Description

Market Survey: K/Ka/Q-BAND LOW PROFILE SATCOM ANTENNA SYSTEM FOR ON THE MOVE (OTM) OPERATION The US Army Communications Electronics Research, Development & Engineering Center (CERDEC) Space and Terrestrial Communications Directorate is interested in receiving information regarding low profile, innovative multi-frequency antennas that could be appl ied to COTM for SATCOM systems. It is envisioned that a new generation of agile wide frequency band antennas will be required to make communications on the move, over rough terrain, at high rate a reality for the Army Future Force. Specifically, communications on the move at high data rate will be supported over the transformational communications satellite, the advanced EHF satellite, wideband-gap-filler satellite and commercial KA band and KU band constellations. The government re alizes that a single antenna aperture may not satisfy all the bands of interest; however we are soliciting industrys perspectives on how these diverse constellations can be supported by a minimal number of diverse apertures. Future vehicles that would ho st communications on the move will be constrained in size weight and power and will have to wrestle with mutual co-site interference issues. The objective antenna is targeted for installation on a variety of vehicles including, but not limited to, a S832/A Standard Integrated Command Post System (SICPS) Rigid Wall Shelter (RWS) that will be transported and operated from an ECV-M113 vehicle, a B radley Fighting Vehicle, a STRYKER vehicle and various FCS vehicles. Size, weight and power consumption (SWAP) are of paramount importance, particularly for the Bradley, STRYKER, and FCS vehicles (less then 18 inch footprint). Conflicts, if any, between antenna SWAP and throughput requirements should be identified. The off-road vehicle dynamic condition objectives are described in Table I and objective environmental conditions in Table II. These are representative conditions and not firm requirements. It is desired that the physical profile be kept as small as possible for covertness and transportability. The system shall include an antenna that is steered electronically, mechanically, or via some hybrid solution set, along with the associated positioner/controller technology, sensor packages, radome, LNA and HPA. Transmit and receive shall be accomplished with a single aperture. The system should provide for full azimuth coverage and elevation coverage from zenith to at least the horizon without any keyhole effect. The antenna should acquire and remained locked on the Wideband Gapfiller Satellite (WGS) o r other satellite while providing a continuously usable signal when the vehicle is on the pause and move. Should the antenna drop lock, it should automatically reacquire the signal with no operator intervention. The objective antenna will operate over th e Ka uplink range of 30-31GHz, Q band uplink range of 43.5-45.5 GHz and K band downlink range of 20.2-21.2 GHz. The antenna will transmit in the right-hand circular polarization mode at Q band, right or left hand circular polarization at Ka band and recei ve in the left-or right hand circular polarization mode. The following combinations of transmitting and receiving polarization will be accomplished, but not simultaneously: Transmit RH and Receive LH; Transmit LH and Receive RH for K/Ka Band operation on ly. Q/K-band operation utilizes RHCP Transmit and RHCP Receive operation only. We are interested in what data rates the various antenna solutions would support for both on the move (OTM) and on the pause operation. In addition to satellite and UAV communications, line of sight terrestrial communications also needs to be supported. The Government envisions a separate antenna would support this purpose, however industry's perspective is solicited. This would require tracking at the horizon or lower. Nominal RF values by Application Type are given in table IV. Estimated Throughp ut capabilities required are given in Table V. These are estimates only. The contractor is required to provide link budget information ref Table III), including all conditions and assumptions, to support their chosen antenna size and throughput. Interested parties should submit white papers that shall include, but are not limited to the following information: link budget, performance data (to include size, weight and power consumption estimates), configuration drawings or illustrations, mounting concept, discussion of design maturity and remaining development, technical and schedule risk assessment, estimated development and unit costs (@100 ea quantities). For link budgets submissions, calculations should use the below Government Propagation mode l. White papers must be received no later than 4:00 PM, 30 September 2004, at HQ USA CERDEC, Attn: AMSRD-CER-ST-SS-TA (Louis Coryell), Ft. Monmouth, New Jersey 07703-5203.
