COLUMBUS, Ohio (Ohio State University PR) — Engineering researchers have developed a method to use signals broadcast by Starlink internet service satellites to accurately locate a position here on Earth, much like GPS does. It is the first time the Starlink system has been harnessed by researchers outside SpaceX for navigation.
ROME (ASI PR) — Finding the best route for lunar orbit and easy parking on the Moon is the goal of NEIL (Navigation Early Investigation on Lunar surface) GNSS receiver with Software Defined Radio (SDR) technology. The creation of NEIL, named in honor of Neil Armstrong, the first man to touch the lunar soil, is at the center of an agreement between the Italian Space Agency (ASI) and NASA linked to the CLPS 19-D mission (NASA missions with contributions commercial and private of an experimental nature) with which the American space agency has planned to land with a lander in the Mare Crisium basin in 2023. [Editor’s Note: This is Firefly Aerospace’s Blue Ghost lander mission.]
NEIL, subject of the contract signed between ASI and the company Qascom SRL, is the on-board payload that will be an integral part of the experiment called Lunar GNSS Receiver Experiment (LuGRE), defined in the ASI/NASA agreement, which aims to develop an activity in a lunar and cislunar environment.
Designed to improve navigation for robotic explorers and the operation of GPS satellites, the technology demonstration reports a significant milestone.
PASADENA, Calif. (NASA PR) — Spacecraft that venture beyond our Moon rely on communication with ground stations on Earth to figure out where they are and where they’re going. NASA’s Deep Space Atomic Clock is working toward giving those far-flung explorers more autonomy when navigating. In a new paper published today in the journal Nature, the mission reports progress in their work to improve the ability of space-based atomic clocks to measure time consistently over long periods.
GREENBELT, Md. (NASA PR) — NASA has awarded a contract to the University of Michigan for the Cyclone Global Navigation Satellite System (CYGNSS) for mission operations and closeout. A constellation of eight microsatellites, the system can view storms more frequently and in a way traditional satellites are unable to, increasing scientists’ ability to understand and predict hurricanes.
MCLEAN, Va., June 24, 2021 (Iridium PR) – Iridium Communications Inc. (NASDAQ: IRDM) today announced it has been awarded a research and development contract worth up to $30 million by the United States Army (Army) to develop a payload to be hosted on small satellites that supports navigation systems, guidance and control for the global positioning system (GPS) and GPS-denied precision systems. The new experimental Iridium payload is intended to be hosted by another Low Earth Orbit (LEO) commercial satellite constellation, complementing the Iridium® constellation’s capabilities.
Through this contract the Army intends to develop this payload to support the concept of a rapidly deployable smallsat constellation to provide more effective sensor-to-soldier data transmission when in the field. The development of this new payload is based on Iridium Burst® technology, a unique service that can transmit data to millions of enabled devices at a time from space.
SpaceX dominated, China surged and Russia had another clean sheet as American astronauts flew from U.S. soil again in a year of firsts.
First in a series

Despite the COVID-19 pandemic, 2020 was a very busy launch year with a number of firsts in both human and robotic exploration. A total of 114 orbital launches were attempted, with 104 successes and 10 failures. It was the same number of launches that were conducted in 2018, with that year seeing 111 successes, two failures and one partial failure.
The Department of Defense (DOD) needs to improve its efforts at developing alternatives to the Global Positioning System (GPS), whose signals are vulnerable to being jammed by enemies, according to a new report from the Government Accountability Office (GAO). [Full Report]
LUXEMBOURG (European Court of Auditors PR) — The European Union has not done enough to harness the full potential of its space programmes, according to a special report published today by the European Court of Auditors (ECA). While the satellite-based programmes Galileo and Copernicus in particular provide valuable services and data, more efforts are needed to capitalise on the significant investment made (around €18 billion so far) and to optimise the benefits they bring to citizens and the economy. The auditors call for a comprehensive strategy, more targeted actions and better use of the regulatory framework for efficiently supporting the uptake of services.
MOSCOW (Roscosmos PR) — On March 20, a launch of the Soyuz-2 launch vehicle with the Fregat upper stage is scheduled from the Baikonur Cosmodrome that will deliver 38 spacecraft (SC) from 18 countries into three sun-synchronous orbits:
MELBOURNE, Fla. — L3Harris Technologies (NYSE:LHX) has received contracts totaling $137 million for four navigation payload Mission Data Units (MDU) for future GPS III Follow-on (GPS IIIF) satellites.
Lockheed Martin, the prime contractor for GPS III/IIIF, selected L3Harris in 2018 to design and build the first two fully-digital MDUs, the heart of the satellite’s navigation payload. The MDU generates more powerful GPS signals and assures clock operations for GPS users.

NASA is developing capabilities that will allow missions at high altitudes to take advantage of signals from Global Navigation Satellite System (GNSS) constellations — like GPS commonly used in the U.S. These signals — used on Earth for navigation and critical timing applications — could provide NASA’s Artemis missions to the Moon with reliable timing and navigation data. NASA’s Space Communications and Navigation (SCaN) program is developing the technologies that will support this goal.
SUBJECT: Space Policy Directive 7, The United States Space-Based Positioning, Navigation, and Timing Policy
This Space Policy Directive establishes implementation actions and guidance for United States space-based positioning, navigation, and timing (PNT) programs and activities for United States national and homeland security, civil, commercial, and scientific purposes. This policy complements the guidance set forth in Executive Order 13905 of February 12, 2020 (Strengthening National Resilience through Responsible Use of Positioning, Navigation, and Timing Services), and the intersector guidance for Global Navigation Satellite Systems (GNSS) included in the December 9, 2020, National Space Policy. This policy supersedes National Security Presidential Directive-39 (NSPD-39) of December 15, 2004 (United States Space-Based Positioning, Navigation, and Timing Policy).

The Artemis generation of lunar explorers will establish a sustained human presence on the Moon, prospecting for resources, making revolutionary discoveries, and proving technologies key to future deep space exploration.
To support these ambitions, NASA navigation engineers from the Space Communications and Navigation (SCaN) program are developing a navigation architecture that will provide accurate and robust Position, Navigation, and Timing (PNT) services for the Artemis missions. Global Navigation Satellite System (GNSS) signals will be one component of that architecture. GNSS use in high-Earth orbit and in lunar space will improve timing, enable precise and responsive maneuvers, reduce costs, and even allow for autonomous, onboard orbit and trajectory determination.
LOS ANGELES AIR FORCE BASE, Calif.–Global Positioning System III Space Vehicle (SV) 04 received United States Space Force’s Operational Acceptance approval on Dec. 1- marking yet another significant milestone for the GPS III program, Space and Missile Systems Center and USSF.
It is the fourth GPS III satellite delivered into the operational constellation in the past 12 months and the second in the past three months. Additionally, this is the first GPS III vehicle delivered to the warfighter through an expedited satellite control authority transfer process, which cuts ten days off the previous operational acceptance timeline.
