The fifth satellite in the Indian Regional Navigation Satellite System (IRNSS) constellation is ready for lift-off. IRNSS-1E will launch at 0401 GMT Wednesday (11:01 p.m. EST Tuesday) from Satish Dhawan Space Center on Sriharikota Island, on India’s east coast. As in the previous four launches of IRNSS satellites, the navigation satellite will ride aboard a Polar Satellite Launch Vehicle (PSLV). This is the... read more

Advocacy in the U.S. capital urges augmentation of GPS/GNSS with eLoran and other “complementary terrestrial PNT services to increase resilience.” See the Resilient Navigation and Timing Foundation’s website, rntfnd.org. This is assuredly a good thing, a worthy cause. I’ve come to believe, however, that true resilience goes beyond what we normally think of as position and timing sensors. Stimulus comes... read more
