Trimble introduced Monday a new embedded Global Positioning System (GPS) receiver for timing applications-the Resolution T receiver.

With major advancements in performance, ease of integration, and software flexibility, the Resolution T receiver enables system integrators to add precise GPS or Universal Time Coordinate (UTC) time and synchronization to many products where cost or size had previously been a limitation.

The Resolution T receiver will be showcased at the Precise Time and Time Interval (PTTI) show in Washington, D.C.

Precise timing and synchronization is vital to today's wireless infrastructure, efficiently controlling the flow of network information data to maximize the use of bandwidth.

Backed by Trimble's more than 20 years of experience, innovation, and long-term commitment to the market, the Resolution T provides a low-cost, easy to use, highly accurate and reliable GPS timing source for the telecommunications, broadcast synchronization, power transmission and wireless industries.

Prior to the Resolution T receiver, many timing applications used smart antennas for system synchronization. The small, 3.3 volt receiver now enables integrators to embed precise GPS timing in their actual application.

Timing features of the Resolution T receiver include: Automatic Self-Survey to ensure accurate reference position for improved timing accuracy; the Overdetermined Timing Mode provides an extremely accurate 1 PPS synchronized to GPS/UTC better than 15 nanoseconds (one sigma); Timing Receiver Autonomous Integrity Monitoring (TRAIM) to assure high PPS integrity in Overdetermined Timing Mode; and other features. The modular design also allows for reduced integration time and low implementation risk.

In addition, Trimble's Resolution T receiver can greatly increase network security. Implementation completely inside the network firewall allows for an independent, traceable and dependable GPS timing and synchronization source for the ultimate in network security without an Internet connection.

The Resolution T receiver uses a general purpose Digital Signal Processor (DSP) in lieu of a custom GPS chip to provide a true software GPS receiver. This allows for extremely flexible software since the receiver is no longer restricted by hardware design.

The timing receiver is a complete all-in-view, 12-channel, parallel tracking GPS receiver designed to operate with the L1 frequency, standard position service, Coarse Acquisition mode.

Trimble's developer's kits include: the Resolution T GPS receiver mounted on an interface board in a durable metal enclosure, an active, external 5Vdc Bullet antenna, 50 feet of RG-59 cable, AC/DC power adapter, a starter kit enclosure including a motherboard that provides serial output, and a serial interface cable.

A reference manual and monitor programs are provided on CD-ROM. The Resolution T receiver uses Trimble Standard Interface Protocol (TSIP) or NMEA.

The Resolution T receiver and developers kit is expected to be available in late December 2004 through Trimble's worldwide Component Technologies sales organization.

Garmin Certifies TAWS For The GNS 530 And GPS 500

Olathe KS (SPX) Dec 06, 2004
Garmin announced last Thursday that the company has received FAA certification to add TSO C151b Class-B Terrain Awareness and Warning System (TAWS) functionality to the GNS 530 and GPS 500. This certification enables the Garmin 500 series of panel-mount avionics to provide the pilot with graphical and audible alerts of potential terrain and obstacle conflicts along the flight path.
