Key Terms
radio frequencytechnical
Radio frequency is the band of electromagnetic waves used to send wireless signals, like the invisible ripples that carry radio, mobile phone, Wi‑Fi and some medical-device signals through the air. Investors care because control, licensing, or interference of these frequencies affects how well wireless products and services work, the cost and availability of spectrum rights, and regulatory approvals — all of which can materially influence revenue, competition and risk for companies.
rf geolocationtechnical
RF geolocation uses radio signals to determine where a transmitter or device is located by comparing the timing, direction or strength of those signals at multiple receivers—think of it as triangulating the source of a sound but with radio waves. Investors care because it powers tracking, network diagnostics, security and regulatory compliance across telecom, logistics and public-safety services, so improvements or failures can directly affect revenue, costs and legal risk for related companies.
s-bandtechnical
S-band is a portion of the radio spectrum roughly between 2 and 4 gigahertz used for wireless links like satellite communications, weather and air-traffic radar, and some mobile services. For investors it matters because access to S-band frequencies and the gear that uses them can drive revenue or require regulatory approval — think of spectrum as traffic lanes for data: owning or getting a license to use those lanes can directly affect a company’s ability to offer services and compete.
x-bandtechnical
X-band is a slice of the microwave radio spectrum (roughly 8–12 gigahertz) used for radar, satellite communications and certain military and weather systems. Think of it like a particular station on a radio dial chosen because its wavelength works well for high-resolution radar and relatively compact satellite links; that makes it important for companies that build radars, satellite terminals, antennas and related chips. Investors watch X-band activity because demand, regulatory access to the spectrum and new product wins can drive revenue and competitive advantage in defense, aerospace and telecom supply chains.
gnss l-bandtechnical
GNSS L-band is the range of radio frequencies around 1–2 GHz used by global navigation satellite systems (like GPS, Galileo, BeiDou) to send positioning and precise timing signals to devices on the ground. Think of it as a set of dedicated highway lanes for location and clock information; its availability, quality, and protection matter to investors because businesses and infrastructure — from phones and delivery drones to telecom networks and financial trading systems — rely on those signals, and interference, regulation, or new uses of the spectrum can affect company revenues and risk.
geospatial intelligence (geoint)technical
Geospatial intelligence (GEOINT) is the analysis of imagery and location data from satellites, drones, maps and ground sensors to reveal what is happening where on Earth. It matters to investors because it turns remote signs — such as factory activity, shipping movements or land use changes — into timely, verifiable insight for assessing asset performance, supply‑chain risks, regulatory compliance and competitive trends, like using a live map to check a company’s real‑world operations.
rf intelligencetechnical
RF intelligence is the capture and analysis of radio signals—like Wi‑Fi, Bluetooth, radar or cellular transmissions—to detect devices, patterns or events in the physical world. Think of it as a digital ear that turns invisible radio chatter into useful information, such as tracking asset movements, monitoring device performance, or spotting unusual activity. For investors, RF intelligence can reveal operational advantages, competitive edge, security risks or new revenue opportunities tied to how companies collect and use real‑world signal data.
constellationtechnical
A constellation is a group of interconnected companies or assets that move together because they are affected by similar factors or industry trends. For investors, understanding these groupings helps identify patterns, manage risks, and spot opportunities by seeing how different parts of the market are linked and influenced by common forces.
On-orbit demonstration successfully identifies and geolocates S- and X-band radio frequency signal sources
VIENNA, Va.--(BUSINESS WIRE)--
Spire Global, Inc. (NYSE: SPIR) (“Spire” or “the Company”), a global provider of space-based data, analytics and intelligence, has successfully demonstrated single-satellite radio frequency (RF) geolocation techniques on orbit, including the detection and geolocation of S-band and X-band radio frequency signals.
Traditionally, RF geolocation relies on multiple satellites operating together to determine the origin of a signal. Spire’s single-satellite RF geolocation capability expands the company’s RF sensing capabilities by enabling the identification and geolocation of higher-frequency emitters, including S- and X-band signals, using sensors onboard a single satellite.
The satellite launched in late 2025 aboard SpaceX’s Bandwagon-4 mission and was co-funded by the Government of Luxembourg through an ESA Contract in the Luxembourg National Space Programme, LuxIMPULSE, managed by the Luxembourg Space Agency.
“Understanding activity across the radio frequency spectrum is increasingly critical for modern defense and security operations,” said Theresa Condor, Chief Executive Officer of Spire Global. “By successfully detecting and geolocating higher-frequency emitters such as S- and X-band signals — commonly used by radar and sensing systems critical to defense and national security missions — and demonstrating single-satellite RF geolocation, we are strengthening Spire’s ability to deliver RF intelligence supporting defense and national security missions worldwide.”
“Single-satellite RF geolocation allows us to expand the range of signals we can detect from space while improving the efficiency of how those capabilities are deployed,” said Gabriel Oehme, Chief Technology Officer at Spire Global. “By leveraging Spire’s vertically integrated satellite platform, we can rapidly test, deploy, and scale new sensing technologies across our constellation. Demonstrating this capability for higher-frequency emitters such as S- and X-band signals represents an important step in expanding Spire’s RF intelligence capabilities.”
Through its defense-grade, space-based RF intelligence platform, Spire enables customers to detect and act on critical signal activity anywhere on Earth. Spire’s RF geolocation capabilities now span multiple bands across the RF spectrum, including VHF, UHF, GNSS L-band, S-band, and X-band, providing precise emitter latitude and longitude locations along with associated signal characteristics. These data products are designed to integrate seamlessly into existing geospatial intelligence (GEOINT) workflows, enabling enhanced monitoring, analysis, and decision-making.
Spire (NYSE: SPIR) is a global provider of space-based data, analytics and space services, offering unique datasets and powerful insights about Earth so that organizations can make decisions with confidence in a rapidly changing world. Spire builds, owns, and operates a fully deployed satellite constellation that observes the Earth in real time using radio frequency technology. The data acquired by Spire’s satellites provides global weather intelligence, ship and plane movements, and spoofing and jamming detection to better predict how their patterns impact economies, global security, business operations and the environment. Spire also offers Space as a Service solutions that empower customers to leverage its established infrastructure to put their business in space. Spire has offices across the U.S., Canada, UK, Luxembourg and Germany. To learn more, visit spire.com.
