Planet Labs advances satellite communication with NASA CSP ground tests

by Staff Writers
San Francisco CA (SPX) Nov 06, 2023
In an innovative stride within the aerospace industry, Planet Labs PBC (NYSE: PL) has recently concluded a pivotal phase in their collaboration under NASA's Communications Services Project (CSP). This marks a significant milestone as they work to refine inter-satellite communication technologies, specifically satellite-to-satellite links.

As a key player in the domain of daily Earth data and insights, Planet was integrated as a subcontractor by SES Space and Defense alongside Telesat Government Solutions, late in the previous year. The collaboration was set with the ambitious goal to craft and demonstrate viable space-to-space connectivity solutions. These solutions are expected to function between Lower Earth Orbit (LEO) satellites, with a communication relay to other in-space assets managed by SES and Telesat.

The critical ground demonstration, taking place in late August, showcased the concerted efforts of Planet and SES Space and Defense. Executed from a simulation of a flight user terminal situated in Mountain View, California, the testing established communication with SES' NSS-9 geostationary orbit (GEO) satellite. To achieve this, Planet brought to the table flight representative radios developed internally, along with custom-designed spread spectrum waveforms. The testing apparatus also included both omnidirectional and directional antennas, purpose-built for the task.

The success of this ground demonstration has been pivotal. It has confirmed the efficacy of the radio and antenna designs, as well as the viability of the link margin, data rates, and latency. This positive outcome serves as an initial, yet crucial, leap in the maturation of technology necessary for delivering a real-time connectivity solution via Planet's LEO satellites. The end goal is to enhance the services offered to Planet's clientele, particularly those whose operations would significantly benefit from responsive, last-minute tasking capabilities.

Planet's proprietary RTcomms system has been designed with persistence, ubiquity, and near-real-time, low data rate intersatellite links in mind, utilizing global GEO C-band beams. Its notably spread waveform operates well within the acceptable limits of off-axis and spectral power density mandated for geostationary communication systems. The tailored antenna pattern, low power density, and directional output are calibrated to mitigate any perceptible interference with terrestrial communication systems. Furthermore, the waveform's design is such that it remains resilient to potential disruptions caused by other C-band satellites, thereby ensuring consistent and reliable operation across the globe.

Kiruthika Devaraj, the VP of Avionics and Spacecraft at Planet, shared her insights on the progress. She indicated that the ground demonstration campaign stands as a substantial advancement in Planet's ongoing efforts to furnish their clientele with the most current and actionable insights.

This development in intersatellite communication signifies an important step not only for Planet Labs but also for the wider satellite communication sector. By pushing the boundaries of current satellite communication capabilities, Planet is actively contributing to the broader field of space technology, enhancing the infrastructure that enables a wide array of Earth-observing satellites to relay information swiftly and reliably.

In the rapidly evolving landscape of satellite communications, achievements such as this are pivotal. They not only demonstrate technical proficiency and progress but also pave the way for more dynamic and efficient utilization of satellite constellations. For industry professionals and clients of Planet Labs, this could mean access to faster, more reliable data - a crucial factor in decision-making across various sectors. The success of these ground tests heralds a future where real-time, space-based communication could become the norm, revolutionizing our approach to managing and interpreting the vast amounts of data we collect from space. analysis

Such advancements could drastically improve data acquisition and management, fostering new opportunities for Earth observation and real-time data analytics.

For the Stock and Finance Market Analyst, this development is also highly relevant, scoring a 7 out of 10. The successful ground tests reflect positively on Planet Labs' potential for growth and innovation, possibly affecting their stock value (NYSE: PL). The collaboration with major entities like SES and Telesat under the NASA CSP could signal strong future partnerships and increased competitiveness in the market, making it an attractive prospect for investors.

Government Policy Analysts may assign a relevance score of 6 out of 10. While the direct implications for policy are less immediate than for industry or financial analysts, the advancements in satellite communications can influence policy related to space infrastructure, defense communications, and earth monitoring systems. Government agencies might be interested in leveraging these technologies for national security and environmental monitoring purposes.

When compared to the events and trends in the space sector over the past 25 years, this article showcases the continuing trend towards international collaboration and private-public partnerships in space technology development. The focus on improved communication technologies echoes the late 20th century's satellite communication revolution and builds on the increasing commercialization of space since then.

Correlations with past trends include the ongoing push for improved data communication technologies and international cooperation in space endeavors. A notable similarity is the continued interest in enhancing Earth observation capabilities, a trend that has remained significant since the launch of the first commercial remote sensing satellites. Discrepancies may arise in the pace of innovation and the scale of collaboration, which have both accelerated due to private sector involvement and global interest in space-based technologies.

Five investigative questions that analysts might consider are:

1. How does the Planet Labs' RTcomms system's performance compare with current satellite communication technologies in terms of latency and data throughput?

2. What are the projected cost implications for deploying these advanced satellite communication systems?

3. How might this technology impact the competitive landscape of the satellite communication market?

4. What are the potential applications of this technology for government operations, particularly in national security and environmental monitoring?

5. How do these advancements align with international regulations and standards for satellite communications?

These questions can help in understanding the broader implications of Planet Labs' recent technological advancements for different stakeholders involved in the space, finance, and government sectors.
