T e x a s Instruments Unveils N e w Loran C N a v i g a t or — L i t e r a t u r e A v a i l a b le

Texas Instruments recently introduced the TI 9900 II Loran C navigator, a complete Loran Cbased navigation system with the performance, features, and accuracy of the popular TI 9900, plus an exceptional array of additional capabilities.

The TI 9900 II features 100 waypoints that can be entered as time differences or latitude/longitude coordinates. Trips of up to 50 legs can be stored, with reverse capabilities.

A unique trip planning function allows the user to compute course and distance between any two waypoints without receiving a Loran signal. Additional capabilities of the system include automatic waypoint sequencing and the display of range and bearing to the next waypoint as each one is passed.

According to Gary Howe, TI marine marketing manager, "The TI 9900 II has been designed with the user in mind. A sealed, fully backlit keyboard is provided, with oversized keys, not a membrane key pad. This makes entering information fast, sure, and easy, even with gloves on." In addition, most of the TI 9900 II navigation functions—range to destination, course-over-bottom, cross track error, speed-over-bottom, time-to-go, ETA, velocitymade- good, magnetic variation, and many more—can be instantly displayed with only one simple keypress.

A large, clear alphanumeric dot matrix display provides navigation navigation information in plain, easyto- read English, eliminating confusion caused by similar-looking letters and numbers, such as "b" and "6." Six highly advanced, electronic notch filters are built into the TI 9900 II, providing precise protection from signal interference no matter where the vessel is operated.

The feature-oriented unit also includes three separate alarm systems for safer navigation.
