TAGS Features and Specifications

For a complete list of applications, specifications, and example data, please download a pdf version of the TAGS brochure here.

Hardware Features

  • The Air III has solid-state Fiber-Optic Gyros (FOGs) enabling the highest sensitivity possible using direct digital ouput.
  • Enhanced digital control system records data and monitors system performance with greater reliability.
  • DSP Platform Control using a digital signal processor board to keep the platform level independently of the system computer, allowing higher platform gain which gives faster response times and smaller errors.
  • Laboratory tests show a dynamic repeatability of better than 0.25 millGals.
  • Increased precision via 1000 Hz internal sampling which avoids aliasing, and produces 21bit effective resolution.
  • Employs industrial-grade electronics designed for long life and high reliability even in adverse conditions.
  • Uninterruptable Power Supply (UPS) is standard on all systems.
  • Aircraft inverter (28VDC to 100VAC) included with all systems.
  • Spring Tension Encoder sotres value in permanent memory.
  • Integrated GPS and Rubidium oscillator provides stable time base and precision sampling.
  • Full customer support:
    • Installation, training, survey set up, and assistance
    • Fully modular spare electronics plug-ins for less downtime
    • On call technical support.
