Skykraft forms international partnership

Skykraft has announced the formal signing of Participating Project Partner Agreement for the “Demonstration of Collaborative Position Navigation and Timing (PNT) in Low Earth Orbit (LEO)” project. Supported by an International Space Investment (ISI) India Projects grant from the Australian Government, this initiative marks a key step in supporting the growth of joint space projects between Australia and India. ISI India Projects broadly aligns with the India Economic Strategy to 2035, especially regarding the India-Australia Comprehensive Strategic Partnership and the Comprehensive Economic Cooperation Agreement – focusing on strengthening its bilateral relationships and activities with mutual understanding of common interests and shared values, in support of both countries’ prosperity.

The primary goal of the project is the development of next-generation collaborative PNT systems. PNT systems play a critical role in sectors such as transportation, communication, and infrastructure, however existing systems can be prone to errors. For example, the aviation industry has been particularly affected in a growing number of regions, with aircraft navigation systems being impacted or incorrect information being reported to Air Traffic Management (ATM) controllers.

The project will demonstrate the feasibility of large-scale constellations in LEO, address the vulnerability of existing Global Navigation Satellite Systems (GNSS) in denied environments, investigate additional applications for PNT signals that can be exploited from LEO and, through the demonstration of the resilience of large-scale constellations (which can be easily updated and reconstituted), provide a roadmap to enable collaborative LEO-PNT. www.skykraft.com.au

Court greenlights Ligado Networks’ $39 billion lawsuit

The U.S. Court of Federal Claims has allowed Ligado Networks to move forward with its $39 billion lawsuit against the federal government, marking a significant step in a long-running dispute over 5G spectrum usage and property rights.

The dispute stems from the FCC’s 2020 decision granting Ligado exclusive control over spectrum near GPS frequencies, raising concerns about potential interference with GPS systems. In its October 2023 lawsuit, Ligado accused the U.S. government of a “multiyear misinformation and disparagement campaign” to hide its actions and misappropriate Ligado’s licensed spectrum for DOD systems without permission or compensation.

The government sought to dismiss the lawsuit in January 2024, citing lack of jurisdiction and Ligado’s inability to prove a valid property interest in its FCC license. The core of the conflict lies in the proximity of Ligado’s L-band spectrum to GPS frequencies, which could interfere with critical GPS signals used for navigation, timing, and national security. The DOD, GPS companies, and industry officials have strongly opposed Ligado’s plan for a terrestrial 5G network, warning of harmful interference to GPS receivers.

JAVAD GNSS congratulates the GSP on groundbreaking success

JAVAD GNSS proudly extends its congratulations to the Gruyère Space Program (GSP) for their remarkable achievement in developing Colibri, the world’s first student-built reusable rocket hopper. With over 50 successful flights, including an ascent to 105 meters and a precise landing, Colibri represents a historic milestone in student-led aerospace innovation.

A critical component of this success was the TR-2S OEM GNSS receiver, engineered and manufactured by JAVAD GNSS. The receiver provided precise real-time positioning capabilities and maintained a 1cm fix throughout flight, enabling Colibri to achieve its ambitious goals. GSP’s successful deployment of the TR-2S highlights its robustness and performance under demanding conditions. Javad.com
