All of the information may be isplayed in large or small figures; irthermore, shown in the right- and section of the display is the osition of the ship in longitude and ititude, or alternatively the dis- ince traveled in total miles and aily miles. When NAVIDATA is used in com- ination with C .Plath autopilots and >g systems, all that is additionally squired is the longitude and lati- ide information in the NMEA 0183 irmat from a GPS receiver. Automatic chart plotters AVIPLOT I/S (position display ily) and NAVIPLOT I/SR (posi- on display, route planning, steer- ig interface to an autopilot) are sed in the indication of ship's posi- on. NAVIPLOT I/S can be retrofit- id to existing vessels. The main ivantages are: accepts all charts L Mercator and plane projection; ores chart data for more than 000 charts; continually indicates vnship's position by means of a jht-point; dead reckoning func- an via inputs for speed and head- g; and joystick operation. NAVIPLOT I/SR provides all of e above features, as well as: route anning; route steering and route ntrol; and storage capacity for )0 routes, each with 250 aypoints.

The five Inmarsat-3 satellites, ing manufactured by Martin arietta Astro Space, will enable marsat to use the increased power d capacity of spot-beam technol- y to provide service to the grow- 1 number of mobile communica- ns users worldwide and to re- October, 1994 78 duce the size, weight and cost of mobile terminals. The Inmarsat-3 satellites are more than eight times more powerful than the second generation Inmarsat-2s currently in service. This additional power will make it possible not only for users to communicate via smaller and cheaper mobile terminals, but will also possibly result in an even- tual decrease in user charges.

The TANS Vector consists of four GPS antennas and a receiver pro- cessor unit. It features solid-state electronics — a technology report- edly not subject to heading drift — and provides waypoint navigation. TANS Vector can operate in accu- rate differential mode and can serve as a stand-alone attitude sensor. It can also be integrated into gy- roscope or inertial navigation sys- tems.
