eLoran: The Never-Ending Story?

Loran tower – Starkey Loran research photos 2001

To say that enhanced Loran (eLoran) has been an on-again off-again program would give short shrift to multiple generations of official ambivalence about the proposed backup for GPS.

The latest chapter began on June 4 when Senator Maria Cantwell (D-Washington) introduced S. 1194, the Coast Guard Authorization Act for Fiscal Years 2010 and 2011 (FY2010/11).

Among other details, the measure directs the Secretary of Transportation to continue the Loran system until a plan has been drawn up and implemented to transition the program to eLoran.

These include an integrated display for manual or automated machine operation, a variable rate application (VRA) option for the company’s lightbar guidance system, and two new differential GPS receivers.

The AgGPS FmX integrated display can operate as either a stand-alone manual guidance system or as part of an automated guidance, implement control or steering system. The FmX touch screen display is 12.1 inches, approximately 35 percent larger than the industry standard 10.4-inch screen, yet the display requires no more space in the cab than its predecessor, the AgGPS FieldManager, according to the company.

Thales Alenia Space Italia Wins Two Galileo Receiver Development Contracts

The European Space Agency (ESA) has awarded Thales Alenia Space Italia (TAS-Italia) two contracts for development of Galileo ground station receiver equipment.

One contract is for Galileo In-Orbit Validation Element (GIOVE) phase A/B ground station receivers capable of tracking the multiplex binary offset carrier (MBOC) signal that is common to both the Galileo Open Service (OS) and the new GPS L1 civil signal, which will be transmitted beginning with the GPS III generation of satellites.
