In MarAd Budget

For Ship Repair

A House subcommittee recently added $189 million to the Maritime

Administration's Fiscal Year 1993 budget for ship maintenance and repair for the Ready Reserve Force (RRF). Additionally, an amendment was introduced authorizing $35 mil- lion for vessel construction loan guarantee commitments.

Members of the Merchant Ma- rine Subcommittee of the House

Merchant Marine and Fisheries

Committee recently approved a $727 million FY '93 budget for MarAd beginning this October.

The subcommittee justified the additional funding for ship mainte- nance based on the "lessons learned" during the Gulf War.

Rep. Walter B. Jones (Dem.-NC), chairman of the subcommittee, and

Rep. Norman Lent (Rep.-NY), jointly introduced the amendment authorizing $35 million for MarAd's

Title XI ship financing program. The $35 million for loan guarantee com- mitments, according to MarAd, will enable the agency to issue guaran- tees for about $750 million for the construction or reconstruction of

U.S.-flag ships in U.S. shipyards.

Harris Paper Analyzes

Transmitter Interference

In Warship Installations

Harris Corporation's RF Commu- nications Group, ofRochester, N.Y., has recently released a White Paper analyzing the warship design prob- lem of overcoming mutual interfer- ence among multiple transmitters and receivers without a trade-off in system performance.

Entitled Broadband Solutions to

Mutual Interference in Collocated

Shipboard Radio Installations, the paper discusses the operational re- quirements for HF radio systems in a modern battle group and the re- sulting need for multiple radio sys- tems in a collocated environment. It analyzes the techniques currently being used to address the require- ment and describes a new approach to broadband radio architecture, which overcomes the drawbacks in- herent in conventional narrowband systems and broadband powerbank systems.

The paper presents test data, which show substantial reduction in wideband intermodulation (IM) distortion using this approach.

The Royal Canadian Navy is cur- rently testing these new-generation broadband HF systems onboard the lead ship of its new patrol frigate class, HMCS Halifax, with promis- ing results, according to Harris.

Going round In circles.

SeaLand moves millions of tons of cargo from the West

Coast of the U.S. to the Far

East. For them, Trimble GPS is the best way to find the exact great circle routes that will save both fuel and time.

The Leader in GPS Technology

Good for the long haul.

American President Lines, one of the largest shipping lines in the world, outfitted their latest container ships with Trimble

GPS. These systems can store preprogrammed lists of way- points for their frequently travelled routes. With GPS accuracy, they hold truer courses, stay on tighter sched- ules, and save tons of fuel.

Inside/Outside with GPS.

Crowley Maritime is stan- dardizing on Trimble GPS.

Inside tugs working Puget

Sound rely on Trimble accuracy to thread their way through rocky passages.

Outside boats, working along the Alaskan coast and throughout the world, use

GPS to stay on schedule, even in the worst weather.

Small box, big reputation.

The Navy used the military version of our portable

TransPak II to locate mines in the Persian

Gulf. According to one Navy commander, it "allowed a success at mine bunting never previously experienced." Closer to home, you can use it in a tender or as a back-up unit.

Ultimate Accuracy. For ultra-precise navigation, a technique called "Differential

GPS" can give you 2-5 meter accuracy. Soon coastlines will be dotted with radio beacons like the one at Montauk N. Y., broadcasting corrections to

GPS receivers in the area.

Only Trimble products come standard with the ability to accept these corrections.
