elevation-over-azimuth construction and permit a minimum of 110 degree continuous rotational travel in azimuth under computer control. The elevation drive system shall permit accurate positioning between 5 degrees elevation and 90 degrees elevation under computer control. 3.2 The polarization drive assembly shall permit continuous rotational travel of a minimum 180 degrees of rotation for the feed assembly. 3.3 The positioning system shall include digital resolvers which can discern position to within 0.005 degrees for both Azimuth and Elevation, and to within 0.05 degrees for polarization. 3.4 Azimuth and Elevation drive motors shall have a minimum of two selectable travel speeds ( drive speeds ). A variable drive speed design is also acceptable, but must still meet the travel speed requirements herein. The fast speed is for rapid repositioning of the antenna toward a new satellite target. The slow speed is for maintaining accurate pointing ( tracking ) toward a geosynchronous satellite in inclined orbit. 3.5 For the slower tracking speed, the azimuth and elevation drive motors shall have a speed between 0.01 and 0.025 degrees/sec (each axis). 3.6 The azimuth and elevation drive motor when operating in fast speed shall have a minimum speed to reposition the antenna of 0.1 degrees per second (each axis). 3.7 The positioning system shall include limit switches and electrical interlocks to protect the antenna and positioning system from accidental damage from over-running a travel limit,and to ensure worker safety when servicing the system. 4.0 Tracking System 4.1 The antenna system shall include a computerized satellite tracking system. The system must be able to track the orbit of geosynchronous satellites operating in inclined orbits. 4.2 The tracking system and positioning system shall be able to accurately position the antenna to within 0.01 degrees for both azimuth and elevation, and to within 0.2 degrees for polarization. 4.3 The tracking system shall include memory presets for storing a minimum of 30 satellites in geostationary orbit and a minimum of 5 satellites in inclined geosynchronous orbit. 4.4 The tracking system shall have a minimum of two tracking modes: 1) accept keplarian orbital elements to predict and track the orbit of a satellite based upon time of day. This mode of opertation is generally known as "programmed track", 2) include "step-track" mode of operaton where the signal strength output from a beacon receiver is used to track the path of the satellite thus maximizing the received signal strength. 4.5 The tracking system shall be compatible with, and take advantage of, the dual speed drive motors of the positioning system or permit variable speed operation if so equipped. 4.6 The tracking system shall include a "manual jog control unit" for manual positioning of the antenna system. 4.7 The system shall include capability for remote monitoring and control of the tracking system through at least one of the following interfaces: RS-232, RS-422, Ethernet, IEEE-488. The intent here is to be able to monitor and control the antenna system from a remote location in another building during unattended operation. 4.8 The positioning system shall include a tracking receiver used to monitor beacon signals transmitted by the satellite and output a signal strength indication for use by the "step track" positioning system. The tracking receiver shall be able to tune signals in the 10.95 to 12.75 GHz frequency band. 5.0 Automatic De-icing System 5.1 The antenna shall incorporate an automatic "hot air" de-icing system to prevent ice buildup on the antenna surface, and for the antenna feed. The de-icing system shall also include de-icing of the sub reflector if so equipped (Gregorian subreflector designs). 5.2 The hot air shall be heated using electric heating elements. Power for the heating elements shall be double insulated. 5.3 The de-icing system shall incorporate a temperature sensitive control system to automatically turn the heating system only when needed. 5.4 The de-icing system shall include electrical interlocks to ensure worker safety when servicing the system. 6.0 Lightning Protection 6.1 The antenna system shall include a lightning protection kit. 7.0 Aircraft Lighting 7.1 The antenna system shall include aircraft lighting. The lighting kit shall be compliant with applicable FAA regulations. 8.0 Cables 8.1 The system shall include all necessary cables to interconnect the antenna,drive motors,and de-icing systems to a nearby equipment shelter. The equipment shelter is located approximately 100 from the base of the antenna foundation. 9.0 Documentation 9.1 Two complete sets of documentation shall be delivered for each item (1-8) above. This applies to the standard documentation which normally comes with each unit and includes operators manuals, maintenance manuals, parts lists, installation drawings, and wiring lists. 9.2 Within one month after Receipt Of Order (ARO), the contractor shall provide two copies of any applicable foundation drawings and related materials necessary for NASA to properly prepare the site where the antenna is to be located. These materials may include such items as the recommended concrete foundation design, power requirements, recommended grounding system, etc. 10.0 Delivery 10.1 The price quotation shall include delivery to NASA Lewis Research Center in Cleveland, Ohio within six months after receipt of order.
