Policy directive on GPS issued in closing days of Trump administration

Space Policy Directive-7 highlights the United States’ ever growing dependence on space-based positioning, navigation and timing.

WASHINGTON — The Trump administration on Jan. 15 issued a policy memo focused on the United States’ dependence on the Global Positioning System and the need to prepare for a day when GPS might not be available. 

A constellation of 31 GPS satellites operated by the U.S. Space Force use radio navigation to provide positioning, navigation and timing information to military and civilian users worldwide. Satellites in space rely on GPS for navigation, attitude control, space situational awareness and new science applications such as radio occultation. 

Space Policy Directive-7 highlights the United States’ ever growing dependence on space-based positioning, navigation and timing. It suggests government and commercial organizations should have access to backup PNT technologies as GPS signals are likely to be disrupted. SPD-7 repeats many of the points and recommendations made by Trump in a February 2020 executive order. 

The increasing reliance on GPS for military, civil and commercial applications makes the system vulnerable, says SPD-7. “GPS users must plan for potential signal loss and take reasonable steps to verify or authenticate the integrity of the received GPS data and ranging signal, especially in applications where even small degradations can result in loss of life.”

SPD-7 says the United States “encourages the development of alternative approaches to PNT services and security that can incorporate new technologies and services as they are developed, such as quantum sensing, relative navigation and private or publicly owned and operated alternative PNT services.”

The policy says the United States supports the use of foreign satellite-based PNT services to supplement GPS. The integration of new services can improve accuracy, availability and resilience, says SPD-7. However, the U.S. government “does not assure the reliability or authenticity of foreign PNT services,” the policy says. “Receiver manufacturers should continue to improve security, integrity and resilience in the face of growing cyber threats.”

SPD-7 came out just hours after Vice President Mike Pence — who was chairman of the National Space Council for the four years of the Trump presidency — issued a report highlighting the council’s impact in civil and national security space activities.

ÉireComposites to create satellite optical instrument for ESA

ÉireComposites has announced an agreement with the Belgian company, OIP Sensor Systems to design and produce stray light baffles, which will form part of the European Space Agency’s ALTIUS satellite.

The baffles will be the first external part and largest functioning piece of equipment ever to be manufactured in Ireland and launched into space.

The stray light baffles will prevent out-of-field stray light from reaching the lenses of the satellite’s optical instruments; instead, a system with periscope mirrors will be used to align the light. Stray light baffles rely upon highly controlled and precise manufacturing and finishing. ÉireComposites will manufacture the three baffles that will be attached to the side of the satellite to assist with the mission objective.

OIP forms part of a consortium that signed the contract with the European Space Agency to build this satellite which is expected to be launched by end of 2023 from French Guiana. The mission will deliver profiles of the stratospheric ozone, as well as profiles of other atmospheric trace gases. This will provide scientific understanding on how the rise in greenhouse gases affects the atmosphere.

Tomás Flanagan, ÉireComposites CEO said: “The ALTIUS satellite will signal a major milestone for Irish participation in space exploration as the three stray light baffles will become the first optical instruments manufactured in Ireland and the largest satellite parts manufactured in this country. This is a massive achievement for the company and I hope this will be the first of many parts we manufacture for space exploration missions.”

“The ALTIUS mission will play a substantial role in how we look at climate change and the impact it has on Earth. The mission will allow for long-term monitoring and scientific study of the protective ozone layer which covers Earth and inform decisions around climate change. I am excited that we will be part of this research and I would like to take the opportunity to commend the team here in Inverin that have contributed to our success in obtaining this contract.”
