The company manufactures products for recreational and commercial marine markets, and is a major supplier to the U.S. military of digital compass systems for ships and armored vehicles. I NASA had developed an experimental, micropro- 1 cessor-controlled satellite antenna for motorists to send and receive phone, fax and other telecommunications as part of the Advanced Communications Technology , Satellite (ACTS) program. Tests proved that sensors a within the unit kept the antenna continually pointed at the ACTS positioned in space. JPL had developed the tracking antenna system for use on ACTS which can handle digital television signals in the Ka-band frequency from a mobile or parked vehicle. Through the Technology Affiliates Program at JPL, the ACTS antenna system was transferred from experi- mental testing status to commercial development at KVH. I The ACTS design enables mobile satellite antennas / to remain pointed at the satellite, regardless of the motion or vibration of the vehicle on which it is mounted. This design permits a satellite antenna to smoothly lock onto the desired satellite signal, without encountering aiming fluctuations. Changes in aiming are a common drawback in other land-mobile satellite communication antennas. Successful tests had shown the ACTS antenna ideal for many applications, including: KVHIndwhy'es, Inc. 5 sateIIite antenna improves communication one-way transmission of patient data from field on marine or mobile land smmportation, sllch as trucks, buses, and I paramedics to the base hospital; trains.
