GNSS Testing for LEO 

World-leading innovation

World-leading innovation for an increasingly complex PNT landscape

The aim of GNSS testing is to understand how a GNSS-enabled device will perform in the infinite different circumstances of the real world. For this reason, realistic GNSS testing is crucial in the development and validation of positioning, navigation and timing systems that will perform in the hands of users. With the lack of repeatability and error tracing in real world testing, delivering realistic results depends on lab-based GNSS simulation and record & playback technologies.

Simulation and record & playback systems represent the state-of-the-art in lab-based testing for GNSS. With enhanced realism and the highest fidelity, the significant benefits of bridging the gap between lab and real-world testing can be realised. Foremost of these is to move more testing away from the field and into the cheaper, faster, and more scientific lab environment.

Learn how to create a realistic GNSS test environment in the lab to identify issues with your GNSS receiver. This eBook discusses considerations for realistic GNSS simulation and realistic RF record & playback solutions.

More industries are using CubeSats for communications and data services, with many containing GPS/GNSS receivers for orbit determination and timekeeping.

As commercial CubeSat use matures, onboard GNSS receiver performance must be thoroughly tested using simulation.

Interstellar Technologies is a Japanese start-up that operates in the growing LEO and commercial space segment. It delivers launch services for small satellites, offering a cost-effective and high-performance solution to organisations looking to take advantage of the benefits of LEO orbits.

Positioning, navigation and timing (PNT) are critical elements of the function of a launch vehicle, and its ability to deliver its payload into orbit as required. To deliver the level of service required, ZERO will use a custom navigation system comprising a bespoke GNSS receiver and inertial sensor integration.

CS Enabling the future

For the first time in over half a century, humans are going back to the moon. However, unlike the ground-breaking efforts of the1960s and 1970s, modern missions such as ESA’s Lunar Pathfinder will place greater demands on positioning, navigation, and timing (PNT) functions. This brings with it a set of challenges – some familiar to terrestrial PNT providers and users, and some unique to areas outside Earth’s frame of reference. Understanding and addressing these challenges, and developing working solutions, will be critical to success.

Enabling the LEO revolution

Astro Digital delivers an end-to-end service to CubeSat application developers, from concept through to deployment. However, the inability of their existing simulator to generate trackable GNSS signals was slowing their development cycles and adding significant risk. Without strong GNSS positioning performance, deployed satellites could be totally incapacitated, leading to loss of revenue and reputation.

Spirent’s GSS7000 is powering current and future development at Astro Digital, enabling customers to succeed with strong GNSS positioning performance.
