  • Fiber Optic Antenna Link OFW-5800 GPS
    The OFW - 5800/GPS is a "Next Generation" Global Positioning System (GPS) Fiber Optic Antenna Link (FOAL) subsystem that is a designed to operate in the Naval shipboard environment. The OFW - 5800/GPS FOAL subsystem consists of four independent RF to Fiber antenna headend units, that can
  • GPS Data Collection for Marine Navigation Research
    Step 1 is to capture one channel analog signal at 40 MS/s or more for less than 10seconds. The signal comes from an antenna and RF down converter module.
  • Integrated Low Noise Multi-Chip Amplifier Modules
    To amplify weak signals received by the antenna in communication systems, low noise amplifiers (LNAs) are deployed. LNAs are used in various applications, for example in, GPS receivers, wireless data systems, satellite communication, cellular handsets, radio systems, etc. The low noise
  • Giving brains to off-highway brawn
    GPS equipment and innovative power sources are at the top of Caterpillar's wish list. Group Caterpillar Inc. Peoria, Ill. The AccuGrade system uses several global positioning systems and a computer that derives guidance information and delivers it to the cabs of off-highway equipment. Inside
  • Low Noise Amplifier Design Methodology Summary
    Low Noise Amplifiers (LNAs) amplify weak signals received by the antenna in communication systems. Every wireless system module typically consists of one or several LNAs. Applications include GPS receivers,. wireless data systems, satellite communication, cellular handsets, radio systems, etc
  • Tight seals for the long haul
    on sensitive components for GPS antennas, cell phones, and communication modules. Windshield-wiper motors, backup sensors, and fluid reservoirs also must be sealed tightly from water. Proper seal and gasket selection, however, involves more than looking at how a material resists water. Tests reveal
  • Uncle Sam to mobile robot makers: Don't reinvent the wheel
    with such options as a 15-ft telescoping mast, 2D laser rangefinder, 24-GHz radars, differential GPS, and FLIR cameras. Possible payloads include weapon modules, manual drive-by-wire, damage control, storage, and fuel. On the Tags-CX, JAUS promotes plug-and-play with a standard interface
  • Mobile monitor rides the rails to track defects
    sensor for measuring changes in the distance between the rails. A GPS receiver is built into the operator panel. A linear encoder in one of the surf bars records signals from a magnetic wheel that serves as a distance sensor while the device moves down a track. The RailSurf processor uses five
