U.S. tracks military M-code GPS signal
From: UPI
EL SEGUNDO, Calif., Nov. 6 (UPI) -- Engineers have for the first time acquired and tracked the new U.S. M-code military Global Positioning System signal from an orbiting satellite.
Raytheon engineers in southern California picked up the signal that is designed to provide next-generation GPS data that is more difficult to jam than current GPS, the company announced Monday.
"This initial success demonstrating the ability of our next-generation receivers to track the new modernized GPS signal is a key step forward for our Modern User Equipment program," said Raytheon's Ralph Garcia.
The Modern User Equipment project is working toward a new generation of GPS receivers as the U.S. military migrates toward weapons and networking systems that include a GPS element. Raytheon received a $38 million contract this summer to develop an M-code receiver card.
M-code is a keystone of the advanced system. It is designed to be transmitted on both the satellite L1 and L2 bands and extends out to 24 Megahertz, compared to 20 MHz for the Y code.
The result is a greater anti-jamming capability as well as better accuracy and encryption, Raytheon said
The M-code began transmitting recently from the new GPS Block IIR-14 (M) satellite that has been in orbit for nearly a year. The spacecraft has been transmitting legacy signals while ground crews prepared for the recent M-code test.
