Magnavox Introduces (continued) cessive 1.6 second position compu- tations. Real-time set and drift in- formation is also displayed using the vector difference between COGs and SOGs, and the ship's measured speed and heading through the water.

The system has a two-channel receiver, for continuous GPS usage.

While the first channel sequentially tracks each selected satellite, the second searches for and selects fu- ture optimum satellites.

The Magnavox approach empha- sizes maximum availability. To op- timize the GPS use with the pres- ently limited constellation, the MX 1100-GPS can provide two-satellite navigation, delivering a more pre- cise continuous running fix. This technique minimizes the accumula- tion of dead reckoning error be- tween either three-satellite GPS or

Transit fixes.

Magnavox has designed these re- ceivers for optimum navigation per- formance today and for a smooth transition to the future. The MX 1100-GPS lets the owner continue working with the familiar Transit system while learning GPS. As more

GPS satellites are launched, the re- ceiver takes full advantage of the expanded constellation. Ultimately, and without operator intervention, the Magnavox system will navigate totally on GPS satellites using

Transit as a backup system. (The

Transit system will remain in opera- tion until at least 1994.)

The new SatNav series is avail- able in either of four models, includ- ing single and dual-channel Transit

Satellite and Omega capabilities. In addition, an upgrade package con- sisting of easily installed electronics boards and antenna is offered as a

GPS field retrofit for existing Mag- navox MX 1102, MX 1112, MX 1142, MX 1105, MX1107, and MX 1157 Transit SatNavs.
