With a mission to power the current and next-generation of GPS-enabled products and systems, XONA Space Systems keeps the mantra ‘precision, power and protection’ in all that it does as this 2020-start-up designs, builds and launches its fleet of low earth orbit satellites. We spoke with XONA CEO Brian Manning for his insights on how this could impact the maritime, offshore energy and subsea sectors.The following was excerpted from Maritime Reporter TV’s interview with XONA CEO Brian Manning.

Don’t let the titanium metal walls or the sapphire windows fool you. It’s what’s on the inside of this small, curious device that could someday kick off a new era of navigation.For more than a year, the avocado-sized vacuum chamber has contained a cloud of atoms at the right conditions for precise navigational measurements. It is the first device that is small, energy-efficient and reliable enough to potentially move quantum sensors — sensors that use quantum mechanics to outperform conventional technologies — from the lab into commercial use…

The Global Positioning System (GPS) has become vital to the maritime community. Proper use of properly functioning equipment can allow ships to safely navigate worldwide. It’s signals are now integrated into a variety of shipboard items, including the automatic identification system (AIS) and the electronic chart display and information system (ECDIS). It has been copied by Russia’s GLONASS, Europe’s GALILEO, China’s BeiDou, India’s IRNSS, and Japan’s QZSS. Originally developed for the US Navy for ship positioning and navigation…

Maritime GPS Users, Remember 6 April 2019

Maritime users of the Global Positioning System Standard Positioning Service (GPS-SPS) are urged to check their systems ahead of the week counter roll over on 6 April 2019, informed  International Maritime Organization (IMO).Some outdated GPS receiver systems may cease to function properly - with potentially serious impacts on navigation, the UN body pointed out.The roll over occurs because the GPS system transmits time to GPS receivers using a format of time and weeks as a 10-bit value, which started from 6 January 1980, and can only count 1023 weeks.The previous roll over was on 21 August 1999, when systems reset and began counting towards week 1023 again.
