Block-II-IIA-O

Boeing and the U.S. Air Force have signed a GPS sustainment agreement to ensure the health of current satellites on orbit. The agreement enables persistent GPS capability for civilians and the military as Boeing works on next-generation GPS satellites. Under the agreement, Boeing will support GPS IIA and IIF satellites on orbit for the next five years. Boeing, which has been... read more

New system designed to protect avionics from GPS jamming

January 31, 2017By
Anti-GPS jamming system (ADA) by Israel Aerospace Industries.

Israel Aerospace Industries (IAI) has unveiled ADA — an advanced system that protects avionic systems from GPS jamming. ADA has already been integrated into several systems and platforms operating both in Israel and abroad. The system recently won a tender from Israel’s Ministry of Defense for integration into one of the main platforms of the Israel Air Force. ADA was developed... read more

Interference mitigated with CRP and dual-polarized antennas: Free webinar

January 30, 2017By
February cover story.

Two new topic areas and presentations have been added to this Thursday’s free webinar on Signal Interference: Detection and Mitigation. The speakers will explore anti-jamming protection with controlled radiation pattern antennas (CRPAs) and with dual-polarized antennas. The latter topic is also the cover story for the February issue, which demonstrated a significant improvement in positioning accuracy and robustness against interference... read more

GPS data release to boost space-weather science

This configuration shows the orbits just before the start of this solar cycle’s biggest geomagnetic storm, which occurred on March 17, 2015. The darkest orbital lines indicate the position of the satellites in that moment; the lightest lines indicate where they were 12 hours prior.

Today, more than 16 years of space-weather data is publicly available for the first time in history. The data comes from space-weather sensors on board the nation’s GPS satellites. The newly available data gives researchers a treasure trove of measurements they can use to better understand how space weather works and how best to protect critical infrastructure, such as the... read more

Iridium Communications Inc. has successfully launched its first 10 Iridium NEXT satellites, which will support real-time automatic dependent surveillance broadcast (ADS-B) operations in oceanic regions. Iridium NEXT is the company’s next-generation satellite constellation, replacing and enhancing its existing network of low-Earth orbit satellites spanning the entire globe — the largest commercial satellite constellation in space. The satellites were delivered into low-Earth orbit an hour after... read more

GNSS Pest Control
A new solution for GNSS multipath employs a multi-element antenna with RF signal switching and a single front end to reduce complexity, power consumption and cost. Correlator beamforming, initially used in the 2.4 GHz frequency band where it has proven effective at mitigating multipath in heavy industrial environments, has been successfully adapted for GNSS use. read more
