The SATELLITE conference and exhibition brought together about 12,000 satellite professionals across all facets of the satellite community, including the mobility, military, broadcast, maritime and enterprise markets. The event took place March 10-13 in the Washington DC convention center which is a very good location given its close ties to the Aerospace and Defense industry. There are more than 350 exhibitors ranging from the large OEMs like Boeing, Lockheed Martin, Harris, SES, Intelsat, etc. to the antenna/dish manufacturers to component and test providers from the RF/microwave industry.
Some of the popular topics are IP networking over satellite, interference avoidance, satellite broadband services, UAV satellite communications among others. Ka-band is the newer frequency band that is being implemented for higher capacity although various frequency bands do have other advantages. Almost everyone we met with was featuring new Ka-Band components and systems.
Traditionally, the RF and microwave companies we have seen at Satellite are the antenna, cable, filter and amplifier companies plus the test and measurement companies, but there seems to be more general component and sub-assembly companies exhibiting each year. Here is our round up of the offerings we can across at this year’s event in the exhibition:
Agilent was showing off a variety of test equipment for satellite applications including their FieldFox handheld units, oscilloscopes and SystemVue software. From guidance systems to satellite payloads to microwave communications, design and validation tools from Agilent provide excellent assurance that the satellite and its subsystems will work the first time, every time for the duration of the mission using their test equipment. Agilent, soon to be Keysight Technologies, was sporting their new logo and red shirts - the first time I have seen the new look at a show.
Anritsu announced its MS2830A Spectrum Analyzer/Signal Analyzer is now compatible with the Monics satellite carrier monitoring system from SAT Corporation (SAT), a subsidiary of Kratos Defense & Security Solutions, Inc.
