US Maritime Advisory – GPS Interference

Approximate locations are on the map here; instances where there are (1) or more reports are represented by only (1) red dot on the map.

Towards the end of September the US Maritime Administration (MARAD) issued an advisory notice (No 2020-016) concerning GPS interference.

Multiple instances of significant GPS interference have been reported worldwide in the maritime domain. This interference is resulting in lost or inaccurate GPS signals affecting bridge navigation, GPS-based timing, and communications equipment. Satellite communications equipment may also be impacted.

Over the last year, areas from which multiple instances have been reported include the eastern and central Mediterranean Sea, the Persian Gulf, and multiple Chinese ports. The US Transportation Command “Message for Industry” at https://go.usa.gov/xdSpq provides additional GPS interference information.


ESA Discovery studies lay path to navigating the Moon

GPS satellites – like those of Galileo, Russia’s Glonass or their Japanese, Chinese and Indian counterparts – aim their antennas directly at Earth. Any satellite orbiting above the GPS constellation can only hope to detect signals from over Earth’s far side, but the majority are blocked by the planet. For a position fix, a satnav receiver requires a minimum of four satellites to be visible, but this is most of the time not possible if based solely on front-facing signals. Instead, GIOVE-A has been able to make use of signals emitted sideways from GPS antennas, within what is known as ‘side lobes’. Just like a flashlight, radio antennas shine energy to the side as well as directly forward. – © ESA

Just as we navigate our way around Earth’s surface using the connection between our phones and navigation satellites high above us, our missions use the very same satellites to navigate their way in space.

Around ten years ago, engineers started demonstrating that spacecraft outside the orbit of navigation satellites could also navigate in space using ‘spill over’ signal from the satellites.

ESA has invested in the development of an appropriate receiver, and is exploring whether it could be demonstrated on the Lunar Pathfinder mission. It will help lay the groundwork for providing navigation services around the Moon, currently studied through two ESA NAVISP activities and culminating in the Moonlight initiative.

400,000 seafarers stuck at sea as crew change crisis deepens

Some 400,000 seafarers from across the globe are now stranded on ships, continuing to work but unable to be relieved, in a deepening crew change crisis which threatens trade and maritime safety.

During a high-level event on the margins of the United Nations General Assembly (24 September), Captain Hedi Marzougui, who was in command of a vessel between December 2019 and May 2020, appealed to Governments to act to allow seafarers to come home: “Not knowing when or if we will be returning home brings a severe mental toll on my crew and myself,” Captain Marzougui said. “I would encourage each and every one of you to think of how you would feel, if you had to work every day, for 12 hours, with no weekends, without seeing your loved ones, and trapped at sea. Now add that you have to do that with no idea of when you will be repatriated.”


UK Government to explore new ways of delivering satnav for the UK

New options for a UK satellite navigation and timing capability programme to support the nation’s critical infrastructure will be explored by the government.

The Space-Based Positioning Navigation and Timing Programme (SBPP) will explore new and alternative ways that could be used to deliver vital satellite navigation services to the United Kingdom which are critical for the functioning of transport systems, energy networks, mobile communications and national security and defence, whilst boosting the British space industry and developing the UK’s own capabilities in these services.

This will follow the work of the UK’s Global Navigation Satellite System (UK GNSS) programme, which is due to conclude at the end of the month.

Satellite navigation is precise, reliable and available continuously around the globe, but overreliance on it presents a clear and present danger to the smooth passage of maritime trade, concludes a major ESA-backed study.

“The aim of our Maritime Resilience and Integrity in Navigation, MarRINav, project, was to peer 10 years ahead to see if the needs of mariners for accurate, resilient PNT, would continue to be fulfilled.” according to Jonathan Turner of ‘blue economy’ specialist NLA International, which led the study for ESA.

What the MarRINav team found was that the very success of satellite navigation, in terms of its precision, reliability and always-on availability, is a cause for concern.

A Guide to Bulk Carrier Operations

There is no doubt that bulk carriers are some of the workhorses of international maritime trade. Those responsible for operating them need to manage significant risks inherent to the dry bulk trade. Certain cargoes can deplete oxygen, catch fire, explode, corrode holds or simply deteriorate. At terminals, the Master may come under pressure to accept cargoes that are too hot or wet, which could endanger vessel and crew.

In recent years the dry bulk sector has made huge efforts to improve safety, but to quote Intercargo Secretary General Dr Kostas Gkonis: ‘…there is no room for complacency and more work is needed.’

With the support of Intercargo and vetting organisation RightShip, The Nautical Institute has responded by publishing A Guide to Bulk Carrier Operations.

Galileo next-gen satellites on the horizon

Galileo satellites are placed in medium orbits, at 23,222 km altitude along three orbital planes so that a minimum of four satellites will be visible to user receivers at any point on Earth once the constellation is complete. The fifth and sixth Galileo satellites, launched together on 22 August 2014, ended up in an elongated orbit travelling out to 25,900 km above Earth and back down to 13,713 km. In addition, the orbits are angled relative to the equator less than originally planned. – © ESA-P. Carril

Following the European Commission’s decision to accelerate development of Galileo Next Generation, ESA has asked European satellite manufacturers to submit bids for the first batch of the Galileo Second Generation (G2) satellites. The new spacecraft are expected to be launched in about four years.

The next-generation satellites will provide all the services and capabilities of the current first generation, together with a substantial number of improvements as well as new services and capabilities.
