Trimble Mini-T

Introduction

The Trimble Mini-T™ takes GPS disciplined clocks to a new level of integration that provides a simple, cost effective and high performance solution in Trimble's smallest form factor to date. The Mini-T gives OEMs the opportunity to embed a low-cost precise time and frequency reference, in Trimble's smallest form-factor yet. Trimble created the Mini-T using clock technology proven in generations of deployed units used in CDMA, WLL, WiMAX, and broadcasting applications. It utilizes the latest in GPS technology, combined with a precision ovenized oscillator for near - atomic clock precision timing.

Ease Of Integration & Use

The Mini-T eliminates the need for expensive rack-mount timing boards, because you can embed the Mini-T on your board to save space and power. Trimble integrates the GPS and timing circuitry all on a single board - no extra GPS daughter board means that Trimble offers a lower part count, resulting in higher reliability and lower cost.

On power-up, the Mini-T performs a self-survey automatically, and only one satellite is required for on-going operation. Timing Superpackets™ offer the user all of the timing information required by the host application, in an easy-to-use format. The Trimble proprietary Time-Receiver Autonomous Integrity Monitoring (T-RAIM) carefully validates the satellite signals, ignoring inaccurate information that could interfere with the precision outputs.

The Mini-T is ready to use out of the box for most applications. When the oscillator has warmed up and a single satellite is accessed for GPS data, the Mini-T outputs 1 PPS and a reference frequency. It then begins a self-survey mode, which allows use of an overdetermined time solution.

Proven reliability

Trimble has deployed tens of thousands of GPS clocks into the field over the last decade, which continue to perform year after year. The Mini-T offers proven reliability and performance will exceed your expectations, and enable you to provide your customers with the highest quality GPS solution available today. The Mini-T GPS Clock is offered with a standard 10MHz output, but it is also available in custom frequencies. A starter kit is also available for customer evaluations (see below).

DSP Approach

Unlike previous models which used conventional ASICs, this new module (like the Resolution T) implements the satellite receiver functionality using a commercially available, general purpose Digital Signal Processor (DSP). Due to this flexibility, this product will be upgradeable in the field to Galileo L1 compatibility when the code structure becomes available. The Mini-T timing receiver was implemented to test the technical feasibility and the cost effectiveness of the flexible DSP approach.

Starter Kit

A starter kit is available from DPIE for the Mini-T. It consists of the following items:

• Mini-T mounted to a plexiglass enclosure
• 5V DC Bullet Antenna
• 75 foot interface cable
• All required cables/adapters (inc PSU)
• CD (inc user guide and software tool).

Note - the starter kit is not CE marked.
